 This is how NASA took the groundbreaking black hole photo

black hole

The Event Horizon Telescope (EHT) project, a global network of radio telescopes, was responsible for capturing the black hole image that attracted attention from all across the world. A key component of this relationship was NASA.

Here is a quick explanation of the photo's composition:

1. Radio Interferometry: The Very Long Baseline Interferometry (VLBI) method was applied by the EHT to gather data from several telescopes in order to construct a virtual telescope with a diameter equivalent to the separation between the participating telescopes. This technique allowed for extremely high-resolution imaging.

2. Data Collection: From April 2017 to April 2018, eight telescopes around the world simultaneously observed two supermassive black holes: one in the center of our Milky Way galaxy (Sagittarius A*) and another in the neighboring galaxy Messier 87 (M87). The telescopes collected radio waves emitted by the surrounding matter as it fell into the black holes.

3. Data Synchronization: Precise time synchronization was crucial for combining the data from all the telescopes accurately. Atomic clocks were used to ensure precise timing across all sites.

4. Data Processing: The collected data was transported to a central processing facility, where it underwent a complex process called correlation. This process combined the data from all the telescopes to create an interferometric image.

5. Imaging: Advanced algorithms and computational techniques were employed to process the correlated data and reconstruct images of the black holes. The algorithms took into account the Earth's rotation and other factors to generate the final images.

It's important to note that the black hole images obtained by the EHT project are not direct photographs but are created through a combination of data and computational techniques. The accomplishment constitutes a tremendous scientific advance and provides important new information about black holes.

You can consult scientific publications and resources offered by the EHT cooperation and organizations participating, such as NASA and the National Science Foundation (NSF), for additional in-depth and technical information regarding the EHT project and the method of taking the black hole photographs.

Radio Interferometry: 

The NASA-led Event Horizon Telescope (EHT) project employed radio interferometry extensively to capture the first-ever image of a black hole. Here is a deeper look at how radio interferometry was used in this groundbreaking discovery:

1. Combining Telescopes: The EHT project made use of a number of radio telescopes, including the James Clerk Maxwell Telescope (JCMT) in Hawaii, the Submillimeter Array (SMA) in Hawaii, and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.  These telescopes were synchronized to observe the same black hole simultaneously.

2. Very Long Baseline Interferometry (VLBI): VLBI, a method used in radio interferometry, combines data from many telescopes to build a virtual telescope with a diameter equal to the greatest distance between the participating telescopes. The resolution increased as the separation grew larger.

3. Capturing Radio Waves: Both Sagittarius A*'s supermassive black hole and M87's location in the center of our Milky Way galaxy were the source of the radio waves that were picked up by the participating observatories.These radio waves have a greater ability than other wavelengths to enter the interstellar medium because of the heated gas that surrounds them.

4. Precise Time Synchronization: Accurate timing is crucial for radio interferometry. The participating telescopes were equipped with atomic clocks to ensure precise synchronization of the collected data. This synchronization allows the telescopes to combine their data effectively.

5. Data Correlation: After the observations, the data from each telescope was carefully calibrated and transported to a central location for correlation. The correlation process involved comparing the arrival times of the radio waves at each telescope, taking into account the differences due to their locations on Earth.

6. Image Reconstruction: Advanced computational techniques and algorithms were employed to process the correlated data and reconstruct an image of the black hole. These algorithms account for various factors, such as the Earth's rotation, to create a final image with high resolution and detail.

The EHT team was able to reach exceptional resolution and obtain the famous image of the black hole's event horizon by integrating the data from various telescopes via radio interferometry. This advance in imaging technology opens up new research directions for comprehending black holes, which are mysterious cosmic phenomenon.

Data Collection: 

Data collecting was a crucial step in the NASA-led Event Horizon Telescope (EHT) project, which resulted in the groundbreaking discovery of the first-ever photograph of a black hole. Here is an overview of the data acquired for this significant project:

1. Global Telescope Network: The EHT project utilized a network of radio telescopes located at various sites around the world. These telescopes were strategically positioned to maximize the coverage and resolution of the targeted black hole.

2. Simultaneous Observations: The collaborating telescopes observed two supermassive black holes between April 2017 and April 2018: one in the Messier 87 (M87) neighboring galaxy and one at the center of our Milky Way galaxy (Sagittarius A*). To gather as much information as we could, these observations were made concurrently.

3. Radio Wave Detection: The black holes emit radio waves from the hot gas swirling around them. The participating telescopes were designed to detect and capture these radio waves. Radio signals in the millimeter and submillimeter wavelengths were specifically targeted.

4. High-Frequency Data Collection: To achieve the necessary resolution to image the black hole's event horizon, the EHT project required high-frequency data collection. This involved observing the black holes at wavelengths shorter than what is typically used in traditional radio astronomy.

5. Long Observation Campaign: The data collection process spanned several months, allowing for an extended observation campaign. This extended duration provided more opportunities to gather a substantial amount of data and capture variations in the black hole's emissions.

6. Weather Conditions: Weather conditions played a crucial role in data collection. Clear skies and minimal atmospheric interference were necessary for optimal observations. The global nature of the telescope network helped mitigate the impact of unfavorable weather conditions at individual sites.

7. Data Storage and Transfer: The data collected by each telescope was stored and then transferred to a central location for further processing and analysis. The high volumes of data required efficient storage and transfer methods to ensure that all observations were properly captured.

The data collected by the participating telescopes formed the foundation for subsequent data processing, correlation, and imaging algorithms that led to the creation of the historic image of the black hole's event horizon. The success of the EHT project's data collection efforts opened up new possibilities for studying and understanding black holes in unprecedented detail.

Data Synchronization: 

Data synchronization played a critical role in the NASA-led Event Horizon Telescope (EHT) project, which captured the first-ever image of a black hole. Here's an overview of how data synchronization was achieved during this groundbreaking endeavor:

1. Precise Timing: Accurate timing is crucial in radio interferometry, which is the technique used by the EHT project. Each participating telescope needs to record the exact time at which it receives a radio signal from the black hole.

2. Atomic Clocks: To ensure precise timing, atomic clocks were used at each telescope site. Atomic clocks are highly accurate timekeeping devices that rely on the vibrations of atoms to measure time. They provided synchronized timing references across the entire EHT network.

3. Time Stamp Exchange: The participating telescopes exchanged time stamps with each other. These time stamps served as references for aligning the data collected by each telescope during the observation period.

4. Fiber Optic Network: The EHT project employed a dedicated fiber optic network to transfer the time stamp information among the telescopes. This network allowed for high-speed and reliable data transmission, minimizing delays and ensuring accurate synchronization.

5. Global Coordination: The EHT project involved telescopes located in different parts of the world. Global coordination was essential to account for variations in the Earth's rotation and to accurately align the observations made by telescopes in different time zones.

6. Correlation Center: After the observation period, the data collected by each telescope was sent to a central correlation center for processing. The correlation center utilized the time stamp information and sophisticated algorithms to align and combine the data from all the telescopes.

By synchronizing the data collection process across multiple telescopes, the EHT project ensured that the signals received from the black hole at different locations were properly aligned in time. This synchronization allowed for the precise combination of data during the correlation and imaging stages, ultimately resulting in the creation of the historic image of the black hole's event horizon.

Data Processing:

The NASA-led Event Horizon Telescope (EHT) project, which successfully obtained the first-ever image of a black hole, relied heavily on data processing. An summary of the data processing procedures used to make this ground-breaking finding is provided below:

1. Data Transfer: The data collected by each participating telescope was transported to a central processing facility. This involved transferring large volumes of data over specialized networks or physical storage media.

2. Calibration: The collected data underwent a calibration process to correct for instrumental and atmospheric effects. Calibration involved removing noise, compensating for instrumental biases, and accounting for variations caused by the Earth's atmosphere.

3. Fourier Transform: The calibrated data underwent a mathematical operation called the Fourier transform. This transformation converted the data from the time domain to the frequency domain. It allowed astronomers to analyze the data in terms of the specific frequencies present in the signals received from the black hole.

4. Correlation: The data from each telescope were correlated with the data from other telescopes to create an interferometric image. This correlation process involved combining the data while considering the time delays and phase differences between the telescopes, taking into account the precise timing and synchronization achieved during data collection.

5. Imaging Algorithms: Advanced imaging algorithms were employed to process the correlated data and reconstruct an image of the black hole. These algorithms used computational techniques such as CLEAN (an iterative algorithm for deconvolution) and other sophisticated methods to enhance the image resolution and clarity.

6. Validation and Analysis: The resulting image and data were carefully examined, and a number of validation approaches were used to make sure the conclusions were reliable and accurate. In order to assess the results' statistical significance, the observed data and the simulated data were compared.

7. Scientific Interpretation: Scientists and astrophysicists analyzed the data and image after processing to learn more about the characteristics and behavior of the black hole. This involved comparing the observations with existing theoretical models and pushing the boundaries of our understanding of these enigmatic cosmic objects.

The complex data processing pipeline employed by the EHT project was instrumental in transforming raw observational data into a high-resolution image of the black hole's event horizon.The project's data processing methods expanded our understanding of black holes and created new research opportunities for investigating these fascinating celestial phenomena.

Imaging:

The NASA-led Event Horizon Telescope (EHT) mission, which successfully obtained the first-ever image of a black hole, relied heavily on imaging. An overview of the imaging procedure used to make this ground-breaking finding is provided below:

1. Interferometric Imaging: The EHT project utilized a technique called very long baseline interferometry (VLBI) to create the image of the black hole's event horizon. VLBI involves combining the data collected by multiple radio telescopes scattered around the world to create a virtual Earth-sized telescope with unprecedented resolution.

2. Fourier Transform and Correlation: The raw data collected by the telescopes underwent a series of mathematical operations, including a Fourier transform. The Fourier transform converted the data from the time domain to the frequency domain, revealing the frequency components present in the observed signals. The data were then correlated to account for the time delays and phase differences between the telescopes, forming an interferometric image.

3. Imaging Algorithms:The associated data were processed by sophisticated imaging techniques to create an image of the black hole's event horizon. The CLEAN algorithm, an iterative deconvolution method, was one of the main techniques used. It improves the final image's clarity and resolution by assisting in the separation of the actual image from artifacts and noise.

4. Supermassive Black Hole Modeling: Theoretical models of supermassive black holes were employed to assist in the imaging procedure. These models incorporated knowledge about black hole physics and the behavior of surrounding matter, allowing scientists to interpret and reconstruct the observed data into an image.

5. Validation and Iteration: The imaging process involved iterative refinement to ensure the accuracy and reliability of the final image. The reconstructed image was compared with simulated data and cross-checked against different imaging algorithms to validate the findings. The process underwent rigorous scrutiny to establish the credibility of the image.

The ensuing image, which showed the black hole's shadow against its brilliant surroundings, corroborated Einstein's general theory of relativity's predictions and offered ground-breaking proof that black holes exist. The EHT project's imaging methods altered our understanding of and capacity for seeing these cosmic objects, opening up fresh vistas in astrophysics.

You Won't Believe What James Webb's Images Reveal About Jupiter's Auroras!

James Webb’s Jupiter Images Showcase Auroras, Hazes

With giant storms, powerful winds, auroras, and extreme temperature and pressure conditions, Jupiter has a lot going on. Now, the NASA/ESA/CSA James Webb Space Telescope has captured new images of the planet. Webb’s Jupiter observations will give scientists even more clues to Jupiter’s inner life.

 With giant storms, effective winds, auroras, and intense temperature and pressure conditions, Jupiter has a lot going on. Now, NASA’s James Webb Space Telescope has captured new pictures of the planet. Webb’s Jupiter observations will provide scientists even more clues to Jupiter’s internal life.

“We hadn’t really expected it to be this good, to be honest,” stated planetary astronomer Imke de Pater, professor emerita of the University of California, Berkeley. De Pater led the observations of Jupiter with Thierry Fouchet, a professor at the Paris Observatory, as section of an worldwide collaboration for Webb’s Early Release Science program. Webb itself is an worldwide mission led via NASA with its companions ESA (European Space Agency) and CSA (Canadian Space Agency). “It’s actually remarkable that we can see details on Jupiter collectively with its rings, tiny satellites, and even galaxies in one image,” she said.

The two pictures come from the observatory’s Near-Infrared Camera (NIRCam), which has three specialised infrared filters that exhibit details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum. Generally, the longest wavelengths appear redder and the shortest wavelengths are proven as extra blue. Scientists collaborated with citizen scientist Judy Schmidt to translate the Webb information into images.

In the standalone view of Jupiter, created from a composite of quite a few pics from Webb, auroras extend to excessive altitudes above each the northern and southern poles of Jupiter. The auroras shine in a filter that is mapped to redder colors, which additionally highlights light reflected from lower clouds and higher hazes. A extraordinary filter, mapped to yellows and greens, indicates hazes swirling around the northern and southern poles. A 1/3 filter, mapped to blues, showcases light that is mirrored from a deeper major cloud.

The Great Red Spot, a well-known storm so huge it ought to swallow Earth, seems white in these views, as do other clouds, due to the fact they are reflecting a lot of sunlight.

“The brightness here indicates excessive altitude – so the Great Red Spot has high-altitude hazes, as does the equatorial region,” stated Heidi Hammel, Webb interdisciplinary scientist for solar system observations and vice president for science at AURA. “The numerous bright white ‘spots’ and ‘streaks’ are probably very high-altitude cloud tops of condensed convective storms.” By contrast, dark ribbons north of the equatorial region have little cloud cover.

In a wide-field view, Webb sees Jupiter with its faint rings, which are a million instances fainter than the planet, and two tiny moons known as Amalthea and Adrastea. The fuzzy spots in the lower background are probably galaxies “photobombing” this Jovian view.

“This one picture sums up the science of our Jupiter device program, which research the dynamics and chemistry of Jupiter itself, its rings, and its satellite system,” Fouchet said. Researchers have already begun examining Webb statistics to get new science consequences about our solar system’s largest planet.  

Data from telescopes like Webb doesn’t arrive on Earth neatly packaged. Instead, it consists of statistics about the brightness of the light on Webb’s detectors. This data arrives at the Space Telescope Science Institute (STScI), Webb’s mission and science operations center, as raw data. STScI procedures the information into calibrated documents for scientific analysis and gives you it to the Mikulski Archive for Space Telescopes for dissemination. Scientists then translate that statistics into pictures like these all through the course of their research (here’s a podcast about that). While a crew at STScI formally strategies Webb photos for respectable release, non-professional astronomers recognized as citizen scientists regularly dive into the public statistics archive to retrieve and method images, too.

Judy Schmidt of Modesto California, a longtime photograph processor in the citizen science community, processed these new views of Jupiter. For the photo that consists of the tiny satellites, she collaborated with Ricardo Hueso, a co-investigator on these observations, who research planetary atmospheres at the University of the Basque Country in Spain.

Schmidt has no formal instructional background in astronomy. But 10 years ago, an ESA contest sparked her insatiable ardour for picture processing. The “Hubble’s Hidden Treasures” competition invited the public to discover new gems in Hubble data. Out of almost 3,000 submissions, Schmidt took home third place for an photograph of a newborn star.

Since the ESA contest, she has been working on Hubble and different telescope statistics as a hobby. “Something about it simply caught with me, and I can’t stop,” she said. “I should spend hours and hours each day.”

Her love of astronomy photographs led her to process pictures of nebulae, globular clusters, stellar nurseries, and greater astounding cosmic objects. Her guiding philosophy is: “I strive to get it to seem natural, even if it’s now not something shut to what your eye can see.” These snap shots have caught the interest of expert scientists, together with Hammel, who before collaborated with Schmidt on refining Hubble photos of comet Shoemaker-Levy 9’s Jupiter impact.

Jupiter dominates the black background of space. The planet is striated with swirling horizontal stripes of neon turquoise, periwinkle, light pink, and cream. The stripes engage and combine at their edges like cream in coffee. Along each of the poles, the planet glows in turquoise. Bright orange auroras glow simply above the planet’s floor at each poles.

A wide-field view showcases Jupiter in the higher proper quadrant. The planet’s swirling horizontal stripes are rendered in blues, browns, and cream. Electric blue auroras glow above Jupiter’s north and south poles. A white glow emanates out from the auroras. Along the planet’s equator, rings glow in a faint white. At the some distance left part of the rings, a moon seems as a tiny white dot. Slightly similarly to the left, every other moon glows with tiny white diffraction spikes. The relaxation of the photograph is the blackness of space, with faintly glowing white galaxies in the distance.

Jupiter is clearly more difficult to work with than extra far-off cosmic wonders, Schmidt says, due to the fact of how speedy it rotates. Combining a stack of photos into one view can be difficult when Jupiter’s different elements have turned around in the course of the time that the pictures had been taken and are no longer aligned. Sometimes she has to digitally make changes to stack the photographs in a way that makes sense.

Webb will supply observations about each section of cosmic history, however if Schmidt had to pick out one element to be excited about, it would be extra Webb views of star-forming regions. In particular, she is interested by way of younger stars that produce effective jets in small nebula patches known as Herbig–Haro objects. “I’m certainly searching ahead to seeing these bizarre and exquisite baby stars blowing holes into nebula's,” she said.

JWST captures rare star right before it goes supernova

 

James Webb Space telescope captures rare star right before it goes supernova

The uncommon sight of a Wolf-Rayet star – amongst the most luminous, most massive, and most quickly detectable stars acknowledged – used to be one of the first observations made by way of NASA’s James Webb Space Telescope in June 2022. Webb indicates the star, WR 124, in exceptional element with its effective infrared instruments. The star is 15,000 light-years away in the constellation Sagitta.

Massive stars race via their life cycles, and solely some of them go via a short Wolf-Rayet segment earlier than going supernova, making Webb’s exact observations of this uncommon segment treasured to astronomers. Wolf-Rayet stars are in the technique of casting off their outer layers, ensuing in their attribute halos of gasoline and dust. The star WR 124 is 30 instances the mass of the Sun and has shed 10 Suns’ worth of material – so far. As the ejected fuel strikes away from the star and cools, cosmic dirt varieties and glows in the infrared mild detectable through Webb.

The beginning of cosmic dirt that can continue to exist a supernova blast and make a contribution to the universe’s ordinary “dust budget” is of exquisite activity to astronomers for more than one reasons. Dust is fundamental to the workings of the universe: It shelters forming stars, gathers collectively to assist structure planets, and serves as a platform for molecules to structure and clump collectively – which include the constructing blocks of existence on Earth. Despite the many indispensable roles that dirt plays, there is nevertheless greater dust in the universe than astronomers’ modern dust-formation theories can explain. The universe is running with a dirt price range surplus.

Webb opens up new chances for analyzing important points in cosmic dust, which is first-rate found in infrared wavelengths of light. Webb’s Near-Infrared Camera (NIRCam) balances the brightness of WR 124’s stellar core and the knotty important points in the fainter surrounding gas. The telescope’s Mid-Infrared Instrument (MIRI) displays the clumpy shape of the fuel and dirt nebula of the ejected material now surrounding the star. Before Webb, dust-loving astronomers truly did now not have sufficient targeted facts to discover questions of dirt manufacturing in environments like WR 124, and whether or not the dirt grains have been massive and bountiful adequate to live to tell the tale the supernova and end up a good sized contribution to the average dirt budget. Now these questions can be investigated with actual data.

Stars like WR 124 additionally serve as an analog to assist astronomers apprehend a vital duration in the early records of the universe. Similar demise stars first seeded the younger universe with heavy factors cast in their cores – factors that are now frequent in the present day era, which includes on Earth.

Webb's unique image of WR 124 captures a fleeting, chaotic moment of change and ensures that further research will reveal the long-guarded secrets of cosmic dust.

The best observatory for home science is the James Webb Space Telescope. Webb will explore the unfathomable structures and beginnings of our cosmos and our region within it, as well as solve puzzles in our solar system and distant planets revolving around other stars. Webb is an worldwide software led by way of NASA with its partners, ESA (European Space Agency), and CSA (Canadian Space Agency).

Why is Webb's observation a unique occurrence?

Because only a small percentage of big stars undergo a brief Wolf-Rayet phase before going supernova, Webb's detailed observations are extremely rare.

The photo shows Wolf-Rayet stars in the process of shedding their outer layers, which is what gives them their distinctive gas and dust halos. With a mass thirty times that of the Sun, star WR 124 has already shed material equivalent to ten Suns. According to the US space agency, cosmic dust develops and glows in the infrared light that Webb can detect when the expelled gas cools and moves away from the star.

How helpful is Wolf-Rayet phase observation for scientists?

According to NASA, cosmic dust contributes to the universe's overall "dust budget" and can sustain supernova explosions, therefore understanding its origin is crucial for astronomers.

The basis of life on Earth is dust, which is also essential to the universe's operation.

 According to NASA, dust shields newborn stars, aids in the formation of planets, and gives molecules a surface on which to congregate and cluster. It also begs the interesting issue of why the cosmos is more dusty than current dust-formation theories anticipate, given all the vital functions that dust performs in the universe.

In addition to promising future discoveries that will unlock the long-kept secrets of cosmic dust, NASA stated that Webb's comprehensive image of WR 124 "preserves forever a brief, turbulent time of transformation."

James Webb Space Telescope

James Webb Space Telescope

NASA's much awaited James Webb Space Telescope (JWST), which replaced the Hubble Space Telescope, was launched on December 25, 2021. The project incurred substantial cost overruns; the original $0.5 billion budget was later expanded to almost $10 billion. Work on the project started in 1996.

JWST reached a major mission milestone on January 8, 2022, when it achieved complete deployment. 

 The telescope reached its designated destination on January 24, positioning itself to commence its groundbreaking observations of the universe. The deployment and arrival at its destination are critical steps in ensuring the functionality and success of the mission, allowing JWST to contribute to our understanding of the cosmos. it arrived at its destination.On March 16, 2022, it focused all its mirrors on a single star for the first time.

On July 12, 2022, NASA released JWST's initial set of full-resolution science images, featuring the Carina Nebula, the Eight-Burst Nebula, Stephan’s Quintet (a group of galaxies), and a galaxy cluster. Additionally, NASA presented an analysis of the composition of the exoplanet WASP-96b and discreetly unveiled an image of Jupiter.

Shortly after, researchers identified the oldest galaxy ever discovered in JWST data. This galaxy dates back to just 300 million years after the big bang, making it 100 million years older than the previously identified oldest galaxy, GN-z11.

How does the James Webb Space Telescope (JWST) work?

The James Webb Space Telescope (JWST) operates similarly to traditional telescopes by capturing and focusing light to extend our view of the cosmos. However, it diverges by observing in the infrared part of the electromagnetic spectrum, detecting heat instead of visible light like our eyes. This capability, similar to a night vision camera, allows JWST to study cooler and more distant celestial objects. Its significant size enhances light collection, aiding in the observation of fainter and smaller entities. Being in space eliminates atmospheric interference, providing clearer and more detailed data, making JWST a powerful tool for exploring the universe.

How far can the James Webb Space Telescope "see"?

Why is it that galaxies in the early universe are visible to the JWST because of this far-off view? Something is moving away from us faster the further distant it is in the universe. Redshift, which is experienced by fast objects, causes the item to appear redder. Something that is extremely far away eventually turns redder than red and enters the infrared spectrum. JWST's ability to view farther than previous telescopes is due to this. The oldest items are those that are farthest away since light takes time to reach us. Time travel is possible with telescopes like Hubble and JWST. Because JWST operates in the infrared, it can see farther than Hubble and almost all the way back to 13.7 billion years ago, when the cosmos first began.

The James Webb Space Telescope is currently where?

The L2 Lagrange point is the location around which the JWST revolves. This is 1.5 million kilometers beyond Earth so that Earth's heat will not obstruct its view. Because L2 is a gravity well, we don't need as much fuel to maintain it there as we would if it were floating aimlessly in space. The fact that L2 circles the sun with us is also helpful because it means we can always talk to each other and download pictures from the telescope.
