Galaxy Cluster Abell 3158 | DESI Legacy Imaging Survey | NOIRLab

Galaxy Cluster Abell 3158 | DESI Legacy Imaging Survey | NOIRLab

This is an image centered on a relatively nearby galaxy cluster dubbed Abell 3158; light from these galaxies had a redshift value of 0.059, meaning that it traveled approximately 825 million years on its journey to Earth. The image is a small part of the DESI Legacy Imaging Surveys—a monumental six-year survey covering nearly half the sky.

The largest two-dimensional map of the sky ever made has grown even larger with the tenth data release from the DESI Legacy Imaging Surveys—a monumental six-year survey covering nearly half the sky. This new data release adds increased sky and wavelength coverage to the already completed surveys made with data from the National Science Foundation’s NOIRLab telescopes at Kitt Peak National Observatory in Arizona and Cerro Tololo Inter-American Observatory in Chile.


The Universe is teeming with galaxies, each brimming with billions of stars. Though all galaxies shine brightly, many are cloaked in dust while others are so distant that to observers on Earth they appear as little more than faint smudges. By creating comprehensive maps of even the dimmest and most-distant galaxies, astronomers are better able to study the structure of the Universe and unravel the mysterious properties of dark matter and dark energy. The largest such map to date has just grown even larger, with the tenth data release from the DOE’s Dark Energy Spectroscopic Instrument (DESI) Legacy Imaging Survey. 

The DESI Legacy Imaging Survey expands on the data included in two earlier companion surveys: the Dark Energy Camera (DECam) Legacy Survey and the Beijing-Arizona Sky Survey. Jointly these three surveys imaged 14,000 square degrees of the sky visible from the northern hemisphere using telescopes at NSF’s NOIRLab’s Kitt Peak National Observatory (KPNO) and Cerro Tololo Inter-American Observatory (CTIO) in Chile. 

This ambitious six-year effort involved three telescopes, one petabyte (1000 trillion bytes) of data, and 100 million CPU hours on one of the world’s most powerful computers at the US Department of Energy’s National Energy Research Scientific Computing Center.

NASA’s Next-Generation Spacesuits: A Behind-The-Scenes Look | CNBC

NASA’s Next-Generation Spacesuits: A Behind-The-Scenes Look | CNBC

NASA has been using the current spacesuits on the International Space Station for decades and they are showing their age. The agency has had issues not only with finding the proper sizes to fit its increasingly diverse astronaut corps, but also with degradation of some suit components. Now NASA is turning to two commercial companies: Axiom Space and Collins Aerospace, a subsidiary of Raytheon Technologies, to build and maintain its new generation of spacesuits. Under the Exploration Extravehicular Activity Services Contract, or xEVAS, NASA is providing Collins and Axiom, along with a number of their industry partners, with up to $3.5 billion through 2034. CNBC got a behind-the-scenes look at the new suit that Collins Aerospace is designing in collaboration with partners ILC Dover and Oceaneering. NASA hopes to use this new suit on the International Space Station by 2026.

Giant Black Holes on Collision Course | NASA's Chandra X-ray Observatory

Giant Black Holes on Collision Course NASA's Chandra X-ray Observatory

Astronomers have discovered the first evidence for giant black holes in dwarf galaxies on a collision course. This result from NASA’s Chandra X-ray Observatory has important ramifications for understanding how the first wave of black holes and galaxies grew in the early universe.

Collisions between the pairs of dwarf galaxies have pulled gas towards the giant black holes they each contain, causing the black holes to grow. Eventually the likely collision of the black holes will cause them to merge into much larger black holes. The pairs of galaxies will also merge into one.

Scientists think the universe was awash with small galaxies, known as “dwarf galaxies,” several hundred million years after the Big Bang. Most merged with others in the crowded, smaller volume of the early universe, setting in motion the building of larger and larger galaxies now seen around the local universe.

Dwarf galaxies by definition contain stars with a total mass less than about 3 billion times that of the Sun, compared to a total mass of about 60 billion Suns estimated for the Milky Way.

The earliest dwarf galaxies are impossible to observe with current technology because they are extraordinarily faint at their large distances. Astronomers have been able to observe two in the process of merging at much closer distances to Earth, but without signs of black holes in both galaxies.

Astronomers have found many examples of black holes on collision courses in large galaxies that are relatively close by, but searches for them in dwarf galaxies are much more challenging and until now had failed.

The new study overcame these challenges by implementing a systematic survey of deep Chandra X-ray observations and comparing them with infrared data from NASA’s Wide Infrared Survey Explorer, or WISE, telescope and optical data from the Canada-France-Hawaii Telescope.

Using this technique, a group of researchers identified two pairs of merging dwarf galaxies in separate galaxy clusters. The first is Abell 133, which is located about 760 million light-years away. The second is the galaxy cluster Abell 1758S, which is about 3.2 billion light-years from Earth.

Astronomers will use these systems as analogs for ones in the early universe, so they can drill down into questions about the first galaxies, their black holes, and star formation the collisions caused many billions of years ago.

A Sparkling New View of The Carina Nebula | Hubble

A Sparkling New View of The Carina Nebula | Hubble


This sparkling new image depicts a small section of the Carina Nebula, one of the NASA Hubble Space Telescope’s most-imaged objects. The Carina Nebula, NGC 3372, is an enormous cloud of gas and dust home to several massive and bright stars, including at least a dozen that are 50 to 100 times the mass of our Sun. It is an emission nebula, meaning that the intense radiation from its stars ionizes the gas and causes it to glow. This gas is widely and thinly spread out over a large area, earning it the added designation of a diffuse nebula. Carina is a dynamic area of the sky with bursts of star formation occurring alongside star death. As stars form and produce ultraviolet radiation, their stellar winds disperse the gas and dust around them, sometimes forming dark, dusty cloaks and sometimes creating empty patches for the stars to become clearly visible.

NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions

NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions


NASA’s newly redesigned RS-25 engine for future flights of the Space Launch System (SLS) rocket beginning with Artemis V, underwent its second hot fire test of the year on Wednesday, Feb. 22, 2023, at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. This is part of a planned 12-test series of the newly redesigned RS-25 engines. The engine operated at up to 111% power level—the same level needed to help power NASA’s Space Launch System (SLS). The test had a duration of 600 seconds, more than the length of time the engines must fire during an actual flight (about eight-and-a-half minutes).

The testing series supports production of new RS-25 engines by lead SLS engine contractor Aerojet Rocketdyne. The new engines will help power future Artemis missions to the Moon, beginning with Artemis V, as NASA explores the universe for the benefit of all.

Four RS-25 engines fire simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent to help power each SLS flight. NASA and Aerojet Rocketdyne modified 16 engines remaining from the Space Shuttle Program, which were proven flightworthy at Stennis for Artemis missions I through IV.

Every RS-25 engine that will help power SLS will be tested at NASA Stennis. RS-25 tests at the site are conducted by a combined team of NASA, Aerojet Rocketdyne, and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.

Through Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

Pluto: A Blue Farewell | NASA's New Horizons Mission

Pluto: A Blue Farewell | NASA's New Horizons Mission

This is the highest-resolution color departure shot of Pluto's receding crescent from NASA's New Horizons spacecraft, taken when the spacecraft was 120,000 miles (200,000 kilometers) away from Pluto. 

A blue halo glows around Pluto’s receding crescent in this parting image taken by NASA's New Horizons spacecraft on July 14, 2015. At the time of this shot, New Horizons was 120,000 miles (200,000 kilometers) away from Pluto.

Shown in approximate true color, the picture was constructed from a mosaic of six black-and-white images from the Long Range Reconnaissance Imager, with color added from a lower resolution Ralph/Multispectral Visible Imaging Camera color image.

Scientists believe the haze is a smog resulting from the action of sunlight on methane and other molecules in Pluto's atmosphere. This reaction produces a complex mixture of hydrocarbons that accumulate into small haze particles which scatter blue light. As they settle down through the atmosphere, the haze particles form numerous intricate horizontal layers that extend to altitudes of over 120 miles (200 kilometers).

Perspectives from NASA Engineer Jamesa Stokes for National Engineers Week

Perspectives from NASA Engineer Jamesa Stokes for National Engineers Week

Jamesa Stokes' path to being an engineer at NASA started out on a completely different road.

While she loved and excelled at math and science, she was also passionate about studio art, her first major in college. However, knowing that science can also be a creative pursuit, she switched to physics and embarked on a journey to NASA when she reached grad school.

Stokes, who received her bachelor’s degree in physics from Auburn University and a Ph.D. in materials science and engineering from Pennsylvania State University, was awarded a graduate fellowship to conduct research at NASA's Glenn Research Center.  She later became a NASA intern and converted to a full-time materials research engineer when she finished her Ph.D.

“Working at NASA means tackling the bigger problems we face for the benefit of society,” said Stokes. “My job is to develop and understand how advanced materials behave in the extreme environments of space. It will help protect not only the lives of astronauts, but also flight vehicles.”

Are you considering a STEM career? Stokes says there are many ways to reach your goal.

“There is no required path to becoming a scientist or engineer nor is there one way a scientist or engineer is supposed to act or look,” she said. “Never let anyone discourage you from pursuing what you like and remember that you can always be more than whatever societal conventions envision your future to be. Participate in STEM clubs and activities to figure out what makes you passionate about science and engineering.”

Ondrej Králik: "After sunset, bright Venus and Jupiter shines on the western horizon. The dark sky made it possible to observe the zodiacal light with all the beautiful winter constellations."

Zodiacal light is related to the Earth’s path through space, as the dust particles responsible for scattering the sunlight are all within a cloud that lies on the ecliptic plane (dubbed the zodiacal cloud).

Saturn's Rings & Titan Moon | NASA Cassini Mission

Saturn's Rings & Titan Moon | NASA Cassini Mission

Atlas is an inner satellite of Saturn which was discovered by Richard Terrile in 1980 from NASA Voyager spacecraft photos and was designated S/1980 S 28. In 1983, it was officially named after Atlas of Greek mythology, because it "holds the rings on its shoulders" like the Titan Atlas held the sky up above the Earth. The moon is also designated Saturn XV. Atlas has a roughly spherical center surrounded by a large and smooth equatorial ridge.
 
The Cassini spacecraft ended its mission on Sept. 15, 2017. Cassini's end involved a series of close Saturn passes, approaching within the rings, then an entry into Saturn's atmosphere to destroy the spacecraft. This method was chosen because it is necessary to ensure protection and prevent biological contamination to any of the moons of Saturn thought to offer potential habitability.

For more information about the Cassini-Huygens mission visit: https://saturn.jpl.nasa.gov and www.nasa.gov/cassini

The Cassini-Huygens mission was a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, California, managed the mission for NASA's Science Mission Directorate, Washington, D.C.

The Eponymous Spiral Galaxy NGC 691 | Hubble

The Eponymous Spiral Galaxy NGC 691 | Hubble


This image features the spiral galaxy NGC 691, imaged in fantastic detail by Hubble’s Wide Field Camera 3 (WFC3). This galaxy is the eponymous member of the NGC 691 galaxy group, a group of gravitationally bound galaxies that lie about 120 million light-years from Earth. 

Objects such as NGC 691 are observed by Hubble using a range of filters. Each filter only allows certain wavelengths of light to reach Hubble’s WFC3. The images collected using different filters are then colored by specialized visual artists who can make informed choices about which color best corresponds to which filter. By combining the colored images from individual filters, a full-color image of the astronomical object can be recreated. In this way, we can get remarkably good insight into the nature and appearance of these objects.
