Six Ways Supercomputing Advances Our Understanding of the Universe

November 15, 2024 NeRD

At NASA, high-end computing is essential for many agency missions. This technology helps us advance our understanding of the universe – from our planet to the farthest reaches of the cosmos. Supercomputers enable projects across diverse research, such as making discoveries about the Sun’s activity that affects technologies in space and life on Earth, building artificial intelligence-based models for innovative weather and climate science, and helping redesign the launch pad that will send astronauts to space with Artemis II. These projects are just a sample of the many on display in…

Repair Kit for NASA’s NICER Mission Heading to Space Station

July 30, 2024 NeRD

4 min read Repair Kit for NASA’s NICER Mission Heading to Space Station NASA will deliver a patch kit for NICER (Neutron star Interior Composition Explorer), an X-ray telescope on the International Space Station, on the agency’s Northrop Grumman 21st commercial resupply mission. Astronauts will conduct a spacewalk to complete the repair. Located near the space station’s starboard solar array, NICER was damaged in May 2023. The mission team delivered the patch kit to NASA’s Johnson Space Center in Houston in May 2024 so it could be prepped and packed…

NASA’s Chandra Peers Into Densest and Weirdest Stars

June 20, 2024 NeRD

Supernova remnant 3C 58. X-ray: NASA/CXC/ICE-CSIC/A. Marino et al.; Optical: SDSS; Image Processing: NASA/CXC/SAO/J. Major The supernova remnant 3C 58 contains a spinning neutron star, known as PSR J0205+6449, at its center. Astronomers studied this neutron star and others like it to probe the nature of matter inside these very dense objects. A new study, made using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, reveals that the interiors of neutron stars may contain a type of ultra-dense matter not found anywhere else in the Universe. In this image of 3C…

Investigating the Origins of the Crab Nebula With NASA’s Webb

June 17, 2024 NeRD

6 Min Read Investigating the Origins of the Crab Nebula With NASA’s Webb This image by NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) shows different structural details of the Crab Nebula. New data revises our view of this unusual supernova explosion. A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that…

NASA’s Tiny BurstCube Mission Launches to Study Cosmic Blasts

4 min read NASA’s Tiny BurstCube Mission Launches to Study Cosmic Blasts BurstCube, shown in this artist’s concept, will orbit Earth as it hunts for short gamma-ray bursts. NASA’s Goddard Space Flight Center Conceptual Image Lab NASA’s BurstCube, a shoebox-sized satellite designed to study the universe’s most powerful explosions, is on its way to the International Space Station. The spacecraft travels aboard SpaceX’s 30th Commercial Resupply Services mission, which lifted off at 4:55 p.m. EDT on Thursday, March 21, from Launch Complex 40 at Cape Canaveral Space Force Station in…

NASA Telescopes Find New Clues About Mysterious Deep Space Signals

February 14, 2024 NeRD

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in green) can influence the flow of electrically charged material from the object, which is a type of neutron star. NASA/JPL-Caltech Using two of the agency’s X-ray telescopes, researchers were able to zoom in on a dead star’s erratic behavior as it released a bright, brief burst of…

What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays!

February 5, 2024 NeRD

3 min read What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays! A flash of lightning. A roll of thunder. These are normal stormy sights and sounds. But sometimes, up above the clouds, stranger things happen. Our Fermi Gamma-ray Space Telescope has spotted bursts of gamma rays – some of the highest-energy forms of light in the universe – coming from thunderstorms. Gamma rays are usually found coming from objects with crazy extreme physics like neutron stars and black holes. So why is Fermi seeing them come from thunderstorms? About a thousand times a…

Hubble Finds Weird Home of Farthest Fast Radio Burst

January 9, 2024 NeRD

5 min read Hubble Finds Weird Home of Farthest Fast Radio Burst A NASA Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory’s Very Large Telescope…
