Researchers have used the Dark Energy Spectroscopic Instrument (DESI) to map nearly six million galaxies across 11 billion years of cosmic history, allowing them to study how galaxies clustered throughout time and investigate the growth of the cosmic structure. This complex analysis of DESI’s first-year data provides one of the most stringent tests yet of Einstein’s general theory of relativity.
Researchers used the Dark Energy Spectroscopic Instrument to map how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory of general relativity predicts.
New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) suggest that planet formation can occur even in harsh stellar environments previously thought to be inhospitable.An international team of astronomers used ALMA to capture high-resolution images of eight protoplanetary disks in the Sigma Orionis cluster, which is irradiated by intense ultraviolet light from a massive nearby star.
Dr. Michelle LaRue, an associate professor at the University of Canterbury, is revolutionizing wildlife ecology by using high-resolution satellite imagery to study emperor penguins from space.
Syed Ayaz, a researcher at The University of Alabama in Huntsville (UAH), has published a paper in Scientific Reports that builds on an earlier first-of-its-kind study that examined kinetic Alfvén waves (KAW) as a possible explanation for why the solar corona, the outermost layer of the sun’s atmosphere, is approximately 200 times hotter than the surface of the sun itself.
Cedars-Sinai investigators are one step closer to manufacturing stem cells in space, which could speed up the development of new medical therapies on Earth. The first published data from the experiments conducted on a private space mission appeared in the peer-reviewed Nature portfolio journal NPJ Microgravity.
Hubble witnessed a dwarf galaxy crashing through the Milky Way galaxy's gaseous halo and living to tell the tale...though a bit worse for wear!
After major refurbishments, the old Johannesburg Planetarium has been transformed into the state-of-the-art Wits Anglo American Digital Dome.
American University’s School of Communication (SOC) announced today that seasoned student journalist Gabe Castro-Root was selected to join an expedition to Antarctica where he will be reporting on the expedition.
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter helped the earliest stars and galaxies clump together.
The International Space Station research project will examine microgravity’s effect on heart tissue and is designed to better understand how microgravity affects the function of the human heart.
“Killer electrons” that travel at nearly light speed inside Earth's Van Allen belts — the zone that surrounds the planet and traps energetic charged particles — pose a major threat to equipment in space by causing malfunctions in electronics.
Ledia Shehu, a doctoral student at The University of Alabama in Huntsville (UAH), has been selected to receive a NASA Future Investigators in NASA Earth and Space Science and Technology (FINESST) grant for her proposal, “Physics-Based Multiscale Constitutive Model for ISRU-Based 3D-Printed Lunar Concrete.” The project seeks to develop a multiscale model for 3D-printed concrete using lunar materials by simulating lunar conditions.
The National Space Club (NSC), Huntsville Chapter, has selected Dr. Gary Zank at The University of Alabama in Huntsville (UAH) to receive the 2024 Distinguished Science Award. Zank is the Aerojet/Rocketdyne Chair in Space Science, as well as director of the Center for Space Physics and Aeronomic Research (CSPAR). The award was presented at the 36th Annual Dr.
A new generation of space materials left Earth this morning [02:29 GMT 05/11/2024] as they head to the International Space Station (ISS) to undergo testing in the brutal conditions of low Earth orbit.
NASA crew and ground-based scientists are sending blood cells to the International Space Station on November 4 to learn why astronauts have a higher risk of blood clots.
A group of institutions, including Argonne National Laboratory, received a $20 million grant from the U.S. National Science Foundation and Simons Foundation to establish an AI and astronomy institute called the NSF-Simons AI Institute for the Sky (SkAI).
Using data from NASA's JWST and Chandra X-ray Observatory, a team of U.S. National Science Foundation NOIRLab astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s ‘feast’ could help astronomers explain how supermassive black holes grew so quickly in the early Universe.
Combining the power of the Hubble and James Webb space telescopes, astronomers revisited the legendary star Vega and found a smooth disk surrounding it—a surprise to astronomers who expected to see evidence of one or more large planets plowing through the disk, which is common around other young stars. But Vega is forcing astronomers to rethink the range and variety of planetary systems around stars.
Argonne scientists are contributing to the success of the Legacy Survey of Space and Time through advanced simulation, analysis and collaborative partnership.
