Simple shift could make low Earth orbit satellites high capacity
Researchers have invented a technique that enables low Earth orbit satellite antennas to manage signals for multiple users at once, slashing costs and simplifying designs for communication satellites.
View ArticleHuge gamma-ray burst collection 'rivals 250-year-old Messier catalog'
Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it 'rivals the catalog of deep-sky objects created by Messier 250 years ago', astronomers say....
View ArticleEarly dark energy could resolve cosmology's two biggest puzzles
Physicists propose that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe...
View ArticleKeeping mold out of future space stations
Mold can survive the harshest of environments, so to stop harmful spores from growing on future space stations, a study suggests a way to prevent its spread.
View ArticleAstronomers detect black hole 'starving' its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars.
View ArticleMore black holes than expected in the early universe
With the help of NASA's Hubble Space Telescope, an international team of scientists has found more black holes in the early universe than has previously been reported. The new result can help...
View ArticleA wobble from Mars could be sign of dark matter
Watching for changes in Mars' orbit over time could be new way to detect passing dark matter, according to researchers.
View ArticleNASA's Webb provides another look into galactic collisions
Astronomers examined galaxy Arp 107 which has revealed a wealth of information about star-formation and how two galaxies collided hundreds of million years ago. Arp 107 is located 465 million...
View ArticleGargantuan black hole jets are biggest seen yet
Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back.
View ArticleMagnifying deep space through the 'carousel lens'
A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportunity to study cosmology.
View ArticleOrganic matter on Mars was formed from atmospheric formaldehyde
Researchers have developed a Martian atmospheric evolution model to propose a new theory about Mars's past.
View ArticleVolcanoes may help reveal interior heat on Jupiter moon
By staring into the hellish landscape of Jupiter's moon Io -- the most volcanically active location in the solar system -- astronomers have been able to study a fundamental process in planetary...
View ArticleEarly-universe quasar neighborhoods are indeed cluttered
Observations confirm astronomers' expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam's exceptionally wide field of view and special...
View ArticleAstronomers catch a glimpse of a uniquely inflated and asymmetric exoplanet
Astronomers have observed the atmosphere of a hot and uniquely inflated exoplanet using NASA's James Webb Space Telescope.
View ArticleLow gravity in space travel found to weaken and disrupt normal rhythm in...
Scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues...
View ArticleWebb discovers 'weird' galaxy with gas outshining its stars
The discovery of a 'weird' and unprecedented galaxy in the early Universe could 'help us understand how the cosmic story began', astronomers say. GS-NDG-9422 (9422) was found approximately one billion...
View ArticleMapping distant planets: 'Ridges', 'deserts' and 'savannahs'
Researchers examined Neptunian exoplanets -- these planets share similar characteristics to our own Neptune, but orbit outside of our solar system. Scientists discovered a new area called the...
View ArticleMars' missing atmosphere could be hiding in plain sight
New research suggests Mars' missing atmosphere -- which dramatically diminished 3.5 billion years ago -- could be locked in the planet's clay-covered crust. Water on Mars could have set off a chain...
View ArticleNASA's Hubble finds that a black hole beam promotes stellar eruptions
In a surprise finding, astronomers using NASA's Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to...
View ArticleESO telescope captures the most detailed infrared map ever of our Milky Way
Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects -- the most detailed one ever made. Using the European Southern Observatory's VISTA...
