Image: Hubble captures swirling galactic trio
The mass of dust and bright swirls of stars in this image are the distant galaxy merger IC 2431, which lies 681 million light-years from Earth in the constellation Cancer......»»
First Hints of a Planet Orbiting in a White Dwarf"s Habitable Zone
A distant white dwarf is surrounded by space rocks marching in perfect time. This observation offers hints of what may be the first planet we have detected in the habitable zone of one of these stellar corpses, suggesting that they might be just as g.....»»
Pursuing carbon neutrality and water security in China
China has promised to become carbon neutral before 2060 and has coupled this ambitious target with stringent limitations on industrial water use by 2030. An international team of IIASA researchers and Chinese colleagues explored the effects of simult.....»»
Symmetries Reveal Clues About the Holographic Universe
How might our universe emerge like a hologram out of a two-dimensional sheet? An infinitely distant “celestial sphere” could hold answers......»»
NASA beams back unexpected selfie of the Webb telescope from 1 million miles away
We thought we'd never see the giant James Webb Space Telescope ever again.The space observatory has traveled to its distant cosmic outpost, nearly a million miles from Earth. It doesn't carry any surveillance cameras dedicated to monitoring the instr.....»»
Distant galaxies and the true nature of dark matter
At the center of spiral galaxies—those near to us but also those billions of light-years away—there is a vast spherical region made up of dark matter particles. This region has two defining characteristics: a density that is constant out to a cer.....»»
NASA telescope spots highest-energy light ever detected from Jupiter
The planet's auroras are known to produce low-energy X-ray light. A new study finally reveals higher-frequency X-rays and explains why they eluded another mission 30 years ago......»»
James Webb powers on its science instruments: What comes next?
The James Webb Space Telescope will be able to observe some of the most distant and ancient galaxies now it is in its new home, in orbit around the sun. Although it will be several months before it can start gathering science data, the science instru.....»»
New study examines privacy and security perceptions of online education proctoring services
Educational institutions have had to transition to remote learning and exam taking. This has led to an increase in the use of online proctoring services to curb student cheating. In a first-of-its-kind study, researchers explored the security and pri.....»»
Low-Field MRI for New Imaging Possibilities, Fewer X-rays
Researchers at the Ohio State University Wexner Medical Center are using a new low-field MRI system that may expand the capabilities of MRI for patients with implanted devices, patients who require lung imaging, and obese patients. The system, which.....»»
The abyssal world: The last terra incognita of the Earth"s surface
The deep-ocean floor is the least explored ecosystem on the planet, despite covering more than 60 percent of the Earth surface. Largely unknown life in abyssal sediments, from benthic animals to microbes, helps to recycle and/or sequester the sinking.....»»

Do forests lead to more or fewer clouds? It depends
Large-scale deforestation, forest restoration, forest fires, and droughts all have one thing in common: Most research on these topics focuses on forest ecosystems' impact on carbon storage and release. Other effects of forests are less often explored.....»»
Exploring astronomy with X-rays
The recent launches of the James Webb Space Telescope (Webb) and the Imaging X-ray Polarimetry Explorer (IXPE) by NASA and its international partners are excellent reminders that the universe emits light or energy in many different forms. To fully in.....»»

Are the northern lights caused by "particles from the Sun"? Not exactly
What a spectacle a big aurora is, its shimmering curtains and colorful rays of light illuminating a dark sky. Many people refer to aurora as the northern lights (the aurora borealis), but there are southern lights too (the aurora australis). Either w.....»»
