Deposits of ice in lunar dust and rock (regolith) are more extensive than previously thought, according to a new analysis of data from NASA's LRO (Lunar Reconnaissance Orbiter) mission. Ice would be a...
View ArticleA new era of solar observation
For the first time, scientists have taken near-daily measurements of the Sun's global coronal magnetic field, a region of the Sun that has only been observed irregularly in the past. The resulting...
View ArticleIn odd galaxy, NASA's Webb finds potential missing link to first stars
Looking deep into the early universe with NASA's James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas...
View ArticleWinds of change: James Webb Space Telescope reveals elusive details in young...
Planet-forming disks, maelstroms of gas and dust swirling around young stars, are nurseries that give rise to planetary systems, including our solar system. Astronomers have discovered new details of...
View ArticleNew insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life -- with evidence for widespread...
View ArticleNASA's Hubble watches Jupiter's Great Red Spot behave like a stress ball
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises -- especially when NASA's...
View ArticleLightning strikes kick off a game of electron pinball in space
When lightning cracks on Earth, especially high-energy electrons may fall out of Earth's inner radiation belt, according to a new study -- an electron 'rain' that could threaten satellites, and even...
View Article'Inside-out' galaxy growth observed in the early universe
Astronomers have used the NASA/ESA James Webb Space Telescope (JWST) to observe the 'inside-out' growth of a galaxy in the early universe, only 700 million years after the Big Bang.
