NASA has finished the engineering review of the heat shield that brought the Artemis II crew home, and reports nine spots of char loss on the shield's dish, against 103 after the uncrewed Artemis I…
A SpaceX Dragon cargo spacecraft docked to the International Space Station at 10:27 a.m. EDT on Oct. 15, 2026, delivering more than 6,300 pounds of food, supplies and equipment to the crew. NASA said…
A University of Warwick team has calculated what white dwarf stars would look like to the human eye, and reports that one of them, WD J1330+6435, would appear green. Nobody has photographed one: no…
A massive star serves the universe in two ways, and they arrive in order. While it lives, it floods its surroundings with ultraviolet light energetic enough to tear the electron off a hydrogen atom.…
Dr. Stephen Volz helped build America's satellite infrastructure. In a conversation with ALLATRA, he explains what the data is telling us about our planet and our future. When you check the weather…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found rings, gaps and cavities inside four of 11 very small planet-forming disks, a class of disk that had looked smooth…
Look closely at the Moon's highlands in a high-resolution photograph and the ground is not as dead as it looks. Thousands of low cliffs run across it, some only a few meters high, each one a thrust…
NASA says it has finished checking out the main camera on the Nancy Grace Roman Space Telescope and has brought the telescope's optics into focus. In a mission blog post dated Oct. 14, 2026, the…
Astronomers have traced a bright, curling radio source nicknamed the "Treble Clef" to a massive galaxy cluster hidden behind the plane of the Milky Way, and identified the source itself as a radio…
Almost everything anyone knows about when the Solar System began rests on a few pale specks inside meteorites. They are calcium-aluminum-rich inclusions, grains condensed from hot gas close to the…
Voyager Technologies' Griffin-1 lunar lander has finished its environmental test campaign at NASA's Jet Propulsion Laboratory in Southern California and has gone back to the company for final…
Researchers at Southwest Research Institute have built a way to feed sunspot groups detected on the far side of the Sun into a model that tracks how the Sun's magnetic field moves across its surface.…
