Blue Origin achieved a major reusability milestone with New Glenn, yet the mission also exposed how far the company still has to go after its payload was left in a lower-than-planned orbit.

A study highlighted by Universe Today found that smaller Trojan asteroids near Jupiter do not show the same clear color split seen in larger objects, opening a new puzzle about the early solar system.

Using early survey data collected before the start of its flagship sky-mapping campaign, the Vera C. Rubin Observatory has already added 11,000 newly identified asteroids to the Solar System inventory.

A new simulation study helps explain why some stars torn apart by supermassive black holes trigger spectacular flares, offering astronomers a better way to interpret tidal disruption events.

Researchers using lunar regolith simulant say less weathered, coarser-grained soil similar to material expected near the Moon’s south polar region may be suitable for rover traffic without raising major dust clouds.

A new White House policy memo tells the Pentagon and NASA to move quickly on nuclear reactors for orbit and the Moon, with demonstrations targeted as early as 2028 and 2030.

A large study highlighted by Gizmodo found that observations of the universe’s biggest structures remain consistent with Newtonian and Einsteinian gravity, weakening the case that modified gravity alone explains cosmolog

A Starlink mission from Vandenberg Space Force Base is set to test another marker in SpaceX reusability: the company’s 600th Falcon booster landing attempt, using booster B1097 on its seventh flight.

Blue Origin has completed a static fire of the first previously flown New Glenn booster, a step that could clear the way for a launch of AST SpaceMobile’s BlueBird-7 satellite as soon as Sunday, April

A new SpaceNews commentary argues that Artemis 2's success strengthens the case for human exploration, even as proposed budget cuts threaten NASA's ability to sustain it.

A new Universe Today explainer walks through the physics behind Cherenkov radiation by focusing on a deceptively simple question: why does light travel more slowly through matter than through vacuum?

Using HETDEX data, astronomers report tens of thousands of giant hydrogen gas halos around galaxies from 10 to 12 billion years ago, offering new support for ideas about how early galaxies grew during cosmic dawn

A historian of Apollo describes Artemis 2 as the moment human lunar exploration shifted from remembrance to renewal, anchored by new images from the crew’s trip around the moon.

New observations of 29 Cygni b with the James Webb Space Telescope are giving astronomers fresh evidence about how extremely massive gas giants may form and where the boundary between planets and stars begins.

A new White House roadmap calls for NASA, the Department of Defense, and the Department of Energy to develop nuclear reactors for orbit and the lunar surface, with key milestones set for 2028 and 2030.

The US Space Force says reliability issues with ULA’s Vulcan rocket are shaping future launch-buying decisions and could shift more missions toward SpaceX.

A new NASA Earth Observatory image highlights subtle ridges and frozen channels along James Bay, where land is still rebounding from the weight of the Laurentide Ice Sheet thousands of years after the last glacial

NASA says James Webb Space Telescope observations of 29 Cygni b found evidence for heavy elements including carbon and oxygen, supporting the idea that the 15-Jupiter-mass object formed like a planet.

On April 14, only 13% of the Moon is illuminated, marking the final stretch before the New Moon and leaving little of the lunar surface visible without optical aid.

NASA imagery shows Super Typhoon Sinlaku approaching the Mariana Islands after intensifying into a violent typhoon with sustained winds near 280 kilometers per hour unusually early in the Pacific season.
