An international team led by the University of Geneva has measured the orbit of the planet GJ 3090 b and found it running backward. The planet circles its star in the direction opposite to the star's…

NASA says its Perseverance rover found rock formed from cooled magma, not the lakebed sediment mission scientists expected, in a band of ground called the Margin Unit, at the inner rim of Mars'…

Photograph the Andromeda galaxy in ordinary starlight and you get the poster image: a calm banded spiral, the nearest giant spiral to our own. Map the same galaxy in the radio glow of neutral…

On Oct. 24, 2025, Robert Wagner was doing something routine: checking the quality of a map of the whole Moon, stitched together from hundreds of frames taken years apart. The software he uses turns…

Researchers at two Chinese Academy of Sciences observatories have proposed a way for a single laser ranging station on the ground to read a satellite's identity and its orientation at the same time,…
