Researchers for half a century have tried — and failed — to use the motion of stars moving across the sky to discover planets that lie beyond the solar system. Now a team has finally used the method, ...

Though harmless itself, its passage through the solar system is helping researchers test the systems, partnerships and knowledge needed to keep Earth safe.

Astronomers have invented a new method for searching out and spotting exoplanets. It combines two previous methods—astrometry and direct imaging—to narrow down targets before confirming the presence ...

Astrometry uses the shift in a star’s position on the sky relative to other stars to infer the existence of orbiting planets. The movement of the extrasolar planet AF Lep b (white spot at about 10 ...

A new search engine will soon turn your night sky images into powerful research data and identify the twinkling objects in them with just the click of a button. The Astrometry.net database will hunt ...

Dive into NASA's ATLAS system as interstellar 3I/ATLAS nears Sun on 29 Oct 2025—no Earth hit, but astrometry campaign probes anomalies & ET tech theories. Facts on defense activation ...

Background. Relative astrometry at or below the microarcsec level with a 1 m class space telescope has been repeatedly proposed as a tool for exo-planet detection and characterization, as well as for ...

Chinese astronomers have proposed a space telescope survey program to search for habitable exoplanets some 32 light-years from Earth. This would be the world's first space exploration mission ...

The century-old brass telescope was broken in places and long past its useful life — but it captured Lennart Lindegren's heart. Forty years ago, when Lindegren was a graduate student at the Lund ...
