Astronomers have confirmed a Saturn-size world drifting alone in deep space roughly 10,000 light-years from Earth, a ...

Rogue planets — worlds that drift through space alone without a star — largely remain a mystery to scientists. Now, ...

Universe Today reports on a new telescope proposal that could help astronomers detect Earth-sized exomoons, explaining current limits, future technology, and why moons around distant planets matter ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

The team’s analysis points to a lensing object with a mass of 0.219 Jupiter masses, a touch lighter than Saturn or around 70 ...

The search for life beyond Earth is a key driver of modern astronomy and planetary science. The U.S. is building multiple major telescopes and planetary probes to advance this search. However, the ...
