Most have been found via microlensing: their gravity acts as a lens that boosts the light of a background star in a ...

NASA's Transiting Exoplanet Survey Satellite (TESS) may have discovered its first free-floating, or "orphaned," planet. That's a planet roaming the cosmos without a star, all alone. The potential ...

Astronomers discovered FFPs (free floating planets- rogue planets) more than 20 years ago, using the United Kingdom Infrared Telescope in Hawaii. Since then, observers have spotted hundreds rogue ...

The new planets are what astronomers refer to as “free-floating planets” — a population of planets that are poorly defined. According to a new paper, data captured during the Microlensing ...

The James Webb Space Telescope (JWST) has identified half a dozen free-floating planets wandering alone in the Perseus ...

The researchers believe that rogue moons may actually outnumber free-floating planets, and be as common as stars. Once flung away from its host planet, the fate of a free-floating moon is ...

The free-floating planets would then have the added property of mixing the products of local biological evolution on a galaxy-wide scale. Since 1995, when the first extrasolar planet was reported, ...

A recent NASA study estimates that our galaxy contains more “free floating” planets than stars. That would put the number of benighted, exiled worlds into the hundreds of billions. All known ...

But they actually do exist in real life. Astronomers, who sometimes like to kill fun, call these worlds free-floating planets, which is not nearly as cool a term. Still, these interstellar ...
