Scientists have discovered more than 6,000 planets beyond our solar system. What if some of them aren't planets at all, but ...

The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth – ended its mission and burned on reentering the atmosphere after ...

The cast of exoplanets has an extraordinary new member. Using ESO’s telescopes, astronomers have discovered an approximately seven- Jupiter-mass companion to an object that is itself only twice as ...

Some of the most puzzling worlds in our telescopes’ catalogs may not be worlds at all, but relics from the first instants ...

This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

It's estimated there may be trillions of rogue planets wandering through the Milky Way, unbound to any star. Since detecting our first ones, we have been presented with an odd mystery.

When a star is young, it is often still surrounded by a primordial rotating disk of gas and dust, from which planets can form. Astronomers like to find such disks because they might be able to catch ...

Humanity has long wondered if we are being watched from the stars, but the answer might lie in our own exhaust fumes. As the ...

How do rogue planetary-mass objects -- celestial bodies with masses between stars and planets -- form? An international team of astronomers has used advanced simulations to show that these enigmatic ...
