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 ...

Do planetary systems also experience a turbulent childhood phase? Images captured by the ALMA telescope network provide a ...

Are they stars? Are they planets? Or are they neither? Some rogue planetary mass objects that wander the cosmos alone could be created when young star systems clash, meaning they represent an entire ...

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 ...

Astronomers have found a massive cloud of metallic winds orbiting a mystery object in space. The cloud was found when ...

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 ...

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 ...

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 ...

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months.
