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 ...

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

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 ...

The Planetary Society continues to fund the search for potentially hazardous comets and asteroids that orbit close to our planet by awarding Gene Shoemaker Near Earth Object Grants to five researchers ...

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 ...

A Sun-type star situated nearly 3,000 light-years from Earth has provided astronomers with a unique opportunity to observe an ...

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 ...

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 ...

The Orion Nebula (also known as M42) is one of the brightest nebulae in the night sky even visible to the naked eye; it appears as the middle “star” in the constellation Orion’s sword. This nebula is ...
