Astronomers have detected an Earth-size planet candidate orbiting a nearby star once a year, making it a promising target for ...

Red Dwarf's scouse technician Dave Lister was the last human alive, a down-on-his-luck slobbish space-hero long before Peter ...

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a ...

In our solar system, Jupiter is the undisputed king. If you added more mass to Jupiter, it wouldn’t actually get much bigger ...

Volunteer astronomers sifting through infrared images from a retired NASA telescope have spotted a faint object racing ...

However, this phenomenon has an upper limit. The particles accelerated by the radiation belt release energy. Consequently, this release cancels the acceleration when the planet’s magnetic field ...

Astrological drama alert!

There's a whole slew of objects that astronomers aren't sure whether to classify as "failed stars" or "overgrown planets." ...

An artist’s impression of the stellar dimming event caused by a brown dwarf or super-Jupiter with massive rings (foreground) forming an opaque “saucer” through which some light from the star ...

Astronomers using W. M. Keck Observatory and Subaru Telescope on the Big Island’s Maunakea discovered a massive planet and a brown dwarf orbiting distant stars — two rare companions that deepen our ...
