First light for the innovative new instrument is anticipated in 2028. Spectre — once operational — will play a key role in ...

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.

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 team’s analysis points to a lensing object with a mass of 0.219 Jupiter masses, a touch lighter than Saturn or around 70 ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

Astronomers have spotted an Earth-sized planet drifting alone through the Milky Way, detected briefly by bent starlight, ...

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 ...

A study published in Science Advances sheds new light on the mysterious origins of free-floating planetary-mass objects (PMOs)—celestial bodies with masses between stars and planets. Led by Dr. Deng ...

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 ...
