It's estimated there may be trillions of rogue planets wandering through the Milky Way, unbound to any star. Since detecting ...

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

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

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 ...

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 ...

Astronomers have signalled the discovery of a planetary body roaming the Milky Way that is not gravitationally bound to the ...

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 ...

A new study suggests that a close encounter with a massive interstellar object, possibly eight times the mass of Jupiter, may have significantly altered the orbits of the four outer planets in our ...

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 ...

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 ...
