A new study published in Science marks the first time astronomers have directly measured the mass of a rogue planet, a ...

Astronomers believe the free-floating planet is around 22 percent the mass of Jupiter and lies 3,000 parsecs from the Milky ...

Astronomers have finally weighed a wandering “rogue” planet, uncovering a Saturn-mass world flung into the galaxy after a dramatic planetary breakup.

Their analysis showed that the planet lies about 3,000 parsecs, or just under 10,000 light-years, from Earth. Its mass is ...

In April, scientists captured global attention by announcing they’d found a molecule in a faraway planet’s atmosphere that could signal life there. But a new analysis by University of Chicago ...

A 3.5-gallon volume of deep space, specifically within the Milky Way's Orion-Cygnus Arm, would contain approximately 4 million neutrinos and about 13,000 gas atoms, predominantly hydrogen and helium.

"Returning the scientifically selected samples that await us on Mars, as part of a balanced portfolio, will help to ensure the US does not cede leadership in deep space to other nations, such as China ...
