Scientists have discovered more than 6,000 planets beyond our solar system. What if some of them aren't planets at all, but ...

Why don't planets fall into the stars they orbit if they're constantly being pulled by gravity?Lindsey CoughterRocky Mount, ...

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

Astronomers study planetary transits and atmospheric signals using interstellar object 3I/ATLAS, drawing on transit spectroscopy principles and recent observational constraints discussed by Avi Loeb.

Humanity has long wondered if we are being watched from the stars, but the answer might lie in our own exhaust fumes. As the ...

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 ...
