Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

NASA has found something that will help understand how the cosmos was when everything barely started. Imagine someone screams in a far away place and that ...

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life.

Astronomers have spent the past decade cataloguing thousands of planets beyond the solar system, many of them falling into a ...

A new discovery suggests the possibility of an exomoon with an unprecedentedly large mass, thousands of times larger than any ...

Realising that our solar system isn’t like most others out there has helped astronomers rewrite the story of how it formed ...

The supposed "strange signals" were not mysterious at all, but commonly observed transit signals, according to NASA.

A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing link in planet formation.

Since the Kepler Space Telescope began its prowl for exoplanets in 2009, it has uncovered a strange pattern among these alien worlds: their orbits follow a consistent rhythm. If one planet in a system ...

Daniel Apai is a professor of astronomy, planetary sciences and optical science at the University of Arizona. He receives funding from NASA. Exoplanets are worlds that orbit other stars. They are very ...

Since the early days of exoplanet discovery, astronomers have confirmed almost 4,200 worlds orbiting distant stars, as well as thousands of more candidates. And with those kinds of numbers, there are ...
