Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months.

WASHINGTON (Reuters) -Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how ...

Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

(CNN) — After decades of searching, astronomers have uncovered some of the strongest evidence yet of exoplanets orbiting Barnard’s Star, the nearest single star system to Earth. The four planets are ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

Far beyond the bright planets, in the dim outskirts of the Solar System, astronomers keep stumbling on objects that refuse to follow the rules. Around Neptune in particular, a handful of newly charted ...

WASHINGTON (Reuters) - Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - though they concluded that all of them are too hot ...

A sequence of events during the evolution of certain rocky planets orbiting M-dwarfs, the most common stars in the universe, creates an atmosphere that would be stable over time. This is true for more ...

Why it matters: Worlds similar to Earth are the most highly-prized discoveries amid the search for exoplanets. New techniques designed to make Earth-like planets outside the solar system easier to ...

Earth-orbiting satellites could begin colliding with one another in less than three days in a worst-case-scenario scenario — potentially triggering a runaway cascade that may render low Earth orbit ...
