In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Supermassive black holes, often considered the universe's most extreme objects, are now seen as cosmic predators that can slow star growth in galaxies millions of light-years ...

The formation of a black hole can be quite a violent event, with a massive dying star blowing up and some of its remnants collapsing to form an exceptionally dense object with gravity so ​strong not ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers ...

Artist impression of the planetary system with four planets,around a small red star,called LHS1903. Caption: Astronomers have long thought solar systems follow a simple pattern similar to our own: ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...

Astronomers have released the new results from the CAFFEINE survey, shedding new light on a long-standing mystery: what controls the efficiency of star formation in the densest parts of galaxies? In ...
