Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune ...

The star system V1298 Tau reveals that many planets begin as large, low-density worlds that slowly shrink and shed their ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one ...

A new report explains a young star system where low-density planets show how super-Earths and sub-Neptunes begin to form, based on new findings from the V1298 system ...

New research tracks young planets around a nearby star, showing how large, gas-rich worlds shrink over time to become the most common planets in the galaxy ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars — sometimes thousands of astronomical ...

Imagine studying the formation of a star 5 million years in the making, a newborn in the jargon of astronomers, that's tucked away in a "cosmic nursery" light-years away and yielding two growing ...

Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...
