For almost a decade, astronomers have been searching for a ninth planet in the solar system. Recently, new evidence of ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

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 ...

The find represents the first clear detection of a baby planet taking shape within a disc of dust and gas with multiple rings. The ground-breaking discovery was made using European Southern ...

With water being so important to life on Earth, scientists often look for it on exoplanets. But some of those worlds might ...

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for ...

New research using NASA's powerful JWST telescope has identified a planet 41 light years away which may have an atmosphere. The planet is within the "habitable zone," the region around a star where ...

On August 24, 2006, our solar system lost a planet. It wasn't by cataclysmic destruction, but rather by the vote of the International Astronomical Union, which declared that Pluto, considered the ...

One of the boldest dreams in modern astronomy is the search for Earth-like worlds beyond our solar system. These exoplanets may hold oceans, rocky ground, and even atmospheres rich in oxygen or ...

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 ...

A low-density, puffy planet orbiting relatively far from a young star in a nearly perpendicular orbit. What's going on?
