A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK’s WASP project in ...

In a significant leap forward in the quest for extraterrestrial life, NASA recently announced the detection of oxygen in the atmosphere of an exoplanet. This revolutionary discovery will be the ...

Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the first confirmed discovery in the 1990s, more than 5,000 have been identified, ...

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 ...

It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...

An international team of astronomers reports the discovery of a new giant exoplanet around an M-dwarf star (GEMS). The newfound GEMS, designated TOI-5573 b, is comparable in size to Saturn and its ...

Astronomers have spotted a monster-sized planet that could be up to ten times the size of Jupiter emerging from the stellar fog surrounding a young star. Prior observations of the roughly 13 ...

Most exoplanet hunters chase biosignatures the way bird dogs chase the scent of a quail. But in a talk at the European Astrobiology Institute’s recent BEACON 25 conference in Reykjavik, astrophysicist ...

Astronomers have narrowed down the cosmic search for life, identifying fewer than 50 rocky planets among thousands of known exoplanets that may have the right conditions to support life. Using new ...

More than 6,000 exoplanets, or worlds beyond our solar system, have so far been confirmed. The new technique involved analyzing old data from NASA's TESS satellite, focusing on fainter stars. Finding ...
