An inside-out planetary system around the star LHS 1903 is turning everything that astronomers know about planet formation upside down.

Scientists investigating the puzzling, long-lasting, and extreme dimming of a distant star have narrowed the suspects down to either a so-called “failed star” brown dwarf or a truly massive ...

A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

The telescope primarily detects light in the infrared in order to observe sources such as the first galaxies and protostars.

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

Typically, from what astronomers have gathered thus far, star systems follow a tidy logic: small, rocky worlds huddle close to the warmth of their star, while massive gas giants bloat up in the colder ...

The balloon-based EXCITE mission measures infrared phase curves of hot Jupiter exoplanets to map temperature and atmospheric composition from long-duration Antarctic flights.

The James Webb Space Telescope has detected the first-ever spectral signature of hydrogen sulfide around a massive gas giant planet.

ESA’s CHaracterising ExOPlanet Satellite (CHEOPS) has revealed a four-planet system whose outermost world is a small and rocky planet -- not a gas giant.

Surprised astronomers said Thursday they have discovered a star with planets in a bizarre order that defies scientific ...

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover ...
