The wonders of life on Earth are endless, but all that may never have come to pass were it not for the planet having the perfect amount of oxygen at birth.

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.

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

"This strange disorder makes it a unique inside-out system," study lead author Thomas Wilson, physics professor from the University of Warwick, said in a statement. "Rocky planets don't usually form ...

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

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 ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...

A rocky exoplanet in the LHS 1903 system defies planet formation models, hinting that gravitational upheaval reshaped the red ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.
