NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
This artist’s impression shows a view of the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the solar system.
Beyond the outer edge of the Solar System, mysterious, unknown worlds await by the thousands. Astronomers can now finally find them and explore them - but will we find another Earth?
Planets form from a disc of dust orbiting a star.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.
NASA’s Transiting Exoplanet Survey Satellite (TESS) successfully launched on a SpaceX Falcon 9.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
TESS will soon be our eye in the sky.

When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
