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.

How long before we find a planet just like our own?

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.
