NASA’s latest planet-hunting probe – the Transiting Exoplanet Survey Satellite (TESS) – has started its search for new worlds around nearby stars, the US Space agency said.

TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth.

The TESS Science Team will begin searching the data for new planets immediately after the first series arrives.

The mission will spend the next two years monitoring the nearest and brightest stars for periodic dips in their light.

These events, called transits, suggest that a planet may be passing in front of its star.

TESS is expected to find thousands of planets using this method, some of which could potentially support life.
