ESOcast 71: New Exoplanet-hunting Telescopes on Paranal

14 de Enero de 2015

This ESOcast takes a close look at an unusual new group of small telescopes that has recently achieved first light at ESO’s Paranal Observatory in northern Chile.

The Next-Generation Transit Survey (NGTS) will search for transiting exoplanets — planets that pass in front of their parent star and hence produce a slight dimming of the star’s light that can be detected by sensitive instruments. The telescopes will focus on discovering Neptune-sized and smaller planets, with diameters between two and eight times that of Earth. NGTS is designed to operate in a robotic mode and it will continuously monitor the brightness of hundreds of thousands of comparatively bright stars in the southern skies.

The NGTS discoveries, and follow-up observations by telescopes on the ground and in space, will be important steps in our quest to study the atmospheres and composition of small, Earth-like planets.

More episodes of the ESOcast are also available.
