Three Exoplanets in Habitable Zone of Nearby Star

Three Exoplanets in Habitable Zone of Nearby Star

Astronomers made new observations of Gliese 667C, and by combing them with existing data from HARPS at ESO’s 3.6-metre telescope in Chile, they reveal a system with at least six planets. A record-breaking three of these planets are super-Earths, lying in the Habitable Zone of the star.

La Silla Star Trails North and South

La Silla Observatory in the Atacama desert, Star Trails

Fix your camera to a tripod and you can record graceful trails traced by the stars as planet Earth rotates on its axis. If the tripod is set up at ESO’s La Silla Observatory, high in the Atacama desert of Chile, your star trails would look something like this.  Photographer: Alexandre Santerne

50 New Exoplanets Discovered by HARPS

Exoplanets

Astronomers using ESO’s world-leading exoplanet hunter HARPS have today announced a rich haul of more than 50 new exoplanets, including 16 super-Earths, one of which orbits at the edge of the habitable zone of its star. By studying the properties of all the HARPS planets found so far, the team has found that about 40% of stars similar to the Sun have at least one planet lighter than Saturn.

Starry La Silla

Starry nightThe stars rotate around the southern celestial pole during a night at ESO’s La Silla Observatory in northern Chile. The fuzzy parts in the trails on the right are due to the Magellanic Clouds, two small galaxies neighbouring the Milky Way.  image credit: Iztok Bončina/ESO
