First exoplanet visible light spectrum

Astronomers using the HARPS planet-hunting machine at ESO's La Silla Observatory in Chile have made the first-ever direct detection of the spectrum of visible light reflected off an exoplanet. These observations also revealed ...

NASA asks: Will we know life when we see it?

In the last decade, we have discovered thousands of planets outside our solar system and have learned that rocky, temperate worlds are numerous in our galaxy. The next step will involve asking even bigger questions. Could ...

ESO signs contracts for the ELT's gigantic primary mirror

The unique optical system of ESO's Extremely Large Telescope consists of five mirrors, each of which represents its own significant engineering challenge. The 39-metre-diameter primary mirror, which will be made up of 798 ...

First light for ESPRESSO—the next generation planet hunter

The Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations (ESPRESSO) has successfully made its first observations. Installed on ESO's Very Large Telescope (VLT) in Chile, ESPRESSO will search for ...

VLT revisits a curious cosmic collision

The spectacular aftermath of a 360 million year old cosmic collision is revealed in great detail in new images from ESO's Very Large Telescope at the Paranal Observatory. Among the debris is a rare and mysterious young dwarf ...

Robot would assemble modular telescope—in space

Enhancing astronomers' ability to peer ever more deeply into the cosmos may hinge on developing larger space-based telescopes. A new concept in space telescope design makes use of a modular structure and an assembly robot ...
