Unique Fragment from Earth’s Formation Returns after Billions of Years in Cold Storage

Unique Fragment from Earth’s Formation Returns after Billions of Years in Cold Storage

Astronomers have found a unique object that appears to be made of inner Solar System material from the time of Earth’s formation, which has been preserved in the Oort Cloud far from the Sun for billions of years. Observations with ESO’s Very Large Telescope, and the Canada France Hawai`i Telescope, show that C/2014 S3 (PANSTARRS) is the first object to be discovered on a long-period cometary orbit that has the characteristics of a pristine inner Solar System asteroid. It may provide important clues about how the Solar System formed.

Four Lasers Over Paranal - First light for the Four Laser Guide Star Facility on ESO’s Very Large Telescope

Four Lasers Over Paranal - First light for the Four Laser Guide Star Facility on ESO’s Very Large Telescope

On 26 April 2016 ESO’s Paranal Observatory in Chile hosted an event to mark the first light for the four powerful lasers that form a crucial part of the adaptive optics systems on ESO’s Very Large Telescope. Attendees were treated to a spectacular display of cutting-edge laser technology against the majestic skies of Paranal. These are the most powerful laser guide stars ever used for astronomy and the event marks the first use of multiple laser guide stars at ESO.
