“Earth’s Double Asteroid Flyby” — An ‘Apocalypse Drill’ With ESO’s Exoplanet Observer

“The double asteroid was hurtling by the Earth at more than 70 000 km/h, making observing it with the Very Large Telescope (VLT ) challenging,” said Diego Parraguez, who was piloting the European Southern Observatory telescope. He had to use all his expertise to lock on to the fast asteroid and capture it with SPHERE, one of the very few instruments in the world capable of obtaining images sharp enough to distinguish the two components of the asteroid, which are separated by around 2.6 km.

First light at four telescopes devoted to the search for habitable planets around nearby ultra-cool stars got off to a successful start at ESO’s Paranal Observatory. “These new telescopes will allow us to investigate nearby Earth-like worlds in the universe in greater detail than we could have imagined only ten years ago,” said Michaël Gillon of the University of Liège. “These are tremendously exciting times for exoplanet science.”
