The color of the table row gives a rough interpretation of the severity of the threat.
Small objects are not likely to cause significant damage in the event of an impact, although impact damage does depend heavily upon the specific (and usually unknown) physical properties of the object in question.
Barcons begins his tenure at an exciting time for ESO.
Construction of the Extremely Large Telescope is progressing rapidly and it is set to see first light in 2024.
Whenever a potential impact is detected it will be analyzed and the results immediately published here, except in unusual cases where we seek independent confirmation.Observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) and ESA’s Rosetta mission, have revealed the presence of the organohalogen Freon-40 in gas around both an infant star and a comet.Organohalogens are formed by organic processes on Earth, but this is the first ever detection of them in interstellar space.Countless galaxies vie for attention in this monster image of the Fornax Galaxy Cluster, some appearing only as pinpricks of light while others dominate the foreground. The turbulent past of this much-studied galaxy has left it with a delicate structure of loops, arcs and rings that astronomers have now imaged in greater detail than ever before with the VLT Survey Telescope.This astonishingly deep image also reveals a myriad of dim objects along with faint intracluster light.
