MUSE observations enable prediction of once-in-a-lifetime supernova replay
Munich, Germany (SPX) Nov 27, 2015
Astronomers have used the Multi Unit Spectroscopic Explorer (MUSE), attached to ESO's Very Large Telescope (VLT) at the Paranal Observatory, to take advantage of a once-in-a-lifetime opportunity to test their understanding of massive clusters of galaxies. They are making the first ever prediction of an observational event in the distant Universe before it actually becomes visible. Images of the galaxy cluster MACS J1149+2223, taken by the NASA/ESA Hubble Space Telescope in November 2014, revealed ... read more
