💥💥 Double detonation! For the first time, astronomers have obtained visual evidence that a star met its end by blasting twice. This was done by studying the centuries-old remains of supernova SNR 0509-67.5 with our Very Large Telescope. Led by the Univ. of South Wales, this shows some of the most important explosions in the Universe in a new light. What happened exactly?

New instance, new #introduction ! Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes. One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons! We’re looking forward to chatting with all of you about #astronomy And many thanks to @npub1hece...saxk for running our former instance! 📷 ESO/G. Vecchia
