The first-ever sighting of an ‘invisible’ black hole could teach us how stars form


Astronomers famously snapped the first ever direct image of a black hole in 2019, thanks to material glowing in its presence. But many black holes are actually near impossible to detect. Now another team using the Hubble Space Telescope seems to have finally found something nobody has seen before: a black hole which is completely invisible. The research, which has been posted online and submitted for publication in the Astrophysical Journal, is yet to be peer-reviewed.

EnVision is set to launch on board an Ariane 6 rocket from Europe’s spaceport in French Guiana in 2031.  “EnVision will answer longstanding open questions about Venus, arguably the… This story continues at The Next Web from The Next Web https://ift.tt/anZTFDP

2024’s most important travel tech trends
