A cloud of expanding gas in space is the largest supernova remnant ever seen in the sky, a new study confirms.
The Milky Way has some 300 known supernova remnants, each made of debris from an exploded star mixed with interstellar material swept up by the blast. This supersized one, located in the constellation Antlia, isn’t necessarily the biggest of all physically, but thanks to its proximity to us, it
looks the biggest. As seen from Earth, it spans a region of sky more than 40 times the size of a full moon, astronomer Robert Fesen of Dartmouth College and his colleagues report February 25 at arXiv.org. The Antlia remnant appears about three times as large as the previous champion, the Vela supernova remnant (

Known as comprehensive systems tests, these procedures are meant to ensure that vital systems aboard a craft are fully functional ahead of a launch. The two steps that the telescope successfully passed are tests pertaining to its internal electronic suite, as well as the confirmation that its four scientific instruments can send and receive data properly through the network it will be using in space. The tests took place at Northrop Grumman in collaboration with the Space Telescope Science Institute in Baltimore.
Closer to space
“It’s been amazing to witness the level of expertise, commitment, and collaboration across the team during this important milestone,” said Jennifer Love-Pruitt, Northrop Grumman’s electrical vehicle engineering lead on the Webb observatory. “It’s definitely a proud moment because we demonstrated Webb’s electrical readiness.”
