What happens when a sun dies? :glowing_star:
Astronomers have just captured two real-time stellar explosions—and what they saw was mind-blowing. Using cutting-edge technology, scientists witnessed multiple outflows, delayed ejections, and powerful shockwaves bursting from these dying stars. From sudden blasts to slow eruptions, this is the most detailed look we've ever had at a nova—changing everything we thought we knew about how stars end.

00:00What if I told you scientists just caught a sun exploding, in real time,
00:04and what they saw completely changed what we thought we knew?
00:07Astronomers used the Chera array in California to capture two stellar explosions, called novi,
00:12just days after they erupted.
00:15It's the first time we've seen this level of detail so soon after a star blows up.
00:19They watched as gas burst out from the dying stars.
00:22But it wasn't a simple explosion.
00:25The material flowed out in multiple directions.
00:27Some of it even held back, then burst out later.
00:30That delay was caught on camera for the first time ever.
00:33One of these novi, called viscous tune 74 Hercules, exploded and faded in just days.
00:39It shot out two massive gas streams at right angles.
00:42When they collided, NASA's Fermi telescope detected intense gamma rays.
00:46The second, V1405 Cassiopeia, exploded slowly.
00:50It took over 50 days to finally release its outer layers.
00:54But when it did, boom, another gamma ray blast.
00:58Using a technique called interferometry, scientists created sharp images,
01:02revealing shock waves, gas structures, and hidden flows never seen before.
01:07These aren't just cosmic fireworks.
01:09They're live experiments in space.
01:11And now, for the first time, we're watching the drama unfold, frame by frame.
01:16The last thing is, the reality has changed in mind.
01:19It wentyましょう.
01:21I, it don't turn on, the waves tries to consciousness.
01:22It playednotica, but it turns out at the least, 351 margins imagine the door coming in.
01:27So if we try toino.
01:32The monsterист could be open before the bumps used, all the interference, and the meteorites.
