Zoom in on the dying star T Leporis

The ESO's Very Large Telescope was used to create an incredible closeup of the star T Leporis, which is dying. This zoom-in starts just south of Orion and winds up on the star, surrounded by a dense shell of material expelled outwards as the star dies.

Hmm, I really don't care about the opinion of some illiterate moron on youtube. I'd sit here, and argue with you, but I just don't have qiute the motivation that you do to start internet arguements.

@ImayStalkU You might have seen something called an "Iridium Flare". Those are satellites that tend to reflect sunlight (400km above the ground, the sun might still reach it) onto the surface of the earth. They can be very bright and last for about three seconds. If yours also moved a little, it definitely was one.

They occur very often almost everywhere on Earth. If you're interested in this, look it up on wikipedia, the article isn't bad.

I've been photographing a star for the last few weeks. It outshines everything in the sky except for the moon. When I zoom in on this object it looks a lot like the dying star shown in this video. It seems to have a core that is surrounded by some sort of gas,or cloud. I'm not sure how to explain it. It almost looks like it's pulsating or throbbing while it spins and creates a strobe-like effect. Could this be a pulsar star,or a star going supernova? Thanks.-V.R

And it must have been Exploding from Red Giant.

@ImayStalkU

You aren't sounding stupid, and what you saw was a Super Nova Explosion, and I think if it disappeared like that then it turned into a black hole, but most likely it was a Super Nova, and it exploded before you even saw it, the light just took quite awhile to reach Earth.

@Mazza4Azza and one more thing.I knew yesterday was meteor shower,so i put the camera shooting.I hope i captured the flash,i will see now.

[SinishaTheScoper]

@Mazza4Azza i know its 2 months old comment but...Yestearday,i was watching a star trough telescope.When i look right,i saw a blue flash,in Cassiopea constellation.When flash was gone,there was something like gray line and gone!Maybe was a fireball or something...

@flowerpotproductions Possibly an Iridium flare? (Google for more info)

@ImayStalkU someone probably just slipped you acid its no big deal

[Djinnhydra]

@ImayStalkU It could have been a star dieing out or it could have been a star becoming a hypergiant either way, it's not good. If a star dies, it either closes in on itself and turns into a black hole, or explodes that makes a massive explosion

Prolly a stupid question but at 0:25 when the pics is getting fuzzy - what would be needed to keep it sharp? Is this just the limitation of the zoom of the lenses used or the end capability of the telescope? Sorry if it stupid question :)

Interesting. I was once in Yorkshire and it was a very clear night. I was lucky to be there to watch a meteor shower. From the corner of my eye I was SURE I saw exactly what you just explained. I doubt it was though - it'd be all over the news.
