Astronomers have spotted the afterglow of a self-destructing star 13.1 billion light years from Earth.

Wow 600 million years after the big bang? Amazing. This was probably one of the first starts, it's obviously not there anymore, since it took the light to travel billions of years from that locations. Incredible. Must of been a super massive star.

sometimes I don't know should I laugh or not. Inside of the Earth, they guess, black hole, they guess, big bang, they guess, but most of the time they are being presented as facts. But with real testimonies of ghost and ufos, they call you crazy. Funny...

@poplarpublications Pathetic little scumbags always looking to pick a fight and start an argument. Why cant you pigs just accept that others have different beliefs and stop trying to pass off your bullshit as truth. Are you really that selfconscious about your religion that you seek refuge in creating hate and arguments?

@NickMinaj69 Search for "hypervelocity star" and you'll find lots of material. In particular, there'll be a hit on hubblesite for "Hyperfast Star Was Booted from Milky Way" about a star designated HE 0437-5439. You may also be interested in a search for "intergalactic globular cluster" -- entire globular clusters that roam between the galaxies. NGC 2419 *may* be one, in fact (there is some doubt).

@NickMinaj69 You are mostly correct, but not completely. Galaxy collisions can draw out long tidal tails, from which it is possible that individual stars could escape altogether. In addition, it is *known* that stars can be ejected from a galaxy by gravitational interactions near the core; not only is this possible in theory, but we have observations of at least one such runaway star in the Local Group that belongs to no galaxy.

The only starts "not in galaxies" are globular clustarts, which exist in galaxy halo's. Which are in the vicinity of galaxies, but a star just sitting in space, not orbiting a galaxy, is non-existant

Yes I do see what you're saying. It's just that this video claims this to be the most distant object (meaning one object I guess) but doesn't say anything about being in another galaxy. But you may be right.

@bandet888 Not precisely. What I'm saying is that there is probably an agglomeration of stars there (whether it qualifies as a "galaxy" at that young age is a matter of interpretation). What has happened is that a single star in that agglomeration has gone supernova, creating a gamma-ray beam that happened to point in our direction, which we see as a gamma-ray burst. This object is a single star; the whole *galaxy* isn't brighter, just the supernova within it -- the other stars are unchanged.

@bandet888 It's all about brightness. Gamma-ray bursts can, for a short time, be the brightest objects in the entire Universe if you happen to be within the path of the beam. So if a star in a very distant galaxy goes supernova and beams a gamma-ray burst at us, it can be easily visible all the way across the Universe.
