Ka-PLOWee!

On March 19, there was a tremendous explosion in outer space. The massive gamma-ray burst was faintly visible to the naked eye, despite being 7.5 billion light years away. That’s half the distance across the Universe, and 1,000 times further than the previous record for most distant visible object. Gamma-ray bursts occur when giant stars run out of fuel and collapse, releasing huge amounts of energy.

Why was there an explosion in outer space?

how long would it have taken the light from the explosion to reach our planet from that distance?

Seven and a half billion years. In other words, the star exploded and emitted gamma rays some three billion years before the Earth was even formed!

it exploded because thats what happens when the stars run out of energy. i mean when your over tired and someone says something to you that sets you off u explode right.

Ha ha! ;-) But not quite. Stars burn by fusing light elements together to form heavier elements, releasing energy. Eventually, they end up with elements too heavy to fuse. At that point, the star collapses in on itself, and the force of the colliding matter causes the explosion.

Earth -- no. Sun -- yes. Right now, the Sun fuses hydrogen atoms into helium. In another 4 or 5 billion years, it will run out of hydrogen, and will start fusing helium together. This releases more energy, and the Sun will expand in size, engulfing the Earth and the other inner planets. Beyond that, I'm not sure, but I don't think the Sun is big enough to fuse much heavier elements. The Sun will eventually run out of fuel and collapse, but the explosion won't be this big. We'll all be long gone, anyway.

how can an explosion that far away be seen from earth? also about how long would it take for en explotion that big to reach us?

what happen if its to close to earth...

Gamma rays are extremely high-energy light wave. Depending on how close to Earth the star is, it could basically kill most life on the planet.

The effect of gamma rays on Earthly life forms can be deadly. The Effect of Gamma Rays on Man-in-the-Moon Marigolds is much more abstract. ;-)
