Because the burst was brighter than a billion suns, many telescopes could study it even from such a huge distance. |
He rode his bike (to campus) every day. It never mattered what the weather was. He would only drive if the weather was really bad. |
I think this is a temporary distance record that will be broken some time in the near future. |
Soon, we expect that Swift will find bursts that are even farther back in time than this explosion -- more distant than any object ever observed. We are in the process of pushing back the boundaries of the observable universe. |
Stars are exploding two, three, and sometimes four times in the first minutes following the initial explosion, ... First comes a blast of gamma-rays followed by intense pulses of X-rays. The energies involved are much greater than anyone expected. |
That's Oceans Digital TV- it's allowing our subscribers to immerse themselves in the type of quality television they want without having to go abroad to get it. |
The jet looks like steam from a high pressure boiler, except when you realize you are looking at a stream of matter and antimatter electrons moving at half the speed of light. |

This was a massive star that lived fast and died young. |
This was a massive star that lived fast and died young. This star was probably quite different from the kind we see today, the type that only could have existed in the early universe. |
What we had seen primarily in the past was we'd have a bright flash of high-energy radiation and then it would just fade away gradually, |
