At that point we either had found the most distant burst in the universe, or there was dust in the way. |
Dust scatters blue light out, but it's much more gradual. |
Swift detects and localizes and sends the information instantaneously to everybody. Every time a burst goes off, we check the resources we have available. |
This burst smashes the old distance record by 500 million light-years. |
We are finally starting to see the remnants of some of the oldest objects in the universe. |
