At that point we either had found the most distant burst in the universe, or there was dust in the way.

This burst smashes the old distance record by 500 million light-years.

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.

We are finally starting to see the remnants of some of the oldest objects in the universe.

You either make dust or eat dust.
