Cosmic explosion in the early Universe

The afterglow from this exploding star
did not show itself as visible light -
this picture from the Swift satellite
shows the afterglow in the x-ray band.

After traveling through the Universe for more than 13 billion years, light from an exploding star has reached earth.

A team of researchers, led by Dark Cosmology Centre (DARK) associate scientist Nial Tanvir (University of Leicester) and including 6 members of the DARK staff, has detected and analyzed a gamma-ray burst at a redshift of z approximately 8.2.

You can read more about how this light has been detected and what it means for our understanding of the Universe here (in Danish at videnskab.dk).

You can read the team's article in Nature here, see their video on the discovery, and find further information here.
