«The galaxy we have observed, EGS8p7, which is unusually luminous, may be powered by a population of unusually hot stars, and it may have special properties that enabled it to create a large bubble of ionized hydrogen much earlier than is possible for more typical galaxies at these times,» Sirio Belli, a Caltech graduate student who worked on the project, said, in the statement.

As well as keeping an eye out for solar flares, it will also be looking well past the Sun to gain a better grasp of the earliest, most distant galaxies we have ever observed to give astronomers a better idea of what happened in the very early days of our Universe, and perhaps shed light on how the relationship between gravity and dark matter evolved.

Although GRB 000131, like other gamma - ray bursts, appears to have taken place in a remote «early galaxy» (or «sub-galactic clumps» of stars) that is smaller than today's luminous galaxies, astronomers found it difficult to detect that extremely dim, sub-galactic clump of stars even with the Hubble Space Telescope, as the observed fading of the afterglow indicated that the maximum brightness of the gamma - ray emission was explosion was at least 10,000 times brighter than its host galaxy.
Because the elements that we observe in our stars today were made prior to the stars» birth — the stars inherited these heavy elements like «cosmic genes» — we have this incredible opportunity to look back in time to study the early chemical and physical processes that ushered in stars and galaxy formation soon after the Big Bang.
But we haven't fully connected our theories to what we observe, especially with quasars, these incredibly bright centers of very distant galaxies that serve as beacons of the early universe.
