Cosmic Log - Scientists pinpoint the farthest galaxy
The galaxy, known as UDFy-38135539, is one of several super-distant objects picked out from the Hubble Ultra Deep Field, the most sensitive snapshot ever taken of deep space. In time, astronomers may well spot objects that are even farther away, but this particular galaxy was the first of its type to go through the arduous process of having its measurements checked.
In fact, the astronomers behind the observations say they couldn’t have seen UDFy-38135539 unless there were other, fainter galaxies nearby to help clear out the space around it. “Without this additional help, the light from the galaxy, no matter how brilliant, would have been trapped in the surrounding hydrogen fog, and we would not have been able to detect it,” Durham University’s Mark Swinbank said in a news releasefrom the European Southern Observatory.
