A 12.7 Billion Years Old Galaxy Discovered

  More than 12 billion years ago a star exploded, ripping itself apart and blasting its remains outward in twin jets at nearly the speed of light. At its death it glowed so brightly that it outshone its entire galaxy by a million times. This brilliant flash traveled across space for 12.7 billion years to [continue reading]

Cosmic Web of the First Stars Unveiled

  Scientists have discovered a new way to detect the first stars when the Universe was in its infancy at a mere 1% of its present age. The difference between the velocity of dark matter and that of ordinary matter (baryons, i.e., gas consisting of mostly hydrogen and heium). The velocity difference is small in [continue reading]

How the Universe Escaped its 'Dark Ages'

  An international team of astronomers have uncovered an important clue about how the Universe emerged from its ‘dark ages’ some 13 billion years ago. By looking at nearby galaxies, they can infer what may have happened to the first galaxies of our Universe. The large elliptical galaxy NGC1407 is located at the centre of [continue reading]
