The Beginnings of our Universe? Hubble telescope does it again
The Hubble Telescope has done it again! This time it has located a number of galaxies that are the oldest ever observed by humankind. These galaxies are thought to have formed somewhere between 350 and 600 million years after the Big Bang which formed our universe. This article from Astronomy magazine gives us the details.
Using NASA’s Hubble Space Telescope, astronomers announced December 12 that they have seen further back in time than ever before and have uncovered a previously unseen population of seven primitive galaxies that formed more than 13 billion years ago when the universe was less than 3 percent of its present age. The deepest images to date from Hubble yield the first statistically robust sample of galaxies that tells how abundant they were close to the era when galaxies first formed.
The results are from an ambitious Hubble survey of an intensively studied patch of sky known as the Ultra Deep Field (UDF). In the 2012 campaign, called UDF12, a team of astronomers led by Richard Ellis of the California Institute of Technology in Pasadena used Hubble’s Wide Field Camera 3 (WFC 3) to peer deeper into space in near-infrared light than any previous Hubble observation.
