‘Teen galaxies’ are discovered
From Times Staff and Wire Reports
Young galaxies, so faint that scientists struggled to prove they were there, have been discovered by aiming two of the world’s most powerful telescopes at a single patch of sky for nearly 100 hours.
An international research team has identified 27 pre-galactic fragments, “teenager galaxies,” which they hope will help astronomers understand how our own Milky Way reached adulthood.
The telescopes allowed scientists to see back 11 billion years or more, to 2 billion years after the Big Bang. The clusters make a compelling case for the theory that galaxies formed bit by bit instead of all at once, cosmologists said.
