[QUOTE="Channel Hopper, post: 836896, member: 175144"] The British funded observatory in Chile is now up and running. [URL="http://www.almaobservatory.org/"]http://www.almaobservatory.org/[/URL] Already it is confirming that the past universe - at least the light coming from certain sections of it - gave birth to stars at a far greater rate than anyone imagined, and far earlier than predicted. [I]To understand precisely how much this gravitational lensing brightened the view of the galaxies, the team made sharper images of them using more ALMA observations at wavelengths around 0.89 millimeters.[/I] [I]"These beautiful pictures show the background galaxies warped into multiple arcs and rings of light, known as Einstein rings, which encircle the foreground galaxies. It’s like looking through a cosmic kaleidoscope," said Yashar Hezaveh (McGill University, Montreal, Canada), who led the study of the gravitational lensing.[/I] [I]Analysis of the distortion reveals that the distant star-forming galaxies have brightnesses equivalent to as many as 40 trillion (40 thousand billion) Suns, and that gravitational lensing has magnified this by up to 22 times.[/I] The ALMA observatory is some four to ten times as sensitive as the Hubble telescope, so expect some more groundbreaking news in the very near future.
