New measurements from some of the most distant galaxies bolster the evidence that the strongest burst of star formation in the history of the Universe occurred about two billion years after the Big Bang. An international team of astronomers from the UK, France, Germany and the USA have found evidence for a dramatic surge in star birth in a newly discovered population of massive galaxies in the early Universe.In his talk at the RAS National Astronomy Meeting in Belfast on Tuesday 1 April, team...

NEW BRUNSWICK, N.J. "“ Astronomers at Rutgers and Penn State universities have discovered galaxies in the distant universe that are ancestors of spiral galaxies like our Milky Way. These ancient objects, some of the first galaxies ever to form, are being observed as they looked when the universe was a mere two billion years old. Today, scientists peg the universe's age at 13.7 billion years, so light from these galaxies traveled almost 12 billion years to reach Earth. The newly...

NASA's Hubble and Spitzer Space Telescopes have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a hundred to a thousand times smaller than our Milky Way Galaxy. "These are among the lowest mass galaxies ever directly observed in the early universe" says Nor Pirzkal of the Space Telescope Science Institute in Baltimore, Md. The...

Cambridge, MA -- By combining the capabilities of several telescopes, astronomers have spotted extremely bright galaxies hiding in the distant, young universe. The newfound galaxies are intrinsically bright due to their large rate of star formation-1000 times greater than the Milky Way. However, much of that light is hidden by surrounding dust and gas, leaking out only in the infrared. The galaxies are located about 12 billion light-years away, and existed when the universe was less than 2...

Several hundred images taken with NASA's Hubble Space Telescope have been woven together into a rich tapestry of at least 50,000 galaxies. The Hubble view is yielding new clues about the universe's youth, from its "pre-teen" years to young adulthood. The snowstorm of galaxies in the Hubble panorama does not appear evenly spread out. Some galaxies seem to be grouped together. Others are scattered through space. This uneven distribution of galaxies traces the concentration of dark matter, an...

Astronomers analyzing two of the deepest views of the cosmos made with NASA's Hubble Space Telescope have uncovered a gold mine of galaxies, more than 500 that existed less than a billion years after the Big Bang. These galaxies thrived when the cosmos was less than 7 percent of its present age of 13.7 billion years. This sample represents the most comprehensive compilation of galaxies in the early universe, researchers said. The discovery is scientifically invaluable for understanding the...

A systematic search for the first bright galaxies to form in the early universe has revealed a dramatic jump in the number of such galaxies around 13 billion years ago. These observations of the earliest stages in the evolution of galaxies provide new evidence for the hierarchical theory of galaxy formation -- the idea that large galaxies built up over time as smaller galaxies collided and merged. Astronomers at the University of California, Santa Cruz, used NASA's Hubble Space Telescope to...

Rare Blob Unveiled: Evidence for Hydrogen Gas Falling onto a Dark Matter Clump? ESO's VLT has helped scientists to discover a large primordial 'blob', more than 10 billion light-years away. The most likely scenario to account for its existence and properties is that it represents the early stage in the formation of a galaxy, when gas falls onto a large clump of dark matter. Over the last few years, astronomers have discovered in the distant Universe a few so-called 'blobs'. These are rather...

NASA -- An analysis of the Hubble Space Telescope's deepest view of the universe offers compelling evidence that monster black holes in the centers of galaxies were not born big but grew over time through repeated galactic mergers. "By studying distant galaxies in the Hubble Ultra Deep Field (HUDF), we have the first statistical evidence that supermassive black-hole growth is linked to the process of galaxy assembly," said astronomer Rogier Windhorst, of Arizona State University in Tempe,...

More than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years, according to a Yale astronomer in a study using hundreds of images from two of the deepest sky surveys ever conducted. The idea of large galaxies being assembled primarily by mergers rather than evolving by themselves in isolation has grown to dominate cosmological thinking. However, a troubling inconsistency within this general theory has been that the...
