Some galaxies grew up in a hurry. Most of the galaxies that have been observed from the early days of the universe were young and actively forming stars.
A new study from Tel Aviv University reveals that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. They also imprinted a clear signature in radio waves which astronomers can now search for. The work is a major new finding about the origins of the universe.
Using a telescope in Antarctica and ESA’s Herschel space observatory, astronomers have made the first detection of a subtle twist in the relic radiation from the Big Bang, paving the way towards revealing the first moments of the Universe’s existence.
Scientists using BOSS, the Baryon Oscillation Spectroscopic Survey, have used a new mapping technique to probe the period before dark energy began to speed up the expansion of the universe.
Astronomers have discovered their most distant - and therefore oldest - galaxy yet, using NASA's Spitzer and Hubble space telescopes as well as gravitational lensing.
In an X-ray image looking further into the past than ever before, NASA astronomers have discovered that massive black holes were common in the early universe and grew much more aggressively than previously thought.
Scientists have created the biggest ever 3D map of the distant universe, using the light from 14,000 supermassive black holes, or quasars, at the centers of galaxies billions of light years away.
The first stars in the universe may have spun at over a million miles per hour, astronomers at the Leibniz-Institut für Astrophysik Potsdam (AIP) and the Instituto Nazionale di Astrofisica (INAF) say.
The Planck telescope team has released its first full-sky picture - the clearest yet taken, showing the glow of the first light in the universe.
