The universe is full of billions of galaxies. Why do we see so much structure in the universe today? A 10-year survey of tens of thousands of galaxies has provided a new approach to answering this fundamental mystery.
Astronomers have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known. This finding provides an important clue on how oxygen was produced in the first generations of stars.
Data obtained by VLT showed evidence of massive stars bursts billions of years ago in the galaxy’s center. The more recent burst was so intense that resulted in 100,000 supernova explosions. These findings are inconsistent with our notions that stars formed continuously in our galaxy.
Astronomers have spotted an unusually distant star-forming galaxy, the light of which took a whopping 13 billion years to reach Earth. Perhaps most incredibly, however, the galaxy was observed directly, without gravitational lensing.
An international team of astronomers led by the University of Tokyo used ALMA to view 39 previously-undiscovered ancient galaxies, a find that could have major implications for astronomy and cosmology.
Within 100,000 years of the Big Bang, the very first molecule emerged, an improbable marriage of helium and hydrogen known as a helium hydride ion, or HeH+. It was the beginning of chemistry.
Astronomers from Japan, Taiwan and U.S. have discovered 83 quasars powered by supermassive black holes in the distant universe, from a time when the universe was only 5 percent of its age.
A duo of astronomers has spotted three new globular clusters in the Milky Way’s bulge, a 10,000-light-year-wide central structure made primarily of old stars, gas and dust.
It has taken researchers almost three years to produce this deepest image of the Universe ever taken from space, by recovering a large quantity of ‘lost’ light around the largest galaxies in the iconic Hubble Ultra-Deep Field.
For the first time, researchers have documented the long-predicted occurrence of 'walls bound by strings' in superfluid helium-3. The existence of such an object may explain how the universe cooled down.
A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world's most powerful optical telescope, the W. M. Keck Observatory on Maunakea, Hawaii.
Astronomers have discovered a titanic structure in the early universe, just two billion years after the Big Bang - a galaxy proto-supercluster, nicknamed Hyperion.
Astronomers have observed a galaxy 13.3 billion light years away that includes stars that must have been shining just 250 million years after the Big Bang.
Astronomers from Lancaster University have modeled conditions during the earliest moments of the cosmos.
A small team of researchers announced that its correspondingly small telescope picked up a signal produced by the very first stars in our Universe.
