Galaxies in the early universe mature beyond their years

Posted: 10 Mar 2014 06:39 PM PDT

An international team of researchers has discovered the most distant examples of galaxies in the early universe that were already mature and massive. The mature galaxies were found at a record-breaking distance of 12 billion light years, seen when the universe was just 1.6 billion years old. Their existence at such an early time raises new questions about what forced them to grow up so quickly.

Possible evidence for dark matter particle presented at UCLA physics symposium

Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation. At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that participants interpreted to imply the existence of a dark matter particle. The likely mass would be approximately 30 billion electron-volts, said the symposium's organizer.
