By slamming small particles into heavy gold nuclei at nearly the speed of light, scientists have created tiny, ultra-hot droplets of a bizarre type of matter called a quark-gluon plasma (QGP), which once filled the entire universe shortly after the Big Bang.
Creating such a 'quark soup' is a tough task in its own right; the first sample of QGP was produced less than two decades ago by smashing two heavy atoms together. But for this new study, which was carried out as part of the PHENIX experimen

The dark, high-pressure depths of Earth’s interior is an unexpected place to find life. Now, an international group of scientists report there’s 16.5 to 25 billion tons of micro-organisms beneath the planet’s surface. The team’s work is redefining what a habitable environment is.
The discoveries “force us to reimagine what the boundaries are that life can exist in,” said Karen Lloyd, a microbiologist at the University of Tennessee in Knoxville.

An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth.

The majestic auroras have captivated humans for thousands of years, but their nature -- the fact that the lights are electromagnetic and respond to solar activity -- was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation.

Operation IceBridge, NASA's airborne survey of polar ice, is flying in Greenland for the second time this year, to observe the impact of the summer melt season on the ice sheet. The IceBridge flights, which began on August 27 and will continue until September 16, are mostly repeats of lines that the team flew in early May, so that scientists can observe changes in ice elevation between the spring and late summer.
