Just below the surface of Mars, scientists suspect that there might be briny waters that, according to a new study, could hold enough molecular oxygen to support certain types of life. As light breaks down carbon dioxide on Mars, a little bit of oxygen is produced. Previously, it has been thought that the minuscule amount of molecular oxygen on Mars could not be enough to support even microscopic life on the Red Planet. However, if there are briny waters just below the planet’s surface, t

Io, Enceladus, Earth — our solar system holds a number of locations where plumes of gas erupt. And for years, scientists have suspected that such plumes also exist on Jupiter’s moon Europa. However, according to one new study done using decades-old data from NASA’s Galileo mission, two potential plume sites on the world lack the hot spot signatures that are typically associated with plumes. “We searched through the available Galileo thermal data at the locations proposed

The Big Bang, as many cosmologists like to point out, was not very banging. Nothing exploded. But that doesn’t mean it wasn’t a busy and exciting event. The rush of inflation was a powerful outpouring of energy, which certainly included light. And yet, the energy contained in that early universe was such that light couldn’t even escape. For light to be seen, by telescopes or eyes of any species, it needs to be able to travel from its source to the observer. But the universe whe

In a move that would have seemed unthinkable two years ago, President Trump offered a full embrace, literally and figuratively, of Ted Cruz in a massive rally here Monday night, imploring a crowd of tens of thousands of supporters to turn out for his former political rival in a closely watched Senate race in Texas.

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. read more

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. read more

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.) read more

Terzan 5, 19 000 light-years from Earth in the constellation of Sagittarius (the Archer) and in the direction of the galactic centre, has been classified as a globular cluster for the forty-odd years since its detection. Now, an Italian-led team of astronomers have discovered that Terzan 5 is like no other globular cluster known. read more

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. read more

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. read more

Pluto is still not a planet, but it does boast an impressive entourage. Astronomers said Wednesday that they had spotted a fifth moon orbiting Pluto, which they already knew had four. The discovery, made with the Hubble Space Telescope, gives Pluto more moons than Mercury, Venus, Earth and Mars combined.

Galaxy clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars. It has long been known that when a galaxy falls into a cluster, star formation is fairly rapidly shut off in a process known as 'quenching.' A new study has made the best measurement yet of the quenching timescale, measuring how it varies across 70 percent of the history of the universe.

New research, published today in the journal Monthly Notices of the Royal Astronomical Society, has found evidence for a large number of double supermassive black holes, likely precursors of gigantic black hole merging events. This confirms the current understanding of cosmological evolution—that galaxies and their associated black holes merge over time, forming bigger and bigger galaxies and black holes.
