Using an experiment carried into space on a NASA suborbital rocket, astronomers at Caltech and their colleagues have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. Initially some... Continue reading

Using NASA's Chandra X-ray Observatory, astronomers have made the first determination of the mass and other properties of a very young, distant galaxy cluster. The Chandra study shows that the galaxy cluster, seen at the comparatively young age of about... Continue reading

The conditions on Venus are hard to describe. Many planetary scientists say "Start by imagining Hell and work up from there." It's an environment where words like "over 500 degrees Celsius" get thrown around, and it's flat-out crushed every probe... Continue reading

"We are making headway in solving the mystery of Mount Sharp," said Curiosity Project Scientist John Grotzinger of the California Institute of Technology. "Where there's now a mountain, there may have once been a series of lakes." Observations by NASA’s... Continue reading

"Like a phoenix rising from the ashes, Kepler has been reborn and is continuing to make discoveries. Even better, the planet it found is ripe for follow-up studies," says Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics (CfA). The report... Continue reading

A decade ago, astronomers actually thought that the stars within any cluster should all be about the same age, but that idea fell out of favor when clear evidence of the presence of stars of different ages within a single... Continue reading

Nearly 2,000 planets beyond our solar system have been identified to date. Whether any of these exoplanets are hospitable to life depends on a number of criteria. Among these, scientists have thought, is a planet's obliquity the angle of its... Continue reading

A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometres beneath Earth's surface in rock fractures in Precambrian rocks make up over 70% of the surface of the Earth's crust in Canada, South Africa and Scandinavia.... Continue reading

The relationship between Earth's plate tectonics and surface water is one of the great mysteries in the geosciences. But a new study supports researchers’ growing suspicion that mantle convection somehow regulates the amount of water in the oceans. It also... Continue reading

"We think life began on Earth around 3.8 billion years ago, and our result shows that places on Mars had the same conditions at that time – liquid water, a warm environment, and organic matter," said Caroline Freissinet of NASA's... Continue reading

NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill. "This temporary increase in methane --... Continue reading

Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence. In the time following the Big Bang, when the budding universe cooled enough... Continue reading

The carbon in the atmosphere, ocean, surface life, and other shallow, near surface reservoirs accounts for only about 10% of Earth’s carbon. Where is the other 90%? What is it doing? Does it matter? The Deep Carbon Observatory (DCO), an... Continue reading

Our solar system has been voyaging through the very low density Local Interstellar Cloud, a region about 30 light-years across that's as sparse as a handful of air stretched over a column that is hundreds of light years long, or... Continue reading

Astronomers could soon be able to find rocky planets stretched out by the gravity of the stars they orbit, according to a group of researchers in the United States. The team describes how to detect these exotic worlds in a... Continue reading

Astronomers over the decades have been searching for star clusters that could have shared our original region of the galaxy that come close to matching the composition and age of our Sun. The prime suspect so far One is a... Continue reading

“We’re all looking and somewhere, maybe even now, there’s a little bit of data that will cause someone to have an ‘Ah ha!’ moment,” said Harry Nelson, professor of physics at the University of California, Santa Barbara and science lead... Continue reading

For the first time researchers have measured large distances in the Universe using data, rather than calculations related to general relativity. A research team from Imperial College London and the University of Barcelona has used data from astronomical surveys to... Continue reading

Scientists have picked up an atypical photon emission in X-rays coming from space, and say it could be evidence for the existence of a particle of dark matter. The signal comes from a very rare event in the Universe: a... Continue reading

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun. By making detailed observations of the protoplanetary disk surrounding the... Continue reading

Two colossal stars have been discovered that seem to eclipse each other on a daily basis, as they orbit through space. In a paper published in the journal of Astronomy & Astrophysics, Spanish researchers from the Centre of Astrobiology in... Continue reading

Almost immediately after NASA's twin Voyager spacecraft made their brief visits to Saturn in the early 1980s, scientists were hungry for more. The Voyagers had offered them only a brief glimpse of a family of new worlds -- Saturn's icy... Continue reading

Results from the Rosetta mission, which made history by landing on comet 67P in November, an unprecedented, close-up look at a comet is helping scientists to answer the fundamental question of whether a bombardment of these primitive bodies brought water... Continue reading

NASA's "flying saucer" (aka Low-Density Supersonic Decelerator project, or LDSD for short) successfully flew a rocket-powered, saucer-shaped test vehicle into near-space in late June from the U.S. Navy's Pacific Missile Range Facility on Kauai, Hawaii. The goal of this experimental... Continue reading

In his famous lecture on Life in the Universe, Stephen Hawking asks: "What are the chances that we will encounter some alien form of life, as we explore the galaxy?" If the argument about the time scale for the appearance... Continue reading
