NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing this data have discovered underlying signals related to seismic waves rippling... Continue reading

After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at... Continue reading

It is extremely difficult to gather information about galaxies at the edge of the Universe: the signals from these heavenly bodies "dilute" in the course of their billion-year journey through space toward earth, making them difficult observational targets. Estimating how... Continue reading

Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists. In... Continue reading

A wealth of moons exist in our own solar system that could host life. Icy Europa, which is circling Jupiter, was recently discovered to have plumes of water erupting from its surface. Titan, in orbit around Saturn, is the only... Continue reading

An international team of physicists has measured a subtle characteristic in the polarization of the cosmic microwave background radiation that will allow them to map the large-scale structure of the universe, determine the masses of neutrinos and perhaps uncover some... Continue reading

Venus is hiding something beneath its brilliant shroud of clouds: a first order mystery about the planet that researchers may be a little closer to solving because of a new re-analysis of twenty-year-old spacecraft data. Venus's surface can't be seen... Continue reading

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have teased out the faint signal of a new organic molecule lurking in interstellar space. The molecule, known as iso-propyl cyanide (i-C3H7CN), is a variant (isomer) of a molecule already... Continue reading

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems,... Continue reading

For years astronomers have searched for the elusive progenitors of hydrogen-deficient stellar explosions without success. However, this changed in June 2013 with the appearance of supernova iPTF13bvn and the subsequent detection of an object at the same location in archival... Continue reading

Using the NASA/ESA Hubble Space Telescope astronomers have made what may be the most reliable distance measurement yet of an object that existed in the Universe’s formative years. The galaxy is one of the faintest, smallest and most distant galaxies... Continue reading

A team led by astronomers from the Max Planck Institute for Astronomy has created the first three-dimensional map of the ‘adolescent’ Universe, just 3 billion years after the Big Bang. This map, built from data collected from the W. M.... Continue reading

The Milky Way Galaxy is actually the largest member of a compact clutch of galaxies that are bound together by gravity. Swarming around our home Galaxy is a menagerie of smaller dwarf galaxies, the smallest of which are the relatively... Continue reading

Space scientists at the University of Leicester have detected a curious signal in the X-ray sky – one that provides a tantalising insight into the nature of mysterious Dark Matter. The Leicester team has found what appears to be a... Continue reading

Our view of other star systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus (Voyager 2 image above). Astronomers have discovered hundreds of planets around the Milky Way,... Continue reading

"We aimed to find the hidden star formation in the Spiderweb cluster (above) — and succeeded — but we unearthed a new mystery in the process; it was not where we expected! The mega city is developing asymmetrically," says Helmut... Continue reading

NASA’s MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet, said University of Colorado Boulder... Continue reading

NASA’s Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon’s volcanic activity slowed gradually instead of stopping abruptly a billion years ago. Scores of distinctive rock deposits observed by LRO are estimated to be less than 100 million... Continue reading

NASA Shares What MAVEN Spacecraft Has Seen in its First Few Weeks at Mars at a news teleconference at today 2 p.m. EDT Tuesday, Oct. 14, to announce early science results from its Mars Atmosphere and Volatile Evolution (MAVEN) mission... Continue reading

Is matter falling into the massive black hole at the center of the Milky Way or being ejected from it? No one knows for sure, but a UC Santa Barbara astrophysicist is searching for an answer. Carl Gwinn, a professor... Continue reading

What is Pluto’s atmosphere like? We’ve known so little for so long about Pluto’s atmosphere – other than it’s low-pressure, made mostly of molecular nitrogen (with a little methane and carbon monoxide mixed in) and may be quite extended –... Continue reading

Scientists examining volcanic deposits on the surface of the planet using NASA’s MESSENGER spacecraft found evidence of explosive activity as recently as a billion years ago. Previous studies of the cratering of other lava flows placed most volcanic activity at... Continue reading

In 2010, scientists discovered that simple peptides can organize into bi-layer membranes. The finding suggests a “missing link” between the pre-biotic Earth’s chemical inventory and the organizational scaffolding essential to life. Many groups studying the origins of life have focused...

NASA's Cassini spacecraft captured this dramatic image of Saturn's geometric jet stream in July 2013 from about 605,000 miles (973,000 kilometers) away from the planet. The image — which NASA released this week provides a close up look at a... Continue reading

NASA hosted a briefing yesterday, Oct. 9, to outline the space and Earth-based assets that will have extraordinary opportunities to image and study Comet C/2013 A1 Siding Spring will miss Mars by only about 88,000 miles (139,500 kilometers). That is... Continue reading
