Interior rotation of a distant star revealed

With the help of asteroseismic data obtained by the CoRoT space telescope, scientists were able to determine the interior rotation of a Sun-like star - and characterise an exoplanet.

To infinity and beyond: teleporting humans into space

In the science fiction show, Star Trek, teleportation is a regular and significant feature. But how much time and power is required to send the data needed to teleport a human being? University of Leicester physics students have calculated the answer to this very question.

Chandra sees eclipsing planet in X-rays for first time

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

Scientists discover surprising importance of 'I Love Q' for understanding neutron stars

Scientists can learn a tremendous amount about neutron stars and quark stars without understanding their internal structure in detail, according to two Montana State University scientists.

Discoveries from Planck may mean rethinking how the universe began

This spring, humanity was shown its most detailed map of the early universe ever created. Generated by observations from the Planck spacecraft, the map revealed fluctuations in temperature in the relic radiation left over from the Big Bang - what we call the Cosmic Microwave Background (CMB). Recently, scientists on the Planck team announced finding certain large-scale features on the CMB sky that they cannot explain. One of them: a large cold spot, which corresponds to an anomalously large area of high density.

Scientists discover massive particle accelerator in heart of Van Allen radiation belts

Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.

IRIS mission gets first look at Sun's mysterious interface region

NASA's Interface Region Imaging Spectrograph (IRIS) spacecraft has captured its first observations of a region of the sun that is now possible to observe in detail: the lowest layers of the sun's atmosphere.

'International beam team' solves Martian meteorite age puzzle (w/video)

By directing energy beams at tiny crystals found in a Martian meteorite, a Western University-led team of geologists has proved that the most common group of meteorites from Mars is almost four billion years younger than many scientists had believed - resolving a long-standing puzzle in Martian science and painting a much clearer picture of the Red Planet's evolution that can now be compared to that of habitable Earth.

Shedding new light on the brightest objects in the universe

Astrophysicists have documented the immense power of quasar radiation, reaching out for many thousands of light years to the limits of the quasar's galaxy.

Solar system's youth gives clues to planet search

Comets and meteorites contain clues to our solar system's earliest days. But some of the findings are puzzle pieces that don't seem to fit well together. A new set of theoretical models from Carnegie's Alan Boss shows how an outburst event in the Sun's formative years could explain some of this disparate evidence. His work could have implications for the hunt for habitable planets outside of our solar system.

Ancient snowfall likely carved Martian valleys

Researchers at Brown University have shown that some Martian valleys appear to have been caused by runoff from orographic precipitation - moisture carried part of the way up a mountain and deposited on the slopes. The findings help to answer the question of whether water flowing on ancient Mars bubbled up from the ground or fell down from the atmosphere.

Spitzer observes gas emission from comet Ison

Astronomers using NASA's Spitzer Space Telescope have observed what most likely are strong carbon dioxide emissions from Comet ISON ahead of its anticipated pass through the inner solar system later this year.

A new record for cosmic X-ray sightings

Scientists led by the University of Leicester have set a new record for cosmic X-ray sources ever sighted - creating an unprecedented cosmic X-ray catalogue that will provide a valuable resource allowing astronomers to explore the extreme Universe.

NASA releases images of Earth by distant spacecraft

Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space.

A warmer planetary haven around cool stars, as ice warms rather than cools

In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star's light with ice and snow on the planet's surface.

Snow in an Infant Solar System - A frosty landmark for planet and comet formation

A snow line has been imaged in a far-off infant solar system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System.
