Nereidum Montes helps unlock Mars' glacial past
Nereidum Montes helps unlock Mars’ glacial past
On 6 June, the high-resolution stereo camera on ESA's Mars Express revisited the Argyre basin as featured in our October release, but this time aiming at Nereidum Montes, some 380 km northeast of Hooke crater. The stunning rugged terrain of Nereidum Montes marks the far northern extent of Argyre, one of the largest impact basins on Mars.

For the Milky Way, it’s snack time
Yale astronomers have caught the Milky Way having a snack. Using the Sloan Digital Sky Survey, researchers have discovered a band, or stream, of stars believed to be the remnant of an ancient star cluster slowly being ingested by the Milky Way, Earth's home galaxy. "The Milky Way is constantly gobbling up small galaxies and star clusters," said Ana Bonaca, a Yale graduate student and lead author of a study forthcoming in Astrophysical Journal Letters.

Earth’s magnetosphere behaves like a sieve
Earth's magnetosphere behaves like a sieve ESA's quartet of satellites studying Earth's magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed. Earth's magnetic field is our planet's first line of defence against the bombardment of the solar wind.

New understanding of Antarctic’s weight-loss
New data which more accurately measures the rate of ice-melt could help us better understand how Antarctica is changing in the light of global warming.

Radioactive decay of titanium powers supernova remnant
Radioactive decay of titanium powers supernova remnant
Radioactive decay of titanium powers supernova remnant The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA's Integral space observatory. The radioactive decay has likely been powering the glowing remnant around the exploded star for the last 20 years.

Massive Planetary Collision May Have Zapped Key Elements from Moon
A celestial body about the size of the moon slams into a planetary body the size of Mercury in this artist's conception. Credit: NASA/JPL-Caltech Fresh examinations of lunar rocks gathered by Apollo mission astronauts have yielded new insights about the moon's chemical makeup as well as clues about the giant impacts that may have shaped the early beginnings of Earth and the moon.

Keck observations reveal complex face of Uranus
The two faces of Uranus as seen through the adaptive optics on the near-infrared camera of the Keck II telescope in Hawaii. The white features are high altitude clouds like Earth's cumulous clouds, while the bright blue-green features are thinner high-altitude clouds akin to cirrus clouds. Reddish tints indicate deeper cloud layers.

Planet with four stars discovered
Planet with four stars discovered
For the first time a planet has been found that orbits one pair of stars and has a second pair of stars revolving around it - so that four stars illuminate its skies. The discovery was made by volunteers using the planethunters.org website alongside a team led by astronomers from Oxford University, Yale University, and Adler Planetarium.

Solar wind particles likely source of water locked inside lunar soils
Solar wind particles likely source of water locked inside lunar soils
ANN ARBOR-The most likely source of the water locked inside soils on the moon's surface is the constant stream of charged particles from the sun known as the solar wind, a University of Michigan researcher and his colleagues have concluded. Over the last five years, spacecraft observations and new lab measurements of Apollo lunar samples have overturned the long-held belief that the moon is bone-dry.

X-raying stellar winds in a high-speed collision
X-raying stellar winds in a high-speed collision
X-raying stellar winds in a high-speed collision Two massive stars racing in orbit around each other have had their colliding stellar winds X-rayed for the first time, thanks to the combined efforts of ESA's XMM-Newton and NASA's Swift space telescopes. Stellar winds, pushed away from a massive star's surface by its intense light, can have a profound influence on their environment.

Lost asteroid rediscovered with a little help from ESA
Lost asteroid rediscovered with a little help from ESA
Lost asteroid rediscovered with a little help from ESA A potentially hazardous asteroid once found but then lost has been rediscovered and its orbit confirmed by a determined amateur astronomer working with ESA's space hazards programme. The half-kilometre object will not threaten Earth anytime soon.

Nearby super-Earth likely a diamond planet
Nearby super-Earth likely a diamond planet
New research led by Yale University scientists suggests that a rocky planet twice Earth's size orbiting a nearby star is a diamond planet. "This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth," said lead researcher Nikku Madhusudhan, a Yale postdoctoral researcher in physics and astronomy.

Large water reservoirs at the dawn of stellar birth
Large water reservoirs at the dawn of stellar birth
Large water reservoirs at the dawn of stellar birth times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star. Stars form within cold, dark clouds of gas and dust - 'pre-stellar cores' - that contain all the ingredients to make solar systems like our own. Water, essential to life on Earth, has previously been detected outside of our Solar System as gas and ice coated onto tiny dust grains near sites of active star formation, and in proto-planetary discs capable of forming alien planetary systems.

A curious cold layer in the atmosphere of Venus
A curious cold layer in the atmosphere of Venus
A curious cold layer in the atmosphere of Venus Venus Express has spied a surprisingly cold region high in the planet's atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow. The planet Venus is well known for its thick, carbon dioxide atmosphere and oven-hot surface, and as a result is often portrayed as Earth's inhospitable evil twin.

Summer Rain More Likely over Drier Soils
Where does it rain on a hot day's afternoon? New satellite data show that soil moisture plays an important role. It influences precipitation in a way which is quite different from what models have predicted so far. Summer rain is more likely over drier soil - this is the conclusion scientists have drawn from a detailed analysis of satellite data.

Soil Moisture Climate Data Record observed from Space
[ Florian Aigner, Wolfgang Wagner Soil moisture influences our climate. For the first time, long-term data for the whole world is now presented by ESA, the Vienna University of Technology and the Free University of Amsterdam. The future of the world's climate is determined by various parameters, such as the density of clouds or the mass of the Antarctic ice sheet.

Black Holes as Particle Detectors
[ Florian Aigner Previously undiscovered particles could be detected as they accumulate around black holes say Scientists at the Vienna University of Technology. Finding new particles usually requires high energies ' that is why huge accelerators have been built, which can accelerate particles to almost the speed of light.

Oxygen detected in atmosphere of Saturn’s moon Dione
Scientists and an international research team have announced discovery of molecular oxygen ions in the upper-most atmosphere of Dione. Discovery could mean ingredients for life are abundant on icy space bodies Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet.
