Jupiter's rocky core bigger and icier, model predicts
Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms.   view more (2008-11-26)

Beta Pictoris planet finally imaged?
A team of French astronomers using ESO's Very Large Telescope have discovered an object located very close to the star Beta Pictoris, and which apparently lies inside its disc.   view more (2008-11-24)

UBC researchers develop breakthrough technique to unlock the secret of plasmas
University of British Columbia researchers have developed a technique that brings scientists a big step closer to unlocking the secrets of the most abundant form of matter in the universe.   view more (2008-11-24)

Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun.   view more (2008-11-19)

Very cold ice films in laboratory reveal mysteries of universe
The universe is full of water, mostly in the form of very cold ice films deposited on interstellar dust particles, but until recently little was known about the detailed small scale structure.   view more (2008-11-06)

Chandrayaan-1 now in lunar transfer trajectory
Yesterday, following a fifth orbit-raising manoeuvre, the Chandrayaan-1 spacecraft successfully settled into a trajectory that will take it to the Moon.   view more (2008-11-06)

MIT researchers find clues to planets' birth
Meteorites that are among the oldest rocks ever found have provided new clues about the conditions that existed at the beginning of the solar system, solving a longstanding mystery and overturning some accepted ideas about the way planets form.   view more (2008-10-31)

Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the... view more (2008-10-28)

21st century detective work reveals how ancient rock got off to a hot start
A new technique using X-rays has enabled scientists to play 'detective' and solve the debate about the origins of a three billion year old rock fragment.   view more (2008-10-16)

MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton.   view more (2008-10-16)

NASA Supercomputer Shows How Dust Rings Point to Exo-Earths
Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets.   view more (2008-10-13)

Field Museum provides gold standard for mammal survey
Putting together the Who's Who of bats, bears, beaked whales and all of Earth's other known mammals was a gigantic task ably assisted by a Field Museum scientific team with access to one of the planet's most extensive and diverse mammal collections.   view more (2008-10-07)

Next-generation adaptive optics produces sharper Jupiter images
A two-hour observation of Jupiter using an improved technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground, according to astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO).   view more (2008-10-03)

CU-Boulder space scientists set for second spacecraft flyby of Mercury
NASA's MESSENGER spacecraft, which is toting an $8.7 million University of Colorado at Boulder instrument to measure Mercury's wispy atmosphere and blistering surface, will make its second flyby of the mysterious, rocky planet Oct. 6.   view more (2008-10-01)

100 million years AD
Jan Zalasiewicz, a lecturer in geology at the University of Leicester, has published a new study looking at the lasting impression made by mankind -100 million years hence.   view more (2008-09-26)

McGill researchers find oldest rocks on Earth
McGill University researchers have discovered the oldest rocks on Earth - a discovery which sheds more light on our planet's mysterious beginnings.   view more (2008-09-26)

Melting ice under pressure
The deep interior of Neptune, Uranus and Earth may contain some solid ice. Through first-principle molecular dynamics simulations, Lawrence Livermore National Laboratory scientists, together with University of California, Davis collaborators, used a two-phase approach to determine the melting... view more (2008-09-24)

GOCE Earth Explorer satellite to look at the Earth's surface and core
The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earth's gravitational field and to map the reference shape of our planet - the geoid - with unprecedented resolution and accuracy.   view more (2008-08-25)

Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.   view more (2008-08-25)

Actions of individuals key to saving biodiversity-and ourselves, Stanford biologists say
Even if you don't like the outdoors, you're probably pretty fond of air, clean water and food. That makes you a fan of biodiversity, because those essentials for life-human and otherwise-are maintained as a direct result of the Earth's biodiversity, the abundance and variety of species and... view more (2008-08-12)

Universally Speaking, Earthlings Share a Nice Neighborhood
We don't have spacecraft to take us outside our solar system--not yet, at least. Still, astronomers thought they had a pretty good understanding of how our solar system formed and in turn, how others formed.   view more (2008-08-11)

COROT finds exoplanet orbiting Sun-like star
A team of European scientists working with COROT have discovered an exoplanet orbiting a star slightly more massive than the Sun. After just 555 days in orbit, the mission has now observed more than 50 000 stars and is adding significantly to our knowledge of the fundamental workings of stars.   view more (2008-07-28)

Brown papers reveal widespread, hardworking water on ancient Mars
For decades, scientists have theorized - romanticized, even - that Mars has harbored water. The evidence has grown stronger as recent missions to the Red Planet have revealed in stunning detail Martian topography, mineralogy and clues to past climate. But how much water, where it was or is located... view more (2008-07-17)

Surprisingly rapid changes in the Earth's core discovered
In a recent paper published in Nature Geoscience, the geophysicist Mioara MANDEA from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth's core are changing... view more (2008-07-08)

Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system.   view more (2008-07-07)
