Primitive asteroids in the main asteroid belt may have formed far from the sun
Many of the objects found today in the asteroid belt located between the orbits of Mars and Jupiter may have formed in the outermost reaches of the solar system. view more (2009-07-16)
Galileo's notebooks may reveal secrets of new planet
Galileo knew he had discovered a new planet in 1613, 234 years before its official discovery date, according to a new theory by a University of Melbourne physicist. view more (2009-07-09)
New definition could further limit habitable zones around distant suns
As astronomers gaze toward nearby planetary systems in search of life, they are focusing their attention on each system's habitable zone, where heat radiated from the star is just right to keep a planet's water in liquid form. view more (2009-06-11)
6.5 million more patients might benefit from statins to prevent heart attacks, strokes
Millions more patients could benefit from taking statins, drugs typically used to prevent heart attacks and strokes, than current prescribing guidelines suggest, Johns Hopkins doctors report in a new study. view more (2009-03-19)
European team finds smallest transiting extrasolar planet ever
The CoRoT satellite has discovered a planet only twice as large as the Earth orbiting a star slightly smaller than the Sun. It is the smallest extrasolar planet (planet outside our solar system) whose radius has ever been measured. view more (2009-02-03)
Helium rains inside jovian planets
Models of how Saturn and Jupiter formed may soon take on a different look. By determining the properties of hydrogen-helium mixtures at the millions of atmospheres of pressure present in the interior of Saturn and Jupiter, physicists at Lawrence Livermore National Laboratory and the University of Illinois at Urbana-Champaign have determined the... view more...

Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL). view more (2008-12-12)
Europa does the wave to generate heat
One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought. view more (2008-12-12)
Astronomers use ultra-sensitive camera to measure size of planet orbiting star
A team of astronomers led by John Johnson of the University of Hawaii's Institute for Astronomy has used a new technique to measure the precise size of a planet around a distant star. They used a camera so sensitive that it could detect the passage of a moth in front of a lit window from a distance of 1,000 miles. view more (2008-12-11)
Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. view more (2008-12-10)
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)
Vitamin C lowers levels of heart disease biomarker, finds study, adds to debate of health benefits
A new study led by researchers at the University of California, Berkeley, adds to the evidence that vitamin C supplements can lower concentrations of C-reactive protein (CRP), a central biomarker of inflammation that has been shown to be a powerful predictor of heart disease and diabetes. view more (2008-11-13)
Researchers discover new risk factor for cardiovascular disease, and a way to control it
A team of international researchers - including scientists from the McGill University Health Centre (MUHC) and McGill University - have discovered that having high levels of particular protein puts patients at increased risk of developing cardiovascular disease. view more (2008-11-10)
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 presence of these three rings of material implies... view more... (2008-10-28)
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)
Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space. view more (2008-09-03)
Jupiter and Saturn full of liquid metal helium
A strange, metal brew lies buried deep within Jupiter and Saturn, according to a new study by researchers at the University of California, Berkeley, and in London. view more (2008-08-07)
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)
