Dawn reveals complexities of ancient asteroidal world
New findings from NASA's Dawn spacecraft lay the groundwork for the first geological overview of asteroid (4)Vesta and confirm the existence of not one but two giant impact basins in its southern hemisphere. View More (2012-05-11)
You're beautiful, Vesta
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks about science. View More (2012-05-11)
IBEX Reveals a Missing Boundary At the Edge Of the Solar System
For the last few decades, space scientists have generally accepted that the bubble of gas and magnetic fields generated by the sun - known as the heliosphere - moves through space, creating three distinct boundary layers that culminate in an outermost bow shock. View More (2012-05-11)
UF astronomer: Some giant planets in other systems most likely to be alone

Climatic effects of a solar minimum
An abrupt cooling in Europe together with an increase in humidity and particularly in windiness coincided with a sustained reduction in solar activity 2800 years ago. Scientists from the German Research Centre for Geosciences GFZ in collaboration with Swedish and Dutch colleagues provide evidence for a direct solar-climate linkage on centennial timescales.

Four white dwarf stars caught in the act of consuming 'earth-like' exoplanets
University of Warwick astrophysicists have pinpointed four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth. View More (2012-05-04)
Science nugget: Lightning signature could help reveal the solar system's origins
Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere. View More (2012-05-04)
'Faster-ticking clock' indicates early solar system may have evolved faster than we think
Our solar system is four and a half billion years old, but its formation may have occurred over a shorter period of time than we previously thought, says an international team of researchers from the Hebrew University of Jerusalem and universities and laboratories in the US and Japan.

Clean Drinking Water for Everyone
Nearly 80 percent of disease in developing countries is linked to bad water and sanitation. Now a scientist at Michigan Technological University has developed a simple, cheap way to make water safe to drink, even if it's muddy. View More (2012-05-02)
Venus to appear in once-in-a-lifetime event
On 5 and 6 June this year, millions of people around the world will be able to see Venus pass across the face of the Sun in what will be a once-in-a-lifetime experience. View More (2012-05-01)
Folding light: Wrinkles and twists boost power from solar panels

New graphene-based material could revolutionize electronics industry
The most transparent, lightweight and flexible material ever for conducting electricity has been invented by a team from the University of Exeter. Called GraphExeter, the material could revolutionise the creation of wearable electronic devices, such as clothing containing computers, phones and MP3 players. View More (2012-04-30)
Record-Breaking Radio Waves from Ultra-Cool Star
Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous record for the lowest stellar temperature at which radio waves were detected.
