Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.

By comparing teeth from two species of early humans, Australopithecus africanus and Paranthropus robustus, the researchers confirm previous evidence that A. african

MARSIS, the sounding radar on board ESA’s Mars Express spacecraft, is collecting the first data about the surface and the ionosphere of Mars.

The radar started its science operations on 4 July 2005, after the first phase of its commissioning was concluded on the same day. Due to the late deployment of MARSIS, it was decided to split the commissioning, originally planned to last four weeks, into two phases, one of which has just ended and the second one to be started by December th

New images of Saturn obtained by a University of Colorado at Boulder-led team on June 21 using an instrument on the Cassini spacecraft show auroral emissions at its poles similar to Earth’s Northern Lights.

Taken with the Ultraviolet Imaging Spectrograph aboard the Cassini orbiter, the two UV images, invisible to the human eye, are the first from the Cassini-Huygens mission to capture the entire “oval” of the auroral emissions at Saturn’s south pole. They also show similar emissio

The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings.

In a significant breakthrough, researchers at Northwestern University’s Center for Quantum Devices have demonstrated a specialized diode laser that holds promise as a weapon of defense in both civilian and military applications. Once optimized, the tiny laser could quickly detect explosives and CWAs early and warn agai

On its recent close flyby of Mimas (MY-muss), the Cassini spacecraft found the Saturnian moon looking battered and bruised, with a surface that may be the most heavily cratered in the Saturn system.

The Aug. 2 flyby of Saturn’s ’Death Star’ moon returned eye-catching images of its most distinctive feature, the spectacular 140-kilometer diameter (87-mile) landslide-filled Hershel crater. Numerous rounded and worn-out craters, craters within other craters and long grooves reminiscent of

In two days’ time [Wednesday 10th August] NASA will launch the biggest spacecraft ever to be sent to Mars – Mars Reconnaissance Orbiter (MRO). UK scientists are involved with MRO’s Mars Climate Sounder instrument that will profile the atmosphere of Mars. Additionally, MRO carries high resolution cameras to provide the most detailed picture yet of the Red Planet’s surface, including the potential to trace lost Mars missions such as the UK’s Beagle 2.

ESA’s Venus Express spacecraft has just completed its last phase of testing in Europe and is ready to be shipped to its launch site at the Baikonur Cosmodrome in Kazakhstan.

One and a half years after its sister spacecraft Mars Express arrived at Mars, Europe’s newest planetary probe is ready to depart on the first leg of its journey to Earth’s own sister planet, the mysterious Venus.

Venus Express was proposed in 2001, as a mission concept to take as much as possible

Why does the sky glow?

Astronomers have found that the sky glows in very energetic X-rays. They think the X-rays are the last gasp of material being swallowed by massive black holes. These objects hide behind thick walls of gas and dust, walls so thick that only radio waves and very high-energy X-rays can escape. Even moderately energetic X-rays are blocked.

When astronomers find massive black holes swallowing their surroundings, they can identify them by their peculiar
