Astronomers have uncovered strong evidence that brown dwarfs form like stars.
Using the Smithsonian`s Submillimeter Array (SMA), they detected molecules of carbon monoxide shooting outward from the object known as ISO-Oph 102. Such molecular outflows typically are seen coming from young stars or protostars. However, this object has an estimated mass of 60 Jupiters, meaning it [...]

New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT.
Using computer modeling and a variety of advanced chip-manufacturing techniques, they have applied an antireflection coating to the front, and a novel combination of multi-layered reflective coatings [...]

Astronomers have used light echoes as a time machine to unearth secrets of one of the most influential events in the history of astronomy –a stellar explosion witnessed on Earth more than 400 years ago.
By using a Galactic cloud as interstellar “mirror” an international team led by Oliver Krause of the Max Planck Institute for [...]

In the hit 1998 movie Armageddon, Bruce Willis and Ben Affleck blew up an asteroid to save the world. While the film was science fiction, the chances of an asteroid hitting the Earth one day are very real ― and blowing up an asteroid in real life, says a Tel Aviv University researcher, will be [...]

For the first time, seismic signals that precede a volcanic eruption have been simulated and visualized in 3-D under controlled pressure conditions in a laboratory. The ability to conduct such simulations will better equip municipal authorities in volcanic hot spots around the world in knowing when to alert people who live near volcanoes of an [...]

Imagine a self-powering cell phone that never needs to be charged because it converts sound waves produced by the user into the energy it needs to keep running. It`s not as far-fetched as it may seem thanks to the recent work of Tahir Cagin, a professor in the Artie McFerrin Department of Chemical Engineering at [...]

New rifts have developed on the Wilkins Ice Shelf that could lead to the opening of the ice bridge that has been preventing the ice shelf from disintegrating and breaking away from the Antarctic Peninsula.
The ice bridge connects the Wilkins Ice Shelf to two islands, Charcot and Latady. As seen in the Envisat image above [...]

The remains of a 10-tonne asteroid that exploded in the sky near the Alberta/Saskatchewan border on November 20, 2008 have been located by University of Calgary researchers in a rural area near the city of Lloydminster.
Planetary scientist Dr. Alan Hildebrand and graduate student Ellen Milley located several fragments of meteorite late Thursday afternoon and are [...]

A team of researchers from Arizona State University and the University of Maryland is reporting research that may soon give avid golfers another way to improve their game.
Employing the same sort of scientific approach commonly used to improve the design of automobiles, aircraft, ships, trains, and other moving objects, the team has used a supercomputer [...]
