Avoiding stumbles, from spacewalks to sidewalks

more »
Researchers are developing a new space boot with built-in sensors and tiny 'haptic' motors, whose vibrations can guide the wearer around or over obstacles. A preliminary study was designed to determine what types of stimuli, administered to what parts of the foot, could provide the best navigation cues.

Transformations to granular zircon revealed: Meteor Crater, Arizona

more »
Having been reported in lunar samples returned by Apollo astronauts, meteorites, impact glass, and at a number of meteorite craters on Earth, granular zircon is the most unusual and enigmatic type of zircon known. The mechanisms and transformations that form this distinctive granular zircon have, until now, remained speculative because it has not been produced in shock experiments.

Scientists simulated a nuclear explosion of an asteroid

more »
Scientists are developing measures to protect the Earth from potentially dangerous celestial bodies. With the help of supercomputer SKIF Cyberia, the scientists simulated the nuclear explosion of an asteroid 200 meters in diameter in such a way that its irradiated fragments do not fall to the Earth.

White dwarf lashes red dwarf with mystery ray

more »
Astronomers have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star is powering electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.

Finding the loneliest young star

more »
Alone on the cosmic road, far from any known celestial object, a young, independent star is going through a tremendous growth spurt. When a team of scientists examined infrared images of the same area, they realized this object has a lot of warm dust around it, which must have been heated by an outburst. Researchers determined it likely is a young star that has been outbursting for several years.

Astronomers uncover hidden stellar birthplace

more »
Astronomers have uncovered a hidden stellar birthplace in a nearby spiral galaxy, using a telescope in Chile. The results show that the speed of star formation in the center of the galaxy - and other galaxies like it - may be much higher than previously thought.
