Meteorites show transport of material in early solar system

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, ...

Ultrafast heat conduction can manipulate nanoscale magnets

Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in ...

Infrared observatory measures expansion of universe

(Phys.org)—Astronomers using NASA's Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant, or the rate at which our universe is stretching apart.

Voyager set to enter interstellar space

(PhysOrg.com) -- More than 30 years after they left Earth, NASA's twin Voyager probes are now at the edge of the solar system. Not only that, they're still working. And with each passing day they are beaming back a message ...

Japanese asteroid probe returns to Earth (Update)

A Japanese space probe which scientists hope contains material from the surface of an asteroid returned to Earth on Sunday, Japan's space agency JAXA said, landing in the remote Australian outback.

Japanese space probe Hayabusa close to home

(PhysOrg.com) -- Hayabusa, the Japanese space probe launched in 2003, is returning home from its five-billion-kilometer round-trip journey to collect samples from the asteroid 25143 Itokawa.

Advances in simple crystals for thermoelectric technology

Space probes, gas pipelines, and other applications require an ongoing source of thermoelectric power without direct human maintenance, but current technologies for the corresponding energy conversion are inefficient. Now, ...
