Mercury's magnetic field measured by MESSENGER orbiter

Researchers working with NASA's Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft report the frequent detections of Kelvin-Helmholtz (KH) waves at the edge of the innermost planet's magnetosphere. ...

Mini-sensor measures magnetic activity in human brain

A miniature atom-based magnetic sensor developed by the National Institute of Standards and Technology (NIST) has passed an important research milestone by successfully measuring human brain activity. Experiments reported ...

Astronomers detect coolest radio star

(Phys.org) -- Astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emission from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous ...

Study amplifies understanding of hearing in baleen whales

For decades, scientists have known that dolphins and other toothed whales have specialized fats associated with their jaws, which efficiently convey sound waves from the ocean to their ears. But until now, the hearing systems ...

Maglev track could launch spacecraft into orbit

(PhysOrg.com) -- With the aim to make it easier to launch spacecraft into low Earth orbit (LEO), two researchers have turned to maglev technology to catapult a payload hundreds of miles above the Earth. While the concept ...

A new way to measure Earth's magnetosphere

US researchers have demonstrated the potential use of a new way to measure properties of Earth's magnetosphere, the magnetic bubble that surrounds the planet.
