Data from Voyager 1 point to interstellar future
(Phys.org) -- Data from NASA's Voyager 1 spacecraft indicate that the venerable deep-space explorer has encountered a region in space where the intensity of charged particles from beyond our solar system has ...
Most precise measurement of electron mass made
Scientists in Germany said Wednesday they had made the most precise measurement yet of the mass of the electron, one of the building blocks of matter.
At the solar system's edge, more surprises from Voyager
(Phys.org) —Data from NASA's Voyager 1 spacecraft continues to provide new insight on the outskirts of our solar system, a frontier thought to be the last that Voyager will cross before becoming the first ...
Voyager 1 hits new region at solar system edge
(PhysOrg.com) -- NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic ...
X-ray telescopes find black hole may be a neutrino factory
(Phys.org) —The giant black hole at the center of the Milky Way may be producing mysterious particles called neutrinos. If confirmed, this would be the first time that scientists have traced neutrinos back ...

What's important to know about planet Mercury?
Close by the Sun is Mercury, a practically atmosphere-like world that has a lot of craters. Until NASA's MESSENGER spacecraft arrived there in 2008, we knew very little about the planet—only part of it ...
Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers ...
