Kickstarting tiny satellites into interplanetary space (w/ Video)
(Phys.org) —Two University of Michigan engineering professors are turning to the Kickstarter online community to help fund an interplanetary satellite mission.
The heart of space weather observed in action
Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field ...
NASA Voyager statement about competing models to explain recent spacecraft data
(Phys.org) —A newly published paper argues that NASA's Voyager 1 spacecraft has already entered interstellar space. The model described in the paper is new and different from other models used so far t ...
Overnight aurora sets sky on fire, more possible tonight
I'm writing this at 1:30 a.m. running on what's powering the sky over northern Minnesota right now – auroral energy. Even at this hour, rays are still sprouting in the southern sky and the entire north ...
New approach advances wireless power transfer for electric vehicles
Researchers from North Carolina State University have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver – moving engineers closer to ...
Controlling magnetism with an electric field
There is a big effort in industry to produce electrical devices with more and faster memory and logic. Magnetic memory elements, such as in a hard drive, and in the future in what is called MRAM (magnetic random access memory), ...
Female astronauts have a lower threshold for space radiation than their male counterparts
Why are there more men than women in space? The answer might not be as straightforward as you first think. According to physiological models used by NASA, female astronauts have a lower threshold for space ...
How magnetic crustal fields affect planets
If you are ever lost on the surface of Mars, don't count on a compass to help you get home. On Mars, compasses don't work.
Physicists pay homage to the SQUID at 50
From humble beginnings in a series of accidental discoveries, SQUIDs have invaded and enhanced many areas of science and medicine, thanks, in part, to the National Institute of Standards and Technology (NIST).
This energy-boosting region in the Sun will have a new NASA satellite watching it
How does the sun's energy flow? Despite the fact that we live relatively close (93 million miles, or eight light-minutes) to this star, and that we have several spacecraft peering at it, we still know little ...
Magnetic field may shape 'blooming' star
(Phys.org) —An old star, IRAS 15445-5449, has begun to push out a jet of charged particles that glow with radio waves.
Infrared vision lets researchers see through—and into—multiple layers of graphene
(Phys.org) —It's not X-ray vision, but you could call it infrared vision.
Researchers 'light' magnetic fire and analyse how energy propagates
The propagation of the so-called 'magnetic fire' in certain systems seems to be "the only combustion process ruled by quantum laws known in the nature", points out Javier Tejada, Professor of Condensed Matter ...
Solar tsunami used to measure Sun's magnetic field
(Phys.org) —A solar tsunami observed by NASA's Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field.
