Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

Hall thrusters (HTs) are used in earth-orbiting satellites, and also show promise to propel robotic spacecraft long distances, such as from Earth to Mars. The…
Researchers at BYU are the first to 3D-print a viable microfluidic device small enough to be effective at a scale much less than 100 micrometers. Microfluidic…

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are…
When the Moon moves in front of the Sun on Aug. 21, it will completely obscure the Sun's bright face. This happens because of a celestial coincidence – though…
Until now, researchers' understanding has been splintered at best, with mutually incompatible interpretations of the physical processes underlying the…
Because scientists had so many instruments observing the event, they were able to track the entire event from beginning to end, and explain for the first time…
Quantum mechanics describes how matter behaves on the smallest mass and length scales. However, the absence of quantum phenomena in our daily lives has…
