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…
The space terminal for the Lunar Laser Communication Demonstration (LLCD), NASA's first high-data-rate laser communication system, was recently integrated onto…
The study, published in Science, found, among other things, evidence of a much-discussed intermediate state before molecules bind to or leave a metal surface….
Exactly how these clearings form and why they're only found near the planet’s equator have long been mysteries. Now, using images from NASA's Cassini…
The finding provides astrophysicists with additional insight into how planets are formed. “This is the sharpest spectrum ever obtained of an extrasolar…
