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…

This form of hydrogen, called deuterium, was created a few minutes after the Big Bang, but has been slowly destroyed as it is burned in stars and converted to…
The remediation system aims to protect hundreds of low earth-orbiting satellites from having their onboard electronics ruined by charged particles in unusually…
The LMC is the second closest known satellite galaxy of our Milky Way, orbiting it roughly every 1.5 billion years. Earlier ground-based observations of such…
