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…
Every 25.34 days, the object, designated LRLL 54361, unleashes a burst of light. Although a similar phenomenon has been observed in two other young stellar…
Though several models predict this behavior and evidence from supernovae points in this direction, actually observations of such pre-explosion outbursts have…
X-ray microscopy requires radiation of extremely high quality. In order to obtain sharp images instrument and sample must stay absolutely immobile even at the…
However, particles from inside the solar system bounce off this boundary and neutral atoms from that collision stream inward. Those particles can be observed…
