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…
Like the flame from a candle, light coming from the surroundings of a black hole is not constant — it flares, sputters and sparkles. “The rapid flickering of…

The findings are published this week in the online edition of the Proceedings of the National Academy of Sciences of the United States of America (PNAS). Hydrogen is the the one of most abundant and lightest element in the universe, and it has been speculated already fifty years back that metallization in pure hydrogen could lead to room- temperature superconductivity, which has been an open question till now. But enormous pressure would be required to compress hydrogen sufficiently in order to achieve this metallic state. …
