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…
Therefore CMOS active area space below the OLED electrode is available for additional circuitry in a System-on-Chip setup, including OLED driving (as minor…
The uniqueness of gold and its appreciation as a valuable throughout history is closely related to its exceptional stability to chemical reactions and extreme…
The maps are known as topographic maps because they use contour lines to show the heights of the landscape. The contour lines are superimposed upon…

This research offers scientists new insights in the formation history of the elemental building blocks of the cosmos in which supernovae play a crucial role. The iron in our blood, the oxygen we breathe, the calcium in our bones, the silicon in the sand box, all the atoms we are made of are released during the violent final moments of massive stars in the act of dying. These so-called supernova explosions eject newly made chemical elements into space where they become the building blocks for new stars, planets, or even life. However, many questions concerning the very formation of elements and the way they get distributed across the universe still remain open. …
