The Source of the Solar Wind Energy Discovered

  Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the Sun for a closer look. The solar wind [continue reading]

Research Brings Light to Star Mystery

  Scientists at Northumbria University have begun to unlock the mystery of why the outer edge of the Sun is much hotter than its surface for the first time.  Magnetic loop structures in the corona of the Sun. A team led by Northumbria’s Dr Richard Morton, and including researchers from the University of Sheffield and [continue reading]

Meteorites Reveal Warm Water Existed on Mars

  Hydrothermal fractures around Martian impact craters may have been a habitable environment for microbial life   The study determined that water temperatures on the Red Planet ranged from 50°C to 150°C. Microbes on Earth can live in similar waters, for example in the volcanic thermal springs at Yellowstone Park, the scientists behind the research point [continue reading]

Snow And Ice on Oven-Hot Venus?!

  Venus Express has spied a surprisingly cold region high in the planet’s atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow. This image of the Venus southern hemisphere illustrates the terminator – the transitional region between the dayside (left) and nightside of the planet (right). The south [continue reading]

Peering Into Coronal Prominence Cavities

  The Sun’s atmosphere dances. Giant columns of solar material – made of gas so hot that many of the electrons have been scorched off the atoms, turning it into a form of magnetized matter we call plasma – leap off the Sun’s surface, jumping and twisting. Sometimes these prominences of solar material, shoot off, [continue reading]
