Space & Earth Science

Phys.org provides the latest news on astronomy and space exploration.
  1. Satellites have detected powerful solar flares in the last two months, but this phenomenon has been recorded for over a century. On 10 September 1886, at the age of just 17, a young amateur astronomer from Madrid, using a modest telescope, observed one of these sudden flashes in a sunspot. He wrote about what he saw, drew a picture of it, and published the data in a French scientific journal. This is what researchers from the Instituto de Astrofísica de Canarias and the Universidad de Extremadura have recently found.
  2. Hidden beneath Chamber A at the Johnson Space Center is an area engineers used to test critical contamination control technology that has helped keep our James Webb Space Telescope clean during cryogenic testing.
  3. A spacecraft destined to explore a unique asteroid will also test new communication hardware that uses lasers instead of radio waves.
  4. Curtin University planetary scientists have shed some light on the evolution of asteroids, which may help prevent future collisions of an incoming 'rubble pile' asteroid with Earth.
