An unexpectedly strong blast from the Sun hit Mars this month, observed by NASA missions in orbit and on the surface. NASA announced Friday that a coronal mass ejection from the Sun on September 11 was so strong that charged particles caused a planet-wide aurora on Mars. According to team members of NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, the solar event caused the entirety of Mars to light up in ultra-violet light. The aurora was also 25 times brighter than any event seen by the MAVEN orbiter thus far. The orbiter has been studying the atmosphere of Mars since 2014.

“Jellyfish Dreams” –Caltech: Sleep is an Ancient Behavior, Untouched by Millennia of Evolution (WATCH Today’s ‘Galaxy’ Stream)

Jellyfish and humans may seem wildly different, but both still need to sleep. At first glance, humans seem to have very little in common with Cassiopea, a primitive jellyfish. Cassiopea is brainless, spineless, and spends essentially its entire life sitting upside down on the ocean floor, pulsating every few seconds. However, Caltech scientists have now discovered that, as different as our daily schedules may seem, humans and jellyfish actually start and end their days with the same behavior: sleep. This finding that jellyfish sleep implies that sleep is an ancient behavior, largely untouched by millennia of evolution.
