In a turbulent magnetic environment, magnetic field lines become scrambled. As the field lines cross, intense electric currents (shown here as bright regions) form and eventually trigger magnetic reconnection (indicated by a flash), which is an explosive even…
Ver en NASA ↗There are millions of asteroids in our solar system, so why is NASA going to the asteroid Psyche? Scientists hypothesize that this particular asteroid, which orbits the Sun between Mars and Jupiter, could be part of the metal-rich interior of a planetesimal, …
Ver en NASA ↗Bright swaths of red and green, known as airglow, are visible in this time-lapse view of Earth's limb captured from the International Space Station. Airglow occurs when gases in the upper atmosphere become charged by the Sun's radiation, emitting light. By me…
Ver en NASA ↗During the June 2011 lunar eclipse, scientists will be able to get a unique view of the moon. While the sun is blocked by the Earth, LRO's Diviner instrument will take the temperature on the lunar surface. Since different rock sizes cool at different rates, s…

Ver en NASA ↗A coronal mass ejection burst off the side of the sun on May 9, 2014. The giant sheet of solar material erupting was the first CME seen by NASA's Interface Region Imaging Spectrograph, or IRIS. The field of view seen here is about five Earth's wide and about …
Ver en NASA ↗BRUCE BUCKINGHAM: Okay, thank you. Let's move on to the next question. This is from Sandy in St. Augustine: Can you explain the difference between the GOES and the POES spacecraft? ANDRE' DRESS: That's, Sandy, that's a good question. The difference is primar…
