SOHO and EPOXI combined forces to provide observations on Comet Hartley 2 -- which appears to be an irregular comet, belching chunks of ice and losing water at a surprisingly fast pace.
Ripples in the sun's magnetic field called Alfven waves have been shown to carry more energy than previously thought, possibly enough to drive the intense heating of the corona and to speed the solar wind to 1.5 million mph.
The second of the two ARTEMIS spacecraft entered lunar orbit Sunday morning.
NASA researchers have made use of old mathematical techniques and new insights on how CMEs travel.
NASA has just released new high-resolution videos of the solar event recorded by SDO on June 7, 2011.
For the first time ever, SDO has captured a movie of a comet streaking directly in front of the sun.
Noctilucent clouds are back for 2011 and continue spreading to ever lower latitudes.
This July, scientists will launch four rockets from NASA Wallops Flight Facility to study how space winds and charged particles affect the way each other move, causing dynamo currents through the lower atmosphere.
The first of the two ARTEMIS spacecraft entered lunar orbit this morning. ARTEMIS was the first mission to orbit the moon's Lagrangian points and this is the first ever attempt to move from the Lagrangian into lunar orbit.
It took one and a half years, over 90 orbit maneuvers, many gravitational boosts and little fuel to move two spacecraft from their orbits around Earth to their new home around the moon.
