Our IRIS mission launched 8 years ago today! IRIS observes how solar material moves, gathers energy, and heats up as it travels through a little-understood region in the Sun’s lower atmosphere. Explore IRIS science at http://nasa.gov/iris.

Happy Launch Anniversary IRIS! The mission to study the solar atmosphere was placed in orbit by a Pegasus XL rocket. The Pegasus was released from the “Stargazer” L-1011 carrier aircraft. IRIS is a mission to observe how solar material moves and gathers energy

Did you know a massive star is sort of like an onion? Before it dies as a supernova, it consists of multiple layers of different chemical elements from hydrogen at the surface down to iron at the core. https://go.nasa.gov/3hbiqvl #OnionDay

@NASA_Wallops TWEET

We were pleased to welcome Maryland @GovLarryHogan to Wallops to tour our range control center, sounding rockets fabrication and test facility, @VCSFA_MARS launch complex, and @NorthropGrumman Antares rocket.

This NASA/ESA @HUBBLE_space Telescope image is one of the sharpest wide-angle views taken of Messier 82 (M82), a galaxy remarkable for its flame-like plumes of glowing hydrogen blasting from its central regions where young stars are being born
