The European Space Agency (ESA) has selected three NASA-nominated science teams to participate in their planned Euclid mission, including one led by Goddard Space Flight Center.
Engineers working on NASA's James Webb Space Telescope met another milestone recently with they completed performance testing on the observatory's aft-optics subsystem.
The barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers has crowned it the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission.
The sole secondary mirror and a third primary mirror segment that will fly aboard NASA's James Webb Space Telescope arrived on Nov. 5, 2012. A video of the mirrors arriving was released today that shows the arrival of both mirror segments and movement into a giant clean room.
Volume 9, Issue 5 - The thermal shield of the Mid-Infrared Instrument (MIRI) on JWST goes through rigorous environmental testing to ensure it can perform properly in the extreme cold temperatures that it will encounter in space.

Please congratulate Harvey Moseley -- he is the recipient of the SPIE's 2013 George W. Goddard award!
The citation reads: "in recognition of his extraordinary inventions of
superconducting imaging arrays for astronomy, ranging from submillimeter
bolometers to energy sensitive x-ray microcalorimeters, and even dark matter
detectors, as well as microshutter arrays for the James Webb Space Telescope
near-IR spectrometer".
Volume 9, Issue 1 - The James Webb Space Telescope marked another year of significant progress
in 2012 as flight instrumentation was completed and delivered to NASA.
The Observational Cosmology Laboratory conducts research to improve understanding of the origin, evolution and ultimate fate of the universe. Specific issues under investigation include what powered the Big Bang; the size, shape, and matter-energy content of the universe; when the first stars and galaxies appeared and their evolution over cosmic time; and the nature of the mysterious dark energy that is driving the universe apart.
