Exploration
at Goddard
At Goddard, exploration is a system that builds outward, grounded in understanding Earth, extending through the space environment, and enabling safe and sustained missions to the Moon, Mars, and beyond.
The Sciences and Exploration Directorate (SED) brings together complementary scientific disciplines that work in concert to make exploration possible. Each contributes in a distinct way, while collectively forming a unified exploration enterprise.

The Corona Australis Molecular Cloud and the Chandelier Cluster
The Southern Crown (Corona Australis) dazzles with young and ancient celestial jewels. The Corona Australis Cloud is a collage of reflection and emission nebulae on the left of today’s image. At 430 light years away, this cloud is one of the closest star-forming regions to Earth. It contains gas cool enough (-260 Celsius or -440 Fahrenheit) to collapse into protostars. Recently formed stars paint blue hues across the cloud as their light reflects off surrounding material. The waltz of the R Coronae Australis binary system stirs up the nebula NGC 6729. The younger of the pair ionizes nearby gas with its ultraviolet light, causing it to glow. The Chandelier Cluster (NGC 6723) dangles from the top right, but is actually tens of thousands of light years farther away than its apparent star-forming neighbor. While NGC 6723 experienced multiple periods of star formation creating slightly younger stars, the chandelier twinkles with stars almost as old as the universe.
