Stars and Stellar Populations

The Cosmic Origins program is forming a science interest group (SIG) that will help NASA understand and implement recommendations from the upcoming decadal survey in the area of stars and stellar populations.

This group will also sponsor discussions, research seminars, and periodic meetings.

Star cluster Westerlund 2 as observed by the Hubble Space Telescope. The overall scene has an L shaped series of bright clouds at the bottom left, and clearer space toward the top right. There is a bright orange-white star cluster to the cloudy region’s immediate right, just above center. The scene is set against the black background of space, which has blue-white, orange-white, and white points of light scattered all across it.
This young cluster of about 3,000 stars in our Milky Way is called Westerlund 2 and contains some of the galaxy's hottest, brightest, and most massive stars. Hubble's infrared vision pierced dust around this stellar nursery to reveal the dense concentration of stars in the...

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
