Circumstellar Disks HD 141943 and HD 191089
The two images at top reveal debris disks around young stars uncovered in archival images taken by NASA's Hubble Space Telescope. Hubble's Near Infrared Camera and Multi-Object Spectrometer observed the disks in near-infrared light in 2007. Astronomers used a coronagraph to block out the bright light from each star so they could analyze the faint, reflected light off dust particles in the disks. The illustration beneath each image depicts the orientation of the debris disks. Astronomers retrieved these images from the Barbara A. Mikulski Archive for Space Telescopes (MAST) and used more powerful image analysis techniques to search for planetary systems.

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
