More
than 100 asteroids were captured in this view from NASA's Wide-field Infrared
Survey Explorer, or WISE, during its primary all-sky survey. In August of this
year, the mission was revived to hunt more asteroids, and renamed NEOWISE.
Not
all of the asteroids are easy to see, but some stand out as a series of dots.
Each dot in a track shows one asteroid, captured at different times as it
marched across the sky. The asteroid at center left is called (2415) Ganesa.
Clusters
of stars can also be seen; for example, NGC 2158 glitters like a jeweled brooch
at center right. There are about 2,500 stars in this view, which is about 30
light-years across.
Clouds
of gas and dust surround the region, visible only in infrared light.
These
data were acquired in March 2010, before WISE was put into hibernation in 2011.
JPL
manages NEOWISE for NASA's Science Mission Directorate at the agency's
headquarters in Washington. The Space Dynamics Laboratory in Logan, Utah, built
the science instrument. Ball Aerospace & Technologies Corp. of Boulder,
Colo., built the spacecraft. Science operations and data processing take place
at the Infrared Processing and Analysis Center at the California Institute of
Technology in Pasadena. Caltech manages JPL for NASA.
