Where In The Universe #129

by Nancy Atkinson on December 16, 2010

Here’s this week’s image for the Where In The Universe Challenge, to test your visual knowledge of the cosmos. You know what to do: take a look at this image and see if you can determine where in the universe this image is from; give yourself extra points if you can name the spacecraft/telescope responsible for the image. We’ll provide the image today, but won’t reveal the answer until later. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.

UPDATE: Answer now posted below.

This is part of the Orion Nebula showing a colony of hot, young stars, and was taken by the Spitzer Space Telescope. The hottest stars in the region, called the Trapezium cluster, are bright spots at center right. Radiation and winds from those stars has sculpted and blown away surrounding dust. The densest parts of the cloud appear dark at center left.

This image is a combination of data from Spitzer and the Two Micron All Sky Survey (2MASS). The Spitzer data was taken after Spitzer’s liquid coolant ran dry in May 2009, marking the beginning of its “warm” mission. Light from Spitzer’s remaining infrared channels has been color-coded: 3.6-micron light is green and 4.5-micron light is red. 2MASS 2.5 micron light is blue.

See more about this image on the Spitzer website.
