The WISE mission is now over, with the spacecraft taking its final image on Feb. 1, 2011. WISE was a “cool” infrared mission, with the optics chilled to less than 20 degrees centigrade above absolute zero (20 Kelvins). In its low Earth orbit (523 km above the ground), the spacecraft explored the entire Universe and collected infrared light coming from everywhere in space and studied asteroids, the coolest and dimmest stars, and the most luminous galaxies. Expect to hear and see more from WISE, however in the future. More images will be released from the team in April and in the spring of 2012. Here’s a look back at some of the great images from WISE’s 13 months in space:
And if you want to see how it all started, here’s a video of WISE’s launch:

Nothing sweeter in success than knowledge gained!
Why do scientist and others insist upon using “centigrade” for temperature when degree Celsius should be used. Centigrade is not an SI unit for temperature. And Kelvin, the official SI unit for temperature, does not have an “s” at the end. As a retired science teacher I would expect that American scientist and writers of science would know the difference.
@StarzDust: For everyday use, there is no appreciable difference between the Celsius and Centigrade scales. The difference is that the 0 point on the Celsius scale is set at the triple point of water as defined at 273.16 kelvin instead of the freezing point of water which is difficult to accurately determine. Since the Celsius scale is defined in kelvin, there is no error in accuracy between using Celsius and kelvin, and Celsius is much easier for the layman to relate to.
As Wikipedia points out here:
The name for the centigrade temperature scale was changed to Celsius in 1948. They are same scales. I agree that it is a bit strange that some people insist on using the old term.
