Where In The Universe #47

By Nancy Atkinson - March 18, 2009 03:15 PM UTC | Extragalactic

Are you ready for another Where In The Universe Challenge? Take a look at the image above and see if you can name where in the Universe this image is from. Give yourself extra points if you can name the spacecraft responsible for the image. We'll provide the image today, but won't reveal the answer until tomorrow. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Check back tomorrow on this same post to see how you did. Good luck!

UPDATE:

The answer has now been posted below. Don't peek before you make your guess!

This is an image of the Pleiades star cluster, also known as the Seven Sisters, taken by the Spitzer Space Telescope. The Pleiades, located more than 400 light-years away in the Taurus constellation, are the subject of many legends and writings. Greek mythology holds that the flock of stars was transformed into celestial doves by Zeus to save them from a pursuant Orion. The 19th-century poet Alfred Lord Tennyson described them as "glittering like a swarm of fireflies tangled in a silver braid."

This image from Spitzer highlights the "tangled silver braid." The spider-web-like network of filaments, colored yellow, green and red in this view, is made up of dust associated with the cloud through which the cluster is traveling. The densest portion of the cloud appears in yellow and red, and the more diffuse outskirts are shown in green hues. One of the parent stars, Atlas, can be seen at the bottom, while six of the sisters are visible at top. Additional stars in the cluster are sprinkled throughout the picture in blue.

How did you do? Come back again next week for another WITU Challenge.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
