Educational Coma Cluster of Galaxies

Coma Cluster of Galaxies

A picture is worth a thousand words. Especially a picture of thousand galaxies!

Click on this link to see the original high definition Hubble image of  the Coma Cluster in which the intricate details of the bluish galaxy upper left part of the photo are visible. Most spots of light in the image are galaxies but those in the background do not belong to one of the densest clusters known to the human race living on Planet Earth.

Contemplate on the spectacular image as it is a highly educational experience - especially with the help of the short accompanying text in APOD. The vastness of the Cosmos is so difficult to grasp just by reading words. Seeing this picture, and others like it, with physical light reaching Hubble Space Telescope cameras from the deep space is therefore a unique educational tool in learning to grasp things in galactic scale.

Just looking and contemplating the view in the comfort of your own home and computer screen is studying Astronomy at its best - this is it, the real thing, genuine light from billions of stars organized into these mostly oval structures!
