 Many colorful stars are packed close together in this image of the globular cluster NGC 1805 taken by Hubble. This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud. In the dense center, stars are 100 to 1000 times closer together than the nearest stars are to our Sun. This makes planetary system formation around them highly unlikely. The striking difference in star color is illustrated beautifully in this image, which combines two different types of starlight. Blue stars shining brightest in near ultraviolet light and red stars illuminated in red and near infrared. Usually globular clusters contain stars which are born at the same time. However NGC 1805 is unusual as it appears to host two different populations of stars with ages of the older red stars being millions of years older than the blue young stars.
