NASA satellite images: Hubble images show ‘pocketful of stars’ on edge of Milky Way

NASA said: “The striking difference in star colours is illustrated beautifully in this image, which combines different types of light: blue stars, shining brightest in near-ultraviolet light, and red stars, illuminated in red and near-infrared.

“Space telescopes like Hubble can observe in the ultraviolet because they are positioned above Earth’s atmosphere, which absorbs most ultraviolet light, making it inaccessible to ground-based facilities.

“This young globular cluster can be seen from the Southern Hemisphere, in the Dorado constellation, which is Portuguese for dolphinfish.

“Usually, globular clusters contain stars that are born at the same time. NGC 1805, however, is unusual as it appears to host two different populations of stars with ages millions of years apart.
