This image of the globular cluster NGC 1805 taken by is filled with many colored stars at once. NASA/ ESA Hubble Space Telescope. This tight cluster of thousands of stars is located near the edge of the Large Magellanic Cloud, our own satellite galaxy. Milk Ganga. Bees, like bees, orbit the stars in close proximity to each other. At the Ga ense center of one of these clusters, the stars are 100 to 1000 times closer together than the nearest stars to our Sun, making the arrangement of the planets around them impossible.
The striking contrast in the colors of the stars in this color is beautifully described, combining two different types of light: blue stars, bright in near-ultraviolet light, and red stars, illuminated in red and near infrared. Hubble-like space telescopes can be observed in ultraviolet because it is located above the Earth’s atmosphere, absorbing most of this wavelength, making it inaccessible to ground-based facilities.
This young globular cluster can be seen from the southern hemisphere, in the constellation Dorado, which is Portuguese for dolphinfish. Typically, globular clusters contain stars that are born at the same time; However, NGC 1805 is unusual because it hosts two different populations of stars millions of years old. Observing such clusters of stars can help astronomers understand how stars evolve, and what factors determine whether they end their lives as white dwarfs, or explode as supernovae.
