A new image has been revealed by NASA that was taken by the NASA/ESA Hubble Space Telescope. It shows the globular cluster NGC 1805 which has many colorful stars packed close together. There is a satellite galaxy of our Milky Way called the Large Magellanic Cloud near the edge of which this tight grouping of stars is present. They tend to move around each other in an orbital manner which NASA has compared to “bees swarming around a hive.” The planetary systems around these stars are also speculated to be unlikely because, in the dense center of one of these clusters, the stars are 100 to 1000 times closer together than the nearest stars are to our Sun.
This image combines different types of life and thus illustrates the sharp difference in star colors. Blue stars, shining brightest in near-ultraviolet light, and red stars, illuminated in red and near-infrared. As the Hubble telescope is positioned above the atmosphere of the Earth, it can observe ultraviolet. The atmosphere itself absorbs UV, so the telescopes on the ground are unable to visualize that.
NASA also says that “this young globular cluster can be seen from the Southern Hemisphere, in the Dorado constellation, which is Portuguese for dolphinfish.”
Most of the time, globular clusters contain stars that are born at the same time. But NGC 1805 is different as it appears to have two varying star populations which have a difference of million years in ages. The study of this type of phenomenon can aid researchers and astronomers to understand the evolution of these bodies and determine how the end their lives.
Recently, the NASA/ESA Hubble Space Telescope also captured an image featuring the blue and orange stars of the galaxy called NGC 2188. On a closer first look, the galaxy appears to be made up of a narrow band that produce a mesmerizing look. The astronomers have classified it to be a barred spiral galaxy.
