Thousands of stars are gathered like bees

The Hubble Space Telescope captures brilliant stars lying close together in the globular cluster NGC 1805 in the constellation Dorado.

NASA on September 11 posted a photo of Hubble’s NGC 1805 globular cluster, a space telescope operated by NASA and the European Space Agency (ESA). This cluster of thousands of crowded stars is located near the edge of the Great Magellan Cloud, a galaxy some 160,000 light-years from Earth. The stars in the NGC 1805 cluster are located very close together, like a colony of bees around a hive, NASA observed.

At the center of the globular cluster, the stars can be located 100 to 1,000 times closer to each other than the distance between the Sun and the nearest stars. This makes it impossible to have planetary systems around them.

Hubble’s NGC 1805 shot incorporates a variety of lights. Blue stars are observed in sub-ultraviolet light, while red and near infrared light. Space telescopes like the Hubble can be observed in ultraviolet light because they are located above the Earth’s atmosphere. The atmosphere absorbs most of the ultraviolet rays, so underground stations cannot.

NGC 1805 belongs to the constellation Dorado. Scientists can observe this young globular cluster from the Southern Hemisphere. Globular clusters often contain stars born at the same time. However, it appears that NGC 1805 contains two groups of stars with ages separated by millions of years. Observing such clusters can help scientists understand more about the evolution of stars as well as the determinants of whether they will become white dwarfs or explode with a supernova by the end of their life. .
