Typically, spherical clusters have stars that originate at the same time, NASA said. But NGC 1805 is unusual – scientists believe it has two distinct populations of stars that are millions of years apart.
NASA compared the close orbit of the star to the honeybee hive. The agency said that it is unlikely that the stars in the center will be orbited by the planets, as they are 100 to 1,000 times closer, higher than our Sun than the nearest stars.
The cluster “Dorado” appears from the southern hemisphere in the planetarium, which is the Portugese for dolphinfish.
The Hubble position in space provides the unique ability to capture different wavelengths of light. Earth’s atmosphere absorbs the most ultraviolet light, making it impossible to distinguish clusters in star colors from the ground to observe.
The image combines different types of light to highlight notable differences in star colors – blue stars, brightest near ultraviolet light, and red stars, bright in red and near infrared.
Astronomers are interested in observing groups such as NGC 1805 to learn more about the evolution of stars, as well as what factors led to their death.Vs explosive .
