NGC 2158
NGC 2158 is a globular cluster located in the constellation Gemini. It is approximately 16,000 light-years away from Earth and is estimated to be around 2 billion years old. The cluster contains thousands of stars tightly packed together, making it a fascinating object for astronomers.
Discovered by William Herschel in 1784, NGC 2158 is often studied to understand the formation and evolution of star clusters. Its stars are primarily older, red giants, which provide insights into the life cycles of stars and the dynamics of globular clusters in the universe.
