Astronomers call the ancient star clusters like the NGC 1786 like “Time Capsule” like their galaxy, and protects some of its ancient stars. A new photo of NASA’s Hubble Space Telescope offers an unprecedented close -up of the dense cluster with 160,000 light years away in the big magelic cloud. Hubble data shows that NGC 1786 includes stars of different ages – amazing finding, since such clumsy was once thought that they were holding the same magnificent breed. This multi -age discovery is renewing our theory of how the galaxies created their first stars, and suggested the early history more complicated.
The stars of mixed age in a galaxy time capsule
According to the official source, this Hubble image depicts the Globalular Cluster NGC 1786, a ball of thick stars in a large magelic cloud of 160,000 light from Earth. Astronomers occupied this photo as part of a program that compared ancient clusters in the nearby dwarf galaxies (such as LMC), with clusters in our own sky. The amazing discovery is that NGC 1786 has hosted several ages stars. In fact, astronomers expected that all the stars in such a shrink would be formed at the same time, so the search for many brilliant generations was unexpected. This shows that other galaxies also have more complex, layered dates than expected in ancient clusters.
The Galaxy Evolution of Evolution
For astronomers, this discovery indicates the formation of the galaxy. Each global cluster is like a snapshot of its galaxy, so finding multiple stringing breeds shows that the big magelic cloud has made its stars in stages rather than at the same time. By comparing the NGC 1786 to the clusters in Akashganga, researchers can withdraw how both galaxies collected their oldest stars. As a NASA scientist notes, this study “can not only tell us how the LMC was actually formed, but also the Akashganga Galaxy”. Overall, this discovery gradually supports the image of the galaxy development through several waves of the stars and the integration, rather than an early burst.
