The Shiva and Shakti star streams represent two ancient formations of stars located within the Milky Way galaxy. Named after divine figures in Hindu philosophy that symbolize the creation of the universe, these star streams are believed to be among the earliest structures contributing to the formation of our galaxy, dating back over 12 billion years.
These remarkable star streams were discovered using the European Space Agency's Gaia space telescope. Through Gaia's extensive observations, astronomers were able to analyze the orbits, chemical composition, and content of individual stars within the Milky Way. This analysis led to the identification of the unique structures known as the Shiva and Shakti streams.
The discovery of these star streams is crucial for understanding the early formation processes of the Milky Way galaxy. They indicate that the galaxy originated from multiple long, irregular filaments of gas and dust, which coalesced to form stars and eventually the galaxy itself. This finding helps fill in gaps in our knowledge regarding the Milky Way’s early cosmic history.
The stars within the Shiva and Shakti streams are estimated to be between 12 to 13 billion years old. This ancient age makes them some of the oldest stars in the Milky Way. Studying these stars offers insights into the chemical composition and conditions of the early universe.
While both star streams share similarities in their age and formation, they exhibit distinct characteristics. The stars in the Shakti stream orbit slightly further from the center of the Milky Way and follow more circular paths compared to those in the Shiva stream. This indicates subtle differences in their origins and evolutionary paths within the galaxy.
Future data releases from the Gaia telescope are expected to provide deeper insights into the Shiva and Shakti streams. These observations may also uncover additional ancient structures within the Milky Way, further enhancing our understanding of the galaxy’s formation and its complex history.
