"Discovery of Ultra-Faint Star System Dominated by Dark Matter in Milky Way"

Astronomers have discovered a peculiar system of stars, Ursa Major III/Unions 1 (UMa3/U1), 30,000 light-years away, containing only 60 visible stars and possibly dominated by dark matter. Its nature is uncertain, with two possibilities: a tiny galaxy stabilized by dark matter or a star cluster observed at a unique time. If UMa3/U1 is a dwarf galaxy, it could provide insights into how the Milky Way formed and challenge current understanding of galaxy formation. The system's low luminosity has made it difficult to detect, and its discovery may lead to a new class of extremely faint stellar systems.

"Discovery of New Star System Orbiting Milky Way"

Astronomers have discovered UMa3/U1, the faintest star system ever observed orbiting the Milky Way galaxy, located 30,000 light-years away in the constellation Ursa Major. The system, containing a mere 60 stars spanning about 10 light-years across, poses a mystery as to whether it is a true dwarf galaxy or a star cluster, with the role of dark matter being a key factor. This discovery challenges our understanding of galaxy formation and offers the potential to revolutionize our understanding of the universe's structure.

"Surviving an Ancient Human Story: The Seven Sisters from 100,000 BCE"

Astronomers suggest that the story of the Seven Sisters and Orion, found in various ancient cultures, may date back to 100,000 BCE, making it possibly the oldest story on Earth. The similarity in these myths from cultures with little historical contact is intriguing. Research indicates that the myth may have originated when the Pleiades star cluster appeared as seven stars, with one now too close to another to be distinguished. This finding raises the possibility that ancient human stories could have been shared around campfires in Africa thousands of years ago.

Celestial Spectacle: Moon Converges with Pleiades in Night Sky

This week, the Virtual Telescope Project will be live streaming the Moon as it meets the Pleiades star cluster in the night sky, offering a spectacular celestial event. The Pleiades, also known as the Seven Sisters, is a star cluster in the constellation Taurus, and the live stream will capture the event on February 16 at 20:30 UTC. The star cluster's cultural significance and the intriguing explanation for the myth surrounding it add to the anticipation of this astronomical event.
