Tracking the Journey of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Astronomers have tracked the trajectories of three interstellar objects—'Oumuamua, Borisov, and Atlas—revealing they originated from different regions and ages within the Milky Way, providing insights into the diversity of planetary systems and galactic dynamics. These objects serve as natural probes into other star systems, and future observations and missions are expected to expand our understanding of interstellar material and its origins.

Interstellar Star Completes Epic Journey to Black Hole

A star named S0-6, believed to be from outside the Milky Way, has been discovered near the supermassive black hole Sagittarius A*. This interloper star has a chemical composition that matches small satellite galaxies rather than the Milky Way itself, suggesting it has been traveling for a very long time. It is the first star from outside the galaxy to be found near Sagittarius A*, and its discovery raises questions about its origins and whether it has any companions. The study aims to unravel the mysteries of stars near supermassive black holes.
