Stars Without Galaxies! |Urdu/Hindi| Kainaat Astronomy in Urdu

Our Sun is part of the Milky Way galaxy. But can there be stars without a galaxy? And if so, how do they get out of the galaxy? Over the past couple of decades, astronomers have started detecting inter-galactic stars, stars that reside in the space between galaxies. As it turns out, these stars can provide us with important information about the distribution of dark matter as well. Please join astrophysicist Salman Hameed to talk about these rogue stars in this episode of Kainaati Gup Shup.
