5 AMAZING stars we’ve discovered in space!

The video explores various unusual stars in the universe, starting with UY Scuti, the largest known star, and J0523, the smallest. It discusses the Black Widow pulsar, a neutron star with a companion, and SM0313, the oldest star. The video concludes with an introduction to Thorne-Zytkow objects, hybrid stars formed from neutron stars and supergiants.
