That Galaxy With No Dark Matter It's Probably Not Real - SciShow News

The video discusses two major astronomical findings. First, it revisits the galaxy NGC 1052-DF2, initially thought to lack dark matter, but new studies show it has a normal amount. The confusion arose from inaccurate distance measurements. Second, it explores the supermassive black hole Sagittarius A star at the Milky Way's center. Researchers captured the first image of cool gas in its accretion disk, confirming its existence and rotation. These findings enhance our understanding of galaxy formation and black hole behavior.
