Астрономы обнаружили космическую ленту вокруг редкой галактики

Watch how Virtual Reality analysis isolates a newly discovered ring of cold gas orbiting galaxy NGC 4632. Hidden from optical view, this hydrogen gas was revealed by CSIRO’s ASKAP radio telescope, shown in this video. Astronomers discovered that this structure forms a (potential) polar ring. That is, it orbits the galaxy at ~90 degrees relative to its flat, disk-like body. This orientation helps illuminate the distribution of dark matter and theories of how galaxies evolve.
