"Without GALEX's ability to detect the ultraviolet light of the youngest, hottest stars, we would never have recognized the full extent of this intriguing system," lead scientist Rafael Eufrasio of NASA's Goddard Space Flight Center in Greenbelt, Md., and the Catholic University of America, said in a statement. But it has only now been crowned champion, after detailed study of data gathered by a number of instruments, including NASA's Galaxy Evolution Explorer spacecraft, or GALEX. NGC 6872 has ranked among the largest known spiral galaxies for decades. It is believed that bars act a bit like a funnel, pulling matter into the bulge from the disk.
Most of the galaxies that scientists have discovered so far are. NGC 811 is a Spiral Galaxy located in the constellation of Cetus. Spiral galaxies are twisted collections of stars and gas that often have beautiful shapes and are made up of hot young stars.
They affect the motions of stars, dust and gas. Samsung Galaxy A11 - Activate / Set Up Device For info on prepaid service activation. Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequence.Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. Bars are found in up to 65 of spiral galaxies. The Triangulum Galaxy is a spiral galaxy with no central bar and its loosely wound arms emanate from the galactic core. The distance between NGC 6872's two huge spiral arms is 522,000 light-years, compared to about 100,000 light-years for the Milky Way.

The title-holder is now NGC 6872, a barred spiral found 212 million light-years away in the southern constellation Pavo, researchers announced Thursday. Astronomers have crowned the universe's largest known spiral galaxy, a spectacular behemoth five times bigger than our own Milky Way.
