Astronomers Discover Colossal 'Super Spiral' Galaxies
2016年3月17日 · Super spirals have long hidden in plain sight by mimicking the appearance of typical spiral galaxies. A new study using archived NASA data reveals these seemingly nearby objects are in fact distant, behemoth versions of everyday spirals.
Super Spiral Galaxies Amaze Astronomers - Scientific American
2015年12月8日 · Super spirals only pop up once in every billion cubic light-years of space, so astronomers have to look a long way to see any. Whereas the best-known giant elliptical galaxy, M87 in the Virgo...
Super Spirals Spin Super Fast - HubbleSite
2019年10月17日 · New research has found that the most massive spiral galaxies spin faster than expected. These “super spirals,” the largest of which weigh about 20 times more than our Milky Way, spin at a rate of up to 350 miles per second (570 km/sec). Super spirals are exceptional in almost every way.
Gargantuan 'super spiral' galaxies loom large in the cosmos - NASA
2016年3月17日 · In archived NASA data, researchers have discovered “super spiral” galaxies that dwarf our own spiral galaxy, the Milky Way, and compete in size and brightness with the largest galaxies in the universe. The unprecedented galaxies have long hidden in plain sight by mimicking the appearance of typical spirals.
Dark matter makes these 'super spiral' galaxies spin surprisingly …
2019年10月23日 · But a few years ago, researchers discovered a new class of jumbo-sized spiral galaxies; astronomers call them “super spirals.” And, in a surprise find published in The Astrophysical Journal...
Super Spirals Spin Faster Than Expected, Astronomers Say
2019年10月18日 · Dr. Patrick Ogle of the Space Telescope Science Institute and his colleagues have found that super spiral galaxies spin faster than expected for their mass, at speeds up to 350 miles per second (570 km/sec); for comparison, the Milky Way -- an average spiral galaxy -- spins at a speed of 130 miles per second (210 km/sec).
Size Matters: Astronomers Discover Rare, ‘Super Spiral’ Galaxies
2016年3月21日 · A team of astronomers has recently discovered a total of 53 ‘super spiral’ galaxies which are enormous in size, three of which are shown in the image above. The galaxies shown at the left and center images also exhibit a double nucleus, which could be the result of a past galactic merger.
Super Spirals Spin Super Fast: Dark Matter Tugs Massive Spiral Galaxies ...
2019年10月20日 · New research has found that the most massive spiral galaxies spin faster than expected. These “super spirals,” the largest of which weigh about 20 times more than our Milky Way, spin at a rate of up to 350 miles per second (570 km/sec). Super spirals are exceptional in almost every way.

Mosaic of Super Spirals - HubbleSite
The galaxy at lower right, 2MFGC 08638, is the most massive super spiral known to date, with a dark matter halo weighing at least 40 trillion Suns. Astronomers have measured the rotation rates in the outer reaches of these spirals to determine how much dark matter they contain.
