2015年12月8日 · But now a search across billions of light-years has snared a rare breed of "super spiral" galaxies that rival their giant elliptical peers in size and luminosity, raising questions over how...

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.

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.

2019年10月23日 · Astronomer Patrick Ogle was looking into the brightest galaxies recorded in galaxy surveys when he stumbled across super spirals — spiral galaxies with 10 to 20 times as much visible matter...

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.

2019年10月18日 · Super spirals are very luminous — they can shine with anywhere from 8 to 14 times the brightness of our Milky Way Galaxy. They are also giant and massive, with a diameter up to 450,000 light-years and stellar mass between 30 and 340 billion solar masses. Only about 100 super spiral galaxies are known to date.

2016年3月17日 · Using archived NASA data, researchers have discovered “super spiral” galaxies that dwarf 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.

2016年3月18日 · This galaxy, named SDSS J094700.08+254045.7, is one of the biggest and brightest super spirals; its starry disk and spiral arms stretch about 320,000 light-years across, or more than three times the breadth of our Milky Way Galaxy.

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.

2016年3月18日 · These newfound galaxies, which the team calls superluminous spirals or “super spirals” for short, have disks between 180,000 and 440,000 light-years wide, and they’re churning out stars at a rate of 5 to 65 Suns each year.
