Super Spiral Galaxies Amaze Astronomers

They're big, they're bright, they're beautiful—and they shouldn't even exist, at least to our current astronomical knowledge: gargantuan spiral galaxies that make our giant Milky Way seem downright modest. Spirals are supposed to be small fry compared to the greatest giant ellipticals, which are football-shaped swarms of stars thought to be the universe’s biggest and brightest galaxies. 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 such behemoths are born. "I was really surprised," says Patrick Ogle, an astronomer at the California Institute of Technology who discovered the super spirals earlier this year. Ogle looked for them by analyzing the NASA Extragalactic Database, an online compendium of galaxy information. He examined nearly 800,000 galaxies within 3.5 billion light-years of Earth, ranking them by luminosity—in particular, by how much visible light they radiate.

How is that supposed to fit in a 10,000 light year radius visible universe?

Seems only the bands in the spiral galaxies have a lack of turbulence to allow dust and gas to form stars

Where did you ever get the notion that the visible universe had a radius of 10,000 light years? It’s several billion light years. (7 if I remember.)

0bama will fix it. Probably caused by global warming.

Its hard to imagine that a universe with “billions of galaxies” got started with one “big bang”.

Could it be because they have two balls rather than one?

No no no it’s CLIMATE CHANGE, not global warming. Let’s get our narrative right ok???

"Where did you ever get the notion that the visible universe had a radius of 10,000 light years? It’s several billion light years. (7 if I remember.)" Currently, the Universe is estimated to be at least 13.7 billion light years in size according to the survey and measurements of the WMAP satellite taken a few years ago. Supposedly, we cannot see anything past that limit at this time.

That area isn’t even zoned for super-spiral galaxies. Someone got paid off.

“Young Earth” adherents contend the Earth/Universe is 10,000 years old. Thus the light cone for the Earth can only be 10,000 light years radius.

What survey and by what "meaurements?" Please be specific. Thank you.
