New Class of Galaxy Discovered 104
fructose sends along this excerpt from Space Daily:
"A team of astronomers has discovered a group of rare galaxies called the 'Green Peas' with the help of citizen scientists working through an online project called Galaxy Zoo. The finding could lend unique insights into how galaxies form stars in the early universe. ... Of the 1 million galaxies in Galaxy Zoo's image bank, only about 250 are in the new 'Green Pea' type. Galaxy Zoo is claiming this as a success of the 'citizen scientist' effort that they spearheaded. ... The galaxies, which are between 1.5 billion and 5 billion light years away, are 10 times smaller than our own Milky Way galaxy and 100 times less massive. But surprisingly, given their small size, they are forming stars 10 times faster than the Milky Way. 'They're growing at an incredible rate,' said Kevin Schawinski, a postdoctoral associate at Yale and one of Galaxy Zoo's founders. 'These galaxies would have been normal in the early universe, but we just don't see such active galaxies today. Understanding the Green Peas may tell us something about how stars were formed in the early universe and how galaxies evolve.'"

My pre-teen kids LOVE Galaxy Zoo...they feel they're really helping push out the boundaries of knowledge, and I get lots of teachable moments.

Indeed, and they also missed out on calling these Galactica, instead of Green Peas
Just random chance we see no recent ones? (Score:5, Interesting)
Given their density within the 5 billion light year sphere, it should be possible to calculate the odds of having 1.5 billion light years to the closest one.

10^1 times smaller = 10^-1 times bigger, never really managed to see the problem with it. It's perfectly unambigious since it makes no sense to refer to less than nothing. Things like there/their/they're that actually have three different meanings are much more annoying.

I'm just an ignorant computer geek, so I'd like to know how these galaxies are growing.
Are they simply superdense and spawn new stars as they expand? Or are they drawing material from some outside source?
Here's my totally crackpot theory: Green Pea galaxies are fed from "white holes" (tm) that spew raw material into the nascent galaxy. These "white holes" (tm) are connected via wormholes to black holes. The raw material gets sucked into the black hole, transits the connecting wormhole, and then gets spewed out the "white hole" (tm) into the center of the Green Pea. That's totally hot! No applause please, just hand me my honorary Ph. D. in astrophysics.

Isn't there some sort of theory about time and it's constant slowing or something? If something appears 5 billion light years away and yet appears to be forming stars 10 times faster than our local system, could that not be somehow relevant to the passage of time either 5 billion years in the past?
If you can't read this because, when I press post, the entire universe changes into something completely new, then I'll know that this means that I was right and that I fucking solved it.
If you can read this line, then let it be known that I've had a lot of coffee this morning, and very little food. That's my story and I'm sticking to it.
