Galaxy Evolution Seen in Action

Posted April 01, 2008 8:41 AM

From Yahoo! News: Science News:

When scientists peer at distant galaxies, it's like looking back in time because their light has taken so long to reach us. Recently, two groups of astronomers were able to see two classes of unique galaxies from the early universe. One group glimpsed galaxies that looked old even when the universe was young, suggesting they must have been some of the first galaxies to form after the birth of the universe. The other group found galaxies dating from the strongest burst of star formation in the universe. The former set of galaxies seem to have reached an advanced stage of life even as the universe was in its infancy.

Sadly, I cannot see the Videos, perhaps because the Internet link to New Zealand is too busy at this time.

I'll try again tomorrow.

Kind Regards....

How can they be so sure that the reddish color is due to dying stars in the galaxy? Isn't it possible that the color is due to some other interference between the very distant galaxy and here, similar to the way a sunset looks red due to the way light is refracted in the atmosphere? I'm no astrophysicist, but I would be curious to know how many other possible sources of this phenomenon were discounted and the reasons behind the decisions. Any ideas? Jorrie?

What a great WayBack Machine! Seems the more we learn, the more we learn there IS to learn. Which, by the way, is probably the good news...
