Hubble Views the Star That Changed the Universe
NASA ^ | Monday, May 23, 2011 | unattributed

Posted on 05/23/2011 8:55:01 PM PDT by SunkenCiv

NASA's Hubble Space Telescope has been trained on a single variable star that in 1923 altered the course of modern astronomy. V1 is a special class of pulsating star called a Cepheid variable that can be used to make reliable measurements of large cosmic distances.

Thanks decimon!
The star helped Hubble show that Andromeda was beyond our galaxy and settled the debate over the status of the spiral nebulae. The universe became a much bigger place after Hubble's discovery, much to the dismay of astronomer Harlow Shapley, who believed the fuzzy nebulae were part of our Milky Way.
Well, this is one of *those* topics, but for a different (though obvious) reason.

Prior to the discovery of V1 many astronomers thought spiral nebulae, such as Andromeda, were part of our Milky Way galaxy. Others weren't so sure. In fact, astronomers Shapley and Heber Curtis held a public debate in 1920 over the nature of these nebulae. During the debate, Shapley championed his measurement of 300,000 light-years for the size of the Milky Way. Though Shapley overestimated its size, he was correct in asserting that the Milky Way was much larger than the commonly accepted dimensions. He also argued that spiral nebulae were much smaller than the giant Milky Way and therefore must be part of our galaxy. But Curtis disagreed. He thought the Milky Way was smaller than Shapley claimed, leaving room for other island universes beyond our galaxy.
Shapley was just plain wrong, calling him correct when he was so very, very wrong is just a courtesy to a Marxist piece of trash that deserves none.

And here I was thinking the article was going to discuss a different star:

I never thought I'd do this, but hey, it's been almost two weeks. ;') Consider this an "extra extra" ping. Now it's past my bedtime.

Please add my name to this list! I have been hoping to find a good web site to view such photos if you can suggest one, Sc.

Cephid Variables must be female stars.

Article says they blink, and have a 31 day ‘period’.

“Well, this is one of *those* topics, but for a different (though obvious) reason. “

Schadenfreude would work better were the dirty rotten bastard still alive. If it weren’t him there would have been another who’d have made life difficult for non-uniformitarians. It can’t be long before you find a reason to dig Sagan up so we can mock him instead. I’d like that even more.

Not quite the same thing as "changing the universe".

Misuse of the anthropic principle?

I love it when scientists talk in technical terms.

I always liked this photo for how it accentuates the incredible world we live in and the value of life. Cheers.

My favorite recollection of Sagan was an old “educational” video of a young Sagan who kept confusing red shift and blue shift. He hadn’t quite got the rote memorization, editing out of the past, and plagiarism down that served him so well later in life.
