On Second Thought, Polaris Really Does Seem 434 Light Years Away
sciencehabit writes with this excerpt from Science Magazine "Last November, astronomer David Turner made headlines by claiming that one of the sky's best known objects—the North Star, Polaris—was actually 111 light-years closer than thought. If true, the finding might have forced researchers to rethink how they calculate distances in the cosmos as well as what they know about some aspects of stellar physics. But a new study argues that distance measurements of the familiar star made some 2 decades ago by the European Space Agency's venerable Hipparcos satellite are still spot on."
Frost Piss for All!
And Warp 11 ?? Can one travel at Warp 11 ??
Looks like another mixup between metric and imperial measurement systems. /jk
...eleventy-one light years is far too short a distance to travel among such excellent and admirable stellar phenomena.

Start 3D printing a really long string and when we "private space" our way there (for vacations and exploring and what not), just spool out the string and measure it. I mean, physics is just something we can reinvent as we please, and surely we'll find new particles and stuff to totally make this possible, right?
Right?
Do they have a Stargate?
I'm not a complete idiot... Some parts are missing.
Polaris is a sneaky, underhanded, deceitful star, not to be trusted. Fortunately, in about 15,000 years, it will no longer be the north star. Sir Alop
It still doesn't mean that Turner is wrong. Remember Piltdown Man? Even people who are committed to science sometimes still get it terribly wrong.
Probably an error converting between metric light-years and American light-years.
You sniff dog anuses! You are higher than Judy Garland! You from sheer exhaustion on a dead man's chest is punishment enough! You can see the clerk! Devil! Devil! Devil! Devil! Devil! Assgoat! Devil! TV1!!!!

Am I the only one who first read "Solaris Really Does Seem 434 Light Years Away"? ..
Man, I'm glad I was sitting
The Polarans solved FTL travel ages ago, and now use it to troll other civilisations by placing their star along some life-bearing planet's axis of rotation, waiting for people to develop advanced astronomy, then randomly feinting at them to mess with the scientists' heads.
Treat the Universe as a jigsaw puzzle. Figure out some phenomena in space that would be affected by a difference in measurement. If the results using Turner's method would allow the phenomena to fit better with actual knowns, Turner's probably right. There are so many crazy phenomena in the Universe, and I wonder how much of it would be less crazy and more expected if some common beliefs were overturned.
If we had the Deathstar we could end the controversy with one shot.
Can anyone recommend me a site with astronomical news and comments without 90% dumbass failed-funny comments as here on /.?
... It lunges at you when you turn away or blink.
Geeks are so full of shit that "beating the crap out of them" takes a whole new meaning.
It's 1000 light years from home.
You are welcome on my lawn.
Reading up, it turnes out the whole argumentation is exactly the other way round than I would hav eexpected.
You can meassure the distance of stars in multiple ways, most depend on assumptions that can be pretty hard to get right. There is ONE way, though, to accurately determine the distance:
By simple geometry. If you observe the star 6 months apart, you get a trianble with a base of 2AU, which is enough accurately triangulate the distance of stars up to a some 100 ly away.
This was exactly the method used 2 decade ago.
Not this new guy used a very indirect way (measuring the brightness we see the star, guessing its real brightness by looking at spectra and then deciding how far away it must have been), gets a 30% different number and claims his, indirect and error-laden, way is yielding the more correct of the results.
Tard.
HI O WISE PRINCE. WHT TOOK U SO DAM LONG?
are closer than they appear. Gotta stop using mirrors in telescopes to get accurate readings.
Hell, when I shave in the mirror it looks like I'm like 3 feet away from me... I know I'm much closer than that.
Who is implicated in the Lanney Kekua scam?
Is Mr. Mani Te'o innocent in all of this. That he lied about meeting Ms. Kekua so his dad and others wouldn't think less of him for being head-over-heels for a virtual girlfriend?
Does the set of geek dudes who are too shy to have a real girl friend intersect the set of star college football players?
If Mani's musician-dude friend is behind the thing, does the musician have a serious man-crush on Mr. Te'o?
Forget the parallax of Polaris, these are the questions that demand answers.
