Extremely exciting

I've got a piece on that to publish to my site, tomorrow.  The discovery came from a nice mix of x-ray telescope, spectroscopy and microlensing...

When Oklahoma makes the Geek tab instead of wingnut okies making the Politics tab, we got to celebrate.

FTA: 3.8 billion light years away, or one-third of the distance across the observable universe.

Umm...wrong.

Not necessarily.  There is more than one way to measure it.  If it is distance that light traveled then the max light can have traveled is 13.8 light years (give or take that figure might change a little but not much). 3.8 times three is a bit smaller than that but I don't think that was meant to be a precise calculation.  The other way to measure distance is to calculate how far the object is "today."  As the universe is expanding the distance is farther then it was when the observed light passed the exoplanet.  By that measure it is not even close.  One could also calculate how long light from a flashlight you are holding would take for a return journey.  I believe it is far enough that that it will never reach it because of the universe's relentless expansion.  Hey one third of infinity is infinity.  It works out. ;-)

I think this thread is a REPEAT from last week, but at least there's more interest in appropriate musical videos in this thread.

As I posted in the other, looks like these people need to add another verse (or two) to this one:

3.8 billion years ago that light originated in that spot. Farkall if it's there now.

Expanding universe says it's probably way farther away today...or doesn't exist at all.

Even if you wanted to really simplify things and just say the observable universe from Earth is a sphere with a radius of 13.8 billion light-years, it is still just the radius. And roughly 1/3 of the radius would only be 1/6 of the way "across the observable universe."

but infinity times infinity is a guaranteed win, because nobody listens to the nerdy kid with glasses.

And its kind of cool and all.  But regular people read this and say "wow that's cool that we can see planets. I wonder of there are people there.. or whatever."....  And of course its immaterial.

Seeing a planet that was there 3.6 billion years ago really doesn't mean a whole lot.  Its a silicon atom in a grain of sand on a seashore long gone.
