Save this Title! We can use it again..............

Astronomy Ping!..............

[Obadiah]

The place where Democrats occupy is about the farthest galaxy from reality.

[lurk]

What if there is no edge to the universe?

[CodeJockey]

13 billion years

Is 13 billion a big number? Now what's the national debt?

The new distance measurement also enabled the astronomers to determine that EGS-zs8-1 is was still forming stars rapidly, about 80 times faster than our galaxy.

“O” will impose one by executive order... then there WILL be one!! :)

If it’s expanding, what is it expanding into?..............

[Red Badger]

Those were the days...............

[Praxeologue]

What if there is no edge to the universe?

That would mean that objects of that distance should be found in every direction.

[TigersEye]

Those were the days...............

That's what they're saying on EGS-zs8-1.

If there is an edge to the universe, what’s on the other side?

[ETL]

“an exceptionally luminous galaxy more than 13 billion years in the past”

Meaning it’s more than 13 billion light years away, a light year being the *distance” light travels in a year at its speed of 186,000 miles/second. One light year works out to about 5.9 TRILLION miles. So 13 BILLION x 5.9 TRILLION is how far away this thing is in miles.

Or 76.7 x 1,000,000,000 x 1,000,000,000,000 Miles

Remembered those as a kid, real cool, but limited trunk space :)

Farther than the farthest star?...........maybe not:

We fall off the edge.

[TigersEye]

So 13 BILLION x 5.9 TRILLION is how far away this thing is was in miles.

Except we ain't where we was 13 billion years ago.

[ETL]

But we’re talking about today. Not 13 billion years ago. That galaxy is at a distance 13 billion light years away *today*. 13 billion years ago we were ‘inches’ away from it, or something like that. We were so close we could smell it!

[ETL]

Farther than the farthest star?...........maybe not

Close, but no cigar, exploding or otherwise. The galaxy is MORE THAN 13 billion light years away. The long-dead star that created the gamma-ray burst, a 'mere' 13 billion LY.

From your link...

"April 28, 2009: NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old--less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen.

(snip)

The burst occurred at 3:55 a.m. EDT on April 23rd. Swift quickly pinpointed the explosion, allowing telescopes on Earth to target the burst before its afterglow faded away. Astronomers working in Chile and the Canary Islands independently measured the explosion's redshift. It was 8.2, smashing the previous record of 6.7 set by an explosion in September 2008. A redshift of 8.2 corresponds to a distance of 13.035 billion light years."
