BTW, if you haven't seen the IMAX film of Hubble, its just fascinating and incredibly beautiful.

Hubble sees far, far back in time...

Astronomers Spot Record Distant Galaxy From Early Cosmos
March 03, 2016 - Astronomers say they have discovered a hot, star-popping galaxy that is far, far away — farther than any previously detected, from a time when the universe was a mere toddler of about 400 million years old.

By employing a different technique — one that has raised some skepticism — a team of astronomers exposed a time period they'd thought was impossible to observe with today's technology. They used the Hubble Space Telescope and found the light wave signature of an extremely bright galaxy 13.4 billion light-years away, according to a study published Thursday by Astrophysical Journal. The margin of error is plus or minus 5 million light-years. A light-year is about 5.8 trillion miles. It shatters old records for distance and time in a big way, and may remain the farthest that can be seen for years, until a new space telescope is launched, the team of astronomers said.

With that light signature, astronomers were able to produce a photo of this galaxy that's fuzzy and all-too deceptive in color. It appears darkish red and indistinct, when in reality it's so hot it is bright blue, but the light has traveled so long and far that it has shifted to the very end of the color spectrum, to dark red. And that fuzziness masks an incredible rate of star formation that's 10 times more frenetic than our Milky Way, said study co-author Gabriel Brammer, an astronomer at the Space Telescope Science Institute. "It really is star bursting," Brammer said. "We're getting closer and closer to when we think the first stars formed ... There's not a lot of actual time between this galaxy and the Big Bang." If we were back in time and near this galaxy (named GN-z11), we'd see "blue, stunning, really bright young stars" and all around us would be "very messy looking objects" that are galaxies just forming — not the large bright spirals we think of as galaxies, said study co-author Garth Illingworth at the University of California Santa Cruz.

Hubble spectroscopically confirms farthest galaxy to date.​

Astronomers measure the distance an object by calculating how much the light changes from blue to red, called redshift. This discovery is of a galaxy with redshift of 11.1; until this discovery, the previous highest redshift was 8.68, about 580 million years after the Big Bang. For a long time, competing teams of astronomers were just trying to reach a redshift of 9, about 550 million years after the Big Bang. But the new discovery blew all that out of the water, surprising the team that found it, said study lead author Pascal Oesch of Yale. The way they did it was different than the old methods of using a standard light wave signature marker, with the spectrum measured precisely by ground telescope. Instead, the team looked beyond that bright line to a longer, but messier light wave spectrum, using what's considered a rougher tool, Illingworth said.

Competing astronomer Richard Ellis at the European Southern Observatory, who found the previous record far galaxy, was skeptical. He said the light signatures used by Oesch's teams are "noisier and harder to interpret" and may overlap with competing nearby stars or galaxies. And for GN-z11 to be that visible it would have to be three times brighter than typical galaxies, he said in an email. Oesch said the team made sure "this was as clean as possible a measurement" with little contamination. He said the technique they used is starting to become standard. But Oesch, Brammer and Illingworth said don't expect new discoveries farther and older than this one, because they have pushed Hubble to its limit. Only when the next NASA space telescope is launched and operating, probably in 2019, will astronomers see farther. Astronomer Dimitar Sasselov at Harvard, who wasn't part of the research, called the discovery exciting and interesting: "Seeing and understanding the first galaxies and the first stars is an essential part of our origins story."

Amazing that we just realized there's another planet in our little solar system. And compared to our sun some other stars are much larger. It's so hard to comprehend how far away these other stars are.

I believe life existed on Mars billions of years before earth and same with venus.

And there's planets circling every star in the sky. Plenty of life out there

Isn't it a bit silly....10 billion years ago??

Where is the PROOF?!

Not in the bible.

Clearly you are a primitive species of human who doesn't understand science therefore you don't believe in it.

But you completely understand and believe your religion, right?

Isn't it a bit silly....10 billion years ago??

Where is the PROOF?!

It makes perfect sense if you understand how it works. Light takes time to travel like everything else. When looking at a galaxy that is 10 billion light years away the light you're seeing left that galaxy and traveled for 10 billion years before it reached your eyes, so what you're actually seeing is what that galaxy looked like 10 billion years ago.

Yea but how do they know it isn't just 2 or 40 light years away? Ive heard the answer before on the cosmos series but forgot. I'm no scientist but I don't disbelieve when I know it's all over my head.

Yes, I know, problem is of course that the velocity of light isn't a constant at all.

It is rather hilarious if I see figures like that.

How people can be so sure about these things is beyond me.

They've even figured that out.

Of course they could be wrong but based on the information gathered, it's the scientific consensus.

My dad makes the same ignorant arguments for why there must be a God. How do we know the earth is older than 10,000 years of he says. Was anyone there to see it?

Yet he'll believe the stories about vigin births and impossible flood stories?

really? How do you know? Or do you only BELIVE it?

consensus isn't right by definition at all, of course. truth is.

Hmm let's see.
ignorant =, which is an ad hominem, not a real good solid argument.

"Must be a God"???
where idid I mention that?

"was anyone there to see it??? " Where the hell did I ask that question?

Yet he'll believe the stories about vigin births and impossible flood stories?

So, I don't! so, what has that to do with me?

A lof of bollocks just passed.

Bible? I reject the Bible and it's pagan religions.

Yea but like most things in highschool it wasn’t important then or now so I forgot what isn’t important to me. I made my company $400k profit in 2017. How did not knowing this shit you teach in highschool hurt me?
