How far does Hubble see?

This diagram shows how Hubble has revolutionised the study of the distant, early Universe. Before Hubble was launched, ground-based telescopes were able to observe up to a redshift of around 1, about half way back through cosmic history. Hubble’s latest instrument, Wide Field Camera 3 has identified a candidate galaxy at a redshift of 10 — around 96 per cent of the way back to the Big Bang. The forthcoming NASA/ESA/CSA James Webb Space Telescope will see further still.

NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.

1. K&R...

Whatever the budget is for the James Webb Space Telescope, it's money well spent.

2. We are familiar with what fundies would say about this...

...but I have heard several times from some people unsolicited statements that know one knows what NASA spends it's money on "and no one ever will". Seems the RW talking points about NASA paints the agency as some financial black hole with zero accountability that somehow threatens our freedom, as if NASA were the Pentagon. NASA is living science and a wonderful inspiration to students with a thirst for knowledge so I can understand why it is a target of the corporatists but the credulity of some is disheartening.

5. Fundies are pissed that Hubble hasn't seen God sitting

on his throne in Heaven yet.

3. Awesome! Thanks so much for this post!

I am one of those whose brains get fuzzed by numbers but who respond very well to diagrams. This one is especially welcome because I had NOT grasped the incredible advance that Hubble represents. I knew of it--I'm even a Galaxy Zoo participant--but hadn't really taken it in. THIS is why we are often looking at little squirms of blue fuzz, still trying to form an "S," instead of developed spiral galaxies, in the Hubble photos. I knew they were far away and far back in time. I had no idea--no good visualizable idea--of HOW far.

6. You're welcome.

When I saw this on Flickr - I thought, well that explains a lot and had to share.
