2 Amazing Pictures from the Hubble

Post by **Airconvent** » Mon Oct 30, 2006 10:38 pm

Imagine that...the Hubble Space telescope on 2 occasions opened its aperture and took 2 shots of 10-day and 11-day exposures respectively pointing at a completely blank part of the sky.
This is what it saw...10,000 galaxies appeared on the image!

Hi,
Yap... saw that image quite long ago. You can search the web and download that image... Full Size: 61MB for JPEG and 110MB for TIFF

Anyway, a very nice and interesting video.

Have a nice day.

Yup.. we are real real small compared to the size of the universe and that makes astronomy a hobby that is interesting.

Thanks for sharing this. Although I have known this for quite a long time, this is the first video of this I have seen.

Should've taken a 100-day exposure instead.

a 100 day exposure?! that would be a magical feat i think. No, actually i think it's undoable. over 100 days, the Earth moves rougly 1/4 of an orbit, which is 90deg. you can't keep the HST at the same position for 100 days over an orbit of 90deg, and the mathematics needed to compensate for the angle change in exposures will be erm, unthinkable...

Am I making sense? or maybe there's some high level mathematics or physics that can overcome the problems.. Of course i know, we're just joking about 100days.

I hope this isn't going OT ^^||

May I know how to learn more about the maths and physics applied in Astronomy?

Don't forget that the Hubble is a VERY VERY VERY expensive and life limited equipment and many scientists, each with their own agenda, fights hard to get a slot to use it. its a feat that the photographers managed to hog the scope for 10 days to do what is scientifically of no value although the social value is tremendous...
