I didn’t think that it would be possible so soon. Wow, and here to say we worked so hard on the Hubble. The Hubble telescope was N.A.S.A.’s greatest projects and China, is to believe, created something more advanced. But, did China actually do it? Is there a telescope more advanced then the Hubble?

Several ground-based telescopes are more powerful than the Hubble. The Hubble’s advantage is that it’s in space, away from the Earth’s atmosphere which causes distortions and blurring.

No, I’m not aware of any Chinese telescope more advanced or more powerful than the Hubble. Any chance of you telling us where you heard that? Or did you just make it up?

Learn how batteries store the energy needed to keep the Hubble powered when it is in orbit at night and how solar panels help keep it powered when it orbits in the light. Demonstrations using graphs and mathematical equations help explain what it takes to keep the Hubble powered while in orbit around the Earth.

I’m taking a new position at the Space Telescope Science Institute and I start Monday so I’ve been spending the last two weeks getting ready to move out to Baltimore. I should be set up and ready to go again with new vids sometime late next week.

Also, if you’re interested in following a space nerd doing his space thing, I set up a twitter account here:

http://twitter.com/TonuDarnell

Feel free to follow this (or not!). I’ll try to post updates on things there if enough people think it’ll be interesting.

There’s also a Facebook page, but since it is so scarily easy to find me on that thing, I’ll let you do the detective work (such as it is) to find me.

A few years ago this question would have been correct for the very simple reason that in space the Earth’s atmosphere is not present, and can therefore observe objects in space with no atmospheric disturbances. This was the original reason why space telescopes were built and placed into orbit.

However in the past few years there have been telescopes designed on Earth that can actually resolve images even better than the Hubble. The reason for this is adaptive optics. Adaptive optics can filter out the disturbances an image has due to the atmosphere and show as if it were taken from space. Many telescopes on Earth can now resolve images better than the Hubble, and soon there will be one in place called the E-ELT, which will be able to observe galaxies from the furthest reaches of the universe.
