Great slidei show and I too am looking forward to learning more about "what's inside."

As a passive observer of astronomy I may have been missing something all along.  That is, these images are almost as much art as they are science.  In other words, what these massive, dedicated sensors detect is energy of varying intensity in a specific slice of the spectrum - Infrared, X-Ray, UV, etc..  But its nothing the naked eye would see if we were capable of laying eyes on the actual event "billions and billions" of light years away.  That's where they artestry comes in, i.e. coloring this wavelength red, and that wavelength green, and that other one purple etc. allows us to imagine what it would look like somwhere in a galaxy far, far away.  But we don't really know if that supernova is really that beautiful, do we?

Should I feel deceived?  Am I missing something?  May the Schwartz be with the best answerer.

Systems go into these scopes. Looking forward to some posts that talk more about the advanced algorithms and systems that process them...

Limitations imposed by speed evident even with telescopes

Great article. Adaptive optics, for earth-based telescopes, were and are a real game changer.

Funny thing is, even using telescopes, our investigations of space are hopelessly limited by speed. In this case, the speed of light. The further out we look, the more what we see has come and gone eons ago.

So yes, using telescopes is a great way of seeing how the universe formed, and of investigating the more or less current status of the very closest star systems, but we're still in this speed straightjacket.

We need that warp drive and those subspace communications channels. Someday in the future, people will wonder how we could be so primitive and limited, with such a compromised view of reality, back in the 21st Century. (Well, early 21st Century anyway. There's hope for the 21st Century yet!)

Thanks eBum. Good call. We're saving those for the next top 10 telescopes article! It's arbitrary to stop at ten but since that was the goal, Nathan had to stop somewhere.

Great story, Nathan. Thanks.

If you're going to count LSST, you may as well count the Thirty Meter Telescope or the Daniel K Inouye Solar Telescope.  All are not operational yet, but in planning or construction.  If you're looking at operational telescopes, you forgot Pan-STARRS, with the largest astronomical cameras in the world.

Good article.  Amazing how adaptive optics can do so much. Thanks.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
