Telescope Buying Guide

Nooone asked:


The diameter of the Hubble Space Telescope is 2.4 meters; the diameter of the new Chilean telescope is 9.6 meters.

How many times better is the theoretical resolution of the new Chilean telescope (the best possible resolution that the Chilean telescope could achieve if nothing else outside of the telescope itself acted to make the resolution worse) compared to the theoretical resolution of the Hubble Space Telescope? Again, show your work or explain your reasoning.

Somebody. asked:


If the Hubble Space Telescope can see trillions of miles to other galaxies then why do we need a satellite to go past Pluto and such?? Wouldn’t we just look everywhere with the Telescope???
I need to read up on it !!

Maybe it’s located so far away that we send other satellites to look in our solar system??

Thanks for the link, I’ll be educating myself !!

yap_3210 asked:


Is the Hubble or Kepler Space Telescope more powerful? And by how many times more powerful? Does the Kepler telescope detect visible light or rays of other wavelengths? Can it be considered as Hubble’s successor?

Who is the Hubble telescope named after and what does he do in a Living?
