This review is from: Observational Astrophysics (Astronomy and Astrophysics Library) (Hardcover)
Astronomy is going through exciting times, as new and better instrumentation and methods gives us greater insight into the universe. This book helps explain what some of the advances are. It gives basic material about radiation, photometry and the like. There is an important explanation of how the atmosphere has traditionally limited the resolution of images (at least in the visible spectrum) due to turbulence. Which leads the book into some of the attractions of space-based telescopes.
But the book also goes into how ground based telescopes are overcoming the atmospheric barrier. Using adaptive optics in "smart" telescopes. This lets them cancel out the effects of turbulence, on the time scale of that turbulence. Very impressive. We can push to the instrinsic limits of the optics. The book takes you to the frontiers of modern astronomy. |
