what are the advantages and disadvantages of using radio telescopes and probes to search for life in the universe?
How are radio waves used to detect objects in space?
They are less expensive that actually sending astronauts.
They can detect elements that light telescopes can’t.
Radio waves indicate a lot of tel-tale things that may indicate the possibility of life on those other heavenly bodies.
Disadvantages:
We can’t be sure until we get there…or it gets here.
It’s a tricky and sometimes high-maintinance thing to keep these telescopes and/or probes up there doing there thing.
telescope that is better for viewing planets and stars. Meade Telestar 70,121 model or model DS-2114ats tc?
Well, not really. Single point if to Sagettarius, rich star fields and probably will be just as happy with any telescope on the subject. Planets are a different story. While the planets are bright and easy to detect, resolve details about them is perhaps one of the most difficult aspects of astronomy. You need to be able to use a powerful, and just see a blur. People who are serious observers world spend thousands of dollars in apochromatic refractors quite large, with long focal lengths. Most of us do not have this kind of money, however, and good views of the planets can have on large reflectors with long focal lengths. In addition, because it is using high magnification, you need good eye and a sturdy mounting. I can not say that none of these telescopes you're seeing are particularly sturdy we're talking about high-powered display so you can be disappointed. 4.5 "is the smaller telescope aperture and is still sought with goto (because it is a waste of money for small telescopes), invest the extra money on a telescope with more openness, as a 6 "or 8".
