Current millimeter telescopes can only just detect the most luminous sources, giving us tantalizing first glimpses of the epoch of galaxy formation. A very large millimeter telescope is now required to explore these new horizons, one with both high sensitivity and angular resolution - The Atacama ...
Why does a larger telescope allow astronomers to see more? Why does Venus have no moons? Why are many large optical telescope located on mountaintops? Why is radio astronomy important? Why are there no stars on pictures of the man on the moon?
Why are concave mirrors used in telescopes?Reflecting Telescopes:Reflecting telescopes quickly replaced refracting telescopes for professional observatories as it became apparent that their mirror could be manufactured much larger than the lenses of refracting telescopes. This means that reflecting telescopes...
I understand--you are referring to good telescopes for beginners, not for yourself. I don't think a mount with setting circles is a good idea for a six to eight inch reflector for beginners. The mount will be big and heavy, whether with or without encoders, push-to, or go-to. At ...
In this way, logic is like a telescope, but opens up a universe of facts that even telescopes cannot reach. But why do we need something like logic to let us do this? Of course logic does not literally let us see things we otherwise couldn't see, as a telescope does. The ancient ...
Any optical system (telescope) has a finite resolution and even the nearest stars are still registered as points, afaik. The advantages of a larger aperture are twofold - firstly, the light gathering is much greater so you can see fainter objects and secondly, the larger the aperture, the be...
The first optical telescopes used two lenses to focus the light coming into the aperture. The larger the aperture and the longer the telescope, the more light that could be focused.Answer and Explanation: The optical telescope was essentially invented to see things that were far away. The ...
First, of all, groups are rather small objects, and only the nearest ones are angularly large; this is why single-dish radio telescopes are almost never used to study them. Interferometers can be more useful here; however, what one is searching for is extended, rather weak structures. In ...
