What else can I help you with?
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
Did the earliest telescopes make things look thousand of times closer than they were?
Yes, the earliest telescopes made things look thousand of times closer than they were, and modern telescopes still do that.
What is the telescopes special uses?
To look at things in the sky\
Why is it a advantage for reflecting and refracting telescopes to be made larger?
The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
What instrument makes small things look larger?
Microscopes, telescopes, a magnifying glass, reading glasses, a concave mirror, a drop of water, a glass tube looked at from the side.
Why is it necessary to use different types of telescopes in astronomy?
Larger telescopes are often used to focus on one specific star or distant formations. Smaller telescopes view broader areas of stars or larger formations.
What instrument to look at the sun?
Solar telescopes are used by professional astronomers both on earth and on satellites. These instruments differ from other optical telescopes because they do not need to collect light and also must deal with the heat from the object they focus on. The telescopes are very large.
Why are optical space telescopes able to see deeper into outer space than land based optical telescopes?
Optical space telescopes are not affected by atmospheric turbulence, which can distort images and limit the clarity of ground-based telescopes. Additionally, they can be positioned above the Earth's atmosphere, avoiding interference from light pollution and atmospheric absorption. This allows them to capture clearer and more detailed images of distant objects in space.
Do optical telescopes allow us to study the visibal light radiated from stars?
Yes, optical telescopes are specifically designed to study visible light radiated from stars. They collect and focus visible light from stars to provide detailed images and spectra, allowing astronomers to analyze the properties of stars such as temperature, composition, and motion.
What type of things do scientist do?
They study all kinds of things or look through telescopes and look at the sky to see what's happening
How are telescopes and microscopes alike and different?
Telescopes and microscopes are both optical instruments that use lenses to magnify and observe objects. They differ in their primary function: telescopes are designed to view objects that are far away, like celestial bodies in space, while microscopes are designed to view objects that are very small, like cells or microorganisms. Additionally, telescopes typically have larger objective lenses or mirrors compared to microscopes.
How is the VLA similar to an optical telescope?
well,both telescopes let you look into the ground into the inner core and you see deep in he atmosphere which is space. Errr... The Very Large Array is an array of radio-telescopes, i.e. it detects radio emissions from stars and similar. An optical telescope as its name suggests, collects visible light. The similarity is that increasing the aperture increases the radiation-gathering power by a square-law. In an optical telescope this is achieved by a larger mirror (or lens but most large telescopes are reflecting.) The VLA uses a "synthetic aperture" to gain the advantages of increasing its gathering area without the cost and complexity of building a single, very large dish.
