In what ways are radio telescopes better than optical telescopes?
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
How can a nebula be observed from earth?
Nebulae can be observed from Earth using telescopes. Their gas and dust particles reflect and emit light, making them visible to astronomers. Different types of telescopes, such as optical, radio, and infrared telescopes, can be used to study various aspects of nebulae.
Can you study visible light using a radio telescope explain your answer?
No, a radio telescope is designed to detect radio waves, which have much longer wavelengths than visible light. Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.
Why can't astronomers study the central regions of the Milky Way Galaxy using optical visible-light telescopes?
That's because they wouldn't see anything. There is too much dust interfering with light in that region.
What are 3 basic categories of astronomical observation?
The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.
How do optical telescopes and radio telescopes gather info about stars?
using radio waves it collects the data.
How do get information about distant planets?
Send a probe or alalyse the light they reflect using optical telescopes.
How do scientist study invisible radiation from objects in space?
They study visible light by using optical telescopes.

What is optical astronomy?
The term optical telescope refers to telescopes that are used to make observations in the visible light spectrum, that the human eye can see. This is in comparison to such things as X ray telescopes, radio telescopes, etc., which are designed to make observations in parts of the electromagnetic spectrum that are invisible to the human eye.
When using telescopes other than optical telescopes why do you need to have false color maps to read the electromagnetic waves?
The colors we know really only correspond to specific wavelengths of visible light. When representing other electromagnetic waves, you can show the information without using color at all, arbitrarily assign certain wavelengths to certain colors, or convey some other information through the use of color.
How can a nebula be observed from earth?

Is it true or false that Astronomers on Earth are able to measure the rotation of Venus by using optical telescopes to watch surface markings as rotation carries them across the disk of Venus?
True
A refracting telescope produce an image using an?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
Can you study visible light using a radio telescope explain your answer?

Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.
How do we see deep into space?
We see deep into space by using optical or radio telescopes, either from the Earth's surface, from satellites orbiting above us, or carried out into space on an unmanned spacecraft.
What does a refracting telescope do and how does it differ from other types of telescopes?
Ah, a refracting telescope is a wonderful invention! It works by using a lens to bend or refract light, helping us see objects in the distance with more clarity. Unlike other types of telescopes, like reflectors or catadioptrics, refracting telescopes use lenses instead of mirrors to gather and focus light. Remember, there's no right or wrong choice when it comes to telescopes – each one has its unique beauty and purpose!
