Oh honey, because radio telescopes are too busy sifting through the cosmic noise like they're searching for a needle in a haystack. They need to point at specific locations in the sky to filter out all that unwanted interference and focus on those potential alien signals. So basically, they ain't got time to be casually stargazing, they've got work to do.
What else can I help you with?
Why are most large telescopes reflectors instead of refractors?
Most large telescopes are reflectors instead of refractors because reflectors are better at gathering and focusing light, allowing for clearer and more detailed images of distant objects in space. Reflectors also do not suffer from chromatic aberration, a common issue with refractors that can distort images.
Why are most large telescopes reflectors and not refractors?
Most large telescopes are reflectors because they can be made with larger apertures and are less affected by chromatic aberration compared to refractors. Reflectors also allow for easier mounting of additional instruments and have better light-gathering capabilities.
What are eyepiece lenses called?
Eyepiece lenses are commonly referred to as "ocular lenses" or simply "oculars." They are the lenses through which the observer looks in optical devices like microscopes and telescopes, providing magnification and focusing the image for viewing. Different types of eyepieces can vary in design, magnification power, and field of view.
By simply looking at the sky at night Can you pick out stars that are hotter then the sun Cooler than the sun What do you look for Is the star brightness a clue?
Generally the red stars are colder, the blue stars are hotter.Apparent brightness has nothing to do with this. A bright-looking star may simply be nearer to Earth. It may also have a large surface area.Generally the red stars are colder, the blue stars are hotter.Apparent brightness has nothing to do with this.

What is the best telescope in the world and why is it considered superior to others?
The best telescope in the world is generally considered to be the Hubble Space Telescope. It is superior to others because it orbits above Earth's atmosphere, which eliminates distortion caused by atmospheric conditions. This allows Hubble to capture incredibly clear and detailed images of distant galaxies, stars, and other celestial objects.
Are radio telescopes radioactive?
No - radio telescopes are (to put it simply) giant aerials. They gather radio signals from outer space, bringing them to a focal point. The signals are sent to computers for analysis.
Why is the HST better than previous telescopes?
Simply because the HST is in space - it doesn't get affected by the Earth's atmosphere or light pollution - as ground-based telescopes do. Therefore the images it produces are much more detailed.
Why can telescopes only see some parts of the electromagnetic spectrum?
Simply because there is a small magnet inside that is only powerfull enough to see some parts.
Is telescopes a collective noun?
No, "telescopes" is not a collective noun; it is a plural noun that refers to multiple individual telescopes. A collective noun represents a group of individuals or things as a single entity, such as "team" or "flock." In contrast, "telescopes" simply denotes more than one telescope without implying a single unit.
Can you use a mirror for a telescopes?
No you cannot. a mirror simply reflects light. you would have to have many mirrors no no
Why is the cat looking at the wall?
The cat may be looking at the wall due to curiosity, a potential threat, or simply because it caught its attention.
Why are stars not been found during the day time?
Simply because the daylight totally masks the far fainter star-light. They are still there, and radio telescopes can still track stellar radio sources.
Radio telescopes have poor resolving power because?
"Poor" is really a woosy adjective. If you're willing to express the size of the objective mirror in terms of wavelengths instead of inches or meters or yards, then a radio telescope and an optical telescope with equal diameters have equal resolving powers. The familiar difference in their dimensions is simply the obvious consequence of the difference in the wavelength of the signals they happen to be looking at. The shortest radio waves are something like 2,000 times as long as the longest light waves.
Why are reflecting and fefracting telescopes classified as optical telescopes?
"Optical" simply means that they work with visible light - as opposed to other EM radiation (radio waves, x-rays, etc.); gravitational waves; etc.
How drive is shared simply by looking at its icon?

7 What term is used to describe the transformation of analog signals into digital signals?
Transforming analog signals to digital is known simply as analog to digital conversion, sometimes shortened to A-D conversion.
How can I find out about New Jersey Bell Telephone Company Debentures?
By simply looking it up on google, not here because its simple.
