Why are infrared telescopes sometimes more useful than optical telescopes?

A telescope that "sees" in the infrared spectrum sees heat, which with its longer wavelength than regular visible light has an easier time passing through gas and dust and can therefore see details in areas that are blocked from view. It can also see objects that are warm, but not warm enough to emit light by glowing.

What are the instrument used to study stars and other heavenly bodies?
Telescopes are the main instruments. There are many different types, such as radio telescopes, besides the "usual" optical telescopes. Other instruments such as spectrometers are very useful too.

Why are telescopes very useful to scientist?
They are very useful to scientists because it helps them see stars and planets better
Why must astronomers use infrared telescopes to observe the motions of stars around Sgr A?
Studying universe in IR (infrared) wavelength is called infrared astronomy. Because of lot's of parameters such as redshift (for far objects like early galaxies) it is very interesting for modern astronomy and most of future studying in this field will be on these wavelengths. Next generation of space telescopes (like WEBB) will observe in IR too.
Why telescopes that detect non optical radiation are useful for studying objects in space?
Visible light is a very narrow range of the electromagnetic spectrum. Even audible sound, at the very bottom, is part of this EM spectrum. Radio and other types of 'scopes are designed to 'see' these other ranges, often with surprising results. The space telescope employs more than visible light capabilities, as do many Earth and space-bound telescopes. Looking at Saturn in visible light is quite breath-taking, but in ultra-violet (UV) a remarkable geometric pattern is visible on one of its poles.

What are the uses of convex lenses in optical instruments?
They're caved-outward shape allows the focused object to appear backward or upside down. They also magnify various objects, which is useful for magnifying glasses and telescopes.
Why are infrared sensors useful at night?
Infrared is heat and during the day other objects are hot besides bodies

Do astronomers spend all their time looking through a telescope and recording their results?
Nowadays, the bulk of the work astronomers do is on computers. They spend a small portion of their time at telescopes actually taking data. Astronomically-useful telescopes rarely have eyepieces you can look through. Radio, ultraviolet, or infrared telescopes collect light that you can't even see with your eye! Telescopes that collect visible light often have electronic cameras called CCD cameras that create an image in a computer. Many telescopes are used to create a spectrum (the light is split into a rainbow, and the brightness of each color is measured). Radio telescopes record signals that astronomers can reconstruct using a computer to make an image or a spectrum.

What is the scope in computer hardware networking?
It varies from computer to computer.. It's sometimes infrared and sometimes iron sight.

Did zacharias janssen have an education?
He did a lot of important work with microscopes and telescopes, as well as forging money, so he certainly had an education. He may have educated himself, of course, which is sometimes more useful than going to school.
How do optical tweezers work?
Optical Tweezers can only be useful on individual atoms. What they are is steerable beams of light used to move atoms around.
