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.

WHICH TELESCOPE CAN SEE IMAGES OF OBJECT THROUGH RADIATION?
Telescopes that can see images of objects through radiation include radio telescopes and infrared telescopes. Radio telescopes detect radio waves emitted by celestial objects, allowing astronomers to study phenomena like pulsars and cosmic microwave background radiation. Infrared telescopes capture infrared radiation, which is useful for observing cooler objects in space, such as dust clouds and distant galaxies. Both types of telescopes provide valuable insights into the universe beyond visible light.
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
What does optical power mean?
Optical power refers to the ability of a lens or optical system to converge or diverge light. It is typically measured in diopters (D) and indicates the strength of the lens in focusing light onto the retina. Positive optical power converges light (useful for correcting hyperopia), while negative optical power diverges light (useful for correcting myopia).
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.

What is the significance of an optical system with an infinite focal length?
An optical system with an infinite focal length is significant because it produces parallel rays of light, which can be useful in applications such as telescopes and cameras for capturing distant objects with clarity and precision.
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
Why are infrared sensors more useful at night?

What are the unique optical properties and applications of a positive meniscus lens?
A positive meniscus lens has a curved shape that causes light to converge, making it useful for focusing and magnifying images. Its unique optical properties include reducing spherical aberration and increasing depth of field. Applications of a positive meniscus lens include camera lenses, microscopes, and telescopes.
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.
What lens is thick in the middle and thin at the edge?
A converging lens or a convex lens is thick in the middle and thin at the edges. It causes light rays to converge at a focal point, which makes it useful for focusing light in optical systems like cameras and telescopes.
What does optical power mean?
