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.

∙ 13y agoViewing the universe in other spectrums allows us to learn more about the universe than we could with visible light alone. It is especially useful for detecting and studying objects that do not emit visible light (or emit very little visible light) such as Nebulae.

∙ 14y agobecause all other wavelengths of light are blocked by the dust between here and there..
infrared penetrates dust quite readily.

How do telescopes and the electromagnetic spectrum work together to help us explore space?
Telescopes are used to observe and magnify images in outer space. The electromagnetic spectrum consists of many wavelengths, which constitute visible light, infrared, microwave, and X-ray radiation. Telescopes can be manufactured to view these certain types of radiation.
Do astronomers sleep during the day?
If they have been observing at night, yes - rather like shift workers. However most astronomers no longer observe directly but use cameras that are much more sensitive than the human eye to obtain their telescope data. This allows telescopes to be automated and the data save so that astronomers can analyse it during the day without having to visit the telescope. These astronomers work normal hours and only a few are needed to man the telescopes (a task which may also be done remotely).
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
What do astronomers do?
Astronomers use the principles of physics, chemistry, and mathematics to learn about the fundamental nature of the universe, including the sun, moon, planets, stars, and galaxies. As such, astronomy is sometimes considered a subfield of physics. They also apply their knowledge to solve problems in navigation, space flight, and satellite communications and to develop the instrumentation and techniques used to observe and collect astronomical data.Almost all astronomers do research. Most of them also have teaching as part of their work, usually in a university.Some are theoreticians, working on the laws governing the structure and evolution of astronomical objects. Others analyze large quantities of data gathered by observatories and satellites and write scientific papers or reports on their findings. Some astronomers actually operate large space-based or ground-based telescopes, usually as part of a team. However, astronomers may spend only a few weeks each year making observations with optical telescopes, radio telescopes, and other instruments.A small number of astronomers work in museums housing planetariums. These astronomers develop and revise programs presented to the public and may direct planetarium operations.Work environment. Most astronomers do not encounter unusual hazards in their work. Astronomers who make observations with ground-based telescopes may spend many hours working in observatories. This work usually involves travel to remote locations and may require working at night. Astronomers whose work depends on grant money may spend a lot of time writing grant proposals to keep their work funded.Astronomers may need to work at odd hours to observe celestial phenomena, particularly those working with ground-based telescopes.
What is the technology used to observe the solar system?
Telescopes, Pictures,Satellites, and Probes
Explain how astronomers use electromagnetic radiation to study space?
Electromagnetic radiation is "light." Light in various wavelengths (gamma rays through to infrared) comes to us from out in space, and astronomers use instruments called telescopes to capture it and observe the bodies and processes emitting this light.
What type of telescope does not use optics?
Telescopes can be made to see in almost any part of the electromagnetic spectrum: visible light, infrared light, ultraviolet light, X-rays, or radio waves. The largest telescopes are those for radio waves - in Arecibo there is one with a diameter of 300 meters. I am not sure whether it is the largest, though.

What technologies are used to observe planets?
they use telescopes gosh you people are stupid
Why do astronomers move their telescopes when observing the sky?
To compensate for the motion of the Earth in order to observe a fixed object, such as a distant star. Relative to the Earth, distant objects do not move, but the Earth rotates and orbits the sun, thus all objects appear to move relative to a fixed point on the Earth. Therefore telescopes (which are fixed points) must move to compensate for this motion.
