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 are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
What are telescopes for invisible EMR?
Telescopes for invisible electromagnetic radiation (EMR) are specialized instruments designed to observe wavelengths outside the visible spectrum, such as radio, infrared, ultraviolet, X-rays, and gamma rays. These telescopes utilize various technologies, such as radio antennas or specialized detectors, to capture and analyze the corresponding EMR. By studying these wavelengths, astronomers can gather crucial information about celestial objects, their composition, temperature, and movements, which are not visible to the naked eye. Examples include radio telescopes, infrared observatories, and X-ray space telescopes.
Are telescopes and microscopes used by astronomers?
Telescopes are commonly used by astronomers to observe objects in space such as planets, stars, and galaxies. Microscopes are not typically used by astronomers as they are designed for studying very small objects on Earth, such as cells and microbes.
What is long-wave electromagnetic radiations used in special telescopes?
Long-wave electromagnetic radiation used in special telescopes includes infrared radiation and submillimeter radiation. These telescopes are designed to detect and study objects that emit or reflect these longer wavelengths of light, allowing astronomers to observe phenomena such as cool stars, cosmic dust, and molecular clouds.
What kinds of telescopes are used to see stars in visible light?
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.

Why do astronomers find it difficult to locate extrasolar planets with telephones?
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
Who studies the stars moons and planets?
Astronomers study stars, moons, and planets. They observe, analyze, and interpret data gathered from telescopes and other instruments to learn more about the universe.
What kinds of telescopes are used to see stars in visible light?
Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.
What is best way to study young stars hidden behind interstellar dust clouds?
One effective way to study young stars hidden behind interstellar dust clouds is by using infrared telescopes. Infrared light can penetrate dust clouds more easily than visible light, allowing astronomers to observe these young stars more clearly. Additionally, combining data from multiple telescopes and techniques, such as radio astronomy, can provide a more complete picture of these hidden stars.
Why aren't infrared telescopes built at low altitudes?
Infrared telescopes are usually built at high altitudes to minimize atmospheric interference. At lower altitudes, the Earth's atmosphere absorbs and scatters infrared light, making it difficult to observe astronomical objects accurately. By placing telescopes at high altitudes, such as on mountain peaks, scientists can minimize the interference and obtain clearer observations of infrared radiation from space.
How does studying the infrared rays aid astronomers?
Studying infrared rays helps astronomers to observe cooler objects in space that are not visible in other wavelengths, such as dust clouds and young stars. It also provides insights into the composition, temperature, and structure of celestial objects, helping astronomers to better understand the universe's mechanics and evolution.
Do astronomers use ground-based X-ray telescopes?
Yes, astronomers use ground-based X-ray telescopes to study high-energy phenomena in space. These telescopes are typically located at high-altitude sites to reduce interference from Earth's atmosphere and are used to observe sources such as black holes, neutron stars, and supernova remnants.
What kind of scientist uses telescopes to study space?
An astronomer uses telescopes to study space. They observe celestial objects like stars, planets, galaxies, and other phenomena to understand the universe's properties and behavior.
How do astronomers detect objects in space?
Astronomers use a variety of methods to detect objects in space, including telescopes that observe different wavelengths of light (such as visible, infrared, and radio waves), sensors that detect particles like cosmic rays and neutrinos, and gravitational wave detectors. They analyze the data collected from these observations to identify objects like stars, planets, galaxies, black holes, and more.
