What are two ways the atmosphere limits what astronomers can detect?
Atmospheric absorption: Certain wavelengths of light can be absorbed by gases in the Earth's atmosphere, making it difficult for astronomers to detect celestial objects at those specific wavelengths. Atmospheric turbulence: Turbulence in the atmosphere can cause distortions in the images obtained by telescopes, affecting the resolution and clarity of astronomical observations.
How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
Why must astronomers use sateltiles and earth orbiting observations to study the heavens at x-ray wavelengths?
Electromagnetic radiation with wavelength shorter than ultraviolet -- including x-rays -- is strongly absorbed by earth's atmosphere. X-ray detectors looking into space from the surface of the earth don't see anything, because no x-rays reach the surface ... the main reason that all life on earth has not been broiled yet by E&M radiation from space.
How would earth appear at radio wavelengths to extraterrestrial astronomers?
Earth would appear as a bright source of radio waves to extraterrestrial astronomers due to human-made radio transmissions. These transmissions, including radio broadcasts, satellite communications, and radar signals, create a radio "glow" around Earth that can be detected from great distances in space.
What is solar blind?
Solar blind refers to a range of ultraviolet (UV) wavelengths that are absorbed by the Earth's atmosphere, making it difficult for these wavelengths to reach the Earth's surface. This provides protection from harmful UV radiation, particularly for living organisms. Solar blind detectors and filters are often used to selectively detect or block UV radiation within this range.

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.

Indian astronomers recognized that earth?
India astronomers recognized that the earth was a sphere.
Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.
How light allow you to detect color?
Light contains different wavelengths, and when it interacts with an object, certain wavelengths are absorbed and others are reflected. The reflected wavelengths determine the color that we see. Our eyes contain color receptors that detect these wavelengths and send signals to the brain, allowing us to interpret the color of an object.
What did ancient astronomers know about the earth?
Ancient Greeks such as Aristotle recognized that Earth and the Moon are spheres, and understood the phases of the Moon, but because of their inability to detect stellar parallax, they rejected the idea that Earth moves. Eratosthenes measured the size of Earth with surprising precision.
How do astronomers use evidence to detect black holes?
Astronomers use evidence such as the behavior of nearby stars and gas, as well as the bending of light around invisible objects, to detect the presence of black holes in space.
Why are there diiferent telescopes in space?
To detect different wavelengths of the electromagnetic spectrum.
Why is nebula difficult to detect?
Nebulae can be difficult to detect due to their vast distances from Earth and their often faint luminosity. Many nebulae are composed of diffuse gas and dust, which can obscure them from view, especially if they are located within the plane of the Milky Way. Additionally, some nebulae emit only in specific wavelengths, such as infrared or radio, requiring specialized instruments to observe them effectively. This combination of factors makes identifying and studying nebulae a challenging task for astronomers.
Which wavelength of radiation do astronomers use to detect these hottest stars in our galaxy?
infrared
Which wave can your eye detect?
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
