Meanwhile, the shorter wavelengths measure extremely energetic phenomena. Astronomers use the entire electromagnetic spectrum to observe a variety of things. ... By using large infrared telescopes, astronomers have been able to peer through the dust lanes of the Milky Way into the core of our galaxy.

By using large infrared telescopes, astronomers have been able to peer through the dust lanes of the Milky Way into the core of our galaxy. The majority of starsemit most of their electromagnetic energy as visible light, the tiny portion of the spectrum to which our eyes are sensitive.

A blueshift is any decrease in wavelength, with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as redshift. In visible light, this shifts the color from the red end of the spectrum to the blue end.

In physics, redshift happens when light or other electromagnetic radiation from an object undergoes an increase in wavelength. "Redshifting" does not mean that the light is actually red, or actually becomes red.

Our Sun is a bright, hot ball of hydrogen and helium at the center of our solar system. It is 864,000 miles (1,392,000 km) in diameter, which makes it 109 times wider than Earth.Aug 15, 2018

Our Protective Atmosphere. Our Sun is a source of energy across the full spectrum, and itselectromagnetic radiation bombards our atmosphere constantly. However, the Earth's atmosphere protectsus from exposure to a range of higher energy wavesthat can be harmful to life.

Radiation from the Sun. [/caption]Radiation from the Sun, which is more popularly known as sunlight, is a mixture ofelectromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum.Mar 19, 2010

The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars.

Astronomers use telescopes to see objects at wavelengths all across the electromagnetic spectrum. Some very hot stars emit light primarily at ultraviolet wavelengths. There are extremely hot objects that emit X-rays and even gamma rays. Some very cool stars shine mostly in the infrared lightwavelengths

This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave. The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical,ultraviolet, X-rays, and gamma-rays.

Electromagnetic spectrum is the range of wavelengths or frequencies over which electromagnetic radiation extends.
