When the ultraviolet light from hot stars in very distant galaxies finally reaches us it arrives at Earth in the form of?
When the ultraviolet light from hot stars in very distant galaxies finally reaches us, it arrives at Earth in the form of lower-energy wavelengths due to the expansion of the universe. This phenomenon, known as redshift, occurs as the universe expands, stretching the light waves and shifting them toward the red end of the spectrum. As a result, much of the ultraviolet light is observed as visible light or even infrared radiation when it reaches our telescopes. Thus, we can study these distant stars using various wavelengths of light that have been transformed during their journey across the cosmos.
The visible part of distant galaxies is the galaxies'?
The visible part of distant galaxies is the collection of stars, gas, and dust within the galaxy. These components emit light that reaches our telescopes, allowing us to observe and study the structure and properties of the galaxies.
Are quasars part of your solar system?
No, quasars are not part of the solar system. Quasars are extremely distant and energetic objects located in the far reaches of the universe, millions or billions of light years away from our solar system. They are powered by supermassive black holes at the centers of galaxies.
How the expansion of space could cause a red shift in the light from distant galaxies?
The expansion of space causes a redshift in the light from distant galaxies due to the stretching of wavelengths as the universe expands. As light travels through expanding space, its wavelength increases, shifting it toward the red end of the spectrum. This phenomenon, known as cosmological redshift, occurs because the space between galaxies is increasing, leading to longer wavelengths by the time the light reaches us. Consequently, more distant galaxies appear redder, providing evidence for the expansion of the universe.
What were the names of the galaxies that collided on 08162011?
If any galaxies actually collided on August 16, 2011, we won't know about it for some unknown number of millions of years, as the light of the collision reaches us. If we have just today observed that two distant galaxies appear to be colliding, then they collided some number of millions of years AGO, and the light of the event has just reached us.
What are three types of energy that reaches the earth's atomosphere?
Ultraviolet Types
What makes the sea of stars glow in the night sky?
The sea of stars glows in the night sky due to the light emitted by distant stars and galaxies. This light travels through space and reaches our eyes, creating the beautiful spectacle we see in the night sky.
What reaction occurs when ultraviolet radiation from the sun reaches the earth's atmosphere?
When UV reaches earth, it interacts with ozone. It both creates and depletes ozone.
Most of the Sun's ultraviolet light reaches the Earth's surface?
No, most of the Sun's ultraviolet light is absorbed by the Earth's atmosphere, particularly by the ozone layer. Only a small fraction of ultraviolet light reaches the Earth's surface, which is why it is important to protect ourselves from its harmful effects with sunscreen and protective clothing.
What does the ozone layer do to ultraviolet layer?
The ozone depletion is increasing the amount of UV radiation that reaches the earth....
Do you really look in to the past when you look through a telescope at galexes light years away. why?
Yes it is true. we actually look in the past when looking at distant galaxies. It is because the light emitted by the billions of stars in the galaxies take thousands of millions of years to reach our eyes. So whatever we are looking in the sky has taken place in past. What is happening in the present, we will only know after the light emitted from the object reaches our eyes.
Is ultraviolet radiation the energy emitted by earth?
No, ultraviolet radiation is not emitted by the Earth itself. Ultraviolet radiation comes from the sun and is a form of electromagnetic radiation with shorter wavelengths than visible light. Earth's atmosphere filters and absorbs some of the incoming ultraviolet radiation before it reaches the surface.
