A redshift is a shift in the frequency of an electromagnetic wave caused by an object’s motion. Light from objects moving away from an observer have their light waves shifted toward the red part of the spectrum. Redshift is commonly observed inastronomy, particularly in the observation of ve...
other terms are more technical and may sound "jargony" to people who don't know a lot about astronomy. Two such terms are "redshift" and "blueshift."They're used to describe an object's motion toward or

What is redshift? Define a ray of light. Explain the difference between intensity and solar constant. What is the evidence that light is energy? What the speed of the dark? What is meant by the polarization of light? What is a spectrum ?
Jason Steffens is an assistant professor of physics and astronomy at the University of Nevada, Las Vegas. What does cosmological redshift do to light? The cosmological redshift is a consequence of the expansion of space. The expansion of space stretches the wavelengths of the light that is trav...
What is ephemeris in astronomy? What is responsible for the earth's elliptical orbit around the sun? What model of universe creation is supported by redshift? What shape is the universe? What shape is the solar system? Which of the terrestrial planets is closest to the Sun?
Astronomy is the scientific study of all objects in space. The word comes to us from the ancient Greek term for "star law." Astrophysics, which is part ofastronomy, goes a step further and applies thelaws of physicsto help us understand the origins of the universe and the objects in it...
Gravitational redshift Theelectromagnetic radiationof an object is stretched out slightlyinside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are ...

I think you'll agree that one of the biggest problems in learning science is that science is a completely different language. If you go into medicine, there's a whole different English language you need to learn. If you enter the world of astronomy, it's the same thing - that can obvi...
