However, in some cases, galaxies may approach one another and interact. When two or more galaxies move too close to each other, they begin to merge in one of the most violent and spectacular events in the cosmos.
Web1 aug. 2013 · Here's how the Doppler effect works: When a noisy object is moving toward you, its sound waves bunch up, producing a higher frequency, or pitch. Conversely, as soon as the object is moving away from you, the sound waves stretch out, and the pitch lowers. The faster the object, the greater the pitch change. The Doppler effect occurs for light as ... Web25 apr. 2024 · The new estimate of the Hubble constant is 74 kilometers (46 miles) per second per megaparsec.

It’s worth taking a quick detour to talk about how long it takes the Solar System to move around the center of the galaxy. WebWhen two galaxies of the same size are merging, many new stars form, making the merging galaxies brighter. However, if these galaxies merge too quickly, many of the newly formed stars are likely to die shortly after their formation. As they begin to approach one another, the galaxies begin to stretch and deform, creating tails or arms.
