"Web9. júl 2024 · When a galaxy recedes from us, the light we see from it is redshifted. For galaxies at cosmological distances, this redshift is fundamentally different from a Doppler shift; whereas the latter is due to a velocity difference between the emitter and the receiver, a cosmological redshift is due to photons traveling through an expanding space $^\dagger$.

WebIt starts out at this frequency. And it gets shifted towards the red end of the spectrum, which is towards the right for Galaxy A, by a small amount. In other words, the spectral line is redshifted. Therefore, the galaxy emitting the spectrum must be moving away from Earth. And so we know that Galaxy A is moving away from Earth. WebThis legacy reflects the work of the telescope’s namesake, renowned 20th century astronomer Edwin Powell Hubble. Like the Hubble Space Telescope, Edwin Hubble’s discoveries transformed the frontier of scientific knowledge. His work took us beyond the Milky Way and placed us in an ever-expanding universe with a myriad of galaxies beyond …

Web3. mar 2016 · When astronomers observe distant galaxies, the entire spectrum is redshifted, so all features appear at a wavelength redder than would be expected. The ultraviolet drop is such a dramatic feature that it can be readily identified and used to obtain the redshift of a galaxy, and therefore its distance.
