Redshift of andromeda galaxy
In the widely accepted cosmological model based on general relativity, redshift is mainly a result of the expansion of space: this means that the farther away a galaxy is from us, the more the space has expanded in the time since the light left that galaxy, so the more the light has been stretched, the more … Zobraziť viac In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and … Zobraziť viac The spectrum of light that comes from a source (see idealized spectrum illustration top-right) can be measured. To determine the redshift, one searches for features in the spectrum such as absorption lines, emission lines, or other variations in light intensity. If … Zobraziť viac The redshift observed in astronomy can be measured because the emission and absorption spectra for atoms are distinctive and well known, … Zobraziť viac The opposite of a redshift is a blueshift. A blueshift is any decrease in wavelength (increase in energy), with a corresponding increase in frequency, of an electromagnetic wave Zobraziť viac The history of the subject began with the development in the 19th century of classical wave mechanics and the exploration of phenomena associated with the Zobraziť viac In general relativity one can derive several important special-case formulae for redshift in certain special spacetime geometries, as summarized in the following table. … Zobraziť viac The interactions and phenomena summarized in the subjects of radiative transfer and physical optics can result in shifts in the … Zobraziť viac WebThis was a momentous discovery and dramatically expanded the scale of he known Universe. Hubble later went on to observe the redshift of galaxies and propose that this was due to their recession velocity, with more distant galaxies moving away at a higher speed than nearby ones.

http://www.astrosurf.com/buil/redshift/demo.htm WebHubble had already used this knowledge in his 1924 discovery that the Andromeda nebula, containing a variable star, was more than 900,000 light years from Earth -- way beyond our own galaxy -- a ...
The estimated distance of the Andromeda Galaxy from our own was doubled in 1953 when it was discovered that there is another, dimmer type of Cepheid variable star. In the 1990s, measurements of both standard red giants as well as red clump stars from the Hipparcos satellite measurements were used to calibrate the Cepheid distances.

WebThis contrast in distance led Hubble to believe the Andromeda Nebula was a galaxy in its own right. Hubble used this technique to study other so called “nebulae” in the universe, and concluded that millions of galaxies existed beyond our own. ...
