Redshifted star
Web12. dec 2012 · Astronomers using the NASA/ESA Hubble Space Telescope have uncovered seven primitive galaxies from a distant population that formed more than 13 billion years ago. In the process, their observations have put forward a candidate for the record for the most distant galaxy found to date (at redshift 11.9), and have shed new light on the … Web(2) The stellar object is the nuclear region of a galaxy with a cosmological red-shift of 0-158, corresponding to an apparent velocity of 47,400 km/sec. The distance would be around 500...

Web21. sep 2015 · Red Shift is an observable effect when you analyze the spectroscopic signature of an electromagnetic radiation source that is so far from us that the expansion of the universe (whose unit of measurement is called the Hubble Constant) is noticeable because of the frequency drop, called Doppler effect. In short, it works like this:

Webredshift: When the light an object emits is displaced toward the red end of the spectrum it is said to be redshifted. In general, photons of light that are emitted at a source at one energy and detected by an observer at a lower energy are redshifted.
