The observation of redshift in the spectrum of a distant space object depends on various factors, such as the distance of the object and the sensitivity of the instruments used.
In general, redshift can be observed when light emitted by a distant object is stretched out or shifted towards longer wavelengths due to the expansion of the universe. This phenomenon is known as cosmological redshift and is a key piece of evidence for the Big Bang theory.
Scientists have been observing redshift in the spectrum of distant space objects since the early 20th century when Edwin Hubble first discovered the relationship between the redshift of galaxies and their distance from us. This allowed scientists to establish the expanding nature of the universe.
Since then, there have been numerous observations of redshift in the spectra of distant objects, including galaxies, quasars, and other celestial bodies. These observations continue to be made with increasingly sensitive instruments and advanced telescopes.
Therefore, it is safe to say that scientists have already been observing redshift in the spectrum of distant space objects for many years and will continue to do so as technology and observational techniques improve further.
