Can anyone explain to me the red shift
It doesn't happen very often and its not all that predictable - so if there is a good one you might be able to see it after reading about it in the newspaper. They're generally visible for a week or so if they get bright enough.Originally posted by Viper
My other question is that I've heard a lot about stars going super nova, do you know when I can view these?
Redshift is the phenomenon where light from a distant object appears to be shifted towards the red end of the electromagnetic spectrum. It is caused by the expansion of the universe and is a key piece of evidence for the Big Bang theory.
Redshift is measured using spectroscopy, which involves breaking down light into its different wavelengths. The amount of redshift is determined by comparing the observed wavelengths to the expected wavelengths of known elements.
Redshift and blueshift are opposite phenomena. While redshift involves light appearing to shift towards the red end of the spectrum, blueshift involves light appearing to shift towards the blue end. Blueshift is caused by objects moving closer to us, while redshift is caused by objects moving away from us.
Redshift is a consequence of the expansion of the universe. As the universe expands, the space between objects also expands, causing the light from those objects to be stretched and appear redshifted. The amount of redshift is directly related to the distance between the object and the observer, providing evidence for the expansion of the universe.
Studying redshift can provide valuable information about the age, size, and expansion rate of the universe. It can also give insights into the formation and evolution of galaxies and the distribution of matter in the universe. Additionally, redshift measurements can be used to determine the distances to faraway objects, aiding in our understanding of the vastness and complexity of the universe.
