TNRTB Classic: More Standard Candles
Earlier this week I discussed the newly discovered advantages of using active galactic nuclei as standard candles for improving precision cosmology. In the past, other standard candles have helped astronomers explore remote regions of the cosmos from the safety of planet Earth. Check out these previous TNRTB posts for details on the brightness of the “tip of the red giant branch” and Type Ia supernovae and their usefulness as standard candles.
