Holy Cow! Is our journey through the universe the reason for the Hubble Tension?
We move through the universe relative to the Cosmic Microwave Background. Could our movement cause our measurements of the Hubble constant to be biased?

The Tip of the Red Giant Branch (TRGB) allows for another H0 measurement to enter the ring. Credit for “H0tTake” goes to the conference “Tensions between the Early and the Late Universe” hosted at the Kavli Institute for Theoretical Physics!
A supernova that Tycho Brahe studied in 1572 may yet have something to tell us about what causes supernovae.
To unlock the secrets of the (local) universe, Adam Riess observes the brightness of supernovae and Cepheid variables to measure the distance to galaxies far, far away. Read more about his research before his plenary talk at #AAS231 on Tuesday.
As Professor Robert Fisher says, “if Yoda had to summarize Type Ia supernovae, he might have said something like ‘the classical model is a theory that misread could have been.'” What is he talking about? Come to his #AAS231 talk to find out!
A starter guide to classifying supernovae based on their light curves and spectra.
