An novel method that could add texture to other worlds.
Using new Gaia data, the authors update the stellar radii for the majority of Kepler’s stars. While they find that most stars have similar radii to previous reported values, there are some large discrepancies.
Yes, even astronomers get competitive. Which team will develop the best method to measure the Hubble constant, H0, using information derived from strong gravitational lensing images?
I wanted to call this post “Hubble Trouble,” but six hundred people have already done that.
Two attempts to measure the masses of retired A-type stars give two different results.
In 1972 astronomers witnessed the first full galaxy collision, not by looking up at the sky but by peering at a small screen in a very large box. The methods and implications are enshrined in modern astrophysics, but it is the results themselves that still truly amaze, stunning simple images of galaxies, playfully strewn and joyfully picked apart. A full exploration of a galaxy of a scale not matched before or since.
