| | The distance scale is fundamental to cosmology. How big is the universe? is pretty much the first question we ask when we look at the Big Picture. The primary yardstick we use to describe the scale of the universe is Hubble's constant: the H0 in v = H0 D that relates the recession velocity (redshift)...

Travel
| I get a lot of questions asking why the James Webb Space Telescope is infrared, and how its images can hope to compare to the (primarily) optical Hubble Space Telescope. Why would NASA build something that isn't going to capture beautiful images exactly like Hubble does? The short answer to this is that JWST will absolutely capture beautiful images of the universe, even if it won't see exactly what Hubble does. (Spoiler: it will see a lot of things even better.) There are legit scientific reasons for JWS...
