Hi, this is an edited version of my Science live stream on twitch. I talk about cosmological distances, the Hubble law and calculate the distance to a galaxy by using the cosmic redshift and JWST data.

🌌 stream: https://www.twitch.tv/galactictactic

0:00 intro
0:25 proper distance
02:57 comoving distance
06:05 lumenosity distance
08:15 angular diameter distance
11:50 scale factor
18:57 Hubble–Lemaître law
22:30 redshift
23:25 spectrum
35:25 estimating the distance with JWST data
