The Atacama Cosmology Telescope @ACT_Pol measures the Hubble constant using the cosmic microwave background to be 68 km/sec/Mpc. That's in agreement with the Planck satellite, and disagreement with direct measurements. A mystery! nature.com/articles/d4158…
Greg Mack retweeted
The James Webb Space Telescope has a new target launch date: Oct. 31, 2021🎃🦇 — This is about a half-year delay from its previous target, caused by COVID-19-related disruptions. @NASA states the nearly $10 billion mission will require no additional funds. nasa.gov/press-release/…
