Video by winterover Geoff Chen of SPT observing this week! The #southernlight #Aurora are pretty amazing, especially the flare up at the end! Also fun to watch the #MilkyWay move across the sky during the movie! #southpole #Antarctica

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!

[FYI: Science Policy News @FYIscipolicy]

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.
