Astronomers using the Very Large Array in New Mexico spent 40 hours observing galaxy AGC 114905, which seemed to have little to no dark matter in 2019 observations. The new evidence shows there is no dark matter in the galaxy at all. Plus, more Hubble and JWST updates, an eclipse over Antarctica, and an interview with Dr. Franck Marchis about citizen science.

ALMA Data Helps Confirm Mechanism Behind Gas Stripping of Galaxies

Nov 22, 2021 | Astrobiology, Daily Space, Earth, Galaxies, Mars, Moon, Sky Watching, The Sun

A new research project called the Virgo Environment Traced in Carbon Monoxide Survey (VERTICO) used data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) to understand just what is stripping star-forming gases out of the Virgo Cluster of galaxies. Plus, calderas, a mass extinction, and this week’s What’s Up.

Based on X-ray detections from the Neil Gehrels Swift Observatory, scientists used the Chandra X-ray Observatory and found rings called light echoes moving out from a black hole and its companion star, reflecting off the surrounding dust clouds. Plus, solving the puzzle of the Sun and using glassy nodules to find a meteorite impact.
