Over the last few months you must have read dozens of articles, online or in print, about the Omicron variant of COVID-19. Fortunately, this is not one of them. This article is about Omicron² Eridani. It is a faint star in the constellation of Eridanus, the River.… Continue reading.
DESI – The Dark Energy Spectroscopic Instrument (DESI) is only about 10 percent of the way through its five-year operation, but its team, led by astronomers at Lawrence Berkeley National Laboratory, has already produced the largest ever three-dimensional map of the Universe.… Continue reading.
Hydrogen Filament – A group of astronomers at the Max Planck Institute for Astronomy has identified the radio signature of a giant filament of atomic hydrogen 3,900 light-years long and 130 light-years wide, located near the far side of our Milky Way galaxy.… Continue reading.
What crowd is this? What have we here? We must not pass it by;

Three quarters of a century ago, during the Second World War, the famous Harvard astronomer Harlow Shapley, along with Charles Federer, founding editor of Sky and Telescope Magazine, launched an association of astronomy clubs across the United States.… Continue reading.
Hubble Resumes Observing – In late October, a computer onboard the Hubble Space Telescope detected that communications between computers and instruments were missing critical synchronization messages. All instruments were placed in safe mode so ground controllers could troubleshoot the problem. They tested each instrument independently and found all operating correctly, meaning the fault was likely somewhere in the communications, though they’re still investigating the root cause.… Continue reading.
Agreed, this seems like an awfully daffy title for an astronomy article. But there is method to the madness, and there is a story. During the late summer of 2019 there was a star party in southeast Arizona that featured a dark sky and five perfect back-to-back nights.… Continue reading.
