Good Red Friday evening, Rallypoint, and welcome to this Pi Day edition of Astronomy Picture of the Day (APOD). Pi Day (March 14th) was founded in 1988 by Larry Shaw, an employee of a science museum in San Francisco, the Exploratorium. Celebrations often involve eating pie or holding pi recitation competitions.
I have done neither, but I do like this APOD Pi Day twist. What phase of the Moon is 3.14 radians from the Sun? Its 'Full' phase... like we saw last night with the lunar eclipse. Timely, no? Today's APOD is from March 2020 on Tenerife Island (Canary Islands). It wasn't quite Pi Day 2020 when this image was captured...but today marks a good excuse to revisit it again.

Over the past decade, scientists have detected a puzzling phenomenon: radio pulses coming from within our Milky Way galaxy that would pulse every two hours, like a cosmic heartbeat. The long radio blasts, which lasted between 30 and 90 seconds, appeared to come from the direction of the Ursa Major constellation, where the Big Dipper is located.
Now, astronomers have zeroed in on the surprising origin of the unusual radio pulses: a dead star, called a white dwarf, that is closely orbiting a small, cool red dwarf star. Red dwarfs are the most common type of star in the cosmos.~~~ Just A Reminder":
