UY Scuti – a bright red supergiant and pulsating variable star in the constellation Scutum. Using our Sun as the standard measure of 1 solar radius, UY Scuti measures 192 solar radii – or an approximate radius of 750,000,000 miles which would extend past the orbit of Jupiter.
First studied in 2015 this unusual F-type star (KIC 8462852), located in the constellation of Cygnus, exhibits bizarre behavior. Sometimes the star’s brightness dims by a couple percent, but sometimes it dips by as much as 20%, and for days to weeks at a time. Not to mention the long-term fade that appears to be plaguing the star.
The Boötes Void is an enormous, approximately spherically-shaped region of space, containing about 60 known galaxies in a volume that should contain 10,000. It is located in the vicinity of the constellation Boötes, hence its name.
