Constellation of the Month: Cassiopeia (the Queen)

Last month I was standing out in our backyard with Melissa one clear evening, pointing out the visible planets and some stars with their constellations.  She looked around and pointed to a close group of moderately bright stars in the northern sky, roughly shaped like an "M".  I answered that it was Cassiopeia, representing the queen and mother of Andromeda in the Greek mythical tale of Perseus...several constellations from this story dominate the autumn evening sky.  I picked Cassiopeia as my constellation of the month for November for that reason: its easy visibility, at least from northern hemisphere skies.  It's not that large as constellations go, but it represents the northern seasonal counterpart to Ursa Major's asterism the Big Dipper, which dominates in the springtime.  As a kid, I always learned to draw it as a sort of upside-down chair or throne including one of the fainter stars...my above pictured drawing reflects this.  Star maps usually "connect the dots" with it looking like a "W"...or "M" when it reaches its peak above Polaris, the North Star.  As you can see, the five M or W stars of the constellation are designated by the first five letters of the Greek alphabet, something that Atlantic tropical storm followers are probably well acquainted with after this record-setting hurricane season of 2020.  The additional star I connected is Kappa, and just a few degrees from it is located the remnants of one of the greatest observed supernova explosions in recorded history.  Officially known as SN 1572 for its year of occurrence, or Tycho Brahe's supernova after the famous astronomer of that time, it was around 8-9,000 light years distant but its peak brilliance reached a magnitude of -4, making it as bright as Venus back then, 448 years ago...the remnant is now only detectable through strong optical, x-ray and radio telescopes.  There are a couple of other constellations I could have picked out for November...let's see how long I can string out this monthly blog feature: I'd like to eventually cover all 88 of them...
