The Astronomical World of Harry Potter: Part 3 – Dumbledore and Fenrir

the astronomical world of harry potter

In the past two blog postings we uncovered how some characters in the Harry Potter universe are tied to Greek, Roman, and Norse mythology.  Not only are certain names shared, but the stories between the character and the myth from which its name is derived are actually intertwined.  In the first blog posting we dealt mainly with two of Harry’s classmates:  Draco and Luna.  In the second blog posting we looked at two members of the family Black:  Sirius and Bellatrix.  Now it is time we took a closer look at one of Harry Potter’s fiercest enemies and one of his fiercest allies:  Fenrir Greyback and Albus Dumbledore.

It’s Time to Look for Orion, the Mighty Hunter

ImageOrion, the hunter, is one of the most popular constellations in the night sky; so you may have already seen him this winter or in late fall. Throughout the year, no matter the season, when I am in schools with our Discovery Dome portable planetarium someone often asks me to point out Orion. The mighty hunter is also one of the largest and easiest constellations to find. Most people find it by locating the three stars that make up Orion’s “belt” which is an asterism or recognizable group of stars that are part of a constellation. The names of the three stars that make up Orion’s belt are Alnitak, Alnilam and Minatka. One of the brightest stars in the sky is on Orion’s right shoulder. It’s called Betelgeuse.

Orion’s belt is the only group of three stars that are spaced so evenly making them very easy to recognize. Once you have found the belt, the hunter easily pops into view especially when it is right overhead during the cold evenings of winter.

Besides being easy to spot, the constellation Orion is also where you will find one of the most beautiful objects in the night sky, the Orion Nebula. Count down to the third bright object in Orion’s sword and you will find not a star but the Orion Nebula. With binoculars focused on this object, you will find many stars rather than one.

So the next time you look for Orion in the night sky be sure to also take a look at the third object in his sword for the giant cloud of gas and dust that makes up this birthplace or stars and solar systems.

Make Your Own Spray Paint Space Painting In One Minute!

1 minute space painting by Brandon McConnell

Brandon McConnell has been making some very cool looking spray paint space paintings for quite some time now.  Like so many other artists, his artistic journey began by doodling things on paper during the school hours.  I’m sure he got in trouble with this from time to time but it did set the ground work for him to win first prize in his High School art contest for his ink and airbrush art.  Then one day, during a day trip to Mexico, he came across a street artist doing paintings with spray paint.  After buying some of the street artist’s pieces he was able to study them at his home and learn the  methods used to create them.  The next day he went out, bought some spray paint cans, and started making his own space art.
