We have all enjoyed the long months of summer, especially the awe-inspiring views of the Milky Way Galaxy. This mystical glow of millions of distant suns now stands directly overhead as the sky darkens and sets before the break of dawn. This is also your last chance to catch Scorpius, the planet Jupiter and Sagittarius in that order, located in south-west skies.

On the morning of October 9th, the Lunar CRater Observation and Sensing Satellite (LCROSS) will crash land into the moon. Is this spacecraft out of control you might ask? On the contrary. This deliberate impact is a planned end to a mission that had a bit of a hiccup last month.

This month’s constellation plays a role in the famous mythological story called the “Royal Family of Constellations”. As the fable went, King Cepheus and Queen Cassiopeia sacrificed their daughter Andromeda to the Sea Monster, Cetus. Our hero Perseus happened by with his slain prize - the Medusa’s head, stowed in a potato sack.

The biggest story of the month is the unexpected outburst of 17P/Comet Holmes. This outburst occurred over a short 24 hour period starting October 23rd. By the 24th, the comet had increased its brightness from magnitude 17.5 to magnitude 2.5, which is an order of one million times. At the time of writing this article, the comet halo is still growing but the inner portion is fading a bit. It is still a very impressive object.

Throughout time, the winged horse Pegasus has appeared in many different mythological stories and legends. One of the most famous tales is the “Royal Family of Constellations” where Perseus the hero rescues Andromeda the maiden from the sea monster Cetus. Upon slaying the monster, Perseus and Andromeda ride the winged horse into the sunset.  

If you took part in the Messier Marathon this past March, you no doubt had to negotiate the swarm of galaxies in Virgo, Leo and Coma Berenices. Many of these objects do not reside near reference stars, thus making the hunt even more challenging.

About an hour after sunset local – lookup, way up. What greets you is the most recognized constellation in the sky, Ursa Major – aka the Big Dipper or Big Bear. Taking up 1,280 square degrees of sky, it ranks third behind first-place Hydra and second place Libra. With the great beast prancing overhead, you will have a great opportunity to examine its many galaxies through the least amount of atmospheric turbulence and distortion.

Over the course of the past few months, I have pointed out one or two globular clusters associated with a particular constellation. However, as the months' tick by, we come to that time of year where these starry blobs containing tens of thousands to hundreds of thousands of stars are seen in greater numbers. One reason why summertime is best for viewing globular clusters is they tend to populate in most part, around the heart of our galaxy, near the nucleus.
