Weekend Sky Report / Moon and Saturn
September 06, 2019
If you’ve heard this show and have had difficulty locating some of the targets, you’re not alone. Finding them takes practice. But anyone can find the moon. And before you go back to work on Monday, you might find some inspiration… by viewing Saturn through a telescope.
You see, on Sunday night, Saturn will be right next to the moon. That way you won’t have to triangulate or wait for a certain time of night… you can just look for the moon, then look to the right. That bright yellow point of light that doesn’t twinkle is Saturn. And you can observe Saturn from almost anywhere--even in the city. Almost any telescope will show the planet’s famous rings. Obviously the better the telescope, the better the view, but… even some toy telescopes might at least show you that this is no ordinary star. Through a small telescope, the rings may appear as two bright bulges on either side of a yellow disk. Through a slightly better telescope, the image is unmistakable, and you may even see its largest moon, Titan. Through a good telescope, you can see other, fainter moons, and what’s called the Cassini division--a space between the two most visible rings, named for Giovanni Cassini, the 17th Century Italian astronomer who first discovered it. Also of course the namesake for the famous NASA spacecraft that studied the planet.
Many people aren’t even aware that the rings of Saturn are visible from Earth--much less from our own backyards with simple consumer telescopes. And one good look at Saturn’s rings is enough to hook almost anyone on astronomy.
So on Sunday night… find the moon… then look to the right to find the jewel of the Solar System.

The Orion Nebula is just over 1300 light years from our solar system, and it's believed to be an enormous 24 light years across. Because it's so big, and... relatively close, it's easily visible with binoculars or a telescope, even under fairly bright, suburban skies.

looking at a full moon through a telescope, you notice a lot. The craters, the so-called "seas," the "Ocean of Storms-" that's the big sea... So just what are all those geographic features?

Around 9pm, look low to the southeast to find the brightest star in the night sky. Bright white, twinkling Sirius. Above it, you'll see that iconic winter constellation Orion the Hunter. The orange star at his shoulder is the red supergiant Betelgeuse. Draw a line between Sirius and Betelgeuse, then look to the left, or east to find Procyon (PRO-see-on), another bright white star, and there you have it. A large, nearly perfect equilateral triangle of bright evening stars.

Betelgeuse is one of the largest stars we've ever discovered. If you were to replace the sun with Betelgeuse, it would engulf all four inner planets from Mercury to Mars, and, by some estimates, even Jupiter.

At 2300 light years away, the cluster resembles an upside-down Christmas tree with the brightest star representing the base of the tree. The other stars form a loose cone shape that makes it look like Christmas tree lights.

Auriga is home to three Messier objects, named after 18th century French astronomer Charles Messier, famous for his catalog of deep-sky objects. The three objects are all open clusters, which can be seen through most backyard telescopes.

The three stars that make up Orion's belt is the giveaway. But there's a lot more to appreciate.

A globular cluster is a densely-packed group of stars bound by their own collective gravity. The globular we're looking for tonight is Messier 15 -- also known as the Globular Cluster in Pegasus.

Lots of people can see just those three stars of Orion's belt and know what they're looking at. But look a little closer at the belt with a telescope, or even a good pair of binoculars, and you'll see many more stars.

There was a full moon this past Tuesday, which means this weekend the moon is in the waning gibbous phase. Waning moons are out in the morning, and this week's mostly clear skies have given us a good view--particularly those of us who drive west into work. If we get clear skies this weekend, take a moment to look west at the gibbous moon.

The Pleiades is a collection of B-type stars, which are bright, hot, and blue in color. And the stars of the Pleiades are close too-around 450 light years away, which contributes to its brightness. And while you don't need a telescope or even binoculars to appreciate the Pleiades, it certainly helps.

Cassiopeia is popular with amateur astronomers because it's large, bright, and the main reference point for several deep-sky objects.

This weekend (Sat, Oct 26, 2019), you can find Uranus in the Eastern sky between the constellations Aries and Pisces with Aries to the left, and Pisces to the right.

The Great Globular Cluster in Hercules, or M13 was discovered by astronomer Edmund Halley in 1714, and found its way into Charles Messier's catalog of comet-like objects fifty years later.

It's a full moon this weekend...so what are we seeing when we look at the moon?

International Observe the Moon Night was started in 2010 by NASA. Specifically, the group responsible for its Lunar Reconnaissance Orbiter. Launched in the summer of 2009, it continues to deliver important data today, as well as photos and video of the lunar surface--including the landing sites of all six successful crewed lunar surface missions.

The aptly named Double Cluster is a favorite among budding amateur astronomers. Not only because its brightness makes it easy to find, but also because its beauty keeps observers coming back.

The brightest star in the constellation Perseus is Mirfak, and it's where you need to look to find this weekend's target.
