Its an outstanding week to go skywatching as the moon creeps up to the two largest worlds in our solar system.On Thursday (Sept. 16), it will be the turn of what lots of consider to be the most lovely of all telescopic things, the ringed world Saturn. The following night, the colossus of the planetary system, mighty Jupiter, will take the spotlight. Both nights, our closest neighbor in area, the moon, will be shining in its waxing gibbous stage to sign up with the spectacle. Heres what to anticipate from the planetary doubleheader.Related: The brightest worlds in Septembers night sky: How to see them (and when)First, make sure to appreciate the moon, which is best to take a look at in the waxing gibbous stage, not, as numerous believe, when its complete. A complete moon looks “flat” and one dimensional and its luster might dazzle the eye. Thursdays moon is 83% sunlit and shines about one-third as bright as when its full. In specific, have a look at the area along the terminator– that part of the moon that separates the light zone from the dark zone. Specifically in the lower part of lunar disk, you will see lots of craters casting shadows that will make them drastically stand out in sharp relief. Initially comes Saturn On Thursday night, follow the moon up toward Saturn. Your clenched fist at arms length amounts to roughly 10 degrees. So, Saturn will be situated about “half a fist” (5 degrees) above the moon. As I have actually kept in mind for many years here at Space.com, to the naked eye, Saturn does not have any exceptional functions to call attention to it. It does not have the dazzling; eye-popping brilliance of Venus or Jupiter and it does not have the fiery orange-yellow color of Mars. To the eye, Saturn appears to be nothing more than a really bright “star” that shines with yellowish-white glow. The majority of people looking around the present late-summer sky may take note of it as they look toward the southern part of the sky this week at around 10 p.m. regional daylight time. Nevertheless, any telescope with an eyepiece amplifying at least 30-power will show the well-known ring system. The very best views of Saturn depend upon the size of your telescope. My suggestion is not to use your highest power (which can amplify turbulence in the environment and make the image appear to “boil” or “quiver”), however rather a moderate magnification. With a 3-inch telescope, try 75-power. With a 6-inch, 150-power and with a 10-inch, 250-power. Even for skilled, experienced observers, the sight of Saturns rings in a large or moderate telescope still brings surprise and astonishment!As you take pleasure in the display, bear in mind that what you are seeing in Thursdays sky is an illusion of point of view. The moon and Saturn are no place near each other in space. The moon will be 232,800 miles (374,500 kilometers) from Earth, while Saturn is almost 3,686 times further away, at 858 million miles (1.380 billion km).

(Image credit: SkySafari app)If your sky is clear early on Friday evening (Sept. 17), make sure to have a look at the southeast sky about an hour after sundown. There, situated low in the east-northeast sky, youll discover an attractive sight.Youll immediately see the waxing gibbous moon, now having actually broadened to 91% lit up by the sun. On this evening, youll also see an extremely intense, silvery “star” shining with a consistent radiance to the upper left of the moon. Thats not a star, but in reality, the most significant planet in our planetary system: Jupiter. The moon and the world will keep each other company as they move throughout the sky throughout the course of the night. Jupiter is an especially outstanding planet to observe with a telescope. Its disk reveals more illuminated area than all the other planets integrated. In large telescopes, one can view its cloud belts; in some cases several appear strongly disrupted, loaded with knots and growing festoons. As always, seeing much information on Jupiter needs an excellent quality telescope, good atmospheric seeing, and persistence behind the eyepiece.If you do turn a telescope to Jupiter, make sure to look for any signs of disturbance from the area rock that knocked into it on Monday (Sept. 13). In addition, users of the extremely tiniest telescopes and even progressively held field glasses can determine some or all of Jupiters 4 brilliant moons at any given time. And Friday night they will actually be putting on fantastic show!On one side of Jupiter, all by itself, will be Ganymede, the biggest satellite in our planetary system. It is larger than Mercury, and three-quarters the size of Mars. On the other side of Jupiter, youll see Io, Callisto and Europa; at around 11:18 p.m. EDT (0318 GMT Sept. 18), these three satellites will form a striking, inverted isosceles triangle, with Io and Europa forming the base and Callisto the vertex angle. Lets go Mets! Recently, during a telecast of a New York Mets/Miami Marlins video game, a cameraman was so fascinated by Jupiter that during a lull in the ballgame he decided to focus on it, giving viewers an opportunity to see the big planet and its retinue of moons on their tv screens. Met broadcaster Keith Hernandez said, “Hey guys, Saturn is up too! Why dont you discover that?” His broadcasting partners, Ron Darling and Gary Cohen, jokingly chimed in with, “What is this now, a planetarium? Are we going to begin calling you Hayden instead of Hernandez?” (The American Museum of Natural History in New York City includes the Hayden Planetarium.)The Mets will be playing the Philadelphia Phillies on Friday night. If its clear, maybe well get another telecasted view of Jupiter (along with, possibly, the moon and Saturn) from Citifield that night, with Keith, Ron and Gary offering more “huge commentary.” Joe Rao serves as an instructor and guest speaker at New Yorks Hayden Planetarium.
