Sunday: The moon lies between the planets Jupiter and Saturn tonight. Tomorrow night, it moves much closer to Saturn. At 9:30 p.m., the moon is 2 degrees to the lower right of Saturn. The two will remain near each other all night, with the moon passing less than one degree below Saturn.
Monday: The International Space Station makes a low pass through the sky tonight. The space station starts off 10 degrees above the south-southeast horizon at 9:28 p.m. gliding through the tail of Scorpius. The spacecraft reaches its highest point when it passes just a degree north of the moon and Saturn. It continues moving east and disappears into Earth’s shadow at 9:32 p.m., 10 degrees above the eastern horizon.
Tuesday: The full moon occurs at 4:38 p.m. The July full moon is known as the Full Buck Moon. At this time of year, the antlers of many deer are beginning to push through their foreheads with a velvety coating of fur. It is also known as the Thunder Moon, since thunderstorms are most frequent this time of year.
Wednesday: This morning, try to catch a final glimpse of the red planet if you can. Mars is only a few degrees above the western horizon after sunset. The best way to find Mars will be to scan the horizon with a pair of binoculars. Once Mars disappears, it will not be visible again until October.
Thursday: Early this morning you can catch the International Space Station in the west-northwest at 5:31 a.m. The space station passes about 5 degrees above the star Altair before reaching a height of 40 degrees in the southwest. It then passes above Jupiter and by 5:37 a.m., it drops to 10 degrees in the south-southeast.
Friday: The International Space Station makes a high pass through the northern sky tonight. The ISS starts off in the west-southwest at 9:22 p.m. Three minutes later, the spacecraft is 56 degrees above the northwest horizon, passing through the handle of the Big Dipper. Moving northeast, it drops to a height of 10 degrees at 9:28 p.m.
Saturday: Close to overhead at 10 p.m. you can find the constellation Hercules. Hercules resembles the constellation Orion but only has two stars along the belt rather than three and is not as bright as Orion. In Hercules, there is an interesting double star known as Rasalgethi, located above his head. The star appears reddish orange, but through a telescope with magnification of at least one hundred times, a second companion star is visible. Depending on your eyesight, the secondary star may vary in color from yellow to white.
