Follow the Moon in August Skies

Hey Space Placers!

This month the Moon will be your guide to finding planets, star clusters and only the brightest Perseid Meteors! With August being the last full month of summer many people get outside and go on vacation. Take some time to look up at the sky and enjoy the view as provided by your guide – the ever changing Moon.

Skywatching Highlights

One of the best meteor showers of the year, the Perseids, occurs on the night of the 12th and 13th. Unfortunately, the bright light of the Full Moon will hide all but the very brightest “falling stars”. Just watch the sky for bright meteors during the evening.

Mercury will be in the eastern sky about 45 minutes before dawn at the end of the month. If you have a clear and unobstructed horizon you should be able to see golden-yellow Mercury. On the 27th Mercury will be below and to the left of the thin crescent Moon. Binoculars will help you find the elusive planet. Also get the latest on the MESSENGER mission at Mercury:

Venus is not visible this month.

Mars is well up in the eastern sky before the light of dawn begins. The Red Planet is to the immediate left of the crescent Moon on the 25th. Just to the the left of Mars lies two bright stars, Castor and Pollux – Castor is the higher of the two. The next NASA mission to Mars, Mars Science Laboratory, named Curiosity, is at Cape Kennedy undergoing final checkout for a launch later in the year. Read More About It:

NASA’s DAWN mission arrived at Vesta on the 16th. The spacecraft is in orbit and studying the second largest asteroid in the main belt up close and personal for the next year. Then DAWN will set sail for the largest asteroid, Ceres. Read More About It: Vesta is directly opposite the Sun on the 5th and is visible all night but is relatively dim. I will post a finder chart on my blog for those of you interested in trying to spot Vesta.

Jupiter dominates the eastern sky rising at about midnight as August begins and at around 10 p.m. as the month ends. The gibbous Moon will be just above Jupiter on the 19th. Juno, NASA’s next mission to Jupiter is scheduled for launch on August 5th. You can read more about it here:

Saturn is in the West-Southwestern sky at sunset. The ringed planet is to the left a famous double star, Porrima (Gamma Virginis) all month long. The crescent Moon glides below this duo on the 3rd. NASA’s Cassini mission is till going strong and you can read about it here:

First Quarter Moon is on the 6th and this month’s Full Moon occurs on the 13th. This month’s Full Moon is called the “Full Sturgeon Moon” in recognition of the peak of Sturgeon fish in the Great Lakes and other bodies of water. Late evening the Last Quarter Moon is below the Pleiades star cluster on the 21st. New Moon is on the 28th. NASA’s Lunar Reconnaissance Orbiter remains in orbit around the Moon. Read More About It:
