The month of May will show up the finest planetary conjunctions of the year. Naked-eye planets line-up in the eastern horizon before sunrise. On May 1, 9, 13, and 30 at 5:00 AM, Mars, Jupiter, Mercury, Venus, Uranus and Neptune will be found lining-up above the eastern horizon as shown in Figures 2, 3, 4, and 5 respectively. Uranus and Neptune will be needing a star map and a binocular or a modest-sized telescope for its proper viewing. The planets will lie among the background stars of the constellation Pisces, the Fish, except for Neptune, which will be found at the constellation of Aquarius, the Water-Bearer.
Saturn will be visible in the evening sky throughout the month. The Ringed planet will be located among the background stars of the constellation Virgo, the Virgin.

Here is another rare planetary grouping that is hard to miss! 🙂
As soon as I came across this website shared by Daniel Fischer and read about the proximity of Venus and Jupiter to each other on May 2011, I immediately ran my Stellarium software and simulated planetary positions throughout that month.
I got excited when I saw the nice planetary grouping of Jupiter, Venus, Mars and Mercury (you can add Uranus and Neptune to your count if you have binoculars or a small telescope) with the thin waning crescent Moon during the predawn hours of May 1 and 2.
All of these celestial objects will lie just within the constellation Pisces, separated by only a few degrees from each other. 😀 This is a good opportunity to spot all these planets close together during one occasion.
In order to observe this, you must have a clear eastern horizon because they will appear very low in the sky. Also, be sure to bring a pair of binoculars to help you see these objects better and wake up early to avoid the glare of the sun.
Venus is, as always, the brightest and most visible of the planets, and it can be your guide to spotting the others. About half way between Venus and the rising sun is Jupiter, the second brightest planet.
Mars will be a tiny speck just above Jupiter, and Mercury another tiny speck about half way between Jupiter and Venus. Uranus is slightly more than one binocular field above and to the right of Venus, and Neptune is much farther to the right, about 40 degrees away in Aquarius.
The planetary grouping is visible from April 23 to May 30.
Astrologers have always been fascinated by planetary alignments, and the doomsayers of 2012 have been prophesying a mystical alignment on Dec. 21, 2012. They view planetary alignments as foretellers of disasters. Modern amateur astronomers look forward to them as nothing more than grand photo ops. In fact, the modern tools of astronomers, such as planetarium softwares, show otherwise: absolutely no alignment at any time in 2012.
Happy observing 😀
