Two astronomical events will be out for observation in the sky for anyone who loves watching sky, planets and stars. On Tuesday night, the largest planet in the solar system, Jupiter will be lucidly visible and then the following morning it will be lunar eclipse which will be a treat for astronomers and sky-watchers.

Glimpse of both celestial events is an unusual astronomical phenomenon. Jupiter will be seen shining in the night sky, while the lunar eclipse will appear as moon will pass through Earth's shadow. There are different types of shadows that shape kind of eclipse about to form.

The penumbra is the pale outskirts of the shadow. The change in light on the moon's surface will not be that dramatic. The eclipse will be barely visible and will form fully at 7:48 a.m.

Jupiter on other hand will shine brighter than the moon itself. Jupiter is always there in the sky during this time of the year, but is clearly visible during full moon.

“About that time, even a casual observer - if he or she is looking hard enough - should be able to note a slight diminution of light corresponding to a 'smudged' or 'soiled' appearance of the moon's lower limb”, Joe Rao reports for Space.com.

The astronomical phenomena will appear in May 9, in which Mercury will pass directly between earth and the sun for the first time since 2006. The event is called “transit of Mercury,” and it will resemble a small black dot moving across the face of the sun. This will be visible in Arizona just before sunrise until noon.
