The annual Lyrid meteor shower peaks this year on the morning of Saturday, April 22nd, as Earth passes through a stream of dusty debris trailing Comet Thatcher (C/1861 G1). Comet Thatcher last visited the inner solar system in 1861, and isn’t expected to return until the year 2276. The “inner solar system” is the region between the Sun and Mars.

So, do you know how “April Fool's Day” got started? Perhaps no one really knows, but here are some of the more logical explanations.

Feel that warm spring breeze floating in the air? A return to brighter days might be triggering it! Daylight Saving Time (NOTE: No “s” on “Saving”!) begins at 2:00 a.m., Sunday March 12. Remember - “Spring ahead; Fall back” So--get up at 2:00 a.m. and turn your clock ahead an hour, then go back to sleep!
Leaves in the spring and summer are mostly a pretty uniform green color. For that, you can thank the chemical compound known as chlorophyll. Chlorophyll is responsible for the process of photosynthesis, which takes sunlight and converts it into the sugars needed to sustain the tree. There are a variety of other chemical compounds, with characteristic colors other than green, always present in the leaves; however, the green chlorophyll dominates and masks your ability to see them.
Earth is entering the debris stream of comet Swift-Tuttle and this is causing the annual Perseid Meteor Shower. This year the best time to watch the Perseid meteor shower might be the night/morning of August 11 - 12. The debris from Swift-Tuttle is in a wide belt of the sky and Perseid meteors are already visible.
