Sky Phenomenon Along 2010

I always love when an article told about sun, star, moon, planets, asteroid...our universe. For sky lover, along 2010, you can see many sky phenomenon almost each month. Use your telescope (i wish i can have this one hehe..) to see some of them (while we can see with naked eyes for the others). Here's the list...and don't forget.

Why is The Sky Blue?

Why is the sky blue? Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors. The colors in white light are red, orange, yellow, green, blue and violet. You can see these colors when you look at a rainbow in the sky.

The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust.

As sunlight goes through the air, it bumps into the molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky.

Meteor Shower, Second from Third Wonders of January 2010

The Quadrantid Meteor Shower

January's best meteor shower is the Quadrantids, which peaks overnight from January 3 to 4. The meteors will be somewhat diminished by a moon just a few days past full phase. The Quadrantids can have a zenithal hourly rate of 90, which is a rather strong show. Meteor showers tend to be named after the region of sky from which they appear to emanate, but the constellation Quadrans Muralis is no longer on any star maps. This extinct constellation was in the region of Hercules, Bootes, and Draco. Look north as soon as it gets dark to catch some "shooting stars".
