Leaping Into Leap Year!
It’s almost here, Leap Day! When? On Wednesday, February 29. That will give us 366 days in 2012 instead of 365. Why do we need that extra day, anyway? Believe it or not, without a leap year about every four years, we would lose days.

Solar Storm is Impacting Earth Right Now
Right now a strong storm is taking place on the sun that is releasing solar flares and photons that are bombarding the Earth. On Sunday night, the sun released a coronal mass ejection which is magnetic energy stored in the suns atmosphere. This eruption caused electromagnetic radiation, radiation in the form of protons and finally plasma to be released into space, some of which is hitting Earth. The plasma may cause some problems on Earth by interrupting satellite communications and affecting some aircraft traveling near the poles.

Plankton -- Why Is It So Important?
Plankton are tiny living creatures that we never think about, yet they are extremely important to our Earth as a source of almost 50% of our oxygen and a major source of food for sealife. Plankton are tiny plants and animals in oceans and lakes. Sometimes they are so small, you cannot see them with your naked eye. When they mass together, they can make oceans look green or cause dark spots in the water when seen from above. There are two main categories of plankton: phytoplankton and zooplankton.
