Are Martians invading the Earth? If so, where are they? They are actually all over the planet, but they blend in so easily because they are Martian meteorites. These meteorites are pieces of Mars that end up in orbit in our solar system and then collide with Earth. A group of them fell to Earth in Morocco in July, but astoundingly they were witnessed passing through the atmosphere and then were actually found on the ground. Through these rocks we can analyze Mars without actually going there. Also, we are coming to the peak of the 11 year sun spot cycle in 2013. The major effects of this cycle include the sighting of Northern and Southern lights and also tremendous effects on communication systems. And don’t miss what’s in the night sky this week. All this and more on this week’s Sky Talk.[audio: st20120130.mp3]
