The Great Meteor Procession of 1913
This picture depicts the event that happened on Febuary 9th 1913. A procession of Meteors seen easily in the Toronto Canada area streaked along the sky, only visible to about 1,000 people (who have reported the sighting). It is believed that this was caused by a large meteor which grazed the Earth's atmosphere and broke up. The pieces then next encountered Earth, and burned up in the atmosphere on their way down to their believed landing sight in the Atlantic Ocean.

Shadow at Point Lake
This picture depicts the Mars rover Curiosity's shadow, taken by its camera facing the opposite direction of the sun. The rover landed in the Gale Crater in August, and has been tirelessly searching for signs of ancient water ever since. It has discovered dried stream-beds so far, and will continue to search for years to come within the crater.

Asteroids in the Distance
This picture depicts asteroids outside of out planet in the asteroid belt. The summary states that asteroids striking the earth are a common occurrence So common, it happens daily! The asteroids that enter the atmosphere daily however are so small, that they burn up almost instantly when they enter the atmosphere. The larger the asteroid the rarer it is for it to enter our atmosphere. Should a large asteroid about 1 km in diameter strike the earth, it wouldn't be the impact that would cause global problems, but the dust clouds that would rise and affect the climate of the entire planet.

Infrared Orion from WISE
This picture depicts a close-up view of the Orion Nebula seen through an infrared lens from the WISE observatory. The Orion Nebula is actually visible to the naked eye, but is incredibly small and unnoticeable unless you know exactly where and what to look for. It's located in the bottom star of Orion's belt, and appears to be a reddish yellow. The lighting effect seen in the picture is caused by dust filaments floating in space in front of the stars in the Trapezium system which give off the light. Apparently, this nebula will disperse in 10,000 years or so.
