Voyager 1 and 2

Humans have always gone to the frontiers and explored making the last true frontier outer space.  Humans have always been fascinated by space and have always to the stars for directions or a familiar pattern. Recently humans have been sending things to outer space and now the Voyager 1 and 2 have crossed the heliosphere.  The heliosphere is the immense magnetic bubble containing our solar system and it extends beyond Pluto and Voyagers 1 and 2 are now there first and only ships humans have created to leave the heliosphere and enter interstellar space.  Voyager 1 was launched September 5, 1977 but is traveling 38,000 mph and while Voyager 2 was launched August 20, 1977 and has been traveling 35,000 mph. This means that even though Voyager 2 was launched first Voyager 1 was able to pass Voyager 2 because Voyager 1 is traveling faster.  Both are still operational and continue to provide data about interstellar space.

The Pyramid looks like hill from the distance


The tallest pyramid in the world is the pyramid of Giza in Egypt. However the largest pyramid in terms of volume is the pyramid of Cholula in Puebla, Mexico. Cholula is the oldest continuously inhabited city in Mexico being inhabited since 2 Century BC.  It is 180 feet tall but is 1300 by 1300 feet wide making it the largest pyramid (in volume) in the world. After the city was conquered the Spanish built lots of churches in the city and one of the churches was built above the pyramid. Now from far  it looks like a hill with a church on top of it and there are parts that have been restored for the public.
