Outer Space is the last great frontier for man to explore.  Since space seems to have no end, it is highly unlikely we will ever get to know more than a grain of sand in the lifetime of human beings.  Still, what we DO know is completely fascinating and eye-opening.  For instance, footprints on the moon will be there for 100 million years because there is no atmosphere so no wind, rain or natural means to erode it. Yale University suggests that a planet called 55 Cancri e might be made up of graphite and diamond.  Imagine it:  a planet covered in diamonds!  You can see this planet in the Cancer constellation.  NASA is continually making efforts to try and explore further into space but our tech isn’t there quite yet.  Right now, a full NASA space suit costs 12 million dollars so what would the tech to get to a planet of diamonds possibly cost.  Crazy! The Andromeda Galaxy is about to crash into the Milky Way, where our solar system is located.  The two will collide to form a giant elliptical galaxy and the force of the blow will send the Sun careening into another part of space.  But, breathe easy, it won’t be happening for another 3 and 1/2 billion years from now. Clear Your Schedule:  Halley’s Comet will return in 2061.  It is only seen once every 75 to 76 years.
