Seven Myths About Pluto

 

Since Pluto’s discovery by Clyde Tombough in 1930, it has remained a great mystery.  It’s difficult to study since it’s about 3 billion miles away from the sun.  The Hubble Space Telescope has been able to capture images of the dwarf planet, but Hubble is really geared towards taking pictures of giant objects like galaxies, not dwarf planets–so the images we have of Pluto are fuzzy.  However, Pluto is about to get its first sharp images courtesy of the New Horizons spacecraft as it passes the dwarf planet by 7,800 miles by July 14th.  With this date looming only next month, let’s take some time to take a fresh look at Pluto and the seven biggest misconceptions that people have of it.

Why Neil Armstrong Got to Be the First Man on the Moon

Forty-six years ago, Neil Armstrong became the first man to ever walk on the moon.  Since that date, July 20, 1969, the moon has become the subject of much debate and scientific analysis.  From what Neil Armstrong first said as he took those initial steps to conspiracy theories about hoaxes, few historical events have captured the interest in mankind quite like the Apollo 11 moon landing.  However, a few facts about this event have remained obscure through time.
