The blue gas giant, which has a diameter four
times that of Earth, was named for the Roman
god of the sea. It has eight known moons, of
which Triton is the largest, and a ring system
containing three bright and two dim rings.

It completes an orbit of the sun once every
165 years. In 1989, the U.S. planetary
spacecraft Voyager 2 was the first human
spacecraft to visit Neptune.

The autumnal equinox is an astronomical event marking
the start of fall in the Northern Hemisphere. An equinox
happens when the center of the sun crosses the "celestial equator," an imaginary extension of the Earth’s equator
into space.

On September 23, 1875, Billy the Kid was arrested for the first
time after being involved in the stealing of a basket of clothes
from a Chinese laundry. It was a result of a 15-year-old’s prank,
gone wrong.

He later broke out of jail and roamed the American West,
eventually earning a reputation as an outlaw and murderer
with a rap sheet that allegedly included 21 murders.

The exact details of Billy the Kid’s birth are unknown, other
than his name, William Henry McCarty. He was probably born
sometime between 1859 and 1861, in Indiana or New York.

 

An old photo purchased from a California antique shop shows the
infamous outlaw Billy the Kid, apparently taking part in a game of
croquet. The image could be worth up to $5 million. It took more
than a year of careful inspection to confirm the authenticity of
the photo.
