PLANET DISCOVERED ON THIS DAY IN 1846

German astronomer Johann Gottfried Galle discovered the
planet Neptune at the Berlin Observatory.

Neptune, generally the eighth planet from the sun, was
postulated by the French astronomer Urbain-Jean-Joseph
Le Verrier, who calculated the approximate location of the
planet by studying gravity-induced disturbances in the
motions of Uranus. On September 23, 1846, Le Verrier
informed Galle of his findings, and the same night Galle
and his assistant Heinrich Louis d’Arrest identified
Neptune at their observatory in Berlin. Noting its movement
relative to background stars over 24 hours confirmed that it
was a planet.

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 Hubble Space Telescope was launched into
low Earth orbit in
1990 and remains in operation. It was not the
first space telescope,
but it is one of the largest and most versatile, renowned both as a
vital research tool and as a public relations boon for
astronomy.

The Hubble telescope is named after astronomer Edwin Hubble
(below) and is one of NASA’s
Great Observatories.

HEARD FOR THE FIRST TIME ON THIS DAY IN 1859

Big Ben Rings Out For the First Time - HISTORY    
   


The famous tower clock known as Big Ben, located at the top of the 320-foot-
high Elizabeth Tower, rang out over the Houses of Parliament in Westminster, London, for the first time on May 31, 1859.

After a fire destroyed much of the Palace of Westminster—the headquarters
of the British Parliament—in October 1834, a standout feature of the design
for the new palace was a large clock atop a tower. The royal astronomer, Sir
George Airy, wanted the clock to have pinpoint accuracy, including twice-a-
day checks with the Royal Greenwich Observatory. While many clockmakers dismissed this goal as impossible, Airy counted on the help of Edmund
Beckett Denison, a formidable barrister known for his expertise in horology,
or the science of measuring time.

Susan B. Anthony was an American social reformer and women’s rights
activist who played a pivotal role in the
women’s suffrage movement.

The Susan B. Anthony dollar is a United States dollar coin minted from 1979
to 1981, when production was suspended due to poor public acceptance,
and then again in 1999. Intended as a replacement for the cumbersome
Eisenhower dollar, the new smaller one dollar coin went through testing
of several shapes and compositions, but all were opposed by the vending
machine industry, a powerful lobby affecting coin legislation. Finally, a
round
planchet with an eleven-sided inner border was chosen for the
smaller dollar.
