Moons of the Giant Planets - Quiz
The moons of the giant outer planets have turned out to be stranger and more interesting than anyone had imagined. What do you know about the moons of Jupiter, Saturn, Uranus and Neptune?

*Apollo 11*
On July 20, 1969, Apollo 11 astronauts became the first humans to set foot on another world. Neil Armstrong, followed by Buzz Aldrin, stepped out of their lander and walked on the Moon, taking photographs and setting up experiments.

*Jupiter's family*
A team of astronomers announced their discovery of a dozen new moons for Jupiter. As you might expect, they're quite small, which is how they've evaded detection until know. That brings the known number up to 79.

*Lunar eclipse*
Here's the map for lunar eclipse on July 27 - it's the longest eclipse of the 21st century. You can find out whether you'll be able to see it from your location. But if you live in North America, it's not visible anywhere from there.

*Birth anniversaries*
(1) July 17, 1894: Belgian astronomer and physicist Georges Lemaître - made the first definitive formulation of the idea of an expanding universe, and what was to become known as the Big Bang theory of the origin of the universe.
(2) July 18, 1921 - NASA astronaut John Glenn - the first American to orbit the Earth. He had a distinguished military career before becoming an astronaut, and was a US senator afterwards. In 1998 he took part in a space shuttle mission, making him oldest person ever to go into space.
(3) July 19, 1846 – Edward Pickering - the director of Harvard College Observatory who hired the women assistants (computers), and who modernized the observatory's work in astronomy by the use of photography.
