Did you know China has a telescope on the Moon?

Did you know China has a telescope on the Moon? The 15-centimeter telescope was delivered to the moon aboard the Chang’e 3 lunar lander which landed on the moon in December 2013.  In the photo above, the small arrow points to the Chang'e 3 rover and the big arrow points to the Chang'e 3 lander and telescope base. If you’ve looked through a telescope before, you know that because of the earth’s rotation, the stars do not stay fixed in the viewfinder for very long. Since the moon rotates 27 times more slowly than Earth, the scope is much easier to stay fixed on stars.  The scope sees in ultraviolet light too, a big advantage for any telescope outside of the earth’s atmosphere. The telescope is remote…

European Extremely Large Telescope (E-ELT) – Scientists create the world’s largest telescope on top of a mountain

Once they finish building it, the European Extremely Large Telescope (E-ELT) will be more powerful than any telescope on earth. Its huge mirror, which is used to gather the faint light of faraway galaxies, stars, and planets (allows astronomers to see further than ever), will measure 129 feet ( meters or 1,547 inches) and require microscopic precision to align the 800 hexagon-shaped pieces of mirror it will take to construct the telescope. E-ELT will be more than three times larger than any telescope on the planet!  To get an idea of how big E-ELT will be, take a look at the picture above and find the pickup truck to compare its size to the size of the E-ELT telescope.  Wow! E-ELT will be built on…

Galileo Galilei’s Free Fall from the Leaning Tower of Pisa

Galileo, pronounced gal uh LAY oh (1564-1642), an Italian astronomer and physicist, has been called the founder of modern experimental science. Galileo made the first effective use of the refracting telescope to discover important new facts about astronomy. He also discovered the law of falling bodies as well as the law of the pendulum. Galileo designed a variety of scientific instruments. He also developed and improved the refracting telescope, though he did not invent it. Galileo Galilei was born in Pisa (yep, the site of the famous leaning tower) on Feb. 15, 1564. In the early 1570's, his family moved to Florence, and Galileo began his formal education at a school in a nearby monastery. Galileo's father, determined that his son should be a doctor,…
