Femtosecond lasers are used to fabricate precision ultrathin mirrors for space telescopes that capture star formation and other high-energy space events.
A new way to make telescope mirrors could sharpen our view of the universe.

Turns out astronomers choose Hawaii for powerful telescopes because they want to wear shorts and get a good tan.
A new study published in Nature suggests building powerful telescopes in Hawaii and Northern Chile might not be such a great idea.
Are “invisible terrestrial entities” all around us? Physicist says yes and has photos to back it up.
Dr. Santilli says there is an “effective conspiracy to suppress, or refuse to investigate, novel theories which may conflict with established scientific theories. Such will surely be the case with Santilli’s newest discovery – a concave-lens telescope that reveals an invisible part of the universe many of us would just as soon stay hidden behind…
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…
Ha, ha. Would be even funnier if it were a rifle scope
About the European Extremely Large Telescope (E-ELT) – Scientists create the world’s largest telescope on top of a mountain.
The European Extremely Large Telescope (E-ELT) will be more powerful than any telescope on earth. Its huge mirror will measure 39.3 meters 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!
Galileo Galilei’s Free Fall from the Leaning Tower of Pisa. Yep, it really happened.
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…
The results are in: small planets like our own are extremely abundant in the universe
The results are in – our galaxy harbors at least one hundred billion planets, many of them Earth-sized meaning, small planets like our own are extremely abundant in the universe. On Monday, scientists announced that NASA’s Kepler space telescope has discovered another 461 potential new planets, most of which are the size of Earth or…
