Astronomer Designed Giant Radio Telescope in Puerto Rico

Thought I'd post this for all the space buffs out there.

His observatory spotted the first planets beyond our solar system, lakes on Saturn's moons, and pulsars.

Film buffs will know the 1,000 ft. wide Arecibo Observatory from Contact and GoldenEye.

And after all, we're all about focusing Electromagnetic Radiation, right?

ALBANY, N.Y. -- Astronomer and engineer Bill Gordon, who designed the photogenic radio telescope in Puerto Rico that spotted the first planets beyond our solar system and lakes on one of Saturn's moons, has died in New York state. He had recently undergone hip surgery and was 92.
Gordon died Tuesday of natural causes, according to officials at Cornell University in Ithaca, the Ivy League college where he served on the engineering faculty from 1953 to 1966.


He designed the Arecibo Observatory's radio telescope in the 1950s, a 1,000-foot-wide dish in a sinkhole surrounded by forested hills.

The telescope uses radio waves to observe the cosmos, just as optical telescopes use visible light.

=> It can beam millions of watts of electromagnetic energy into space and it can gather and focus echoes as faint as a millionth of a single watt. <=



DISCOVERIES
Within a year of its opening, it was used to determine the planet Mercury's period of rotation. After radio pulsars -- rotating neutron stars -- were discovered in 1967, the observatory played a prominent role in studying their properties. Along the way, it was used to map the surface of Venus.
The astronomers Joseph Taylor and Russell Hulse discovered the first binary pulsar at Arecibo in 1974, leading to a 1993 Nobel Prize in physics.
In 1990, Polish astronomer Aleksander Wolszczan used the telescope in the discovery of a pulsar in the constellation Virgo that was shown to be orbited by the first planets to be detected beyond Earth's solar system.


PROMINENT ROLES
The telescope, owned by the National Science Foundation and operated by Cornell, had a prominent role in the 1997 Jodie Foster film Contact, based on a Carl Sagan book about the search for extraterrestrial life -- a hunt that continues at the observatory. In the 1995 James Bond movie GoldenEye, the telescope's platform figured in the climactic fight scene.


``When we were talking about building [the telescope] back in the late '50s, we were told by eminent authorities it couldn't be done,'' Gordon said at Arecibo's 40th Anniversary in 2003.

``We were in the position of trying to do something that was impossible and it took a lot of guts and we were young enough that we didn't know we couldn't do it.''

These days, the telescope's work includes searching for asteroids and comets headed for Earth. It also discovered lakes of hydrocarbons on Saturn's moon Titan.

Gordon was born in Paterson, N.J., and earned a bachelor's degree from Montclair State Teacher's College, a master's degree from NYU and his doctorate at Cornell. He was a professor and administrator at Rice University in Texas from 1966 until 1985.
 
If we knew there were lakes on Saturns moons, and that it takes many years to get there. We should have sent someone up years ago to look for life.
 
Well, they're lakes of hydrocarbons, not so sure of what could live there (hydrocarbon based life?).

On the other hand, Exxon could set up some wells there!

But on the other/other hand, what are you gonna do with oil in space?

Hmmm... "Honey, let's go to the methane lake house on Titan this summer, OK?" :grin:

BTW, the signal to Saturn/Titan takes 2.25 hours roundtrip @ the speed of light...

Moons of a gas giant are one of the more likely(relatively) places to find life in the solar system, possibly extremophiles which live on geo-thermal energy generated by planet's tidal forces on the moon, rather than heat provided by the sun.

So far unlikely on Titan. No water that we know of. But that's how one theory goes.

But Huygen's landing on Titan was pretty thrilling.
 
This has always gotten me. Weren't Earth's early oceans hydrocarbon oceans, which gave rise to life?


The early oceans were hydrocarbons before they were water? I hadn't heard that.

I have heard there are new theories that today's hydrocarbons on Earth are a product of rock in the earth's mantle, not a byproduct of the remains of early life (plant, dinosaur, plankton) under extreme pressure.

That is, made by sedimentary rock, not simply stored there.
