It will be the world's largest and most sensitive radio telescope and three times more sensitive than the Arecibo Observatory.

It is named after Wilfredo Portalatin, a technician and telescope operator at the Arecibo Observatory.

Since the Arecibo observatory is owned by the Government of the United States, direct donations by private or corporate donors cannot be made.

Motorola's Iridium engineers have consulted with radio astronomers and reached tentative understandings with the Arecibo observatory and a few others.

The scientists plan to use the combined observations from the Goldstone and Arecibo observatories to study 1994 CC's orbital and physical properties further.

Sixto González (born 1965) is the first Puerto Rican to be named Director of the Arecibo Observatory, the world's largest single dish radio telescope.

Nothing terribly original in my recommendations, but I'd recommend visits to Ponce, El Yunque, Luquillo Beach, Arecibo Observatory and,.

Another M-type, 216 Kleopatra, was imaged by radar by the Arecibo Observatory in Puerto Rico and has a dog bone-like shape.

Zaitsev's proposal for a musical message - the "First Theremin Concert for Extraterrestrials" - was submitted to the Arecibo Observatory in July 2000.

Arecibo Observatory The Arecibo Observatory is the largest single-unit radio telescope ever constructed and one of the world's most powerful radar-radio telescopes.

When taveling from the northern coast of Puerto Rico, PR-129 can be used to reach the Arecibo Observatory and the Camuy River Caverns Park.

But now, the great dish antenna of the Arecibo observatory began to gather in a riot of faint signals, giving the star its most discriminating look yet for hints of invisible planets and intelligent life.

They established the Arecibo Science Advocacy Partnership (ASAP), which was meant to advance the scientific excellence of Arecibo Observatory research and to publicize its accomplishments in astronomy, aeronomy and planetary radar.

A few weeks after the Sagan quiz, Dr. Drake had the message beamed from the Arecibo observatory in Puerto Rico toward M13, a dense cluster of hundreds of thousands of old stars orbiting the fringes of the Milky Way.

In the meantime, officials plan to try to have a giant radar antenna at the Arecibo observatory in Puerto Rico and the Goldstone radar station in California bounce signals off the two objects to confirm whether they are parts of Contour.

And this situation, which applies to observations that Frank Drake of Cornell and I have recently performed at the Arecibo Observatory, can only become more complex-that is, more dependent on computers-with the listening devices likely to be employed in the near future.

But much of the technology originally built into the great Arecibo Observatory with its 1,000-foot dish antenna was showing signs of age, and the telescope had always suffered from the same kind of myopia that marred the Hubble Space Telescope until it was fitted with corrective lenses.

For example, if the ,000-foot radio telescope at the Arecibo observatory in Puerto Rico were to transmit information at the rate of one it (binary digit) per second with a bandwidth of one hertz, the signal could be received by an identical radio telescope anywhere in the galaxy.

In 1974, the Arecibo Observatory transmitted a message toward the M13 globular cluster about 25,000 light-years away, for example, and the use of larger antennas or shorter wavelengths would allow transmissions of the same energy to be focused on even more remote targets, such as those attempted by Active SETI.
