Answers to Scavenger Hunt Questions
- Parkes 210
foot radio telescope in New South Wales, Australia.
- Seth Shostak
- Senator William Proxmire,
in 1981, chopped funding; NASA eventually moved back into SETI, notably with
the the High Resolution Microwave Survey (HRMS). In 1993, Nevada Senator
Richard Bryan successfully introduced an amendment that eliminated all funding
for the NASA SETI program.
- Search for Extraterrestrial
Radio Emissions from Nearby Developed Intelligent Populations.
SERENDIP IV is a supercomputer that consists of forty spectrum analyzer
boards that examine168 million channels every 1.7 seconds in a 100 MHz band
centered at 1.42 GHz. The SERENDIP instrument stores signals that peak significantly
above the background noise.
- The Allen Telescope Array
was named for Microsoft Corp. co-founder Paul Allen, who put up $11.5 million
for the project.
- Independence Day.
- Frank Drake's Project
Ozma listened for signals from space using the radio telescope at Green
Bank, West Virginia.
- Drs. Philip Morrison and
Guiseppe Coconni publish in Nature magazine the first modern SETI
article, "Searching for Interstellar Communication," which indicated, in
1959, the potential of using microwave radio for extraterrestrial communication.
- Site A is in California,
and Site B is in Colorado.
- The Arecibo message was
sent toward M13, a star cluster some 25,000 light-years away, which
means that it will take 25,000 years to get there. However, the
signal will pass near some 30 stars along the way.
- McMinnville, Oregon
- John Glenn
- Groom Lake, near Las Vegas,
Nevada
- It is a targeted SETI
search, focusing only on nearby systems.
- It is a one hectare array
of inexpensive radio telescopes.
- He writes about where
the ETs are likely to be "hanging out," and where we might expect to contact
them.
- The heroine of the movie
finds extra-terrestrial radio signals in the same ways that a typical targeted
search works.
- Feb.
22-27, 1999 at Silver Lake in California's Mojave Desert
- Allen Telescope Array
- 48,000 years (from the
ultimate destination)
- The "WOW" signal.
- Dutch
astronomer Jan Hendrik Oort
- It is a form of Supernova.
- The Large Magellanic Cloud
is 50 kilo parsecs away.
- The Mega-Channel
Extraterrestrial Assay
- Australia; The Great Barrier
Reef, July 8-12, 2002.
- Instead of listening for
radio signals, this new project searches for pulses of light from thousands
of nearby stars.
- Carl Sagan.
- 0.5 to 60 gigahertz=20
- Project Argus is an effort
to deploy and coordinate roughly 5,000 small radio telescopes around the
world, in an all-sky survey for microwave signals of possible intelligent
extra-terrestrial origin.
- In the early 1970's NASA's
Ames Research Centre commissioned a panel of outside experts to produce a
comprehensive study of the technology that would be required to carry out
an effective search.
- By May 2000, 2 million
participants had downloaded the software, making SETI@home the world's most
powerful supercomputer.
- +1(201) 641-1771
- A little program
created to "spy" on (or pay attention to) the progress and performance of
the SETI@home client.
- Evolutionary developmental
biology, also known as "evo-devo," studies the genes that control embryonic
development in different organisms to answer questions about evolution.
- Sagan and Mayr debated
whether humans were unique in the universe, or if extra-terrestrial life
could exist. Dr. Mayr took the point of view that uniqueness characterized
human intelligence, while Dr. Sagan focused on the belief that intelligent
life could and did exist elsewhere in the universe.
- Tom Pierson.
- With support from NASA
and The Planetary Society, Paul Horowitz spent a year as an NRC postdoctoral
fellow at Ames Research Center (1981-82), where he and colleagues from Stanford
University and NASA built a high-resolution hardware spectrometer that
could handle in real time the kind of signal processing that was used in
the earlier Arecibo search.

- Schwartz & Townes
- SETI@home offers a newsletter.
- N = R* × fp ×
ne × fl × fi × fc × L
- The radio signals are
in a form of narrow-band signal. They are known to be a few Hertz
or less wide and pack a lot of energy into a small amount of spectral space.
- A radio telescope collects
radio waves in its parabolic dish and concentrates them in a focal point
where a receiver is placed.
- There are several advantages:
(1) Several stars can be examined simultaneously, rather than looking
at one star at a time. (2) More "pixels" can be generated on the sky
at once. (3) Easy to expand an array by merely buying additional antennas
and connecting them into the system.
- Weak signal communication
is a form of communication where radio signals have signal strength levels
that are close to or partially embedded in the natural noise. It is
believed that SETI signals are likely to be detected as weak signal communication.
- Because the stars that
scientists are focusing their search around are too far away for any of
our rockets to reach. It would take 60,000 years for one of our rockets to
reach Alpha Centauri, the closest star system to us.
- Project Phoenix
- A stable orbit, an atmosphere,
liquid water, and a climate regulated by plate tectonics.
- Approximately one per year.
- Projects Argus, Beta and
Phoenix, SETI@home, and Southern SERENDIPITY.
- $20.
- Earth-Moon-Earth communications.
- Mike Fox and Mike Fremont.
- Jodrell Bank Observatory.
- The Ohio State Radiotelescope
is larger than three football fields in size, and it is equivalent in sensitivity
to a circular dish 175 feet in diameter.
