We know bacteria live in caves that have little or no oxygen. Interesting article here about caves in the Bahama's that have life in poisonous clouds of hydrogen sulfide. There is also a belief about silicon based life forms which could be found on other planets and moons. Scientist are begging to get some sort of probe around and on Titan. IMO, there is alien life in our solar system. Not intelligent but life.
We also have telescopes that have found numerous planets that are similar to Earth. We may never know if they have life but what holds true on Earth probably holds true everywhere else. Where there is 1 , there is another, and another, and another, etc...
shackfu, I lived in P.R. almost 3 years , this is a great place to visit
and was the location for the shooting of the Charlie Sheen Sci-Fi movie "Arrival"
The Arecibo Observatory is a radio telescope near the city of Arecibo in Puerto Rico. It is operated bySRI International under cooperative agreement with the National Science Foundation.[2][3] Theobservatory is also called the National Astronomy and Ionosphere Center, although "NAIC" refers to both the observatory and the staff that operate it.[4]
The observatory's 305 m (1,000 ft) radio telescope is the largest single-aperture telescope (cf. multiple aperture telescope) ever constructed. It carries out three major areas of research: radio astronomy,aeronomy (using both the 305 m telescope and the observatory's lidar facility), and radar astronomyobservations of Solar System objects. Scientists who want to use the telescope submit proposals, which are evaluated by an independent board.
Visually distinctive, the telescope makes frequent appearances in motion picture and television productions. The telescope received additional international recognition in 1999 when it began to collect data for the SETI@home project.
Research and discoveries
Many significant scientific discoveries have been made using the Arecibo telescope. On April 7, 1964, shortly after it began operations,
Gordon Pettengill's team used it to determine that the
rotation rate of
Mercury was not 88 days, as previously thought, but only 59 days.
[16] In 1968, the discovery of the periodicity of the
Crab Pulsar (33 milliseconds) by Lovelace and others provided the first solid evidence that
neutron stars exist.
[17] In 1974,
Hulse and
Taylor discovered the first binary pulsar
PSR B1913+16,
[18]an accomplishment for which they later received the Nobel Prize in Physics. In 1982, the first
millisecond pulsar,
PSR B1937+21, was discovered by
Donald C. Backer,
Shrinivas Kulkarni,
Carl Heiles, Michael Davis, and Miller Goss.
[19] This object spins 642 times per second, and until the discovery of
PSR J1748-2446ad in 2005, it was the fastest-spinning pulsar known.
In August 1989, the observatory directly imaged an asteroid for the first time in history: 4769 Castalia.[20] The following year, Polish astronomer Aleksander Wolszczan made the discovery of pulsar PSR B1257+12, which later led him to discover its three orbiting planets and a possible comet.[21][22] These were the first extra-solar planets discovered. In 1994, John Harmon used the Arecibo radio telescope to map the distribution of ice in the poles of Mercury.[23]
In January 2008, detection of prebiotic molecules methanimine and hydrogen cyanide were reported from Arecibo Observatory radio spectroscopy measurements of the distant starburst galaxy Arp 220.[24]
The Arecibo message
In 1974, the
Arecibo message, an attempt to communicate with potential
extraterrestrial life, was transmitted from the radio telescope toward the
globular cluster M13, about 25,000 light-years away.
[25] The 1,679
bit pattern of 1s and 0s defined a 23 by 73 pixel
bitmap image that included numbers, stick figures, chemical formulas, and a crude image of the telescope itself.
[26] Terrestrial aeronomy experiments include the
Coqui 2 experiment.
Old joke:
NASA, in an effort to make contact with civilizations on other planets, sent "Voyager" into space packed with cultural items and a planetary map showing our location. There are great novels, reproductions of famous artwork, music recordings, histories of mankind, movies and assorted other things on board. A few years later a missile lands on earth. It contains an envelope and, inside, a piece of paper with strange markings on it.
The government pulls together a team of the greatest scientists and linguists to figure out what it says. After six months, the lead researcher calls the president and says they have broken the code. The president says, “Great, what is the message?” The researcher pauses and says, “They want us to send more Chuck Berry.”
