Some Of The Discoveries Made At The Arecibo Observatory
The Arecibo Observatory opened its doors for business in 1963, supported by the National Science Foundation as one of their main stakeholders. The NSF sponsors research in various sciences, as they do too in cellular and organismal biology.Their first discovery of importance to the global scientific community was that the planet Mercury rotated at the rate of 59 days. Prior to this discovery, astronomers had believed that it rotated in 88 days. Scientists had to rethink their previous ideas, and this is what is happening every year that the Observatory is in operation. When new discoveries are made, recalculations and configurations have to be done in order for scientists to better understand the way the universe operates.
One very early morning in 1979 scientist noticed a large anomalous traveling ionosphere disturbance, or an upper atmosphere wave, moving in a southeast to a northwest direction. This was a phenomenon that no observer had seen before. It transpired that what they had witnessed was in fact a nuclear air blast over the Indian Ocean. However, it took twenty years for the scientists to be vindicated, as the US administration decided at the time that there was insufficient evidence to support the belief that a nuclear test had taken place. The Vela satellite which had recorded the blast was deemed past its sell-by date for the data it relayed to be accurate, as it could not give adequate data for analysis. It was not until 20th April 1997 that the South African deputy prime minister, Aziz Pahad, confirmed that a nuclear test had indeed taken place near South Africa’s Prince Edward Island on September 22nd 1979. The scientists at Arecibo had been correct in their analysis of the phenomenon that they had witnessed and had remained convinced that they what they had witnessed was the result of a nuclear blast, despite being discredited at the time. After Pahad’s statement to an Israeli daily newspaper, the US embassy in Pretoria South Africa confirmed the report. Israel had helped South Africa develop a nuclear weapon in return for 550 tons of raw uranium and other assistance. The disclosure might never have been made, and the scientists at Arecibo might never have been vindicated in their correct analysis of the phenomenon they had seen.
During the period 1968-1969 in the early years of the Observatory’s operations, scientists discovered radio pulses at the center of the Crab Nebula and found a period pulsar of 33ms.Up until that time a pulsar had been suggested in theories but at the Observatory, scientists found proof of their existence. Of course, later they discovered the first pulsar in a binary system which led to confirmation of Einstein’s general theory of relativity and a Nobel Prize in Physics for the two astronomers who had found the pulsar, Hulse and Taylor.
The observatory has helped scientific discovery and understanding immensely, and if it were to have a more limited functioning this could mean that we will be much slower to make new discoveries. The observatory has become significantly important in understanding and implementing scientific methods, it shows positive trend in the technology. The System expects to be improved with the passage of time for human assistance.
