SANTIAGO, May 9 2010 (IPS) - The construction of the world’s largest telescope in the northern region of Antofagasta could make Chile an international leader in astronomy research and provide a launch pad for developing other scientific disciplines.
The Ego’s new 1.5-billion-dollar jewel, the European Extremely Large Telescope (E-ELT), is able to detect atmospheres. The optical-infrared telescope will have a primary mirror 42 metres in diameter.
“Between now and the end of the decade, Chile will possess the greatest number of observation instruments and is going to become a major global astronomy centre,” predicted Mario Hamuy, director of the astronomy department at the University of Chile, in a Tierramérica interview.
The work of Hamuy and other Chilean and foreign astronomers in the specialisation of supernova stars contributed to the discovery of the universe’s accelerating expansion.
“Dark energy” is thought to be responsible for this phenomenon. This hypothetical form of energy is believed to constitute 70 percent of the universe’s mass-energy. The E-ELT could play a crucial role in determining the origin of this mysterious energy, said the Chilean scientist.
But also taken into consideration were the construction and operating costs, and the “synergies” with the other ESO sites in northern Chile: the Paranal and La Silla observatories and the ALMA (Atacama Large Millimetre Array), which the 14-nation European entity will complete in 2012 in collaboration with other institutions.
In addition to Cerro Armazones, located 1,200 km north of Santiago, the Chilean government had proposed three other sites for the “world’s biggest eye on the sky” that will begin operating in 2018.
Chile is also home to the Cerro Tololo observatory, operated by a consortium of private U.S. universities, Las Campanas observatory, of the also private Carnegie Institution for Science, based in Washington DC.
“The national astronomy society has developed a great deal in the last 15 years, especially because we have access to 10 percent of the observation time at all the foreign telescopes in the country,” the president of the Chilean Astronomy Society, Leopoldo Infante, told Tierramérica.
Chile, with a population of 17 million, in the last few decades went from just a couple dozen astronomers to around 100 today, who publish their research in the most prestigious scientific journals around the globe.
The government has the opportunity to transform the country, with just a “modest investment,” into “a leader in astronomy research,” said Hamuy. Chile needs to focus resources on the “design and construction of instruments” for its own observation activities, he said.
“What is missing is the phase of technology transfer, for which we need more state incentives,” agreed Infante, also director of the Astro-Engineering Centre at the Catholic University, and part of the discovery of the most distant galaxy from Earth.
The government seems to have gotten the message: the interim president of the National Commission on Scientific and Technological Research, María Elena Boisier, said a funding plan is in the works for developing astronomy instruments as well as engineering and information technologies related to the E-ELT.
Juan Asenjo, president of the Chilean Academy of Sciences, believes the achievements in the field of astronomy “should be extrapolated to other scientific disciplines as well,” such as geophysics, experimental physics and geology.
“Chilean society, politicians and entrepreneurs have no idea that first-rate science is taking place in Chile, and there is no awareness that scientific developments lead to a higher quality of life,” said Asenjo, 2004 winner of the National Applied Sciences Prize.
This perception, in his opinion, stands in the way of channelling more resources in that direction.
Asenjo noted the work of Chilean seismologists, who in the 1990s predicted the occurrence of a devastating quake in the central and southern regions of the country, just like the Feb. 27 earthquake that caused billions of dollars in destruction. Their work did not have the dissemination or impact they deserved.
The new Chilean president, Sebastián Piñera, of the right-wing Coalition for Change, promised to increase investment in research and development from the current 0.7 percent gross domestic product to 1.2 percent by the end of his term in 2014.
