What is the tremendously large telescope?

The mostly large telescope (OWL) is a conceptual design of the European Southern Observatory (ESO), which will create a telescope of $ 1.2 billion with a lens of $ 100 (328 ft), which would be the largest optical telescope. Since then, the scale has decreased to the lens of 60 meters (200 ft). The target date for completion is around 2019 and the plain east of Antofagast is considered Chile for this place because of their year -round clear sky and high altitude. Although some interferometric projects will have a greater angular resolution than OWL, it will have greater light collection and display capacity, allowing sharper images of weak and distant astronomical objects.

Since there is no technology that produces a lens of 60 meters, any lens would have to be segmented for this purpose. Get an idea of ​​why this is called a tremendously large Telerozsah, imagine a mirror with a 20 -storey building diameter. Due to its huge size, cost and complexity, it is no surprise thatThe feasibility advice for ESO feasibility has decided that OWL should be placed on the rear burner of its priority list.

Although OWL can still see daylight, the ace is currently focusing on the European extremely large telescope, a reduced binoculars with a lens of 40 meters, for approximately $ 800 million USD (USD). This would still be accurate enough to solve the atmosphere of extrasolar planets, which would allow us to perform spectroscopic analysis to determine the possible presence of organic compounds.

Using a technique called adaptive optics, which has been developed to reduce atmospheric flashing, owls or something similar, it will overcome the space observatory as the largest windows in the world into space. Because it is so expensive to initiate payloads into space and relatively cheaper to build a very large telescope on Earth, it is likely that thisdominates astronomy until the starting costs can be triggered.
