30m Telescope
The Thirty Meter Telescope is a telescope project that is being built at the TMT Observatory, which is situated at the top of Mauna Kea, on Big Island, Hawaii. There are already several telescopes at the top of Mauna Kea, which at 14,000 feet is often above the clouds, in the middle of the Pacific Ocean with minimal light pollution.
The telescope will be of the Ritchey-Chretien type, which is a Cassegrain telescope that has a hyperbolic primary mirror and hyperbolic secondary mirror. This is the most common type of telescope used in professional astronomy. The TMT will also feature optical and infrared observing, "with wavelengths of interest ranging from 310 nanometers in the ultraviolet to 28 microns in the infrared. The telescope is comprised of a large number of different systems within the same facility, including mechanical assemblies, control systems and distribution systems. The actual summit enclosure is not considered to be part of the telescope (TMT, org, 2014).
The telescope is a joint venture between a number of different bodies, including the California Institute of Technology, Chinese Academy of Sciences, Japan's National Institute of Natural Sciences and National Astronomical Observatory and the University of California, with contributions from Canada and India...
Astronomy The Terrestrial planets are defined as rocky planets or telluric planets, and they are Mercury, Venus, Earth and Mars. These planets have a lot of similarities that allow them to be grouped together, especially in contrast to the Jovian or gas planets. The telluric planet is one given type of planet, defined as one that is primarily composed of rocks and heavy metals. Thus, the composition of these planets is
Of those 1,235, 68 are estimated to be Earth-size; 288 are super Earth-size; 662 are Neptune-size; 165 are the size of Jupiter, and 19 are larger than Jupiter (Science Daily). Of the 54 planet candidates that have been found in the habitable zone, five are near Earth-size. The other 49 left in the habitable zone range from super-Earth-size (up to twice the size of the Earth) -- to larger than
The first telescope is a 10 m telescope that is planned to be located at the L2 Lagrangian point 1.5 million kilometers past the orbit of the Earth. The second telescope is a 2 m telescope that is planned to be placed on the far side of the moon (average distance to the moon is 380,000 km from the Earth). (a). Which telescope will have the greater light gathering power (10
Astronomy Carbon Dioxide Snow on Mars The research and mission reported by this article regards unique weather patterns occurring on Mars. According to data gathered by the Phoenix Mars lander and the Mars Reconnaissance Orbiter data, there are clouds of water vapor on Mars and there is the only known stance of carbon dioxide snow falling in this solar system. The research on this phenomenon was first published in the Journal of
They appear as dark circles on the sun's surface. Ex. 6: The lifecycle of a star is determined by its mass. A typical star will follow the main sequence, become a yellow star like the Sun, and die as a Red Giant and then settle as a White Dwarf. A black hole is an area that has had gravity pull in on itself due to a supermassive explosion. Black holes
Astronomy Explain how the Hertzsprung-Russell diagram is constructed of the four main groupings of stars. Identify characteristics of the four main groupings of stars on the diagram. How are the axes of graph labeled? The Hertzsprung-Russell diagram is much like a common graph used in mathematical subjects like algebra and other mathematical domains. Like any graph, there is an X axis and a Y axis with each axis representing different majors traits
