Subaru (telescope)
is the telescope of the National Astronomical Observatory of Japan, located at the Mauna Kea Observatory on Hawaii. It is named after the open star cluster known in English as the Pleiades. It had the largest monolithic primary mirror in the world from its commissioning until 2005. Overview The Subaru Telescope is a Ritchey-Chretien reflecting telescope. Instruments can be mounted at a Cassegrain focus below the primary mirror; at either of two Nasmyth focal points in enclosures on the sides of the telescope mount, to which light can be directed with a tertiary mirror; or at the prime focus in lieu of a secondary mirror, an arrangement rare on large telescopes, to provide a wide field of view suited to deep wide-field surveys. In 1984, the University of Tokyo formed an engineering working group to develop and study the concept of a telescope. In 1985, the astronomy committee of Japan's science council gave top priority to the development of a "Japan National Large Teles ...

Chichi-jima
, formerly known as Peel Island, is the largest island in the Ogasawara Islands, Ogasawara archipelago. Chichijima is about north of Iwo Jima. The island is within the political boundaries of Ogasawara, Tokyo, Ogasawara Village, Ogasawara Subprefecture, Tokyo, Japan. 2,120 people live on its land area of . History The first European discovery of the Ogasawara Islands is said to have taken place in 1549 by the Spain, Spanish explorer Bernardo de la Torre. Archeological excavations show that Micronesian people, Micronesians lived on the island in the past, though no details are yet known. The Tokugawa Shogunate dispatched an expedition in 1675 and made a map of the island. It remained uninhabited until May 1830. Nineteenth century Western ships visited the island on several occasions in the 19th century, including: *The Frederick William Beechey, Beechey Pacific expedition on HMS Blossom (1806), HMS ''Blossom'' in 1827 *Naturalist Heinrich von Kittlitz in 1828 with the Russia ...

Tokyo Photoelectric Meridian Circle
The Tokyo Photoelectric Meridian Circle (PMC) is a meridian circle that observes and records the positions of stars and planets, which are then reported in the PMC catalogs. Meridian circle The Tokyo Photoelectric Meridian Circle is a fully automated photoelectric meridian circle at the Mitaka campus of the National Astronomical Observatory of Japan (formerly of the Tokyo Astronomical Observatory) in Tokyo, Japan. It was manufactured by Carl Zeiss Oberkochen, Germany, and installed in Mitaka in 1982. The telescope is equipped with a double-slit photoelectric micrometer, a photomultiplier with a photon counting device, and a set of filters. Systematic observations with the PMC began in December 1985 for about 33,000 stars selected from several source catalogs. The results of the observations were divided into sequential groups according to the observation years and reduced into a corresponding annual catalog. Each annual catalog contains the positions of several thousand stars. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atacama Desert
The Atacama Desert ( es, Desierto de Atacama) is a desert plateau in South America covering a 1,600 km (990 mi) strip of land on the Pacific coast, west of the Andes Mountains. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, just behind some very specific spots within the McMurdo Dry Valleys as well as the only hot true desert to receive less precipitation than the polar deserts, and the largest fog desert in the world. Both regions have been used as experimentation sites on Earth for Mars expedition simulations. The Atacama Desert occupies , or if the barren lower slopes of the Andes are included. Most of the desert is composed of stony terrain, salt lakes (''salares''), sand, and felsic lava that flows towards the Andes. The desert owes its extreme aridity to a constant temperature inversion due to the cool north-flowing Humboldt ocean current and to the presence of the strong Pacific anticyclone. The most arid re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravitational Wave Detector
A gravitational-wave detector (used in a gravitational-wave observatory) is any device designed to measure tiny distortions of spacetime called gravitational waves. Since the 1960s, various kinds of gravitational-wave detectors have been built and constantly improved. The present-day generation of laser interferometers has reached the necessary sensitivity to detect gravitational waves from astronomical sources, thus forming the primary tool of gravitational-wave astronomy. The first direct detection of gravitational waves made in 2015 by the Advanced LIGO observatories, a feat which was awarded the 2017 Nobel Prize in Physics. Challenge The direct detection of gravitational waves is complicated by the extraordinarily small effect the waves produce on a detector. The amplitude of a spherical wave falls off as the inverse of the distance from the source. Thus, even waves from extreme systems such as merging binary black holes die out to a very small amplitude by the time they ...

Mauna Kea
Mauna Kea ( or ; ; abbreviation for ''Mauna a Wākea''); is a dormant volcano on the island of Hawaii. Its peak is above sea level, making it the highest point in the state of Hawaii and second-highest peak of an island on Earth. The peak is about higher than Mauna Loa, its more massive neighbor. Mauna Kea is unusually topographically prominent for its height: its wet prominence is fifteenth in the world among mountains, at ; its dry prominence of is second in the world, only after Mount Everest This dry prominence is greater than Mount Everest's height above sea level of , and some authorities have labelled Mauna Kea the tallest mountain in the world, from its underwater base. It is about one million years old and thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring v ...

KAGRA
The Kamioka Gravitational Wave Detector (KAGRA), is a large interferometer designed to detect gravitational waves predicted by the general theory of relativity. KAGRA is a Michelson interferometer that is isolated from external disturbances: its mirrors and instrumentation are suspended and its laser beam operates in a vacuum. The instrument's two arms are three kilometres long and located underground at the Kamioka Observatory which is near the Kamioka section of the city of Hida in Gifu Prefecture, Japan. KAGRA is a project of the gravitational wave studies group at the Institute for Cosmic Ray Research (ICRR) of the University of Tokyo. It became operational on 25 February 2020, when it began data collection. It is Asia's first gravitational wave observatory, the first in the world built underground, and the first whose detector uses cryogenic mirrors.
