Mount Abu InfraRed Observatory
The Mount Abu InfraRed Observatory (MIRO) is located near the town Mount Abu in the state of Rajasthan, India. The observatory is at an altitude of 1680 metres and is adjacent to Guru Shikhar, highest peak of the Aravalli Range. The 1.2 m infrared telescope at It is the first major facility in India specifically designed for ground-based, infrared observations of celestial objects. Further the low amount of precipitable water vapour (1–2 mm during winter) at Guru Shikhar makes it a good site for the infrared telescope observations. The site has been found to be good (about 150 cloud free nights per year) for astronomical observations. Location The Observatory is located near Guru Shikhar, the highest peak of the Aravalli Range at an altitude of 1680 metres. Mount Abu is about 28 km from the Abu Road railway station and about 240 km from Ahmedabad. MIRO is operated by the Astronomy & Astrophysics Division of the Physical Research Laboratory, Ahmedabad.

Guru Shikhar
Guru Shikhar, a peak in the Arbuda Mountains of Sirohi district in Rajasthan, is the highest point of the Aravalli Range and Rajasthan. It rises to an elevation of . It is 75 km from Sirohi city, the district headquarter and 15 km from Mount Abu and a road from there leads almost to the top of the mountain. It is named ''Guru- Shikhar'' or 'the peak of the guru' after Dattatreya, an incarnation of Vishnu, andof a cave at the summit contains a temple dedicated to him, plus one edicated his mother, Anasuya, wife of sage Atri nearby. Adjacent to the temple is the Mt Abu Observatory operated by the Physical Research Laboratory.

Mount Abu
Mount Abu () is a hill station in the Aravalli Range in Sirohi district of the state of Rajasthan in western India.The mountain forms a rocky plateau 22 km long by 9 km wide. The highest peak on the mountain is Guru Shikhar at above sea level. It is referred to as 'an oasis in the desert' as its heights are home to rivers, lakes, waterfalls and evergreen forests. The nearest train station is Abu Road railway station 28 km away. History The ancient name of Mount Abu is Arbuda. In the Puranas, the region has been referred to as ''Arbudaranya'' ("forest of ''Arbhuda''") and 'Abu' is a diminutive of this ancient name. It is believed that sage Vashistha retired to the southern spur at Mount Abu following his differences with sage Vishvamitra. There is another history story according to which a serpent named "Arbuda" saved the life of Nandi (Lord Shiva's bull). The incident happened on the mountain that is currently known as Mount Abu and so the mountain is named "Arb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rajasthan
Rajasthan (; lit. 'Land of Kings') is a state in northern India. It covers or 10.4 per cent of India's total geographical area. It is the largest Indian state by area and the seventh largest by population. It is on India's northwestern side, where it comprises most of the wide and inhospitable Thar Desert (also known as the Great Indian Desert) and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej- Indus River valley. It is bordered by five other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest. Its geographical location is 23.3 to 30.12 North latitude and 69.30 to 78.17 East longitude, with the Tropic of Cancer passing through its southernmost tip. Its major features include the ruins of the Indus Valley civilisation at Kalibangan and Balathal, the Dilwara Temples, a Jain pilgrimage site at Rajasthan's only hill stat ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Aravalli Range
The Aravalli Range (also spelled ''Aravali'') is a mountain range in Northern-Western India, running approximately in a south-west direction, starting near Delhi, passing through southern Haryana, Rajasthan, and ending in Ahmedabad Gujarat. The highest peak is Guru Shikhar on Mount Abu at . The Aravalli Range is arguably the oldest geological feature on Earth, having its origin in the Proterozoic era. The Aravalli Range is rich in natural resources and serves as check to the growth of the western desert. Etymology Aravalli, a composite Sanskrit word from the roots ''"ara"'' and ''"vali"'', literally means the ''"line of peaks"''. Natural history Geology The Aravalli Range, an eroded stub of ancient mountains, is believed to be the oldest range of fold mountains in India.Roy, A. B. (1990).

Infrared Telescope
An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum. All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation. In order to study the universe, scientists use several different types of telescopes to detect these different types of emitted radiation in the electromagnetic spectrum. Some of these are gamma ray, x-ray, ultra-violet, regular visible light (optical), as well as infrared telescopes. Leading discoveries There were several key developments that led to the invention of the infrared telescope: * In 1800, William Herschel discovered infrared radiation. * In 1878, Samuel Pierpoint Langley created the first bolometer. This was a very sensitive instrument that could electrically detect incredibly small changes in temperature in the infrared spectrum. * Thomas Edison used an alternative techno ...

Ahmedabad
Ahmedabad ( ; Gujarati: Amdavad ) is the most populous city in the Indian state of Gujarat. It is the administrative headquarters of the Ahmedabad district and the seat of the Gujarat High Court. Ahmedabad's population of 5,570,585 (per the 2011 population census) makes it the fifth-most populous city in India, and the encompassing urban agglomeration population estimated at 6,357,693 is the seventh-most populous in India.

List Of Astronomical Observatories
This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects of atmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Observatories In Rajasthan
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena.
