There are two types of competitions conducted by the ASDRC. Two groups of competitors are tested by them. First is Dharmaraja College students. Students in grade 6 and above are tested and rated periodically to keep the standards of their knowledge. The idea beind that is promoting the knowledge as well as building a strong [...]

Lichtenberg was the first Payload Specialist. He flew on Spacelab-1 (STS-9) mission for ten days in 1983, conducted multiple experiments in life sciences, materials sciences, Earth observations, astronomy and solar physics, upper atmosphere and plasma physics. His second flight was ATLAS-1 (STS-45) Spacelab mission for nine days in 1992; conducted 13 experiments in Atmospheric sciences [...]
Laird A. Thompson (born 6 September 1947), is a professor of astronomy at the University of Illinois at Urbana-Champaign. Thompson graduated with a B.A. in both physics and astronomy from the University of California, Los Angeles in 1969. He received his Ph.D. in astronomy from the University of Arizona in 1974. He is professionally associated [...]
reflecting telescope (also called a reflector) is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. [...]
Leuschner Observatory, originally called the Students’ Observatory, is an observatory operated by the University of California, Berkeley. The observatory was built in 1886 on the Berkeley campus. For many years, it was directed by Armin Otto Leuschner, for whom the observatory was renamed in 1951. In 1965, it was relocated to its present home in [...]
Opening in 1964, the Burke Baker Planetarium presents a range of science and astronomy shows. The planetarium is equipped with the SkySkan DigitalSky starfield projector that can simulate stars, planets, comets, nebulous objects and other special effects. in 1998, it was upgraded to fullview, making it the first in the U.S. (and third in the [...]
filter, while the latter category, that of interference or dichroic filters, can be quite complex. Optical filters selectively transmits light having certain properties (often, a particular range of wavelengths, that is, range of colours of light), while blocking the remainder. They are commonly used in photography, in many optical instruments, and to colour stage lighting. [...]
Neo-Babylonian astronomy refers to the astronomy developed by Chaldean astronomers during the Neo-Babylonian, Achaemenid, Seleucid, and Parthian periods of Mesopotamian history. A significant increase in the quality and frequency of Babylonian observations appeared during the reign of Nabonassar (747–734 BC), who founded the Neo-Babylonian Empire. The systematic records of ominous phenomena in astronomical diaries that [...]
Major branches of natural philosophy include astronomy and cosmology, the study of nature on the grand scale; etiology, the study of (intrinsic and sometimes extrinsic) causes; the study of chance, probability and randomness; the study of elements; the study of the infinite and the unlimited (virtual or actual); the study of matter; mechanics, the study [...]
There are several hypotheses for how solar variations may affect Earth. Some variations, such as changes in the size of the Sun, are presently only of interest in the field of astronomy. Changes in total irradiance * Total solar irradiance changes slowly on decadal and longer timescales. * The variation during recent solar magnetic activity [...]
Collectively, amateur astronomers observe a variety of celestial objects and phenomena. Common targets of amateur astronomers include the Moon, planets, stars, comets, meteor showers, and a variety of deep sky objects such as star clusters, galaxies, and nebulae. Many amateurs like to specialise in observing particular objects, types of objects, or types of events which [...]
