Govind Swarup
Govind Swarup (March 23, 1929 – September 7, 2020) was a pioneer in radio astronomy. In addition to research contributions in multiple areas of astronomy and astrophysics, he was a driving force behind the building of "ingenious, innovative and powerful observational facilities for front-line research in radio astronomy". Swarup was the key scientist behind concept, design and installation of the Ooty Radio Telescope (Ootacamund, India) and the Giant Metrewave Radio Telescope (GMRT) near Pune. Swarup was the founding director of the National Centre for Radio Astrophysics (NCRA) at the Tata Institute of Fundamental Research (TIFR). Under his leadership, a strong group in radio astrophysics was built at Tata Institute of Fundamental Research that is comparable to the best in the world. He published over 125 research papers, edited 4 books, and held at least two patents. He contributed to the fields of solar radio emission, radio galaxies, quasars, pulsars, interplanetary scint ...

Ophiuchus Supercluster Explosion
NeVe 1 is a supergiant elliptical galaxy and the central, dominant member of the Ophiuchus Cluster, about 411 million light-years away from Earth behind the Zone of Avoidance region of the sky. It is notable for being the host galaxy of the Ophiuchus Supercluster eruption, the most energetic astronomical event known. Observation history Despite being in the relatively nearby, large Ophiuchus Cluster, due to its location behind the Milky Way galactic disc relative to the Earth's perspective (known as the Zone of Avoidance), the majority of the cluster including NeVe 1 are invisible to the naked eye, such that it can only be observed in wavelengths beyond the visible spectrum, such as X-rays and infrared. When first observed in 1985 it was initially thought to be a planetary nebula within the large, star-forming Rho Ophiuchi cloud complex. In a catalogue published by the German astronomers Thorsten Neckel and Hans Vehrenberg using data retrieved from the Palomar Observator ...

Narayangaon
Narayangaon is a town in the Junnar taluka of the Pune district of Maharashtra state, India. Water is abundant because of its proximity to the major dams, the western ghats, and the Sahyadri mountain range. Geography Narayangaon is located 656 m (2,152 ft) above sea level on the western margin of the Deccan plateau. It is situated on the leeward side of the Sahyadri mountain range, which forms a barrier from the Arabian sea. Narayangaon is on the bank of the river Meena. A wide hill range in the south separates the town from the adjoining Ambegaon taluka. Narayangaon can be reached from major cities via road. It is situated on Pune-Nasik National Highway 50. It is 77 km north of Pune, 132 km south of Nasik and around 176 km east of the state capital, Mumbai.

Radio Telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supernovae
A supernova is a powerful and luminous explosion of a star. It has the plural form supernovae or supernovas, and is abbreviated SN or SNe. This transient astronomical event occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the ''progenitor'', either collapses to a neutron star or black hole, or is completely destroyed. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months. Supernovae are more energetic than novae. In Latin, ''nova'' means "new", referring astronomically to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous. The word ''supernova'' was coined by Walter Baade and Fritz Zwicky in 1929. The last supernova to be directly observed in the Milky Way was Kepler's Supernova in 1604, appearing not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical Observatories In India
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

Interferometric Telescopes
Interferometry is a technique which uses the ''interference'' of superimposed waves to extract information. Interferometry typically uses electromagnetic waves and is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, velocimetry, optometry, and making holograms. Interferometers are devices that extract information from interference. They are widely used in science and industry for the measurement of microscopic displacements, refractive index changes and surface irregularities. In the case with most interferometers, light from a single source is split into two beams that travel in different optical paths, which are then combined again to produce interfere ...
