Neutron stars are the result of a supernova explosion, which is when a star reaches the end of its life and dies. The original object in a Supernova explosion is called the progenitor which either collapses to a neutron star or black hole, or it is completely destroyed. SN 2010kd The SN 2010kd is a super-luminous supernova located 1.5 Giga Light Years away from our solar system and was discovered embedded in a dwarf host galaxy towards the Leo Constellation. A Supernova is the largest explosion of a … NEW DELHI: Researchers at Indian Institute of Technology (IIT), Guwahati, claim to have found important clues to understand the death of massive stars and have also revealed the problems with the existing models. Supernova. A supernova happens where there is a change in the core, or center, of a star. Massive stars enrich the interstellar medium with carbon before the supernova explosion, when they also experience powerful stellar winds. Burnell discovered pulsars, which are rapidly rotating neutron stars that emit radio-frequency pulses, on November 28, 1967. The explosion of a nearby star, occurred between Devonian and Carboniferous periods, could have caused a mass extinction event that took place 359 million years ago. A supernova happens where there is a change in the core, or centre, of a star. Since then the supernova remnant — a structure resulting from the explosion of a star in a supernova — has expanded 60 light-years from its centre. The supernova explosion took place between 10,000 to 20,000 years ago caused by a dying star breaking apart which is 20 times larger than our Sun. Researchers at the Arayabhatta Research Institute of Observational Sciences (ARIES) Nainital an autonomous research institute under the Department of Science and Technology (DST) Govt. Latest top 50 UPSC month current affairs are published in question and answer format which are reviews from Hindu, you can also download PDF file ... they go with a spectacular bang known as the supernova. Context. • The report suggests that while Betelgeuse’s behaviour is out of the ordinary, it doesn’t mean that an eruption is imminent since astronomers predict the star to blast sometime (supernova explosion, which is the largest explosion to take place in space) in the next 100,000 years or so. Neutron stars– PRESS INFORMATION BUREAU (PIB) IAS UPSC – 28th November to 5th December – 2020; GS-2. 13 Jan 2021. It exploded with a larger velocity but decayed slower than other similar supernovae. A supernova is the explosion of a star. It is the largest explosion that takes place in space. In this article we will discuss Theories of origin of the earth which is the second article of the geomorphology course of Geography Optional UPSC, therefore, first of all, you should read the first article (Universe and Solar system) later on hop on this article.. Today you’re going to learn various theories of the origin of the earth. A super-luminous supernova is a special type of stellar explosion that ejects 10 times or more energy than a regular supernova. of India found that SN 2010kd, a super-luminous supernova stands out with the amount of mass as well as Nickel ejected during explosion, which is much more than seen in case of normal core … It is the largest explosion that takes place in space. SN 2010kd is a super-luminous supernova which ejected huge amounts of mass and Nickel during explosion. ... (UPSC CSE 2019) | Mock Interview – Watch On YouTube. Neutron stars. A change can occur in two different ways, with both resulting in a supernova. The amount of ejection was much more than seen in case of normal core-collapse supernovae, which indicates that the related star evolution might be different. Supernova- A supernova is the explosion of a star. A Supernova could have trigger the late Devonian extinction, according to a new study. ... because they power the explosion and provide an early warning signal that allows scientists to look in the right direction before the supernova explosion takes place. ; GS-2 enrich the interstellar medium with carbon before the supernova explosion, which is a. ; GS-2 enrich the interstellar medium with carbon before the supernova explosion, when they also experience stellar!
