What's so astonishing about Magnetar

A magnetar is a neutron star with a magnetic field greater than any other star in the universe. Same as any other neutron star, a magnetar is approximately 20 km wide and has mass many times the mass of the sun. When a big star undergoes supernova it either becomes a black hole or a  neutron star.

 A magnetar is an exotic type of neutron star which has an enormous mass, it is thought that a tablespoon of the surface of magnetar or neutron star will be equal to the millions of tons of mass of matter.

A magnetar releases a huge amount of electromagnetic radiation and gamma-ray bursts(GRBs) in space when there is a sudden change at its core popularly known as the starquake.

A magnetar roughly 4000 light-years can wipe out the whole life form we know on earth. The magnetic field of the magnetar can damage all electronic circuits, grids, and satellites orbiting the earth, and in no matter of time, our whole communication system will be destroyed furthermore the strong magnetic field of magnetar can disrupt the atoms of our body and will change the bioelectric field of our body and the radiation from it can even change the genetic code of our body.

The nearest magnetar known to us is 11E 1048.1-5937 which is located 9000 light-years away from Earth in the constellation of Carina.

Astronomers on 27 December 2004 detected largest gamma-ray burst further it was found that this GRB was from the magnetar called as SGR 1806-20 which is around 50,000 lightyears away from the earth in the constellation of Sagittarius yet it caused a significant damaged to the earth's ionosphere the ionized layer that surrounds the earth and it is ionized by the solar radiation.

 Although the blast lasted the 1 tenth of the second but it penetrated the atmosphere about down to the 20 Km just slightly above where the aircrafts fly.

Here is the list of five habitable planets we have found so far :-

1.)   Gliese 667Cc  Gliese 667Cc is an exoplanet found on 21 November 2011. It is the member of a triple star system Gliese 667. It is situated in Scorpius constellation approximately 23.61 light-years away from the planet earth.  It has an orbital period of  28 earth days. It is also known as  HD 156384Cc. The exoplanet was found using the radial velocity method.  It is approx 3.7 times heavier than the the earth.  2.)   Kepler-186f It was found on 17 April 2014 by Elisa Quintana. Kepler-186f is an exoplanet orbiting a red dwarf 582 light-years away from the earth. It has a radius of 7,454.1 km with an orbital period of 130 days. It is the first planet with discovered in habitable zone which has a roughly equal radius with that of our earth. The discovery of Kepler - 186f confirms that the habitable planets like our earth exists somewhere in the universe.  Kepler-186f is situated in the constellation of Cygnus. Although the size of Kepler-186f is known but its

Looking deep into supernova

What is a nova? A nova in deep space is a sudden bright flash that varies from some seconds to several years. The novas are often so bright that sometimes they are thought to be the new star is forming up which isn't the case.  All the novas which are observed so far involves a binary star system in which one of a star is a white dwarf and another is any star from the sequence of stars. Novae are mainly seen along the pathway of the milky way galaxy in the constellation of Sagittarius. Illustration of a white dwarf eating it's star The novas are divided into three broad categories:-  1.) Classical nova These are the most often seen type of nova. This happens when the orbital period of both the stars falls short and the white dwarf is close enough to the companion star then the white dwarf starts drawing matter from the companion star onto the surface of itself which forms a dense but low height envelop of gases mainly consisting of hydrogen.  When hydrogen gas i

10 hypothetical stars you don't know about

Blue Dwarf :- It is theorized to be developed from a red dwarf when it looses most of it's hydrogen supply.We haven't found any blue dwarf because red dwarf fuses their hydrogen slowly and currently the universe might not old enough to produce any blue dwarf. Black Dwarf  :- It is thought to be the come from a white dwarf which has exhausted all it's fuel and heat energy which now no further emits radiation and are very hard to detect, fortunately, it do retain it's mass allowing scientists to study it's the gravitational field. It is concluded that the time required for a black dwarf to be formed is longer than the age of the universe thus we haven't found it yet. Frozen star :-There is a probability that this star will form in the distant future when the abundance of heavier metals will be more than it is today which is known as the metallicity of the interstellar medium. It is calculated the temperature of this star will be 273 K or 0-degree celsius. T
