Quasars

  Hi everyone, welcome back. In this post we are going to learn about "Quasars". They are mysterious objects that has revolutionized our understanding of the universe in many ways. Everything in this universe is interconnected in some ways we have noticed, other ways we haven't. It will be evident in this post. Let's start! Credits: NASA, ESA and J. Olmsted (STScI) The discovery of these started in the 1950s when they started seeing the sky through radio telescopes which detect radio waves and help in the discovery of objects which cannot be seen through the naked eye or if they are too far and faint to detect. These were discovered due to the use of radio telescopes in 1960. The first discovery was made during "Lunar occultation" (when the moon appears to pass in front of a star, planet, etc.) with the help of "Parks radio telescope". They detected an object which emitted so much radiation but cannot be seen through visible light by further rese...

Nebula

  Hey guys! Welcome back to my blog. From the title, it is evident that this blog is all about nebula.  An introduction about nebula has been given in my previous blog titled- white dwarf ( White Dwarf ). If you haven’t checked it yet, I would recommend you to read that first for a better understanding.  To shoot up your curiosity, let’s see some of their images of different types of Nebula.                   Credit & Copyright:  Imaging -  Josch Hambsch , Processing -  Karel Teuwe This one is known as the Helix Nebula; the closest planetary nebula with the following details:  Diameter : 2.87 light-years Distance : 655 light-years from earth Constellation : Aquarius . Credit:  H. Bond et al.,  Hubble Heritage Team  ( STScI  /  AURA ),  NASA Below is an image of the Ring Nebula taken by the Hubble telescope.  It has the following details: Diameter :  2....

White Dwarf

Image
  Hey! Welcome back to my blog! Have you heard about a white dwarf in space?  Probably yes! You might have heard the recent news that astronomers have discovered a star that is as small as a moon but with more mass than the sun. This star is a white dwarf!! Now, are you more curious about it?  A low or medium mass star (with a mass less than about 8 times the mass of our Sun) will become a white dwarf. The Burned-out core of a star is a white dwarf. Let’s take an example of our sun to understand what white dwarfs are and how they are formed. Formation of a white dwarf: Our sun produces heat, for producing heat they need fuel. So like how we use LPG or diesel for fuel, our sun uses hydrogen and helium as its fuel. The actual process taking place is a fusion of hydrogen with heat to give helium.                     HYDROGEN        ...

Classifications of neutron stars

Image
  Hello guys! Welcome back to AstroMe!   So, in my last blog, we learned about NEUTRON STAR. Before reading this post. I recommend you to read my previous post as this is a continuation. Check out Neutron Star .   Neutron stars can be mainly classified into two types:  magnetars  and  pulsars . Without any delay, let’s see about the types in detail.    MAGNETAR: They have  very strong   electromagnetic energy  from where they get their name. They  rotate more slowly  in comparison to all the neutron stars. For example, they rotate just three or four times in 20 seconds.  They generate very strong  X Rays  and  gamma rays.   Magnetars can be  active or inactive.   They are considered to be active when all the above points can be seen   They are inactive when they  lose their fuel and magnetic energy.     ...
