Supernova A supernova is a very powerful and luminous explosion at the end of a star's life. The explosion usually ends with a stellar remnant, mainly a black hole or a neutron star. A supernova can sometimes outshine its parent galaxies, releasing energy sometimes equivalent to about 10 billion suns. They shine for some time … Continue reading Random Word #Astronomy
Entropy Entropy refers to the amount of disorder in any given system. The Second Law of Thermodynamics states that entropy (disorder) of any given system only increases or remains constant. It never decreases. For example, take a box and put red balls on the right side and blue balls on the left side. Now shake … Continue reading Random Word #Astronomy
Red Giant Star - A very bright, but very cool huge star. Red Giants are stars that exhaust their hydrogen supply in their core. White Dwarf - A small, dim star. Our Sun will eventually become a white dwarf after shedding its outer layers and forming a planetary nebula with a white dwarf as its … Continue reading Random Word #Astronomy

Some gamma-ray bursts are so incredibly bright that they can actually be seen with the naked eye. One was spotted in March 2008 in the constellation Bootes, even though it was an astonishing 7.5 billion light-years away. Gamma-ray bursts: They are the most energetic form of light. Known as GRBs, they are caused when massive … Continue reading Watch this Space
Amazing Auroras Auroras are the dancing curtains of light that hang in the polar night sky. They happen when charged particles in the solar wind are dragged into the upper atmosphere by Earth's magnetic field. Here they collide with oxygen and nitrogen atoms, releasing flashes of red and green lights. Thanku so much for reading … Continue reading Random Word #Astronomy
