Sagittarius A*'s Image By Ramesh S Krishna Blog no:27 Date: 13th May, 2022 What is a black hole? A black hole is a dense area in space where the density of items inside it is infinite. Its gravity is super strong that not even electromagnetic particles like Light cannot escape. The point of no return is called the Event horizon . The black hole doesn't emit light in the visible spectrum. So, never ever have an idea to see the black hole with your eyes. The only way it can be photographed is by Radio or other spectrums. Sagittarius A* is a black hole in the center of our galaxy. It is believed to be a supermassive black hole. It has 44Million Solar masses.  About the image: This image was taken on the 12th of May, 2022. It was collaborated by Nasa's Chandra X-ray telescope , Nuclear spectroscopic telescope, Neil Gehrels Observatory, &  the Event horizon telescope{EHT}. This image will give more data on the accretion disk .   An accretion disk  forms whenever...

Vocabulary  A= Ablation= Melting of the meteorite after entering the atmosphere Absolute magnitude= The brightness of that body from 33 light-years from Earth Accretion Disk= A group of gas orbiting an object. It creates heat & Radiation Accretion= A process when the gas turns into an object Altitude(Horizon)= The height above the horizon Altitude(Rocket)= The height above a specific body Andromeda=  A galaxy located 2.5 million light-years away Antimatter= Matter that is made up of negatively charged particles Apastron= A point in a binary system where both bodies are farthest from each other Aperture= Light observing ...
