THE UNICORN : CLOSEST BLACK HOLE TO EARTH

The black hole absorbing light

Firstly we need to know about black holes. Black hole are those holes which formed when two stars collapse each other when they live it’s complete life. Only black hole have capacity to absorb light completely without emitting any particle of light. They are small in size as compared to stars but having mass greater than star and also having higher density than a star.

THE UNICORN : CLOSEST BLACK HOLE TO EARTH 


Sir Tharindu Jayasinghe a doctoral student in astronomy at Ohio state found the closest black hole to the earth. It have nickname “THE UNICORN”.  The Unicorn is located about 1500 light years from Earth. This may be the smallest known black hole in ‘The Milky Way Galaxy’ and closest to our solar system. The mass of this black hole is 3 solar masses. This black hole is located right next to red giant star called V723 Mon in the constellation of Monoceros. Speed of Unicorn is approx. 1100,000 mph about 230 million light years from Earth. This is not dangerous for earth. Scientist believe that it would not reach to Earth due to the distance between black hole and earth.

About James Webb Space Telescope

JAMES WEBB SPACE TELESCOPE  JAMES WEBB SPACE TELESCOPE Firstly we need to know about the space telescope. It is a telescope which is placed in outer space and used to observe astronomical objects. And also used to study different types of light phenomenon like Aurora lights and to study hottest and most explosive object. Currently, NASA had launched a space telescope named as JAMES WEBB SPACE TELESCOPE [JWST] . It was made by international collaboration among NASA, the European Space Agency, and the Canadian Space Agency. It works as a replacement of Hubble Space Telescope. JWST was launched on 25 December 2021 on Arian Flight VA256. Firstly it was named as Next Generation Space Telescope and after some time name change to James Webb Space Telescope. There are some properties of JWST are Mass- 6161.4kg , Dimensions- 20.197m×14.162m , Power- 2KW. It operates in a Halo orbit, circling around a point in space known as the Sun-Earth Lagrange Point, approx 1500000km beyond Earth orbit aroun

Lifecycle of a star : Birth to Death

STARS AND PLANETS  Star A star is a luminous and biggest object in the universe that emit light naturally. Sun is also a star. The study of birth , life and death of a stars is called stellar evolution. First stage in the birth of star is called protostar and the death of star is called supernova .  FORMATION OF A STAR BY CLOUD OF DUST How stars are formed ? Stars are made by cloud of gases and dust that scattered throughout the galaxies. The cloud of dust is called the orion nebula . As gravitational force of attraction applied on cloud they collapses and when cloud collapse the material at the center get heat up so that all stars and planet have high temperature at core. A star build by continuous process of gravitational pull cloud collapse to make its size bigger. The size of star (or mass of a star) reaches from  15 to 130 solar masses . At center the temperature gets extremely high, it tigger the fusion reaction. All the material that has fallen in then evolves into a hot and br

AURORA: THE LIGHT OF POLES

Space view of Aurora Lights  Firstly, we need to know about the aurora. Auroras are the light which is produced naturally by collision of charge particles with gasses molecules present in the atmosphere. Predominantly sun in high latitude region like arctic and Antarctic. This light produces always at poles because magnetic field of earth is stronger on the poles and also the density of magnetic field lines is high there. Thus, a large number of charge particles found at the poles. The charge particles collide with the gasses to making them excited that cause  coloured visible light. When the charge particle collides with oxygen molecules then green light is emitted mostly but sometimes it produce red light and when collides with nitrogen molecules then more pink , orange or red colours emitted. Different types of Aurora Light seen on different places  These light appearing near the North Pole and South Pole. Scientist name these light as at North Pole light called “ Aurora borealis
