  1. Pinwheel Galaxy Image source-google | Image by- Singh.kd81 https://commons.wikimedia.org/wiki/File:The_Pinwheel_Galaxy_-_M101.jpg Even the name of this galaxy makes it very special. It seems to be one of the most beautiful structures in the universe. It also knows as a name of Messier 101 or M 101. It is a face-on spiral galaxy that is 21 million light years away from us. Pinwheel Galaxy was first discovered in 1781 by Pierre Méchain. Such a structure makes it very special and different from other galaxies. Its properties are very similar to the Andromeda Galaxy.

We all must have heard about star clusters. A group of stars is known as a cluster. Clusters can be of two types open cluster, and globular cluster. Some time ago a planet named Methuselah was considered to be the oldest planet in the universe. In fact, the planet was also found as a globularcluster . Omega Centauri is located at a distance of 17,090 light years from us. This cluster is the most massive cluster ever discovered. In a globular cluster, stars are very close to each other and are tightly bound by Gravity.  All the stars revolve around the galactic core. But Omega Centauri is considered to be the most massive cluster ever. It is estimated to have more than 10 million stars in it. This cluster is so large that its diameter is about 150 light years. It is also known as NGC 5139 or Cald well 80 . This is the largest massive cluster ever discovered in the Milky Way galaxy. This cluster can be easily seen from the earth with the naked eyes.  All the stars in it are...

1. Today we are well aware those Black holes are the objects that have a greater gravity than any other object in the universe. But do you know why they are known by the word “ Black hole ”? Of course, black holes were predicted a hundred years ago. But the word black hole was first used by the American astronomers John Wheeler In 1967 . 2. The temperature of the accretion disc outside a blackhole can reach millions of degree Celsius. But you may surprise to know that studies have shown that the central temperature of a supermassive black hole can be up to 1.4×10 -14 kelvin. This is an extremely freezing temperature. This temperature is very close to absolute zero but not equal to absolute zero. In fact the absolute zero temperature is -273 0 15 Celsius. At this temperature, the movement of atoms stops completely. If we talk about the coldest place, it is NASA’s Cold Atom Laboratory with a temperature of -273 degree Celsius. This is also exactly one degree less than absolute ze...

  The winners of the 2020 Nobel Prize have been announced. But sadly, Stephen William Hawking, a scientist and cosmologist, is no longer with us. We will always miss him. The Nobel Prize will be awarded to three scientists Roger Penrose, Peinhard Genzel and Andrea Ghez. This time the Nobel Prize is given for explaining the theoretically and mathematically to black hole and finding the supermassive black hole in the centre of the Milky Way galaxy. This is very big achievement in the field of astrophysics. Hopefully in the future we will continue to receive information on the discoveries made by these scientists. The Nobel Prize will be awarded to scientists on December 10, 2020. Now we try to understand the black holes. Black holes is something we now a lot about, but not everything. Today we have information about black holes, theories, artistic illustrations, computer simulations and most important a picture of it.   Scientists work day and night to understand black holes ...

  A s we know the Big bang happened 13 billion years ago. Because of Big bang everything came into existence that we know everything and all that remains to be known .The scientists has different theories on whether the big bang happened or not, but now it has been completed proven that there was a big bang .But some scientists believe that their entire universe is moving inside a black hole .There is a reason for them to believe so, which may be true. Because we still don’t know what exactly happens inside a black hole .Or whatever goes inside the black hole, where does it end up. But we know how black hole is formed .scientists believe that their entire universe could be inside one black hole , Because there are many similarities between the big   bang and a black hole . Just like when the big bang happened, the whole universe was contained in one small Atom. Which is also called singularity .Similarly, when a star becomes a black hole, it also collapses in its own grav...
