  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.

1. Our time is determined by the rotation of the earth. The earth completes one Revolution around it in about 24 hours. This means that it has 84,400 seconds in 24 hours.  But recently scientists have suggested that the Earth’s speed is slightly faster than normal. Because of this our day is ending a little early. Scientists now have such accurate clocks that they can detect a difference of a thousandth of a second. It is now assumed that the earth has been rotating a bit faster on its axis in the last 50 years and has decreased by 0.05 milliseconds in an average day. Of course, it doesn't seem like much. In addition, July 19,  2020 saw a decrease of 1.44602 millisecond in 24 hours in the day. 2. According to scientists, the maximum temperature in this universe can be 1.42×10 32 Celsius. That's 142 nonillion degrees Celsius. This means that this higher temperature can never be achieved. This is also called Planck temperature. There can be no higher temperature in this univer...

1. The Largest Cosmic Void Do you know about the largest cosmic void in the universe? At the moment it is KBC void. Cosmic voids are places that are completely empty or have a very few galaxies. There is only darkness in them which can extend to millions of light years. Scientists say they may have been formed shortly after the big bang. It is generally believed that matter spread evenly in all directions after the Big Bang. But that probably didn’t happen. It accumulated in large numbers in many places, and only a small amount in other places. Or not at all. Scientists attribute this to baryon acoustic oscillation (BAO). Which may be caused in considerable fluctuation in the density of matter and its speed?     These vibrations can change the state of the matter. Due to which matter did not accumulate much in some places. In addition, dark energy later expanded these cosmic words to many more. The KBC void is the largest cosmic void ever discovered. It was a discovered...

Billions of stars and their planets and even their moons orbit the centre of a galaxy. There are many types of galaxies. There are more galaxies in the entire Universe than there are stars in the Milky Way galaxy. Today we will talk about that seems to be somewhat different from all the galaxies we have discovered so far. The name is Dragon Fly 44 Galaxy which is about 300 million light years away from us. The Scientist has a very strange opinion about this galaxy discovered just a few years ago. Astronomers say the galaxy is made up about 99.99% dark matter .   Image source-google | Image by- ESA/Hubble&NASA,D.Calzetti  https://spacetelescope.org/images/potw1936a/ Dark matter is a very important part of this Universe but scientists have not yet been able to see or detect it. We know about this missing substance because of the effect of its Gravity. Which retain the shape of Galaxy. Due to which the stars do not scatter out of the galaxies. Just like glue. Of course ...
