INSIDE SCIENCE

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...

Every day new discoveries and objects discovered in space. One of these is the Nebula. Nebulas are a very special part of creation. Today we are on this Earth only because of the Nebula. Our star, the earth and whatever is part of our solar system would once have been in the nebula only in the form of gas and dust. All the stars and planets are formed in the nebula. By the way, the nebulas itself look like a different and beautiful. Because the irregular expanding gas in it gives it a beautiful shape. It can be of many types. Like Emission nebula, they are the most colourful because they contain ionized gases. Due to this they emit light of different wavelengths. There are other similar nebulae, such as Planetary Nebula, the reflection nebula, the dark nebula and supernova Remnants. The Hubble Space Telescope was launched on April, 24 1990 and has performed millions of observations in interstellar space and is doing. It doesn’t know how much beautiful nebula it has captured. Whos...

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...
