INSIDE SCIENCE

 1. Cyril’s star which is located about 13,000 light years from the Galactic Halo is estimated by scientists to be 12.5 billion years old. 2. The star named WR 102 is having a surface temperature of about 210,000k which makes it the hottest star of the universe. 3. The Constellation Hydra is the largest of all 88 constellations. There are 17 major stars in the Constellation Hydra. 4. The first exoplanet to be discovered by scientists is called Gamma Cephei Ab, and it is located 45 light years away from us. 5. Hyades is the closest open star cluster to us and is about 153 light years away. 6. The first Quasar to be discovered was named 3C48, which was detected in 1960. 7. The nearest black hole to the sun is called Qv Tel Ab or HR 6819, which is part of a triple star system just 1,200 light years away. 8.  A star named MACS J1149 lensed star 1 existed at a very large distance of about 14,400 million light years from us. 9. 4U 1700-37 is a neutron star and i...

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...

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...

The stars are a very important part of this universe. No Universe can be imagined without them. It is because of their light that we are able to know this huge Cosmos. There is much type of stars. It depends on the elements inside them. Everyone must have heard about the Orion Constellation. This constellation has been important since ancient times. This constellation and the stars in it are quite popular.  In fact, it was associated with aliens.  Today we will talk about Rigel, One of these famous stars.  You can easily see this star without the aid of a telescope. Rigel is a very bright star. Its Apparent magnitude is +0.13 From Earth. This makes it the seventh brightest star in the night sky. Its Distance from Earth is about eight hundred and sixty light years. Rigel is a blue super giant and is quite a massive star. In fact, the brightest stars in the universe are the blue stars. They are much brighter and more massive than the sun. These stars consume the hydrogen...

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...

If one look at space, at first glance it looks very calm but looking at in another light, we see that it is also in turmoil. The Neil Gehrels Swift satellite was launched in 2004. The task of this Swift satellite released by NASA is to detect a Gamma ray burst , the most powerful and energetic event in the universe. Gamma ray burst EMIT as much energy in just 2 seconds as the sun emits throughout its lifetime.  All this energy came out in the form of a jet with the speed of light. This satellite has detected a lot of Gamma ray bursts so far. This could be due to the collision of two neutron star. Neutron stars are the core left over after a supernova in a star many times larger than the sun. The effect of gravity is so great that evens the protons of a remaining Core collapse on their own and turn into a neutron. It contains the strongest metal in the universe called nuclear pasta . A neutron star is made up almost entirely of neutrons. More than a hundred years ago, Einstein ...

We lived in a very small part of this huge Galaxy. Our Milky Way galaxy is made up of billions of stars. The Sun is the main star of our solar system. The sun is always the brightest star for us because it is the closest thing to the earth. The main star in the solar system is the main source of energy for the planets in that solar system. Each star that appears at the night has its own unique identity. Just knowing about them shows how special those stars are. Sometimes we search for the star in front of which our sun looks very small. Today we will get information about some such stars. These are the stars that try to tell us how bright or massive a star can be. Thousands of telescopes and space telescopes form earth showed us the reality of the universe that we still do not fully understand. Sometime telescopes find stars that how little we understood them. Let’s first know about one such amazing star. 1. Pistol Star     Image source-google | Image by- CenterForDetect...

 In 1960, Freeman Dyson, a British American Mathematical Physics and Astrophysics, mentioned a Dyson Sphere in a science paper, search for the artificial stellar source of infrared radiation. According to him, if there is an advanced Civilization in our Galaxy, how will we know about it?  So we can see them from their main star . There will have a spherical structure that is around their star .  All the energy from that star would be used by that civilization.  Freeman Dyson named it a Dyson sphere.  It will be a giant structure that will be built around that star. This will accumulate a large amount of energy of that star.  Image source-google | Image by- Kevin Gill In that case the star will in infrared. The need for energy on our planet is increasing day by day.  For which we're meeting the demand for energy from chemical fuels, electricity and today through nuclear fusion reactors. But all this energy resources are limited. This will surely end on...

We all know that Betelgeuse is one of the brightest stars in the constellation Orion . The Orion Constellation and its star have been important since ancient times. This constellation is considered special in Babylonians Egyptians Chinese and Hindu cultures . Every ancient Civilization has its own unique and interesting story about it. There are seven most major stars in this constellation. Which are Alnitak, Alnilam, Mintaka Rigel, Saiph, Bellatrix and Betelgeuse . For now, we’ll just talk about Betelgeuse.  Betelgeuse one of those stars is the subject of much discussion among astronomers. The reason behind this is that it loses almost half of its lustre. Scientists believe it will soon have a supernova explosion.   It is a giant red  star that is 642 two light years away from us. Betelgeuse is a 20 times more massive than our Sun and a thousand times larger. According to the astronomers this star maybe 8.5 million years. And it looks like the star is living ...
