Who wouldn’t know about geysers, everybody knows, most of us have seen geysers, usually when geysers are formed, when surface water is heated by magma, at an average depth of about 2,000 feet  The exposed rocks come in contact, and due to which under heavy pressure, this water boils, and because of this the mixture of steam and hot water comes running out towards the surface under severe pressure, and this  Like  The dish is manufactured. Did you tell us, there are geysers in the sun too, and these geysers are quite large, about these geysers of the sun has been mysterious for the last few decades, to find out the secret of these geysers, new research on spastic phenomena started  Are happening

As we know, the Sun is a burning fireball, in which the plasma is present, because of which it is burning, the lines of the Sun’s magnetic field move themselves in and out as ropes, due to which It releases a tremendous amount of energy. Sunspots, a typical solar event, are capable of hosting geysers or sites of frequent rejection activity.

Our solar system is the highest gravitational force of anyone, so is the Sun, which has a high intensity magnetic field in the atmosphere, there are two reasons behind it. The first reason is that hot plasma rises near the inner core of the sun, and it comes face to face with the numbness of the vacuum of outer space, once it cools, this plasma condenses, making the process  To start afresh, it gets ready and slips its way back.

The second reason is the rotation of the Sun, because as we know, the surface of the Sun is not as solid as the Earth, since the Sun is not a solid body like the Earth, different parts rotate at different speeds, and at the equator  Plasma rotates at the poles faster than the stuff. The magnetic field can be greatly enhanced by this combination due to the difference in sharp rotation, and it can be tied into a twisted rope of pure magnetic energy, as the stresses in these “ropes” are very high. The magnetic field lines begin to snap, and release that energy in the form of X-rays.

Those parts of the sun known as sunspots have particularly intense magnetic activity, and in these places are like tangled ropes of magnetic-field lines, the ropes themselves in the surface of the sun It takes The magnetic force of the Sun prevents the gas from reaching the surface first. Some of the sun’s sites that cool down to a thousand degrees, which we can see as dark colors on the surface of the sun.

Those parts of the Sun which are known as Sunspots, these Sunspots of the Sun are very chaotic, these Sunspots of the Sun push excessive magnetic field from inside to turbulent plasma. These phenomena of the Sun are so extreme, that some regions of the sunspot launch plasma jets far away from the Sun’s surface, a situation that requires a lot of energy and sufficient concentration of magnetic forces. The sunspot parts of the sun are so amazing, that the areas near them are capable of launching multiple jets in a regular pattern, similar to the way Old Faithful “geysers” in Yellowstone National Park in the US.

Orion, the constellation of the Universe, has a shining Betelgeuse red star, which has been faint for quite some time, the researchers say, that it has been happening for the past century, the phenomenon has excited astronomers a lot, will this star become a supernova ? And it will explode, this question is in everyone’s mind. Astronomers say that it would be thrilling for us to understand the behavior of Beteluse, astronomers had never seen it from Betelgeuse before, and many astronomers are not yet aware of the variable behavior of Supergirl stars like Betelgeuse, but astronomers There is a chance to learn more about the strange activity of the Betelgeuse star.

Betelgeuse is the brightest place, with Betelgeuse being one of the six or seven brightest stars in the sky at night, by mid-December, several places have fallen to 21st on that list. Betelgeuse is about 700 times larger than our sun, and the way it is bigger than our sun, so obviously, it will explode as a supernova one day, and we will be able to see this event at night, If mankind remains alive, it will give us a chance to watch an astronomical show.


Betelgeuse has been seen to glow and dim many times, Betelgeuse is a giant red star, a star late in its life, which has expanded to a gigantic size. Betelgeuse bubbles rise from the star’s surface to the top of the star, causing the mixture of warmer and cooler material on the star’s surface to sink back down, and such a change makes the Betelgeuse brighter over time. Richard Vasatonic, an astronomer at the University of Villanova, has measured the brightness of Bethelues with a 10-inch diameter telescope, at which time he noticed that Betelgeuse was faint again, December. In early 2019, he again realized, during the last 25 years that Betelgeuse had been fainted, Richard Wasatonic put a post on a site called The Astronomer Telegram, to alert other astronomers.

Astronomers have been surprised by the unusual dimming episode, because Betelgeuse is known as a supernova, and the question is whether Betelgeuse will explode, if Betelgeuse explodes, will it have an impact on Earth. According to the researchers, in order to harm the Earth, the Earth has to be extremely close to supernova radiation, but the Earth is about 724 light years away from the Betelgeuse supernova, which is out of danger, so the Earth will not be harmed  .


Astronomers have carefully observed the behavior of stars after a supernova explosion, but have not considered in detail how a star behaves when a star becomes a supernova. Astronomers don’t really know right now, whether the current dimming event is going to a supernova, or not, but there’s still a lot of potential for a bang, because there is so much uncertainty in Betelgeuse’s behavior and his age, though astronomers are Giving more accurate ideas, Betelgeuse will explode anytime in the next 100,000 years.

Our universe is full of secrets, and our scientists have been engaged day and night to learn these secrets. NASA has always been launching satellites, telescopes, to reveal the secrets of the Universe, and NASA has always been ahead of the Universe. NASA is now preparing for its next mission to uncover countless mysteries of the Universe, NASA will use new technology for these missions. NASA has selected proposals for its next four missions, aimed at studying cosmic explosions, as well as orbiting nearby stellar parts, how the planets affect the atmosphere.

NASA will select two proposals in 2021, after a detailed evaluation, as the next astrophysics mission under the Exploratory Program, and then selected missions to be launched in 2025. Thomas Zurbuchen, Associate Administrator at the agency’s Science Mission Directorate in Washington, says that these promising proposals under the Exploration Program reveal some of the most creative, innovative ways to help uncover the mysteries of the universe. To know the biggest cosmic mysteries of our solar system, I hope for the success of these small missions.

NASA has potentially selected two Astrophysics Small Explorer (SMEX) missions and two Mission of Opportunity (MO) proposals, potentially based on the science value and feasibility of development plans.  Each cost of the SMEX mission is $ 145 million, and each cost of MO is $ 75 million, excluding NASA’s launch cost.  NASA will give $ 2 million to each SMEX of the selected proposal to conduct a nine-month mission concept study.

There are many such places in the earth, whose images, when we see them, we are thrilled, and why not, it is so beautiful that we cannot express them in words, and it is so real, that  We want to go to these places. The world is such an image, which is not real, but still it is so beautiful, upon seeing it, it seems that the person in the picture is in real and he is now speaking, he was made by the artist  Is, that we are not able to differentiate between real and fake images. Friends, do you know, whatever image we see of the Universe is not completely real, I do not mean to say that the image of the Universe is completely fake, it is real, just like we are without any color  In the image, we fill the color according to ourselves, and after that it becomes so real, that we cannot tell that it is a fake image.

The telescope takes a photo of any galaxy or planet, it is not the same, as we see in the image, it is somewhat different, which is later expressed by the data.  The image taken by the telescope is like a white dot, if we see this, we will not understand anything, we will be able to see it as a point, so when an image is taken by the telescope,  First, the image is prepared by the computer according to the data, and after that we can understand the image properly.


 Whenever we see images of galaxies, stars, planets, and we have always seen that the universe is so good that everything is image, that as soon as we see them, we start analyzing them, as we all know. As we see the Universe image, it is not like that, but they are made in such a way that every common man can understand it, and analyze them properly. As we know, there is darkness in the Universe, we can see only those on whom Prakash reads, and cannot see those on whom Prakash does not read. We have seen the image of galaxies, that they are quite colorful, but in real time the galaxy does not look like that, when the telescope takes the image of a galaxy, it is like a white dot, and later on, the image of the telescope  With the help of, it is discarded, as if gas, dust is present in the galaxy, in that galaxy, then the gas presents the dust as red, white color, according to telescope data, This image is used.

In 2015, such a planet was discovered, its atmosphere is similar to our Earth, it is a planet that has a cloud like Earth, and researchers have indicated the presence of water in this planet. A planet was discovered in the constellation Leo 110 light years away from us, known as K2-18b, according to researchers the planet K2-18b is orbiting a star that is smaller than our Sun. This planet named K2-18b takes 33 days to orbit its star, its star light is active, which can prevent the radiation from exploding on the orbiting planet.

According to researchers, K2-18b is as far away from its Sun as it should be, as our Earth is at the same distance from the Sun, which should be distant, neither planet is warmer, nor colder in this distance. It happens, and this distance is right, which should be for the life of a planet.

To analyze the planet K2-18b, three teams were formed, which would study its atmosphere and its activity. In September 2019, two teams on the analysis of the planet K2-18b announced that we had indicated that there would be liquid water on the planet K2-18b, and it is likely that the planet would be habitable, but we would  It cannot be said that there can be life in this planet. Along with water for life in any planet, other conditions like temperature and pressure of that planet are also necessary for life. The third team report says that the pressure of liquid water on this planet can be good for developing life.

What astronomers have to say about the planet K2-18b, is that the planet K2-18b is a very unique target, which we recognized long ago. Björn Benneke , an astronomer at the University of Montreal, who led one of the teams that announced atmospheric analysis, in September 2019, about the planet K2–18b, which he published in the paper The Astrophysical Journal Letters.

Over the last three years, the K2-18b planet has been studied a lot of times, including Bennecke and his team of colleagues, with Benneke and his team using the Hubble and Spitzer Space Telescope data several times over the last three years. Motive K2-18b The atmosphere of the planet can be accurately observed. Researchers have previously studied exoplanet, and the exoplanet that has been studied so far is larger than the K2-18b planet, which is only 2.6 times the size of our Earth and 8.5 times its mass. The small size of the planet made the observations particularly challenging for researchers, as these planets require many detailed measurements that, combined, can provide a more in-depth investigation of the world.

Researchers say that lower-sized stars and smaller planets, such as K2-18b, make it easier to detect planets, because the observation of a planet depends on how, compared to Earth, that planet How much blocks the light coming from your star. If seen, a smaller planet blocks less light than a planet larger, but it has less light to block a smaller star, and because of which, it is seen as that small sign  It becomes easier to some extent.

Bennek and his team observed Hubble and Spitzer’s data by observing that no sign of water was found in the atmosphere of the exoplanet, and not any form of water. Its data has made us a lot more thrilled, says Beneck, because the data shows that there is a cloud deck on the planet. If there is no absence of water on a planet, then cloud decks can occur on that planet. To detect water in the planet’s atmosphere of K2-18b, Benecke and his colleagues used the model to determine that water had the right pressure and temperature to survive even at altitude.

Benneke says that as we know, clouds of liquid water are equally high on our earth, due to which rain occurs. Researchers say that the cloud of the planet K2-18b fills with water droplets, which makes it the most rain, the most strange is that there is rain on the planet K2-18b, but it is a lot of rain water It does not reach the ground, it will continue to fall until, due to temperature and pressure, it once again disappears. Benneke compared the rainfall on K2-18b to Terrestrialvirga, which occurs when rain evaporates before it hits the ground due to high temperatures and pressures.

For researchers, finding a similar weather pattern on an exoplanet is an intriguing possibility. In K2-18b, there are perfect conditions for the formation of clouds like Earth, but still this planet is not exactly like Earth. Researchers classify this planet as sub-Neptune, and the planet does not have a surface, it is a giant gas. NASA’s Kepler spacecraft determined that sub-Neptunes are the most common type of exoplanets in the Milky Way, making up more than three-quarters of the planet’s population.

Astronomers are having a difficult time understanding the planet of small gas, and this is why the findings of K2-18b are so exciting for researchers. For astronomers, understanding a planet like K2-18b can help improve a new experience and knowledge.
