The K2-18b planet exoplanet contains plenty of water clouds, but why this planet thrives astronomers.

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. Bj√∂rn 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.

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy.  And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light.  It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth.  Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower.  Today it is about 158 ​​million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon.  The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun.  During those periods, to operate the space shuttle, one should rely on…

SpaceX,Dragon Cargo Returns Mission in Pacific ends with SplashDown

SpaceX dragon cargo spaceship dropped at 5:48 pm in the Pacific Ocean.  The EDT (2:48 p.m. PDT) is located approximately 202 miles southwest of Long Beach, California, which is located at the end of the company's 17th contracted Cargo Resipulli mission for NASA.  Spacecraft returned more than 4,200 pounds for other valuable scientific uses. Some scientific investigations of Dragon's return to Earth include: Overview of protein crystals growth, in the use of NASA's biophysics-6, to be interested in cancer treatment and radiation safety  There has been an increase in the growth of two proteins.  Scientists are using ground-based predictions and X-ray crystallography in space to determine that proteins are beneficial in crystallization in microbiology, where some proteins can grow with big and small flaws.Microglio biosynthesis in M…
