Fog has been found in the form of a distant planet that is more than twice the size of Earth. It was the smallest of the world, though he met the water in his atmosphere all around, and it may rain and there will be no water. Why should the world be a seductive candidate in search of survivors outside of our global existence.
Finding water around the exoplanet (a world outside of our Solar System) is very popular with scientists because water is the key to the survival of our planet. The same is true for biology in other parts of the world. Researchers have found this ideal ecosystem alongside exoplanets in the past, but these worlds have not been ideal for biodiversity to flourish. These are large air balloons, about the size of a Jupiter or Neptune, with no biological surface that we know they do not have.
This planet, in detail in the study submitted * to Astronomical film will be published in arXiv last night, it was a little more unique. Named K2-18b, it is nine times larger than our Earth, a kind of planet, called the small Neptune. Worlds of this size are in our Galaxy, but they are at fault with our own System system. K2-18b also revolves around a sweet spot next to its star known as the habitat zone, which is just right for the pool water on the surface of the planet. Of course this planet shares some very important features with our planet. “For the first time a planet in this warming system – a very similar system to Earth – we show that it is not pure water,” said Björn Benneke, a researcher at the University of Montreal and director of the study was published in ArXiv, square The label.
While finding water is a big problem for exoplanet researchers, this world may not be full of oceans. After all, it looks like the planet’s surface may not be flat, due to its size. “These planets do not see anything like the Earth,” said Sara Seager, an MIT expert and professor, who did not participate in the study. The label. “We will never fight because we know we have a war world.” K2-18b also has a circle on a star beyond your Sun. First, these factors significantly reduce the likelihood that the organism will survive.
Researchers first discovered NASA’s K2-18b, a NASA Kepler Space Telescope, a spacecraft about 100 million miles from Earth that has been chasing exoplanets for the past decade or so. Every time the exoplanet goes directly between its main star and the Earth, the brightness of the star is reduced, this is a small difference that Kepler sees. By observing these exchanges, Kepler discovered more than 2000 exoplanets. In 2015, the mortgage rate held at K2-18b, just 111 months-a-month.
So, in 2016 and 2017, Benneke and his team used NASA’s Hubble Space Telescope, now around the Earth, to learn more about K2-18b from environment. The chemicals and molecules that surround the exoplanet can tell us a lot about things that are hidden from the surface of the distant universe. For example, the abundance of machinery in Earth’s atmosphere is a by-product of the many biological organisms that live here.
Studying the atmosphere of the exoplanet is difficult in worlds the size of Earth. The light from these rocks on the rocks of the sky is just as bright as the light coming from their main stars, which is hard to see. In order to understand what is on the exoplanet in the atmosphere, researchers need to look at the starlight as it analyzes the “ends” of the universe. When light travels through pressure, it is simply different, indicating the types of atoms that are present. This is very simple with measurement challenges to meet.
Researchers are lucky enough to have K2-18b because it has a feature that extends far, making it easier to observe. “It looks like a hybrid planet that may have freezing temperatures, but most of it is dusty,” Benneke says. Also, it is surrounded by a kind of weak star, known as a red dwarf, which is not as bright as a star like our Sun. It makes it easier to study the planets that may be moving around.
Benneke and his team saw the planet as it traveled eight times, so they could see the mist of water in the sky. They made some examples of the atmosphere, and found that the fog was in the cloud, where the water evaporated and rained on the planet – just like the Earth. ‘If you talk to a biologist, they don’t pay attention to steam; Water is important to them, ”says Benneke. “Because biology just works when you have water.”
Again, there is a lot we do not know about this planet, especially the part of its surface. According to Seager, extrasolar planets called planets such as Earth, Venus, or Mars are less than 1.6 times the size of our planet. This is 2.3 times larger than the Earth, which means the stone is unlikely to hit. “It’s just above that threshold,” Seager says. A large rock is surrounded by a large envelope of air, perhaps leaving half of it to be ice water. The option is not very helpful to have a sea urchin on rocky lands, as here in the World. “These objects, mini-Neptunes, are very common, and we don’t know what they are,” Seager says.
So, while the findings are good these days, the search is still the whole great treasure: a rocky exoplanet with water in its atmosphere. When that happens, it will be a great day for the exoplanet community, which brings out the calming side of the Earth we have seen.
The next task is to learn about the characteristics of K2-18b and the religions that live on the planet Earth. Scientists can take this information and more and more mobile phones from the internet will become more popular in the coming years. In particular, NASA’s upcoming James Webb Space Telescope, which will be a major observatory after its launch in 2021, could be a reference to the K2-18b spacecraft. Telescopes can study less-than-K2-18b worlds and things similar to our world, in addition to mini-Neptunes and worlds orbits in the constellations of their stars .
“This is the first way to look at the planets to the right of the orbit around other stars to see what activities are there,” Benneke says. At this point, we know that everything that happens there will dry up, but it may not be completely alive.
