Scientist found How Earth’s climate model helps describe the unimaginable life of the world, Thousands of computers on machine-size racks hit a deafening choir in an old brick building on the northwest edge of NASA’s Goddard Space Flight campus in Greenbelt, Maryland.
They issued 7 billion calculations per day and the second night. Together, these machines are known as NASA’s “Find” supercomputers and have the task of predicting future Earth climate using complex climate models.
But now they go further: Can any of the more than 4,000 strange strange planets outside our solar system that have been discovered in the last two decades survive? now the Earth’s climate model helps describe the unimaginable life of the world.
Scientists have found that under a number of surprising conditions compared to Earth, the answer is not only “yes” but also “yes”.
This disclosure has prompted many of them to answer questions that are very important for NASA’s search for extraterrestrial life. Is it possible that our ideas about what makes a planet worthy are too restrictive?
The generation of powerful telescopes and space observatories will certainly give us more clues.
With this tool, scientists can for the first time analyze the atmosphere of the most annoying planets out there: rocky planets like Earth, which can have an important element in life – liquid water – flowing on its surface.
It’s hard to explore the atmosphere that is far away at the moment. Sending a spaceship to the next planet outside our solar system or exoplanet will require 75,000 years with current technology. Even with a powerful telescope near the exoplanet, it is practically impossible to examine details.
The problem is that they are too small and immersed in the light of their stars so scientists cannot understand the faint beam of light – signatures that can reveal the chemistry of life on the surface.
In other words, part of the atmosphere around these ghostly planets, as many scientists emphasize, is like standing in Washington DC and trying to see the light next to a spotlight in Los Angeles.
“This fact makes the climate model important for this research,” said exoplanet scientist Carl Stapelfelt, who works at NASA’s Jet Propulsion Laboratory in Pasadena, California.
When searching for the cosmos with a large earth and space telescope, astronomers find a variety of world choices that seem to be produced from imagination.
For a long time, scientists have really focused on finding systems that are similar to the Sun and Earth. That’s all we know, “said Elisa Quintana, NASA astrophysics who led the discovery of the planet Kepler 186f in 2014.
But we realize that there are all crazy varieties on the planet. We found a planet as small as the moon. We found a giant planet. And we found several orbiting small stars, giant stars, and many stars.
In fact, most of the planets discovered by NASA’s Kepler space telescope and new transit satellites for extrasolar planets and earth observations are not in our solar system. They are between the size of the earth and Uranus gas, which is four times the size of the planet.
When a planet crosses directly between us and its star, we see that the star is a little dark because the planet is blocking some of the light. Measuring this decrease in starlight is a technique known as the “transit method” that scientists use to identify exoplanets.
The scientists made a story called the “light curve” which shows the brightness of stars in time.
This action allows scientists to see what percentage of starlight is blocking the planet and how long it takes the planet to cross the star disk. With this information, they can estimate the distance of a planet from its star and mass.
The planets that are the closest to Earth and the most likely living conditions so far have only been found around red dwarf stars that make up most of the stars in the galaxy.
This may be because red dwarfs are smaller and darker than the sun, making signals from orbiting planets more easily seen in telescopes. Because red dwarfs are small, the planets must move closer to the sun than Mercury in order to remain gravitational attached to them. And because red dwarfs are cooler than other stars, planets must be closer to them to absorb enough heat so that liquid water builds up on their surface.
Whether these planets can save lives is still a matter of debate.
Scientists show that red dwarfs can emit ultraviolet rays and X rays up to 500 times more dangerous on their planet than the sun in the solar system.
With this environment, this environment will eliminate the atmosphere, evaporate the ocean, and fry the DNA of a planet near the red dwarf.
