Nature and Cultivation: Strange Cases of Exoplanet Cousins

 Returning to the long-standing debate between scientists, they try to find out whether human behavior is determined by the environment or just the result of human genes. Planets and people can have a lot in common, and the atmosphere of the two from

 "Cousins," because the two distant, gaseous and burning worlds are naturally the same in size and temperature, rotating around their almost identical parent star at the same distance, astronomers believe their atmosphere is similar. . They found that they were surprised - one of the similar worlds is more haze than the other, and the difference between these different worlds is now a pleasant mystery, waiting for the curious planet scientists to solve, they are trying to understand why these two There is such a difference. A closely related world.

 "What we see when we look at the two atmospheres is that they are not the same. - WASP-67b is more haze than the other - HAT-P-38b. We can't see us and #39; expect, we need to understand why We found this difference."

 Observe the two "cousin" exoplanets & spectral fingerprints and measure chemical composition. "The effect of clouds on the spectral characteristics of water allows us to measure the amount of cloud in the atmosphere," Bruno added.

"This tells us that there must have been something that changed the look of these planets in the past," he continued.

From a historical perspective, finding a distant alien world, located in the family of stars outside our sun, proved to be a difficult endeavor. Found the first from

 A generation has clearly represented one of the greatest achievements of mankind. Discovering a giant planet, such as the banded giant Jupiter in our own solar system, has been compared to mosquitoes that observe light and jump off the 1000-watt bulb in the streetlight - the observer was 10 miles from the hotel.

 The harder it is to find out. For example, if an alien astronomer associated with a technologically advanced civilization continues to search for other planets in our remote parts of the Milky Way, it will be difficult to find our asteroids. This is because our planet seems to be just a mistake and a negligible spot in the vast space. In fact, our planet is very hidden and will not be opened by alien astronomers because the glare of our stars overwhelm it.

The first detection of an exoplanet occurred in 1988. However, the first confirmed discovery occurred in 1992, when some strange and hostile planets were detected hovering over a dense, city-sized stellar body called from

 In the terrible violent explosion of supernova, the remains of large-scale stars have disappeared. This anger, fatality, and the final glory of the flame mark the violent and disastrous end of the star.

In 1995, astronomers discovered the first exoplanet in orbit around a still "living" star, just like our own sun. However, this historic discovery left confusion in its wake. The newly discovered alien world is called from

 Most astronomers believe that giant gas planets can only be farther away from their stars - comparable to Jupiter's distance from the Sun. Jupiter is located in the cold outer periphery of our solar system.

 The method looks for tiny oscillations caused by orbiting planets on the stars - the larger the planet, the larger the swing, the easier it is for planet hunting astronomers to discover.

As of June 1, 2017, 3,610 exoplanets have been discovered, including 2,704 planetary systems, and more than 610 planetary systems have been validated. Since 2004 from

 Thousands of candidate planets have also been discovered, of which only about 11% may prove to be false positives. Planetary hunting astronomers estimate that about one-fifth of the stars similar to our Sun are circumvented by a planet of "earth size" on Earth. from

Some exoplanets clung to their parent stars in such tight sweeping orbits, and they only need a few hours to complete an orbit. However, there are other alien planets that take thousands of years to circle their stars. In fact, some exoplanets are too far away from their parent stars, and it is sometimes difficult for astronomers to determine if they are really bound by gravity. Almost all of the exoplanets discovered so far have been residents of our Milky Way, but some interesting but still unproven extragalactic exoplanets have been discovered.

 : The strange case of the exoplanet "Cousin"

Two mismatched "cousin" exoplanets - a cloudy day and a clear circle - a yellow dwarf that surrounds them every 4.5 Earth days. Both exoplanets hug their mother stars, closer than Mercury hugs our sun. However, long ago, these planets were likely to migrate inward from the farther areas where they were born to the flames and burning of the open fire parents.

Due to different situations, one planet may be different from another. "Now they seem to have the same physical properties. Therefore, if their measured components are defined by their current state, then it should be the same for both planets. Instead, it seems that their formation history may An important role," research co-researcher Dr. Kevin Stevenson explained on June 5, 2017 from
