Astronomers discover a mysterious planet outside the solar system


Scientists discovered a mysterious exoplanet called “Hot Nippoton,” and researchers from the University of Kansas analyzed the planet, and they named it LTT 9779bIan Crossfield, who led the study, said: “This planet is exposed to radiation so intensely from its star that its temperature is more than 3000 degrees Fahrenheit and its atmosphere can completely evaporate. However, Spitzer’s observations show us its atmosphere through the infrared light that is emitted. From him the planet. ”

“This planet does not have a solid surface, and it is even hotter than Mercury in our solar system – it will not only melt into the atmosphere of this planet, but also platinum, chrome and stainless steel, a year on this planet is less than 24 hours – this planet does not have a solid surface,” Crossfield added. The speed at which it rotates around its star. It is a very extreme system. ”

The planet was discovered by a satellite TESS Last year, researchers used a technique to analyze the atmosphere, and Crossfield explained: “We measure the amount of infrared light emitted from the planet as it rotates 360 degrees on its axis, and the infrared light tells you what temperature something is and where the hottest and coolest parts of this planet are.” On Earth, it is not hot at noon; it is hotter two hours later in the afternoon, but on this planet, it is hotter at noon, and we see most of the infrared light coming from part of the planet when its star is straight at Higher and much lower than other parts of the planet. ”

The researchers hope the results will encourage further research into the atmospheres of exoplanets, and Crossfield emphasized: “I wouldn’t say we understand everything about this planet now, but we have measured enough to know that this will be something really fruitful for future study, and it has already been targeted. The observation is using the James Webb Space Telescope, which is the next large space telescope from NASA that will cost several billion dollars and that will ascend within two years. ”

He continued: “What our measurements show so far is what we call spectral absorption features – and its spectrum refers to carbon monoxide or carbon dioxide in the atmosphere, and we have begun to identify the molecules that make up its atmosphere, because we see this, and because of what a map looks like. Global temperature, it also tells us something about how winds circulate energy and materials around the atmosphere of this little gaseous planet. ”
