K2-141b Discovered: A Hellish Exoplanet
K2-141b: a hellish planet! Before we found the first exoplanets — planets orbiting other stars — it seemed reasonable to suppose that other planetary systems looked like ours: small, rocky planets close to a Sun-like star, a big Jupiter and a few other gas giants farther out. But after a quarter-century of discovery revealing thousands of exoplanets in our galaxy, things look very different. In a word, we (our solar system) are “weird” — at least among the planetary systems found so far. Just how weird is still a matter of debate. And weirdness is relative. In fact, we found: Planets made of water, planets with a diamond core; Planets too hot, planets too cold; Planets that shouldn't exist; Earth-like planets. ------------------------------------------------------------------------------------------- Subscribe for more videos:https://www.youtube.com/c/InsaneCuriosity?sub_confirmation=1?

This appears to be a new challenge for astronomers, like the one they had when they first started studying the different type of stars. The problem's that it will take time to have some good theories of planetary formations because planets are way more numerous than stars: astronomers estimate that every star in our galaxy has (almost) a planet orbiting around it.  This means that they are literally everywhere in the universe! They are thousand of billions! Can you imagine such a huge number? We found even many planetary systems, like our solar system, in which some planets orbit a star similar to our Sun.  Today we want to talk about one of the most bizarre planets we discovered: K2-141b. This is a planet where it rains rock. We know what you are thinking: how is it possible it rains rock? Well, later in the video you will have the answer to this question.  Ladies and Gentlemen, fasten your seatbelt and follow us on this journey through the universe: we will bring you far away, around the K2-141 star, to introduce to you the planet K2-141b. Are you ready? Many ancient philosophers, as Epicuro and Democrito, guessed that other worlds might exist, basing their thoughts on a philosophical point of view rather than physical demonstrations. Much later, in the sixteenth century, the Italian philosopher Giordano Bruno was the first to assert that:  “There are therefore countless suns and an infinite number of worlds orbiting around them, like the seven worlds orbiting our Sun”.  (Giordano Bruno, On the Infinite Universe and Worlds, 1584) About 2300 years after Epicuro's ideas, and 400 years after Giordano Bruno, scientists Michel Mayor and Didier Queloz found the first extra-solar planet: 51 Pegasi b. For this discovery, they were awarded The Nobel Prize in Physics in 2019. Since then, the hunt for extra-solar planets started, and astronomers all around the world became planet hunters. Although we have still a long way to go before we get a well-built statistic for exoplanets, we can study each of them, understanding how different they are. Until now, there are 4301 confirmed exoplanets and 3192 planetary systems. One of them is K2-141b, the hellish planet.  In these images, you can see that, if there's something that resembles hell, this is certainly the case of K2-141b. On his surface, the temperature reaches extreme peaks, and everything is somehow reddish.  But...who found it? And how did he reach hell?  It was detected in 2018 by Luca Malavolta, from the Physics and Astronomy department of the University of Padua, using the so-called “transit method”. This method was our...highway to hell! The transit method measures the light curve of distant stars for periodic dips in brightness, that are the result of exoplanets passing in front of the star relative to the observer. How's K2-141b orbit? ------------------------------------------------------------------------------------------- "If You happen to see any content that is yours, and we didn't give credit in the right manner please let us know at Lorenzovareseaziendale@gmail.com and we will correct it immediately" "Some of our visual content is under an Attribution-ShareAlike license.
