Apparently, the Hubble telescope still does not plan to retire and replace it with a smaller and more high-performance Webb. The data collected in 2018 and 2019 on this exoplanet “Jovian” were very valuable to scientists, who in the study published yesterday in the journal Nature Astronomy, were able to deduce in great detail the amazing atmosphere of this distant world. Made of titanium with drops of gemstones, flowing winds, and flights in unimaginable temperatures on our planet, WASP-121b contains everything only the most creative science fiction novelist could imagine, but it’s not a realm within our reach from firsthand exploration. 850 light years from us. To give an idea, a probe like New Horizons, the fastest one launched into space (80 thousand km / h thanks to the impact of the launcher) to enter its orbit and be able to directly observe it will take a little longer than at the moment, we must be satisfied with the data revealed by Hubble spectroscopy and the complex analyzes of scientists at the Massachusetts Institute of Technology (MIT), who present us with a completely ‘weird’ and wonderful world, even if there is certainly none. Wasp-121b is classified as a “hot Jupiter,” meaning it has properties and a diameter similar to that of Jupiter, although it’s actually just under twice the size. Another striking feature is that it orbits very close to its star, Wasp-121 clearly. The first result is that a year on this planet lasts only 30 hours, and the second is that this proximity makes it extremely hot; However, because it is obscured by tides, it does not rotate on itself and always turns into its star as it is facet (synchronous rotation), with very great thermal excursion between the bright side, between 2500-3000 degrees, and the dark side, with temperatures approximately half Low temperatures. Scientists have come to a whole range of conclusions about strange weather phenomena that must happen in this distant world at those temperatures and pressures, and although the presence of water vapor on an exoplanet was known from previous observations, the new study revealed patterns During which the water circulates between its sides day and night. And the oxygen atoms, which make up the water, disintegrate on the “light” side of the exop and due to the higher temperatures, the planet floats to its dark side, which is relatively cooler, where they unite again, forming a cycle carried by the winds blowing at speeds of up to 5 kilometers per second, Or about 18 thousand kilometers per hour. For scientists, the planet’s dark side is “cold” enough to host exotic clouds of iron and oxide, a component of gemstones like sapphire and sapphire. Scientists say these mineral clouds can also travel to the light side, where they are set to evaporate due to high temperatures, thus producing rain made of liquid gemstones.

It’s called WASP-121b and was discovered in 2015, but only today scientists get to know it better, thanks to data collected using the Hubble telescope’s spectrophotometers.

Apparently, the telescope Hubble He still has no intention of retiring and replacing him with a younger, higher performer web. The data collected in 2018 and 2019 on this exoplanet “Jovian” were invaluable to the scientists, who took part in the study published yesterday in natural astronomythey deduced in great detail the astonishing atmosphere of this distant world.

Iron clouds, titanium rain with drops of precious stones, flowing winds and unimaginable thermal journeys on our planet, WASP-121b It has everything only the most creative science fiction novelist could have imagined.

But it’s not a world within reach of direct exploration, it’s actually 850 light-years away. To give the idea of ​​a probe like new Horizonsthe fastest launch ever into space (80,000 km/h thanks to the launcher effect) to enter its orbit and be able to observe it directly would take just over 10 million years.

Wasp-121 B It is classified as a “hot Jupiter,” meaning that it has properties and a diameter similar to that of Jupiter, although it is actually just less than twice its size. Another striking feature is that it orbits very close to its star. wasp 121 clearly. The first result is that a year on this planet lasts only 30 hours, and the second is that this proximity makes it extremely hot.

However, because it is obscured by tides, it does not rotate on itself and always turns to its star with the same face (synchronous rotation), with a very large thermal excursion between the bright side, between 2500 and 3000 degrees, and the dark side, with temperatures about half as low. .

From spectroscopic observations, which identified streaks of water in the atmosphere of the planet, scientists came to a whole series of inferences about the strange atmospheric phenomena that must occur in that distant world at those temperatures and pressures.

Although the presence of water vapor on an exoplanet was known from previous observations, the new study reveals the patterns in which water rotates between its sides day and night.

Hydrogen and oxygen atoms, which make up water, disintegrate on the “light” side of an exoplanet, due to high temperatures, and then float to its dark side, which is relatively cooler, where they recombine, forming a cycle carried by the wind blowing at speeds up to 5 kilometers per second, or about 18,000 kilometers per hour.

According to scientists, the dark side of the planet is “cold” enough to host strange clouds of iron and corundum, a component of gemstones such as sapphire and sapphire. Scientists say these mineral clouds can also travel to the light side, where they are set to evaporate due to high temperatures, thus producing rain made of liquid gemstones.
