Most Strangest Planets In The Universe | Nature MRK
The cosmos is full of secrets and mysteries. The deeper we gaze into the abyss, the more questions arise that modern science cannot yet answer. Today we have the honor of meeting two very, very, very, strange Planets; although even calling them planets is a difficult proposition. Objects cfbdsir 2149-0403, or more casually known as cf 21. This is probably one of the most incomprehensible things in this known universe. I feel like this one's just for us, and at just the right time. at first this peculiar cosmic body was taken for a rogue planet meaning a planet which was somehow gravitationally ejected from its native system by other planets, or by some passing star. It was found a hundred light-years from Earth, discovered in 2012 by an international team of astronomers,
Led by one Philippe Delorme the first studies showed that its mass is 5 to 9 times the mass of Jupiter, But the planet is hot... and it's not supposed to be... but I'm getting ahead of myself. Let's do this in the proper order in general these orphan planets are a quite frequent phenomenon in the universe they are also sometimes placed in a group of objects known as Planum O's scientists believe that in fact there are quite a lot of them and some of them are much closer to the earth than this mysterious recluse
But they are extremely difficult to find because they often have zero luminosity so when Scientists found out that the possible rogue planet was hot the theory as to its being a planetary class body came into question To understand exactly what kind of game this is you need to turn to brown dwarfs for help Brown dwarfs are substellar objects that means smaller than a star Which don't have sufficient mass for a pressure and temperature in the core to trigger thermonuclear fusion of hydrogen to helium? like most stars in order to initiate a thermonuclear reaction based on hydrogen
Thanks to which almost all stars shine you need something with about 80 times the mass of Jupiter That's only about 8% of the mass of our Sun, but it's enough But only about 13 times the mass of Jupiter is enough to produce a thermonuclear reaction that confused lithium and deuterium so brown dwarfs are considered to be gas objects with a mass of between 13 and 82 Pater's think bigger than a planet smaller than a star if the mysterious object c21 weighs less than 13 Jupiter's .
Which it does as far as we can tell then it will most likely turn out to be a Jupiter like rogue planet .Thrown out of its nest and drifting unobtrusively not far from us galactically speaking .But wait it gets more interesting c21 glows in the infrared meaning it radiates heat into space a Young newly-formed planet is hot and glowing and it will glow until it cools and this cooling can last for millions of years According to the first observations after the discovery of this Mysterious object it seemed to be moving with a nearby group of stars called the a B - Radice moving group Scientists came to this conclusion because of its apparent proximity to this cluster And so surely our mysterious object must have flown from there all these stars indeed aratus
Group are very young appeared around the same time and are in relative proximity to each other in the past They could have influenced each other gravitationally Changing the orbits of the planets of neighboring stars giving rise to the appearance of our plan mo That is if c21 came out of a bead iratus, then it is probably a young planet Which hasn't cooled down yet however after more detailed observations with the help of Europe's Very Large Telescope in Chile the Canada France, Hawaii Telescope the Spitzer Space
Telescope and the use of the parallax effect which calculates more accurate distances to faraway Objects by taking measurements when the earth is in different places in its orbit around the Sun it turned out that c21 is about 130 light-years from Earth this is somewhat further than originally thought at First scientists assume that this little miracle object was about the same distance as the star system mentioned earlier about 75 light-years from Earth now far from all centers of star formation This possible planet can't possibly be young it must be over 500 million years old and if it is a plan amount it could be possibly exist there as Far as we know planets can only be formed in the orbit of stars add Fifty five light years away from a bead iratus, if it came from there flying for so long It would surely have had time to cool down
But this does not necessarily correspond with reality The temperature of the mysterious traveler is over 400 degrees And if it is almost two times farther than we thought that in fact it's even brighter, and if it is brighter that means it's heavier and according to refined calculations the mass of the object is between two and
Thirteen masses of Jupiter the upper limit just allows it to start the most undemanding thermonuclear reaction on lithium All the same most likely the mass is less at about seven Jupiter's what the heck is going on here additionally studies have revealed that it has a high content of heavy elements all the elements that are not hydrogen and helium and usually brown dwarfs have fewer such elements But the presence of these elements in this case is too little for a planet so we cannot say with absolute certainty That this is a planet But almost all the data leads to this conclusion more observations are the only way to get a better understanding of this strange object research will continue our
Understanding of the universe will grow and knowledge will increase at this time. We don't understand what it is but sooner or later mankind will receive an answer to this question Perhaps you my dear viewers Have your own opinion as to what this strange object is you can write all your assumptions in the comments?
I am looking forward to reading what you have to say in the meantime Let's move on to the next no less strange and still unexplained object Celt 11b is a giant plastic styrofoam planet. Yes, you heard that right It was discovered just recently and it's amazing properties were quite the surprise this giant exoplanet located 320 light-years from Earth is Incredibly bloated it's 40 percent larger than our Jupiter But has only about 1/5 its mass Such an impressive size and an extremely low mass make it similar in density to styrofoam in Reality, there's no foam in the composition of the planet it's just an analogy this unusual fluffy world has the third lowest density among all the Exoplanets that we have discovered of which we have managed to determine the exact mass and radius I hope it will shed light on how these mysterious objects are born and what happens to them next in their evolution in addition to the unusual density Celt 11b has distinguished itself for something else in a very short time it will
Disappear you see the exoplanet revolves around the super bright star Celt 11 which is in the process of? transitioning into a red giant This means that within the context of the thermonuclear Process the star has begun to burn hydrogen outside its core According to researchers the outer layers of the atmosphere of the Celt 11 star will expand over the next 100 million years and eventually the star will completely absorb the planet Celt 11 b and since our mysterious
Exoplanet performs one revolution around its parent star in just five terrestrial days this means that it is Extraordinarily close to the star and hence the absorption will happen quite soon astronomically speaking
But it's not all that bad due to the fact that Celt 11 is the brightest of the famous stars in our southern hemisphere Before its demise this strange foamy world will be able to tell us much about the composition of its atmosphere The transit method of searching for new exoplanets is one of the most popular among astronomers Due to the passage of a planet between its parent star and our telescopes the brightness of the observed star Decreases this indicates to scientists that an exoplanet can be in front of the star at that However the reduction in luminosity of the super-bright Celt 11 turned out to be so insignificant That this time astronomers could not immediately confirm the existence of the planet using the kilo degree extremely little telescope which consists of two robotic telescopes one in Arizona and the other in South Africa They work at the same time in unison as one hold telescope like giant binoculars the size of the earth astronomer Joshua pepper of the University of Pennsylvania
Said the discovery was very challenging the original Celt observations of the star it's light curve Showed only a hint of the transit a little under
0.3% change in brightness it was very difficult to obtain reliable complete confirmation observations Thankfully new observations confirmed the existence of the mysterious exoplanet Scientists are now trying in every possible way to figure out what the secret of Celt 11b is
Why is this planet so inflated so bloated and what generally causes such extreme density on other?
Exoplanets the researchers have also taken up further study of the star Hoping to better understand how such stellar bodies behave at the end of their life cycle and of course I'm already eagerly awaiting the results of these newest studies in the meantime I'll go make a couple more insanely interesting episodes just for you Thanks for your attention and see you soon, my dear friends if you have any ideas for future episodes Please leave them in the comments below the author of the best idea will have their name Presented in the video don't forget to put a thumbs up with my sincere gratitude
