The Strangest Star In The Universe


has seen a falling star, also known as a shooting star. I confess, I sincerely believed such was the case that these were, in fact, stars – much like I believed in Santa Claus. But then I heard the shocking truth: these are not, in fact, stars. When peering into the sparkling emptiness of the night sky, I watched as another meteoric body, for the umpteen-billionth time, tried to ram through the earth’s atmosphere. This happens constantly, day in and day out. Millions of cosmic bodies hurl themselves towards the surface of our planet every day. Really, there is nothing very special going on here. So, despite the apparent absurdity of the phrase: It turns out that real falling stars do exist in our universe. Fasten your seatbelts, ladies and gentlemen. Once again, we set off into deep space. Meet Mira, or as it is also called, Omacron Ceti. A sizeable star, it is 700 times larger than the diameter of our sun. It is an even stranger and more surprising star than Betelgeuse, the heroine from our last installment. The first mention of this beauty is found in Hipparchus in 134 B.C., as well as in the testimonies of Chinese astronomers later in the year 1070. But its almost supernatural properties were discovered only recently. Pastor/astronomer David Fabricius quite by chance, and without realizing it, discovered a new type of star on the morning of August 13, 1596. At that time, he was just watching Mercury. Or rather, he was going to measure the angular distance from the planet to the star glittering nearby at an apparent magnitude of 3 in the constellation of Saetus. Interestingly, he had never come across it before, and it was also notably absent from all the stellar maps and globes. Though, of course, maps and globes were not as accurate in ye olden days, and the disregard for some not very bright star was commonplace. Fabricius began to keep an eye on the stranger, and lo and behold, its brilliance grew right up to a magnitude of 2. And it became the brightest star in its constellation by the end of that August. But then in September, the star faded. And by mid-October, it had disappeared completely. In full confidence that this was a different, new star, Fabricius stopped observing. But to his great surprise, he came across this great mysterious travelor 13 years later on February 15th, 1609. But, to be fair, astronomer Johann Bayer managed to notice it about 6 years before this in 1603. He entered the data into his famous star atlas but had not yet suspected the super properties of his find. By the way, by that time, the star had already reached a stellar magnitude of 4. Various astronomers from around the world began to closely moniter Omicron Seti for the next several decades. So, for example, the Polish astronomer Jan Hevelius who observed the stellar body from 1659-1682, called it Mira, which is from Latin, and translates as “amazing.” And he was absolutely right. This star is amazing. Usually it is so dim that it is quite difficult to see with even a small, amateur telescope. But due to its peculiarity, it becomes the brightest star in the constellation Saetus at certain times. The so-called “peaks.” Then it fades again and becomes almost invisible. And then again, and again, and again everything repeats. Scientists finally, by the middle of the 17th century, established that this miracle represented a new type of variable star, with a very long period of brightness and a very large amplitude. To put it simply, Mira is a star that constantly changes its brightness, but it happens with a fair bit of irregularity. The glitter of a star, for those who do not know, is its apparent stellar magnitude. The same as luminosity or even simpler, brightness. Using the astronomical scale, smaller numbers are brighter. The brightness of Mira increases three and a half times in just 332 days. From a brightness of magnitude 10, when it is almost invisible in a telescope, up to a magnitude of 2, when it becomes the brightest in its constellation. As I said, there is no pattern to her behavior. As a matter of fact, the period and range of brightness changes and is completely unstable. One time Omicron Seti went from the relatively dark 9th magnitude and then increased to the 5th, and then back again. Another time, she faded to the 10th magnitude, but then shot up to her maximum brightest magnitude of 2. As you can see, the fluctuations in luminosity are simply immense. But what does all this mean? The luminosity of Omicron Seti, aka Mira, at the minimum of its brightness almost corresponds, or is even slightly less than, the luminosity of our sun. That means then, that at the maximum, the brightness of Mira will surpass that of our sun by 700 times, and sometimes by as much as 1,500 times the brightness of our sun. The whole point of this is this: when red giants pulsate, the temperature of their surface also changes, which immediately affects the optical properties of the stellar atmosphere. As the temperature rises, the chemical compounds decompose, and the atmosphere becomes more transparent. Also, a considerable role is taken by hot hydrogen masses, which erupt into the atmosphere during the periods of maximum brightness and further increase the brightness of the star. At least, this is the most plausible explanation which I have managed to unearth of the amazing changes that regularly occur with Mira Seti. And still there is something more. Scientists noticed in 1919 that a second spectrum was superimposed over the Mira spectrum. And it belongs to a very, very hot white star. A satellite was discovered very close to Mira 4 years later. This hot little star is a white dwarf called Mira B. which, by the way, literally feeds on its much larger neighbor. Little Mira B orbits the giant Mira A only once every 400 years. And therefore, the satellite has made just one complete revolution around Mira A since the time of Fabricius. The average distance from the main star to the orbit of the white dwarf is about 70 astronomical units. That is to say, 70 times the average distance from the earth to the sun. And the most interesting thing is that this little dwarf star has similar properties to her much more voluptuous friend. The white dwarf also changes its brightness regularly. But this happens for several other reasons. Mira B has an accretion disk through which the white dwarf interacts with the main star, sucking away stellar matter from her much larger sister. Because of the unevenness of the supply of this substance, the luminosity of the satellite also changes. On average, the brightness value of the dwarf ranges from magnitude 12 to 9.5. It should be noted that the measurement of changes in brightness in stars of this type is a monumental amount of astronomical work. Just imagine in order to obtain the amplitude of oscillations of the luminosity of a star for a period of 13 years, scientists need to take into account and superimpose all the fluctuations in the brightness of the star during this period. And their duration, by the way, is measured in minutes. And finally we come to our last couple of delicious tidbits. The Galaxy Evolution Explorer Satellite, also known as the Galex, is an orbiting ultraviolet space telescope launched in 2003. The Galex discovered a tail of matter stripped from the outer sphere of Mira A, like that from a comet. A gigantic tail of material, the length of which is about 13 light years. So that you understand how long this really is, the distance from our sun to the closest star is about 4 light years. That’s a mighty long tail. Most of the stars in our galaxy slowly rotate around its center, moving about the same speed and in the same direction as the interstellar gas. In contrast to this, Mira is shooting through the galactic gas cloud at a speed of 130 kilometers a second. As a result, the matter thrown out by Mira is simply blown back, forming a bow wave tail of compressed gas. As calculations show, every 10 years, the star drops a mass equivalent to that of the entire earth. To form such a tail, the star has taken at least 30,000 years. Oh, how I would like to see something like this up close. It is a pity that I would need to be a god to make it happen. A gigantic swelling located in front of this star is clearly visible in these pictures from the Galex telescope. This is the region of the shock wave. Something like this is formed in front of a boat’s nose when cutting through water at high speed. Or, for example, in front of a bullet moving at supersonic speed. This is matter thrown out by the star experiencing a head on collision with particles of interstellar gas. And here my story comes to an end for today. In conclusion, I should like to add that currently, we have discovered more than 46,000 such variable stars in the Milky Way, and about 10,000 in other galaxies. And this is only the beginning as more are being discovered every year. Put likes or dislikes if you don’t like it. Subscribe to the channel. Share with friends and well behaved acquaintances.

  2. I was born in streator Illinois where clyde tombaugh was born and that's why Pluto will always be a planet to me suck it Neil lol no seriously I think you are one of if not the greatest man to do astrology keep up the great work and Oh Yeah this video is kick ass

  3. I suspect this could be similar to the star that I saw few weeks ago. I was peeing at the backyard and was staring the night sky due to the magnificent numbers of bright stars. that placed is far from the city and located near the peak of the mountain . as I stare at the night sky I saw a bright steady object that turned more brighter then slowly fading and my eye could no longer see it. after few days it appeared again like before it turned brighter then slowly fading.
    I was left in amazement in pondering what it was.

  6. Who ever said how did i fond this channel when you was trying to sleep why not try clicking off YouTube and shutting your eye as for the guy who is talking you should have been well asleep ive had loads of sleep and I drifted of not because its boring but because his voice is soothing ha

  7. First off shooting stars are stars! Here's why, the stuff it's made from were made by stars so yeah they are indeed stars. Next st Nick was real he's just dead so yeah not one but 2 bombshell moments this thing is wrong on in under one minute

  8. They donโ€™t know this but itโ€™s actually aliens with special machines they have invented that they steal energy from stars to power their ovnis.

  9. 4:40 Wouldn't a star with a brightness of mag 2 be… just under 1600 times brighter than one with mag 10?

  10. Narrator: I always though shooting stars were actually stars like I thought Santa clause was real

  12. Is it possible for nasa to put a motion camera on those satellites so we can see this stuff in motion???

  13. This is awesome. I often wonder why the vastness of the universe; to what purpose is this? How do we relate our scientific knowledge of the universe to religeon and spirituality?.

  14. I believe the brightness is just increased consciousness using that star as a conduit/portal.
    You may say all falling stars , are stars. It is a physical form of consciousness , which is invisible light , and visible light but also dark matter.
    When we evolve as a race of beings we become concsiousnees , which are also suns and stars.
    When we die , we become consciousness as well.

  15. The awkward moment when I have a friend called TaMIRA ๐Ÿ˜‰ love ur voice and information bro xxxx

  16. I thought he said โ€œshut upโ€ in 5:16……. watching this at 4am using my earphones and I was shookethhh bahahahah Iโ€™m alr wheezing the first part cos my middle name is mira lol

  17. Don't you really see a star trying to save an other dying one ? Like really ?

  18. Those are stars from heaven they will fall on earth Revelation 6:13 (KJV) And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.

  19. It was David Bowie ……โญ๏ธ๐ŸŒŸ๐Ÿ’ซโœจ๐ŸŒŸโญ๏ธ๐Ÿ’ซโญ๏ธโ˜„๏ธ๐Ÿ’ฅโ˜€๏ธ

  20. If you close your eyes and listen to this video, youโ€™ll almost think youโ€™re listening to an episode of The Wonder Years.

  21. Couldn't this possibly be explained by a chain of planets stringing one after another from biggest to smallest that would make this "constantly brigher" star look as if it looses magnitude in brightness over the course of time and that there is simply so many planets or orbs that there is no real break in light?

  22. What if there is another life form that put a type of lens over their star to try to signal that they are there. It will change the star brightness in a very artificial way and we just aren't getting the message. :O

  23. Mira A is a pretty big star. What if there's a second dwarf orbiting inside the photosphere? It would suck in hydrogen until a secondary fusion event occurred (once the dwarf collected enough new matter). The output of the binary would vary wildly…

  24. Since they haven't seen any where near every star in the universe they can only know this star is strange(different). They don't have information enough to place it is any sort of order, never mind designating it Number one strangest star.

  25. I have seen anchiant remains of others aliens are not allways what you perceive them to b.they can be i inch tall ever think of that. their civialazation remains can be in the water around you or the trees in the deserts.the world was much different many years ago remains could have been left on rocks as big as a pebble. So keep an eye on the rocks you kick sometimes.they might have been a message in a bottle of sort.good luck hunters

  26. IT MIGHT BE SOMEWHAT OF AN OVEREXAGERATION TO DESCRIBE THIS STAR AS THE STRANGEST IN THE UNIVERSE SINCE OVIOUSLY OUR TELESCOPES HAVE NOT REVEALED ALL THE BILLIONS OF STARS IN THE BILLIONS OF GALAXIES IN THE UNIVERSE ! A MORE
    APPROPRIATE HEADING WOULD BE…STRANGEST STAR SO FAR OBSERVED !
