Nothing is discussed more during various award ceremonies than the outfits of the stars. Celebrities love to show off their splendor in front of photographers' lenses and attract the attention of the public. But sometimes their very original outfits cause outright bewilderment. See the weirdest celebrity outfits of 2015.

Today you will learn about the most unusual stars. It is estimated that there are about 100 billion galaxies in the Universe and about 100 billion stars in each galaxy. With so many stars, there are bound to be some strange ones among them. Many of the sparkling, burning balls of gas are quite similar to each other, but some stand out for their strange size, weight and behavior. Using modern telescopes, scientists continue to study these stars to better understand them and the Universe, but mysteries still remain. Curious to know about the most strange stars? Here are the 25 most unusual stars in the Universe.
25. UY Scuti
Considered a supergiant star, UY Scuti is so large that it could engulf our star, half of our neighboring planets, and virtually our entire solar system. Its radius is approximately 1700 times greater than radius Sun.
24. Star of Methuselah

The Star of Methuselah, also named HD 140283, truly lives up to its name. Some believe it is 16 billion years old, which is problematic because Big bang happened only 13.8 billion years ago. Astronomers have tried to use more advanced age determination methods to better date the star, but still believe it is at least 14 billion years old.
23. Torna-Zhitkova object
Photo: Wikipedia Commons.com
The existence of this object was originally proposed theoretically by Kip Thorne and Anna Zytkow; it consists of two stars, a neutron and a red supergiant, combined into one star. A potential candidate for this object has been named HV 2112.
22.R136a1

Although UY Scuti is the most big star, known to man, R136a1 is definitely one of the heaviest in the Universe. Its mass is 265 times greater than the mass of our Sun. What makes it strange is that we don't know exactly how it was formed. The main theory is that it was formed by the merger of several stars.
21.PSR B1257+12
Photo: en.wikipedia.org
Most of the exoplanets in PSR B1257+12's solar system are dead and bathed in deadly radiation from their old star. Amazing fact about their star is a zombie star or pulsar that has died but the core still remains. The radiation emanating from it makes this solar system a no man's land.
20.SAO 206462
Photo: flickr
Consisting of two spiral arms spanning 14 million miles across, SAO 206462 is certainly a strange and unique star in the universe. While some galaxies are known to have arms, stars typically do not. Scientists believe that this star is in the process of creating planets.
19. 2MASS J0523-1403
Photo: Wikipedia Commons.com
2MASS J0523-1403 may be the smallest known star in the Universe, and it lies just 40 light-years away. Because it is small in size and mass, scientists believe it may be 12 trillion years old.
18. Heavy metal subdwarfs
Photo: ommons.wikimedia.org
Recently, astronomers discovered a pair of stars with a large number lead in the atmosphere, which creates thick and heavy clouds around the star. They're called HE 2359-2844 and HE 1256-2738, and they're located 800 and 1000 light-years away respectively, but you could just call them heavy metal subdwarfs. Scientists are still not sure how they form.
17. RX J1856.5-3754
Photo: Wikipedia Commons.com
From the moment they are born, neutron stars begin to continuously lose energy and cool down. It is therefore unusual that a 100,000-year-old neutron star such as RX J1856.5-3754 could be so hot and show no signs of activity. Scientists believe interstellar material is held tightly gravitational field star, resulting in enough energy to heat the star.
16. KIC 8462852
Photo: Wikipedia Commons.com
The star system KIC 8462852 attracted close attention and interest from SETI and astronomers for its unusual behavior in lately. Sometimes it dims by 20 percent, which could mean something is orbiting around it. Of course, this led some to the conclusion that these were aliens, but another explanation is the debris of a comet that entered the same orbit with the star.
15. Vega
Photo: Wikipedia Commons.com
Vega is the fifth brightest star in the night sky, but that's not what makes it strange. High speed rotation of 960,600 km per hour gives it the shape of an egg, and not spherical, like our Sun. There are also temperature variations, with colder temperatures at the equator.
14. SGR 0418+5729
Photo: commons.wikimedia.org
A magnet located 6,500 light-years from Earth, SGR 0418+5729 has the strongest magnetic field in the Universe. The strange thing about it is that it does not correspond to the image of traditional magnetars with a surface magnetic field, like ordinary neutron stars.
13. Kepler-47
Photo: Wikipedia Commons.com
In the constellation Cygnus, 4,900 light-years from Earth, astronomers have discovered for the first time a pair of planets orbiting two stars. Known as the Kelper-47 system, the orbiting stars eclipse each other every 7.5 days. One star is roughly the size of our Sun, but only 84 percent as bright. The discovery proves that there may be more than one planet in the stressed orbit of a binary star system.
12. La Superba
Photo: commons.wikimedia.org
La Superba is another massive star located 800 light years away. It is about 3 times heavier than our Sun and the size of four astronomical units. It is so bright that it can be observed from Earth with the naked eye.
11. MY Camelopardalis
Photo: commons.wikimedia.org
MY Camelopardalis was thought to be a lone bright star, but it was later discovered that the two stars are so close that they practically touch each other. Two stars slowly join together to form one star. Nobody knows when they will completely merge.
10.PSR J1719-1438b
Photo: Wikipedia Commons.com
Technically, PSR J1719-1438b is not a star, but it once was. While it was still a star, its outer layers were sucked out by another star, turning it into a small planet. What's even more amazing about this former star is that it is now a giant diamond planet, five times the size of Earth.
9. OGLE TR-122b
Photo: Photo: commons.wikimedia.org
The average star usually makes the other planets look like pebbles, but OGLE TR-122b is about the same size as Jupiter. That's right, this is the smallest star in the Universe. Scientists believe it originated as a stellar dwarf several billion years ago, marking the first time a star the size of a planet has been discovered.
8. L1448 IRS3B
Photo: commons.wikimedia.org
Astronomers discovered the three-star system L1448 IRS3B as it began to form. Using the ALMA telescope in Chile, they observed two young stars orbiting a much older star. They believe that these two young stars were the result of nuclear reaction with gas rotating around the star.
Photo: Wikipedia Commons.com
Mira, also known as Omicron Ceti, is 420 light-years away and is quite strange due to its constantly fluctuating brightness. Scientists believe it dying star who is in the last years of her life. Even more amazingly, it moves through space at a speed of 130 km per second and has a tail that stretches several light years.
6. Fomalhaut-C
Photo: Wikipedia Commons.com
If you thought the two-star system was cool, then you might want to see the Fomalhaut-C. This is a three-star system just 25 light-years from Earth. While triple star systems are not entirely unique, this one is because the location of the stars far away rather than close to each other is an anomaly. The star Fomalhaut-C is particularly far away from A and B.
5. Swift J1644+57
Photo: Wikipedia Commons.com
The black hole's appetite is indiscriminate. In the case of Swift J1644+57, a dormant black hole woke up and devoured the star. Scientists made this discovery in 2011 using X-ray and radio waves. It took 3.9 billion light years for the light to reach Earth.
4.PSR J1841-0500
Photo: Wikipedia Commons.com
Known for their regular and constantly pulsating glow, they are rapidly rotating stars that rarely turn off. But PSR J1841-0500 surprised scientists by only doing this for 580 days. Scientists believe that studying this star will help them understand how pulsars work.
3.PSR J1748-2446
Photo: Wikipedia Commons.com
The strangest thing about PSR J1748-2446 is that it is the fastest spinning object in the Universe. It has a density 50 trillion times that of lead. To top it all off, its magnetic field is a trillion times stronger than that of our Sun. In short, this is an insanely overactive star.
2. SDSS J090745.0+024507
Photo: Wikipedia Commons.com
SDSS J090745.0+024507 is a ridiculously long name for a runaway star. With the help of a supermassive black hole, the star has been knocked out of its orbit and is moving fast enough to escape the Milky Way. Let's hope that none of these stars rush towards us.
1. Magnetar SGR 1806-20
Photo: Wikipedia Commons.com
Magnetar SGR 1806-20 is a terrifying force that exists in our Universe. Astronomers detected a bright flash 50,000 light-years away that was so powerful it bounced off the Moon and illuminated Earth's atmosphere for ten seconds. Solar flare called scientists questions about whether something like this could lead to the extinction of all life on Earth.
Actor Tom Hanks is a famous lover of antiquities. True, while other celebrities enthusiastically collect paintings, antique jewelry and other “trifles,” Hank prefers bigger fish. That is why the actor surrounded himself with vintage typewriters. There are even rumors among journalists that Tom, who hates reporters with all his heart, agrees to an interview only in one case - if you lure him with a typewriter, ask him about the collection, inquire about this or that specimen, or even give him a brand new (or rather old) model. So, a few years ago, Talking Dead host Chris Hardwick sent Tom Hanks a 1934 Smith Corona typewriter with an invitation to take part in the broadcast. He received the answer in printed form: “Dear Chris, Ashley and other damn geniuses of Nerdist Industries! Who do you think you are, deciding that I will buy into your offer only after receiving this wonderful silent typewriter from 1934! You're out of your mind if you think... that I... wow!.. what a good move she has... what a rich crimson... Stop! I'm not some small fry... and how quietly it types... Ok! I'll tell my people to contact you and set up an interview. Damn you! Tom Hanks."
Angelina Jolie: knives
Angelina Jolie has been collecting bladed weapons for many years now. The actress's collection focuses on Renaissance and Medieval knives and daggers, but she also collects other types of antique knives and swords. It would seem that this is not a very “female” hobby, however, if you think about it, it’s nothing special: why shouldn’t a woman who carried the blood of her husband (Billy Bob Thornton) around her neck in a bottle chase daggers around the world. In one of her many interviews, Jolie admitted that she keeps her treasures under lock and key - in the house where she lives large number children, it would be unsafe to keep knives in the public domain.
Keira Knightley: nail polish
The Pirates star Caribbean Sea“The passion for hoarding is also present. True, unlike her previous colleagues, she turned her attention to modernity. Keira Knightley collects nail polish. Moreover, apparently, she is not particularly interested in either the brand or the texture, because the main thing for an actress is color, and the brighter it is, the better. Let's be honest, not all experiments are successful: according to the star herself, one of her latest acquisitions is a yellow-brown varnish, in other words, the color of a child's surprise. As Kira reasonably noted, with such varnish her hands looked like paws heavy smoker, so there was no need to talk about beauty.
Catherine Deneuve: lipstick
The star of French cinema, the inimitable Catherine Deneuve, also collects cosmetics, namely lipsticks. Catherine often admits that she simply cannot pass by a stand with lipsticks in a boutique - her collection already includes several hundred copies of the most unimaginable shades. Judging by the fact that in public places Deneuve still appears with rather modest and elegant makeup, one can assume that the collection has remained untouched for many years. Well, in the end, this is not the strangest hobby, judging by the actress’s star colleagues.
Dustin Hoffman: Teddy Bears
Dustin Hoffman's collection is perhaps the cutest of all listed and not entirely masculine. The actor collects teddy bears, but, it should be noted, not all of them. Hoffman is extremely selective - his collection consists exclusively of Teddy bears. By the way, the cute little bear cubs were named after Theodore Roosevelt because he was unable to shoot a bear cub while hunting.
Rumor has it that Hoffman has an entire room in his house dedicated to bears, which is not surprising - the actor already has more than a thousand of them, and the collection is growing every day, so there is every reason to fear that the bears will soon evict the star from his apartment. But Dustin’s friends never have problems choosing a gift for a particular holiday.
Reese Witherspoon: vintage lingerie
At first glance, blonde Reese Witherspoon seems like a completely ordinary person with a hobby that any woman with decent earnings can afford - she collects antique vintage lingerie. Such a hobby is quite understandable - antique lace, silk, satin, in short - a very sexual hobby. Along with vintage knickers and slips, Reese also has a passion for antique embroidery. But another hobby of the actress causes some bewilderment: she collects plastic dishes, and exclusively from the same brand. According to Witherspoon, she simply cannot pass by the store without purchasing a package of plates, forks or cups.
Penelope Cruz: hangers
The muse of director Pedro Almodóvar and the wife of Spanish actor Javier Bardem is such a bright and original woman that, of course, she could not get carried away by any standard hobby. It’s not that the charming Spaniard could take first place in the ranking of the most original collectors, but it’s quite possible to compete for the leading position. The fact is that Penelope is collecting hangers. Wooden, plastic, multi-colored, plain... in general, whatever your heart desires. The collection currently numbers more than five hundred copies.
Claudia Schiffer: spiders
It's hard to believe, but top model Claudia Schiffer is crazy about insects, especially spiders. Claudia's passion for these not-so-attractive insects began in childhood - back then she could sit for hours watching a spider weave its web. Today, in addition to a variety of very original decorations in the shape of spiders, Claudia also has an impressive collection of dried insects. Only one question remains open: why don’t top models get live pets and start going to social events with them?
David Lynch: Dead Flies
The director of Twin Peaks cannot get carried away with ordinary things, this is quite obvious, judging by his creations. So there is nothing to be surprised that Lynch, in his free time from work, catches flies, dries them, and then sticks them on his wall... Although no, it is impossible to remain completely indifferent to such a hobby, no matter how much you want. They also say that in addition to dead flies, Lynch is also interested in chicken bones, which he also diligently demonstrates to the guests who dare to visit the director. It happens that Lynch doesn’t disdain trash... thank God, only paper waste, in order to create exciting installations from them.
Johnny Depp: everything in a row
Johnny Depp's weirdness is legendary. In choosing a hobby, the actor also decided to show off his originality and began collecting everything. Rumor has it that in his youth Johnny dabbled in collecting pigeon skeletons, bat corpses and dried bugs. True, then he switched to more harmless exhibits, including old hats. Again, according to legend, the star of “Pirates of the Caribbean” was almost kicked out of the house by his common-law wife, Vanessa Paradis, for an excessive number of hats, but in the end the matter was limited to only the “eviction” of some of the exhibits to another room. In addition to his passion for slaps, Depp turned his attention to Barbie dolls. At first, according to the actor, he entertained his children with toys, but in the end, he became so carried away that he began purchasing dolls purely for his personal collection. Johnny prefers celebrity dolls. His collection includes Elvis Presley, Beyonce, Lindsay Lohan, as well as dolls named after his beloved - Jack Sparrow and the Mad Hatter.
In the meantime, Johnny still manages to collect all sorts of items related to the writer Jack Kerouac. Depp owns not only editions and manuscripts of his works, but also the author's coat, jacket and suitcase. The actor also collects art objects - he is attracted by paintings depicting clowns, lamps and furniture in the Art Deco style.

Photo: A star losing mass and its nebula
Explanations: Fog formation around this cold star- light reflected by dust particles surrounding it. The dust originated from the star itself and is believed to consist mainly of silicon found in its outer layers. The rate of mass loss is much higher than usual for stars of this type and is sufficient to form the reflection nebula IC 2220. The fact that the central object in the image is a star can be seen at least from the cross-shaped “spikes” emerging from it. These are artifacts that arose due to the design features of the telescope.

Photo: Wolf-Rayet star in the nebula NGC 2359
Explanations: Wolf-Rayet stars are massive, extremely hot, and material is ejected from their surface at speeds of several thousand kilometers per second. As for the star NGC 2359, it interacts with gas and dust around it solar wind, generating the cosmic “bubble” visible in the photo. The shell-like layers are formed by the single star HD 56925, which is losing a significant portion of the material from its outer layers, ejecting it into a part of our Galaxy rich in interstellar gas. Such stars are unusual mainly because such an existence cannot last long.

Photo: Faint nebula NGC 6164-5
Explanations: Very hot massive stars during their short life they quickly lose mass from their surface. Mass loss is usually a fairly steady process, but some stars sometimes have sudden outbursts. The star HD 148937 has ejected large amounts of material at least twice during its life; The brightest and most recent ejection is observed as nebula NGC 6164-5 (at the center of the image), while the much fainter and older nebula "rim", visible at a considerable distance from the central star, indicates another strong ejection that occurred much earlier. earlier.

Photo: Double nebula NGC 6164-5 around a bright star
Explanations: The bright central star seen in this photo is known simply as HD 148937. But as the hottest component of a young triple system of stars orbiting each other, it represents quite a unusual object, although similar in appearance to planetary nebula. The star itself is losing mass from its outer layers continuously, but from time to time energetic flares produce the symmetrical shells visible in this image. Both stellar shells are cataloged as separate objects under the numbers NGC 6164 and NGC 6165,

Photo: Young stars in the Orion Nebula
Explanations: Image taken By space telescope Hubble does not show most of Orion Nebula (0.14 light years in diameter) and five young stars. Four of them are surrounded by gas and dust masses that were captured by the forming stars. It is possible that they all represent protoplanetary disks (“proplyds”) that can develop into planetary systems. Formations closer to hot stars appear bright, while those farther away appear darker.

Photo: First images of a real brown dwarf
Explanations: The images show a red dwarf star (Gliese 229) of 8th magnitude, located in the constellation Hare at a distance of about 18 light years. Its much fainter companion, Gliese 229B, was discovered on October 27, 1994. The semimajor axis of the companion's orbit is 44 AU. The mass of this object is about 20 - 50 times the mass of Jupiter, but its density is so great that it has the same diameter as Jupiter (128,000 km). The companion has a low surface temperature and a methane atmosphere, indicating that it is a substellar brown dwarf. The image on the left was taken in far-red light using the adaptive optics coronagraph of the Palomar Observatory 1.5-meter telescope (October 1994). The right image, taken by the Hubble Space Telescope (November 1995), confirms that the faint speck, named Gliese 229B, is indeed an object orbiting its parent star.

Photo: Protoplanetary disk
Explanations: An image of a very young star (its age is from 300 thousand to 1 million years), surrounded by matter left over from the period of star formation. The cool, reddish star has a mass equal to about one-fifth the mass of our Sun. The dark disk silhouetted against the Orion Nebula may be a protoplanetary disk from which planets form. The disc contains at least seven times more substance than our Earth, and has a diameter of about 90 billion km, which is 7.5 times the size of the solar system. The Orion Nebula is located about 1,500 light years away from us in the direction of the constellation Orion. The image was taken by the Hubble Space Telescope.

Photo: Planet around the star Beta Pictoris
Explanations: The Hubble Space Telescope image shows for the first time the interior of the 320 billion km dust disk surrounding the star Beta Pictoris. Top: Visible light image of the disk, showing the disk almost edge-on and therefore spindle-shaped. It consists of microscopic dust grains formed by ice and silicate particles. In the lumen of the disk there is one or more planets. The light of the bright star lying in the center of the disk in this frame is blocked. Bottom: False-color image processed to reveal details of the disk structure. You can see that the pink-white inner edge of the disk deviates slightly from the plane of the outer red-yellow-green disk (shown as a dotted line in the image). The simplest explanation for this phenomenon is that part of the disk is attracted big planet. The planet itself is impossible to see because it is close to the star and its brightness is perhaps a billion times less.

Photo: Ejections from a young star
Explanations: This image from the Hubble Space Telescope reveals new mysteries about the birth of stars, showing a pair of spectacular gas eruptions erupting from a young star. Above: The ejecta extend over a distance of more than a light year. The source of this structure - a young star - lies in the middle between the ejecta and is hidden by a dark cloud of dust. Nearly symmetrical gas bubbles at either end of the ejecta form where they collide with interstellar gas. Bottom left: Close-up The area around the star shows a luminous chain of gas clumps ejected by the star, like the tracer of a machine gun fire. Bottom right: This wedge-shaped structure is classic example shock wave, which occurs when a fast-moving substance collides with a slower medium.

Photo: X-ray burster (artist's drawing)
Explanations: This painting conveys the artist's idea of a double star in globular cluster NGC 66224, which is the source of powerful X-ray bursts. The object consists of a neutron star surrounded by a disk of matter and a satellite - white dwarf, the substance of which flows onto this disk through a narrow bridge. The object's ultraviolet emission was recorded by the Hubble Space Telescope in 1993.

Explanations: The development of the gas shell surrounding Nova Cygni after the explosion on February 19, 1992. Images are shown obtained by the Hubble Space Telescope on May 31, 1993 and after upgrading the system in December 1993. Nova owes its appearance to a thermonuclear explosion on the surface of a white dwarf in a binary star system.
