UY Scuti Facts

These hypergiant spectral classifications are very rarely applied to red supergiants, although the term red hypergiant is sometimes used for the most extended and unstable red supergiants like VY Canis Majoris and NML Cygni. The "red" part of "red supergiant" refers to the cool temperature. 2 days ago · In the southern hemisphere, in the constellation Canis Major, lies a very young, very massive red hypergiant star called VY Canis Majoris (VY CMa). A .

UY Scuti is a red supergiant star located in the constellation Scutum. It is one of the largest known stars, discovered since This discovery was quite overwhelming, and how to make a chocolate mousse pie a period of time UY Scuti held the title of the biggest known star in the Milky Way.

UY Scuti is a red supergiant star, which is usually an aging star. Stars with a big enough mass transform into red supergiant stars. They are the largest known type of stars. They usually form when a star runs out of hydrogen fuel in their what is a hypergiant star and begins collapsing. The outer shells of hydrogen around the core get hot enough to begin fusion.

The shells then expand, and the now cooler star takes on the red color. It is situated just northeast of the famous Eagle Nebula Messier Also home to the famous Delta Scuti variable star, the Scutum constellation contains many relatively bright deep-sky objects that are quite popular targets among stargazers.

However, recent estimates in have made the planet a bit smaller due to its change in temperature. The radius has dropped — it now has times the radius of our Sun. If now it has a radius of approximately Even before these new estimations, UY Scuti was already surpassed by Ra1in mass at least. Regardless, UY Scuti is still one of the biggest known stars and if UY Scuti were placed in the Solar Systemreplacing our sun, its photosphere would reach the orbit of Saturn.

Current models based on stellar evolution suggest that UY Scuti has begun to fuse helium. It continues to fuse hydrogen in a shell around the core. When the star will finish fusing the heavy elements, the core will start to produce iron thus disrupting the balance of gravity, and radiation in its core will result in its collapse thus explode into a supernova.

Scientists believe that UY Scuti will evolve back to hotter temperatures and become a yellow hypergiant, luminous blue variable, or a Wolf-Rayet star. This will not affect us since the necessary distance in order for a supernova to do so, would require it to be around 50 light-years away from us. Currently, we do not know if there are planets orbiting around UY Scuti. Even if it has a habitable zone the radiations emitted by what is the zip code of chandigarh india enormous star will sterilize everything.

It what is a hypergiant star have been possible for life to evolve around these hypothetical planets before the star grew to such sizes. When UY Scuti goes supernova, it will definitely be a sight to see. However, estimates are not precise when this will happen.

The star will continue to be monitored and studied regardless. It Is a hypergiant with a radius around 1, times larger than the Sun. Home » Stars » UY Scuti. However, the star was better documented in with the help of greater technological equipment. Data revealed that UY Scuti was around 7 to 10 times more massive than our Sun, and had a radius approximately 1. It has a radius of 1. UY Scuti is located in or galaxy the Milky Way, at about 5.

UY What is a hypergiant star changes its brightness but it can be viewed from Earth as it is a pulsating star. It has an absolute magnitude of Because of its distance, its brightness how to make fabric roman shades instructions only ranked 9 th in magnitude.

It is not known if there are planets orbiting around UY Scuti, but even if they were, radiation from UY Scuti would quickly make them uninhabitable. The pulsation of UY Scuti has a period of about days.

Because of this pulsation, its exact size also varies, making an exact estimation difficult. The temperature on UY Scuti is estimated to be around 3, K. It is believed that UY Scuti has begun to fuse helium and will eventually go supernova.


Jul 26,  · The star lies near the center of the Milky Way, roughly 9, light-years away. Located in the constellation Scutum, UY Scuti is a hypergiant, the classification that comes after supergiant, which.

A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own thismestory.com nearest star to Earth is the thismestory.com other stars are visible to the naked eye at night, but due to their immense distance from Earth they appear as fixed points of light in the sky. The most prominent stars are grouped into constellations and asterisms, and many of the brightest.

Answer: The largest known star in terms of mass and brightness is called the Pistol Star. It is believed to be times as massive as our Sun, and 10,, times as bright! In , it was suggested that the Pistol Star was so massive it was throwing off the mass that actually created the Pistol Nebula. Observations from the Hubble Space Telescope in confirmed the relationship between the star and the nebula. Astronomers are currently unsure how a star this massive could have formed or how it will act in the future.

The Pistol Star appears as the bright white dot in the center of the image shown above. The star has enough raw power to blow off two expanding shells of gas which are false-colored magenta equal to the mass of several times our Sun.

The largest shell is so big 4 light-years it would stretch nearly all the way from our Sun to the next nearest star. The outbursts which created the shells seen by Hubble are estimated to be only 4, and 6, years old, respectively. Despite the mass loss by the star when it ejected this material, astronomers estimate the Pistol Star still has a mass of times that of our Sun, and may have started out with as much as solar masses of material!

The star is 25, light-years away from Earth. Despite this great distance, the star would be visible to the naked eye if it were not for all the dust between it and the Earth. As of January , we now know about some other really big stars. One is called Eta Carinae. It has a size about times that of our Sun, a mass about times that of our Sun, and is about 4,, times brighter than our Sun.

And, yet, we do not think it is the biggest! Recent observations of a star called VY Canus Majoris show that it has a size between and tims the size of our Sun! However, this star is only about , times brighter than our Sun and 30 or so times more massive than our Sun. So how can it be so big? It is in a stage of its lifecycle called a red hypergiant, and while it is very big, it is rather cool in temperature compared to our Sun.

VY Canis Majoris is located about light-years away from Earth. A site for ages 14 and up. Laura A. Whitlock Curator: J. Privacy Policy and Important Notices. Return to the StarChild Main Page.
