";s:4:"text";s:6954:" The Canis Major constellation represents the big hunter dog of Orion, the celestial hunter. VY Canis Majoris is a star in its final death throes.
It is more than 1.000 times bigger than our sun, and it is among the largest known stars in Looking for fun activities to teach kids about VY Canis Majoris?This premium worksheet bundle contains a printable fact file and 10 fun and engaging worksheets to challenge your students and help them learn about VY Canis Majoris.VY Canis Majoris was first observed and recorded in 1801 by the French astronomer Jerome Laland. VY Canis Majoris has a rotational velocity of around 300 km / 186.4 mi per second. VY CMa is also a pulsating star, so its size changes with time. Thus, because of this, it was given the designation VY Canis Majoris in 1939, the 3VY Canis Majoris is embedded within the large molecular cloud called Sh2-310. Answer and Explanation: The question is not one of if VY Canis Majoris will explore but when it will explode. VY Canis Majoris is a highly evolved star with an age less than 10 Myr although some older authors argued that it would rather either be a very young protostar or a massive pre-main-sequence star with an age of only 1 MYr and also a circumstellar disk around the star.
It is an extreme oxygen-rich and pulsating variable star.
Classes as extreme as M2.5 and M5 have been given.A very large and luminous star, VY CMa is among the Most of the output of VY CMa is emitted as infrared radiation, with a maximum emission at 5–10 μm, which is in part caused by reprocessing of the radiation by the circumstellar nebula.Since VY CMa has no companion star, its mass cannot be measured directly through gravitational interactions.
It was listed as a 7It was first described as a crimson star, while observations progressed it was discovered that VY Canis Majoris was a strong source of OH(1.612 MHz), HIn 1931, variations in VY Canis Majoris’s brightness were first described. After the star explodes, it is speculated that its remaining core will collapse and result in a black hole.The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web.Take an interactive tour of the solar system, or browse the site to find fascinating information, facts, and data about our planets, the solar system, and beyond. It has an apparent magnitude that varies from 6.5 to - 9.6, and its absolute magnitude is – 9.4.This hypergiant is losing its mass to a rate of around 30 times the mass of VY Canis Majoris is cooler than our sun, with an estimated surface temperature of around 3.490 K. Our Sun has around 5.778 K surface temperatures for comparison.
The star's death nebula is ~4500 AU in width, about fifty times larger than the star itself and much larger than our solar system.
VY Canis Majoris is the largest known star. They also produce long-duration gamma-ray bursts, which are among the most energetic events observed in our universe.When it will happen, VY Canis Majoris will explode releasing the energy of more than 100 times that of a supernova, and enormous quantities of gamma rays.This explosion will not affect Earth as the hypergiant is too far away, but if there are any planets near VY Canis Majoris which host life, it would be completely eradicated.
Hypernovas produce considerably higher amounts of energy than regular supernovas.
It has probably evolved from an O9 main sequencestar with a radius of 5 - 20 R☉. The spectral features also vary noticeably over time.
VY Canis Majoris has an average density of 5.33 to 8.38 mg/mVY Canis Majoris is located in the constellation of Canis Major. It is ejecting massive amounts of material into a surrounding nebula that makes the star blocked in the visible spectrum.
Early estimates of the temperature of VY CMa assumed values below 3,000 K based on a spectral class of M5.The calculation of the radius of VY CMa is complicated by the extensive circumstellar envelope of the star. VY Canis Majori’s radius has been estimated to be around 1.420 times greater than the sun’s radius.VY Canis Majoris’s diameter is around 1.750 times greater than the VY Canis Majoris is a red supergiant/hypergiant star of spectral type M3-M4.5.
VY Canis Majoris is a pulsating variable star situated at around 3.900 light-years / 1.2 kiloparsecs away from the Sun. The star has evolved rapidly because of its high mass.
The collapse causes a powerful energy explosion that ends the star's life. Comparison of the effective temperature and bolometric luminosity of VY CMa compared to evolutionary tracks for massive stars suggest an initial mass of The effective temperature of VY CMa is uncertain but as the spectrum of VY CMa varies, then also the temperature may vary. In the case of VY Canis Majoris, it was formed around 10 million years ago when gravity pulled swirling gas and dust together.VY Canis Majoris is a very young star, and it is believed that it evolved from an VY Canis Majoris is situated at around 3.900 light-years / 1.2 kiloparsecs away from the Sun. Earlier direct measurements of the radius at infrared (On 6 and 7 March 2011, VY CMa was observed at near-infrared wavelengths using Most radius estimates of the VY CMa are considered as the size for the optical VY Canis Majoris has been known to be an extreme object since the middle of the 20th century, although its true nature was uncertain.In contrast to prevailing opinion, a 2006 study, ignoring the effects of the circumstellar envelope in the observed flux of the star, derived a luminosity of 60,000 Almost immediately another paper published a size estimate of 1,800–2,100 Since then, the size of VY CMa has been calculated more accurately to be somewhat lower, for example 1,420 The future evolution of VY CMa is uncertain, but like the most cool supergiants, the star will certainly explode as a Alcolea et al 2013 refer to VY CMa as having the highest radius "among well-characterised stars in our galaxy", referring to the Wittkowski et al. It was listed as a long-period variable with a photographic magnitude range of 9.5 to 11.5. Molecular clouds of gas and dust are responsible for many star births.
It is bright enough to be observed with a pair of regular binoculars.Consecuentely, VY Canis Majoris is the biggest star of the constellation.
This is one of the largest star-forming H II regions which has a diameter of around 480 arcminutes / 681 light-years / 209 parsecs. The hypernova explosion is estimated to take place in around 100.000 years.
