May 2015 - A Dense Intruder

Report #3 - April 2015

The Deadliest Ticking Time Bomb 

 

SC Messier uncovers the most dangerous celestial body in the universe: VY Canis Majoris; a red hypergiant star whos diameter is close to 1.5 billion miles, making it one of the largest stars known to man. Place VY Canis Majoris in the center of solar system and it would reach all the way to Saturn's orbit! With its surface being close to 3200 degrees celsius (5,8000 degrees fahrenheit), this star has a luminosity of about 250,000 to 500,000 times greater than our sun. The crazy doesn't stop there; VY Canis' mass is about 20 to 40 denser than the sun, and estimated to be 10 million years old! Named after its located in the constellation Canis Major, this hypergiant is fortunately 4,900 light-years away from our solar system, putting great distance for what is to come. 

VY Canis Majoris has aleady shed over half its mass hence the cloud-like gaseous envelope that enshrouds the star.

Can't believe the size of VY Canis Majoris? This video will help you visualize how HUGE this hypergiant really is.

Our sun

It'll all start out with a tight battle between two forces: gravity and fusion. This battle will last for a couple million year until the star runs out of energy for the nuclear fusion reactors to "pump out." With gravity's victory, the star's core decreases in size and mutates into a young black hole instantaneously, inhaling all the remains VY Canis Majoris. The black hole won't be able to keep up though, hiccuping its feast of the hypergiant's gaseous material, blasting big energy rays into space. 

 

Then... BOOM!

 

VY Canis Majoris, the largest star, explodes, shooting outward 100 times more energy than what our sun would produce in a year; all in less than a second! These bursts of beams, or rays, of energy (known as gamma ray bursts) move lightning fast, 70,000 kilometers per second, annihilating anything in its path in a blink of an eye. These gamma rays are strong enough to vaporize our planet and still continue full speed ahead, unphased, slash atoms apart, crush neutrons, or mold protons and electrons together. Since VY Canis Majoris is so large, its explosion is predicted to leave behind a black hole instead of the standard neuron star since, thanks to gamma rays, nuerons would be crushed during the initial "boom." Such a star death wouldn't be titled a "supernova," but instead a "hyerpnova." Hypernovae emit more energy than 100 supernovae combine, creating great numbers of gamma ray bursts. 

What is to Come? Pure Destruction

Watch the extreme process of VY Canis Majoris' death step-by-step in further detail.

 

Thankfully, VY Canis Majoris' death won't take place for a least another 100,000 years, and even if it did, its massive explosion wouldn't affect us, for we are simply too far away. Only ten hypergiants, like VY Canis Majoris, are known to exist in the Milky Way. Hypergiants in general tend to expel their energy faster, decreasing their life spans to several million years instead of several billion, like most stars.
