Betelgeuse is part of the Orion constellation. It is the eighth brightest star in our sky.
For plutonium (or any other radionuclide) to decay to one eighth of its original activity, it will take 3 half-lives of the material. In one half-life, half is gone. Half will be left. In another half-life, half of the half that was left is gone, and one quarter will be left. In a third half-life, h…

Both Betelgeuse and Rigel are listed as being only 10 million yeas old, compared to the sun's 4.5 billion. Both are also expected to supernova soon, though Betelgeuse is expected to go out sooner, as it's been anticipated since 2011.

Our sun will never turn off ("die") like it does in some fictitious science fiction movies. Stars continue to fuse elements until they collapse either into a white dwarf, or explode in a supernova. Lifespans range from several million to close to 13.7 billion years. After a star burns through it's l…

The star Betelgeuse (or "beetlejuice") is a Type M red supergiant in the constellation Orion. It is pronounced "bet- L (like the letter L) -geese," meaning armpit of the giant. It is very luminous, and one of the largest stars known [See Link]. For comparison, if the star was at the centre of our s…

Betelgeuse is a red super giant, relatively luminous, and one of the largest stars known. For comparison, if the star were at the center of our solar system its surface might extend out to between the orbits of Mars and Jupiter, wholly engulfing Mercury, Venus, Earth and Mars. Astronomers believe Be…

I would like to explain that in fact, Betelgeuse is closer to 640 light-years away than it is to 425 ly. So, if it goes supernova tonight, the light from this massive explosion would take 640 years to get to Earth. So, we would observe this supernova only 640 years after it has actually happened.

Betelgeuse (also known as alpha ori) is a very large star, an M supergiant. This is because it has evolved far from the state in which stars spend most of their lives, known as the main sequence. For stars on the main sequence, which includes our Sun, there is simple proportionality between size and…
