Bellatrix is a variable star, which fluctuates a little in brightness. Where did the myth of Bellatrix come from?Īnother myth about the two comes from South America: among the Amazon tribes Bellatrix is the Young Boy in a Canoe with an old man, the star Betelgeuse, chasing the Peixie Boi, a dark spot in the sky near Orion (also known as the Fish Mouth). Bellatrix is a B2 III variable star with a temperature of 22,000K, and whose brightness ranges between apparent magnitudes of 1.59 and 1.64. Its location close to the sky’s 10th brightest star, an enormous red giant called Betelgeuse, makes it one of the easiest stars to recognise, with Bellatrix best seen in December and January. The dust and gas heat up and use pressure to transform into a star. A nebula is a cloud of hydrogen and dust particles in space. The brightness is 4000 times greater than the sun itself making it the 26th brightest star Bellatrix closer to us than any other star in the Orion Constellation. How is the star Bellatrix different from other stars? Bellatrix is now coming to the end of its current lifecycle and willl soon evolve into an orange giant within a few million years Nothing is able to come out of a black hole, and this will be the last stop on the course for Bellatrix. When does Bellatrix come out of the black hole? When compared to our sun’s mass, Bellatrix has 8.6 times more mass than our sun. Fact Tableīellatrix has 5.75 solar radii – it almost has six times our sun’s radius and almost twelve times its diameter. Is Bellatrix brighter than the sun?īellatrix, the “Amazon Star”, is a star much like our Sun but only about ten times more massive and 4000 times brighter than the Sun….Bellatrix. ![]() Instead of creating a supernova, the star implodes, forming a black hole. When the core collapses, the blast wave slams into the dense material above, which thwarts the explosion. When the cores collapse to form dense stellar objects called neutron stars, they blast off the outer layers of the star in a supernova. The collapsed star becomes what we call a black hole. Therefore, if light cannot escape, neither can anything else. Both objects are cosmological monsters, but black holes are considerably more massive than neutron stars.Īccording to Einstein’s theory of relativity, nothing in the universe can travel faster than light. Neutron stars are dead stars that are incredibly dense. Is a black hole a neutron star?īlack holes are astronomical objects that have such strong gravity, not even light can escape. Astrophysicists say we’d have to be within 50 light-years of a supernova for it to harm us. Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Will the Betelgeuse supernova destroy Earth? No. Heavier stars burn through the nuclear fuel in their cores in a hurry, so they produce far more energy than stars like the Sun. The key to the star’s power is its mass - about nine times the mass of the Sun. It is inevitable at the end of the life of a large star when all stellar energy sources are exhausted. The gravitational collapse of a star is a natural process that can produce a black hole. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole. Neutron stars have an upper mass limit of 2 to 3 solar masses. What kinds of stars end up as black holes? They are the natural consequence of the evolution of massive stars. Which star is likely to turn into a blackhole? To become a black hole, the material left over by the supernova explosion would have to equal more than 3 solar masses. If Betelgeuse does explode, it could become either a neutron star or a black hole. Will Betelgeuse turn into a black hole or neutron star? 8 Where did the myth of Bellatrix come from?.7 When is the best time to see Bellatrix?.6 How is Bellatrix different to the sun?.2 Which star is likely to turn into a blackhole?. ![]()
