A. " This is when a supernoma—the last stage of an exploding star—ejects material during the explosion, which then falls B. ack into the supernova, C. reating a black hole. 2Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist. It's ...
When was Betelgeuse discovered? How big is a supergiant star? What does a protostar look like? What causes supernova? When did the planetary nebula NGC 6302 explode? What can a red giant star become? Can two planets crash and cause a supernova? If so, what happens after that?
The super-old stars are surprisingly pure, and contain material from an even older star that perished in a gigantic explosion called hypernova. The oldest stars ever discovered are in ‘The Bulge’ in the centre of our Milky Way. (Image: ANU Youtube) The Milky Way formed around the ol...
When was VY Canis Majoris discovered? What kind of star is Rigel? What is the first magnitude star in Piscis Austrinus? Which event marks the beginning of a supernova? A) the onset of helium burning after a helium flash in a star with mass comparable to that of the sun B) the sudden...
The find could have important implications for our understanding of the structure of the universe. Some white dwarfs explode into asupernovawhen they die, and astronomers use these blasts todetermine how far away they are. “Over the last decade, there have been renewed questions ab...
But then, when it was discovered that the universe was actually accelerating in its expansion, we had to add a new component to the universe. We had to revise our understanding and put in this thing called dark energy. And dark energy is something that’s making the universe expand faster...
It was a big moment for our cosmos when the first stars awoke, but it's an elusive one for scientists.
Those nebulas can persist for ages, but if given a kick — say, from a nearby supernova shock wave or, in a more relevant example, the complex gravitational interactions as two galaxies fly through each other — they can start to collapse in on themselves, fragmenting and condensing to for...
I've been in contact with someone at AMD and have submitted a video with what was going on with my 7. I discovered it happened if you have a resolution that either isn't the exact same as your other monitor or the refresh rate isn't a multiple of 60. I was able to e...
