calculates how long these nuclear reactions take to produce iron, and how much iron black dwarfs of different sizes need to explode. He calls his theoretical explosions "black dwarf supernova" and calculates that the first one will occur in about 10 to the 1100th years. "In years,...
What supernova will happen in 2022? In 2022—only a few years from now—an odd type of exploding star calleda red novawill appear in our skies in 2022. This will be the first naked eye nova in decades. And the mechanism behind it is fascinating as well. This story really begins 10 ...
“We hope that it happens any day now,”Rebekah Hounsell, a nova researcher at NASA’s Goddard Space Flight Center, told theIndianapolis Starin early September. But astronomers are careful to say that the blast can’t be exactly predicted. “The timing of whe...
It’s this reaction that Caplan is simulating, both to measure the rate of accumulation of iron in the stars and the tipping point where the amount of iron triggers a timely death in stars of different sizes. The last, smallest “trick candle” supernovae will happen about 10 to the 32...
Our sun will not die anytime soon. (Image credit: MARK GARLICK/SPL via Getty Images) Jump to: Sun death Q&A with an expert Why? What will happen? No supernova Additional resources If you worry about when the sun will die, never fear: that moment is billions of years away...
What will happen in 100 trillion years? And so, in about 100 trillion years from now, every star in the Universe, large and small, will be a black dwarf. An inert chunk of matter with the mass of a star, but at the background temperature of the Universe. So now we have a Universe...
What does it mean when there's a rainbow around the sun or the moon? What will happen to the earth once the sun dies? What is a supermoon? Which two phases are gibbous moons? What is a lunar crater called? What will happen when the Sun turns into a red giant? What conditions are...
Designing ships or electrical substations is no easier than creating web forms and serving CRUD requests. There is competition for IT personnel, there are not enough of them. And how did it happen that the right number of developers have not been trained for 70 years? There are enough enginee...
Then there’s just the fact that we can see the expansion of the universe, that we can map that out over time, is amazing. I don’t even know if I really talked about this in the book, but when we look at very distant supernovae, solar explosions, they appear to be happening mor...
with the supernova ofHendrix's genius, but a practice schedule such as his and a restless, fidgety sense of adventure that you can still hear in his voice as he joins us on the phone, would soon make light work of the pentatonics and the blues scale. He sought out more. More was ...
