53 examples of Supernova in a sentence

If, like me, you're wearing a gold ring, it was forged in a supernova explosion.
This would be about a million years a second, because you have about one supernova every century.
Still others suggest that maybe this is something that formed during the death throes of a star, perhaps during a supernova explosion, as planetary material got shredded.
So under an endless rain of cosmic dust, the air is full of pollen, micro-diamonds and jewels from other planets and supernova explosions.
And it took three years to find just 42 supernovae, because a supernova only explodes once every hundred years within a galaxy.
Now, this may not look impressive, but this is what a revolution in physics looks like: a line predicting the brightness of a supernova 11 billion light years away, and a handful of points that don't quite fit that line.
This will increase by 1,000 within the first four months: 1.5 million supernovae by the end of its survey, each supernova a roll of the dice, each supernova testing which theories of dark energy are consistent, and which ones are not.
That causes an unbelievably powerful explosion we call a supernova.
Second, all the elements that had been accumulating in the core of the star, like carbon, oxygen, nitrogen, iron, as well as all of those formed in the supernova explosion, are ejected in to interstellar space where they mix with the gas that's already there.
That means that the gas it arose from had itself been enriched with many elements from supernova explosions since the universe began.
The outer layers collapse into the center, and bouncing back from this sudden injection of energy, the star explodes forming a supernova.
In extreme contrast to the million year transformation of hydrogen to helium, the creation of the heaviest elements in a supernova takes place in only seconds.
The expanding supernova shockwave propels its elemental debris through the interstellar medium, triggering a swirling dance of gas and dust that condenses into new stars and planets.
Maybe some future supernova will occur close enough to shower us with its treasure and hopefully not eradicate all life on Earth in the process.
She transformed into a supernova, and in the process releasing a tremendous amount of energy, outshining the rest of the galaxy and emitting, in one second, the same amount of energy our sun will release in 10 days.
In the process of becoming a supernova, the interior of the star collapses under its own weight and it starts rotating ever faster, like an ice skater when pulling their arms in close to their body.
That star formation may be a very important part of these supernova explosions.
Drop it near a supernova, you die.
It's been a long-standing mystery to astronomers where all the supernova remnants are.
We know that there must be a lot of high-energy electrons in the plane to produce the synchrotron radiation that we see, and we think they're produced by supernova remnants, but there don't seem to be enough.
Fortunately, GLEAM is really, really good at detecting supernova remnants, so we're hoping to have a new paper out on that soon.
No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova.
And some stars die spectacularly in a supernova explosion, leaving remnants like that.
It's so dark, that if you were to be looking at the nearest star to you, and that star were to explode as a supernova, and you were to be staring directly at it at the moment when its light reached you, you still wouldn't be able to see even a glimmer.
And that's despite the fact that a supernova is so bright, so brilliant an event, that it would kill you stone dead at a range of several light-years.
It would be a bit like experiencing a supernova explosion, but at point-blank range and for millions of years at a time.
All it takes is for a supernova to go off a few light-years away, and we'll all be dead!
And today, I want to take you on a journey that starts in a supernova explosion and ends with the air that we're breathing right now.
The vast majority of oxygen in the universe was indeed produced over the entire history of the universe in these supernova explosions.
These supernova explosions signal the demise of very massive stars.
