Not exact matches

Then light was liberated, and then gravity created the first stars and galaxies, then billions of years later, a local star went supernova and seeded the local nebula with heavier elements, elements necessary for life, elements that were not created during the Big Bang, then the sun was born, then the planets coalesced, and billions of years later some primate wrote a story about how the Earth was created at the same time as the rest of the universe, getting it wrong because that primate did not have the science nor technology to really understand what happened, so he gave it his best guess, most likely an iteration of an older story told prior to the advent of the Judeo Christian religion.

Before 1987A, astronomers thought that only puffy red stars known as red supergiants could end their lives in a supernova.

At first, astronomers suspected that 1987A was a class of supernova known as type 1a — the detonation of a stellar core left behind after a star like the sun quietly sheds gas at the end of its life.

After shining for many millions of years, stars end their lives, mainly, in two ways: very high mass stars die very violently as supernovae, while low mass stars end as planetary nebulae.

Most stars end their lives either slowly fading away or exploding as a supernova.

These outflows are driven by the life and death of stars, specifically stellar winds and supernova explosions, which collectively give rise to a phenomenon known as «galactic wind.»

These stars are rapidly working their way through their vast supplies of hydrogen, and have only a few million years of life left before they meet a dramatic demise and explode as supernovae.

Astronomers know that while large stars can end their lives as violently cataclysmic supernovae, smaller stars end up as planetary nebulae — colourful, glowing clouds of dust and gas.

Such stars end their brief lives in titanic supernova explosions, so supernovae in Carina must also be twice as frequent as had been assumed until now — and the same might be true for other star - forming regions in our galaxy.

(When big stars reach the end of their life, they explode as supernovae, leaving neutron stars or black holes behind.)

At the end of its life, a massive star inevitably explodes as a supernova.

These neighbouring bubbles eventually merged to form a superbubble, and the short life spans of the stars at its heart meant that they exploded as supernovae at similar times, expanding the superbubble even further, to the point that it merged with other superbubbles, which is when the supershell was formed.

Sobral adds: «But star formation at this rate leads to a lot of massive, short - lived stars coming into being, which explode as supernovae a few million years later.

And then I also thought about the fact that over the history of the life of the universe, neutrinos are not just produced by the sun, but when stars explode in a supernova, the most brilliant fireworks in the universe, as brilliant as those fireworks are, less than 1 percent of the energy of the star is coming out in light; 99 percent is coming out as neutrinos and so neutrinos are being, [and] every time [a star explodes there's] an incredible burst of neutrinos.

Some of these early stars were huge, a hundred times as massive as the sun, and lived short, spectacular lives, dying in gigantic explosions known as supernovae.

After exploding as a supernova, the star would have faded from view within a year or so — and eventually from living memory, until, 25 years ago, a radio telescope near Canberra, Australia, found its curious remains.

Caption: The colors represent the relative amounts of short - lived radioactive isotopes, such as iron - 60, injected into a newly formed protoplanetary disk (seen face on with the protostar being the light purple blob in the middle) by a supernova shock wave.

Eventually, WR 31a will end its life as a spectacular supernova, seeding the cosmos with stellar material expelled that will later nourish a new generation of stars and planets.

Scientists have long suspected that a pulsar — a rapidly spinning, superdense neutron star — was born when a giant star ended its life in a cataclysmic supernova explosion observed in late summer of 1181, as suggested by Japanese and Chinese historical records.

A new study led by Keiichi Ohnaka, a researcher at Catholic University of the North in Chile, sought to understand how the distant red supergiant star Antares manages to expel so much matter off its surface as it nears the end of its life and nears its finale as a spectacular supernova.

Types Ib and Ic are believed to correspond to stars ending their lives (as Type - II supernovae), but such stars would have lost their hydrogen before, and so hydrogen lines don't appear on their spectra (more discussion).

Those first stars led hard and fast lives, burning bright and dying quickly as supernovas.
