Sentences with phrase «star ran out of fuel»

Not exact matches

A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova.

When a star runs out of hydrogen fuel in its core, it expands into a bloated red giant.

Astronomers figured this must be a short - lived phase, because a normal galaxy forming stars that fast would soon run out of fuel (gas and dust).

In the first stage of this process, the more massive star of the pair begins to run out of fuel, transferring its outer layers to its less massive companion — which is destined to become the magnetar — causing it to rotate more and more quickly.

This immediately raised the question of what happened to much heavier stars when they ran out of fuel — did they go on contracting for ever until they became what we would now call a black hole?

This star - making frenzy gives rise to galactic wind that pushes out more gas than the system keeps in, leading astronomers to estimate that M82 will run out of fuel in just 8 million years.

Coupled with the fact that 98 % of all stars become white dwarfs when they run out of nuclear fuel, he says that suggests «the fraction of stars that create rocky planets is high».

As stars run out of hydrogen fuel and burn helium instead, their luminosity waxes and wanes during several phases of pulsation, interspersed with times of relative calm.

When a star runs out of hydrogen fuel its core collapses inward under gravity and, hitting rock bottom, sends out a shockwave that blasts away the star's outer layers as a supernova.

When a star runs out of nuclear fuel, for example, the waste that remains collapses in on itself, fast and hard.

First, if a star grows massive enough, its nuclear fires can no longer overcome the crushing force of its gravity, in which case it runs out of fuel and collapses.

What happens to a star when it runs out of fuel at the end of its life depends on its mass.

Astronomers aren't sure why, but they posit that the tiny galaxy ran out of the gases that fuel star birth early on.

When a large star runs out of nuclear fuel, the core collapses in milliseconds.

When the nuclear reactions that power them run out of fuel, the stars can no longer resist their own intense gravity; they collapse and trigger the massive explosions called supernovae.

The explosions drive huge amounts of gas out of the galaxies and with most of the rest consumed in star formation, the galaxies soon run out of fuel.

After 10 billion years of guzzling the hydrogen in its core, a sun - size star runs out of nuclear fuel and becomes unstable.

When a star runs out of hydrogen fuel in its center, the core contracts and heats up, inflating the star into a bloated red giant.

Most occur when massive stars run out of nuclear fuel.

«In a few billion years, when the Sun has run out of fuel and the solar system has ceased to exist, TRAPPIST - 1 will still be only an infant star.

A black hole is formed when a massive star starts running out of nuclear fuel at its interior (mainly hydrogen and helium) and begins to collapse under its own gravity.

The glowing gaseous shrouds in the nebula were shed by the central star after it ran out of fuel to sustain the nuclear reactions in its core.

When a massive star runs out of nuclear fuel, it collapses under its own weight and forms a black hole.

A pulsar is formed when a massive star runs out of nuclear fuel and dies in a cataclysmic explosion called a supernova.

When a very massive star begins to run out of hydrogen and other nuclear fuels, it can collapse so suddenly that almost all its electrons are driven into nuclei.

When a star less than eight times the mass of our Sun runs out of the supply of hydrogen fueling the thermonuclear reaction raging in its stellar core, it may transform into a red giant instead of ending its life in a dramatic supernova explosion.

The idea behind the death of a massive star is relatively straightforward: It gets old, runs out of fuel, collapses under gravity and then explodes as a supernova.

Eventually, however, the hydrogen fuel that powers the nuclear reactions within stars will begin to run out, and they will enter the final phases of their lifetime.

These are black holes that are a few to a few dozen times the mass of our sun that were likely formed by the death of very massive stars after they'd run out of fuel and exploded as supernovas billions of years ago.

All stars, including our sun, will eventually run out of the hydrogen gas that fuels the nuclear fusion reactions in their cores.
