Sentences with phrase «massive stars burn»

Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years.

Once known as a frozen star, a black hole is formed when a massive star burns out and collapses upon itself, ultimately producing gravitational energy so powerful that not even light can escape from it.

Neutron stars are ultra-dense balls of neutrons, subatomic particles left behind when a massive star burns out and collapses.

A typical supernova occurs when a massive star burns up all of its hydrogen fuel and its core collapses.

Wilson knew that when a massive star burns up the last of its fuel after some 10 million years, its core rapidly implodes, pulling all of the star's matter inward.

Not exact matches

For the first time, scientists using NASA's Hubble Space Telescope have witnessed a massive object with the makeup of a comet being ripped apart and scattered in the atmosphere of a white dwarf, the burned - out remains of a compact star.

Another possibility is that a massive pulse of burning carbon from the center of the star, emulating outwards, eliminated the lighter elements.

This massive blue star should have burnt out tens of millions of years ago, but it's still going strong.

It's not clear how long it will take for the stars to fully merge, or what will happen when that occurs: Some models of stellar evolution suggest the merged star could explosively release a massive amount of energy, while others hint it could simply burn through its fuel more quickly than each star would on its own.

A supernova — the explosion of a massive star after it burns through its fuel — would have to happen within 0.13 light - years of Earth, and the closest star big enough to go supernova is nearly 147 light - years away.

According to this model, the violent wind that creates a planetary nebula is also the engine that transforms a bloated red giant into the burnt - out cinder of a white dwarf, a metamorphosis common to all stars of low and intermediate mass — stars up to eight times more massive than the sun.

Supernovae are massive explosions that happen when a star burns out.

But observations beginning in 2014 from NASA's NuSTAR and other space telescopes are showing that some ULXs, which glow with X-ray light equal in energy to millions of suns, are actually neutron stars — the burnt - out cores of massive stars that exploded.

(Theoretically, more massive stars would burn faster.)

This is a counter-intuitive result, as more massive stars have more fuel to burn and might be expected to last longer.

Because the Universe originally lacked metals (elements heavier than lithium) that cool collapsing gas clouds today, the earliest stars were more massive and burned much hotter than even the largest stars we study today.

Many now believe that most, if not all, of the first generation of stars (Population III) that formed from the gas and dust created by the Big Bang were massive, fast - burning, short - lived, and composed only of the four lightest elements, hydrogen and helium with traces of lithium and beryllium.

Researchers using NASA's Hubble Space Telescope have observed, for the first time ever, an enormous object with the composition of a comet being shredded and scattered by a white dwarf, the burned - out husk of a massive star.

These massive, hot stars burned bright for a short time, emitting so much energy in the form of starlight that they pushed nearby gas clouds far away.

Exceptions include a number of planets discovered orbiting burned - out star remnants called pulsars, such as PSR B1257 +12, [14] the planets orbiting the stars Mu Arae, 55 Cancri and GJ 436, which are approximately Neptune - sized, and a planet orbiting Gliese 876 that is estimated to be about six to eight times as massive as Earth and is probably rocky in composition.

As the star is more massive than Sol, it has evolved faster into a helium - burning «clump» giant, possibly within five to eight billion years since hydrogen ignition (see Kaler's Stars page on Arcturus).

Because they are so massive, O - type stars have very hot cores and burn through their hydrogen fuel very quickly, so they are the first stars to leave the main sequence.

While other, more massive stars only burn through the hydrogen at their core before coming to the end of their lifetimes, red dwarfs consume all of their hydrogen, in and out of their core.

Fear X didn't so much crash and burn as stall on the grid, bankrupting Refn's production company Jang Go Star and leaving him in massive personal debt (at one point he owed his bank $ 1m).

A star is a massive ball of burning gas whose main function is fusing hydrogen into helium.
