Stellar Evolution

Parent Category: Stars
Stellar evolution is the life cycle of a star. Stars start out as clouds of gas and dust. The composition of the gas and dust will determine the stages that the star may go through.
Quasars are some of the most distant and luminous bodies we can  observe. Since we measure them to be incredibly far from our own  galaxy, in the order of billions of light-years, astronomers  believe that they are several billions of years old as their light  would have taken that long to...
Quasars are galaxies which are much brighter than ordinary ones. they are as bright as 100 galaxies put together. they are also as powerful as several blackholes put together. quasars are seen as faint light from the earth this shows how powerful they are to be seen from the extreme end of the...
The black hole represents a crust in the space which swallows anything that passes through it. Even light cannot escape from a black hole! There is a particular radius for a mass to become a black hole when it is squashed. This is known as the Schwarzschild radius and for the body to become a black...
Neutron stars. Pulsars. And occasionally black holes.
First of all, there's two theories of relativity. The one on normal  relativity which indicates that an object that is moving very fast  will experience less time than one that is stable. The one on  special relativity indicates that the more gravity an object is  putted into, the less time it...
Supergiant stars are dying stars that still undergo nuclear fusion,  they are made up of hydrogen and some other elements such as oxygen  and magnesium. Neutron stars are exposed cores of supergiant stars,  they are made up of neutrons, and they cannot undergo nuclear  fusion.Supergiant stars...
The only way we'll ever know if Betelgeuse has "gone supernova" is  when we see it. Of course, by the time we see it, the event will  actually have happened some 640 years earlier, because that's how  long its light takes to reach our eyes. Despite being only about 10  million years old (young,...
Because it does not have enough mass to crush itself with it's gravity.
Neither, dark matter is an undetectable yet massive existence within our universe. It is spread out relatively smoothly, not bunching up in particular locations. For more information, search dark matter images (computer simulated), they help the visualization of it.
Black holes havent quite been explained yet. Some scientists still havent found out why black holes are created, and what creates them. But people have suggested that black holes are usually made o rubbish. (Im talking about junk that is left in space such as crashed space ships, or either broken...
Inside is unknown but around the edge is very hot.
Well, maybe. Black holes are bodies in the universe and they are so dense that nothing, not even light, can escape. Black holes can suck an entire planet whole. Use this as an example: if an inhabitated planet was in the path of a black hole, the inhabitants would be killed along with their home....
Nothing. The distortion of space and time within a black hole's  event horizon is so extreme that the only possible direction of  movement is further inward.
it is the last class
Sure, if it gets close enough, it might. By the way, any other object of sufficient mass could also "suck" the Sun if it gets close enough.\n Sure, if it gets close enough, it might. By the way, any other object of sufficient mass could also "suck" the Sun if it gets close enough.\n Sure, if it...
The ancient Greeks and Celts had mermaid myths.
yes, it is the stage where a star dies and turns into a blackhole
What you are seeing is an absence of light. You distinguish a black objects presence by its lack relative to other things.
From the unimaginable force of gravity. As you fell into a black hole, first you would be torn in half, then that half would be torn in half, then that half would be torn in half, so on and so on all the way down to every atom in your body.
Probably not. Dark matter is not believed to concentrate well in or around masses the size of stars. But it does concentrate well around galaxies and clusters of galaxies. Most of the mass of a galaxy like ours is believed to be in a sphere of dark matter in the galaxy's spherical halo.
A black table is black because all of the colours are absorbed , and none are reflected. It is the same for any other black item too, for example: A chair. Now, if a chair is red, that is because blue and green (the 2 other primary colours in light) are absorbed and red is reflected. It is the same...
not every star can turn into a black hole, because it has to meet a certain size to do so. our sun will not turn into a black hole, how ever, it will destroy our planets. many stars can turn into black holes, but only when it meets the end of its life which is when it stops burning gas.stars have to...
No. The nearest black hole is about 1,600 light years away.
No. White dwarfs, neutron stars, and black holes are three  different things. With the exception of some black holes, all are  remnants of the cores of dead stars at various degrees of collapse.   A white dwarf is the remains of a low to medium mass star  consisting of atomic nuclei surrounded...
The sun measures about 32 arc minutes as seen from earth. It is a big ball with a diameter of some 1.392 x 109 meters. Taking the sun away and sticking in a typical neutron star would mean substituting that big ball with something only some 20 to 40 kilometers in diameter. The neutron star is...
  This Kepler's Third Law problem can be solved with the following formula:   P2 = a3 / (M1 + M2)   P = period of rotation in years   a = distance between the objects in AUs   M1 and M2 = mass of the first and second objects (respectively) in solar masses   Average neutron star...
    For a thermal radiation source, the peak of the blackbody radiation curve is at a photon energy 2.8 times the temperature in electron-volts.     The temperature in electron-volts is 1/11,600 times the temperature in Kelvin.     Use E = hv to convert from the photon energy...
Here are only some of the factors: distance from their sun, axis,  and whether or not they have a moon, if so, the moons size.
black holes swallow all energy and matter around them, including  electricity
There is an upper limit to the mass of neutron stars because if the  neutron star is too massive, neutrons would be crushed by the  gravity of the neutron star, and the neutron star would collapse  into a black hole.
An x-ray telescope. They are far too small to be seen optically.
Red dwarf stars have such long lifetimes that none of them ever have yet. Presumably, they will eventually go through the white dwarf phase before cooling entirely and becoming "black dwarfs".
Pulsars have extremely short periods; in some cases seconds, in  some cases just a few milliseconds. There is no way a typical star,  with its great size (for example, a diameter of 1.4 million  kilometers in the case of our Sun) can pulsate that quickly.
No they do not. All matter in a black hole is crushed into a single point called a singularity. A point does not have any dimensions so there is no bottom. Or even a top for that matter.
They've observed the black cloud around which no light escapes that surrounds a black hole.They've observed the bending of light around the black hole, which caused two identical looking universes side by side.They've observed the galaxies rotating around them.
No. Only massive, short lived stars can supernova and only under certain conditions. The large majority or suns, including our own (yellow dwarf) will eventually burn out and become black dwarfs. However, this process takes so long the Universe is not yet old enough for us to witness the event.Nope....
No. You will not be swallowed by the black hole but you still would  not survive for very long. If the sun become a black hole it would  retain the same mass, so the orbits of the planets would remain the  same. It is only within the former radius of the sun that gravity  would be unusually...
The "boundary" you're probably thinking of is called the event  horizon. Past this point, the escape velocity of the black hole  exceeds the speed of light, meaning nothing, including light, can  escape it.
A black hole consists of three main parts: The Accretion disk, (outer edge made up of hot gasses/rock etc). The event horizon (the part that looks as though it it a huge black hole, this is because the parts moving into it are moving faster than the speed of light so you cannot see the past this...
The Earth is currently headed away from the nearest dwarf star and won't start heading back towards it until about the beginning of July. However, there's no danger of a collision any time soon; we've been orbiting it like this for about five billion years. (The nearest dwarf star is, of course, the...
after a neutron star collapses on itself
There is no way to escape from a black hole because it's gravity is infinite.
Quasars are produced by the friction in the accretion disk  surrounding a black hole and we believe that there are supermassive  black holes at the center of not just our own galaxy but the center  of all galaxies.
A neutron star is formed when a large star collapses from gravity, but, the star is able to cling on to life because as it collapses, the neutrons in the atoms that make up the star repel each other, pushing outwards against the gravitational force, keeping the star alive, but incredibly dense.
Stars are balls of gas that undergo nuclear fusion and have a core,  their light come from the energy released during nuclear fusion.  Planetary nebulae are the blown-off shells of dying red giant  stars, the light of a planetary nebula come from ionized gas and  light of other stars.
A black hole can have an electric charge if it swallows electrically charged objects, but no objects that we know of have magnetic charge. Magnets always have both a north pole and a south pole; there is no evidence that one can exist alone. A lone north or south pole would be called a magnetic...
no because it would destroy the space if it went in to a black hole
Albert Einstein predicted their existence using some pretty  complicated math. It was not until some years after his death that  we actually detected one (Cygnus X-1).
First of all, there cannot be a black hole on the sun because it's  to small, but technically speaking a star which is massive enough  for it's core to collapse and form a black hole will be a star that  is not alive any more but will still seem like a normal star for  around three hours, and...
Answer . Could very well be the spark plugs or possibly fuel injectors. I had the same problem and it was the spark plugs.. check for dead spots in your tps. also check that the resistance in your airflow meter is consistant.
Depends how close the neutrino is to the black hole.
Just an another random volunteer I guess.
The mass of a black hole is contained in a singularity, which is a  single infinitely dense point.
One, the gas (hydrogen) get pulled together by gravity, getting  denser, and finally, a star is made.
A star forms a nebula when it runs out of fuel. The star either  becomes a red giant or a supergiant, then the star would be blown  off into space either by expansion or explosion. The outer layers,  which was released into space, would become a nebula, or sometimes  a part of a larger nebula.
The brightness of a star depends (a) on its temperature, which affects the amount of radiation emitted per square meter, and (b) the total surface area. A white dwarf has a very small surface area - around 1 / 10,000 the area of our Sun.   White dwarf stars are the compressed cores of a dead star...
Firstly you get streched then you rip into two then 4 then 10 and you keep doing that until you are a stream of atoms then you get squished and then get burnt up. CAUSE OF THE FREAKIN FCC!Oh yeah that will feel good if you get sucked into a blackhole.
Gravity. When a star of 3+ solar masses collapses in on itself, gravity continues to make its matter denser and denser.
No. Neptune is a planet, so if it had a black hole on or around it, it would be pulled in.
It could be noted that the tidal force near most black holes wouldstretch you to death ("spaghettify") ... but that the larger andmore massive the black hole, the less you'd feel this tidal force.In the unlikely event you could get to a large enough black hole,could survive the intense radiation...
To be quite plain, no mater cannot escape a black hole. Not even light its self can escape the gravitational pull of a black hole.*more info*Black holes are created when a massive star (about 3-4 times the size of our sun) explode and create a supernovae. The stare will then implode on its self...
Scientists "see" things through specialized equipment that identify waves that are invisible to a human eye i.e. microwaves, gamma waves, etc.   Also because we are in the Milky Way, right? SO There are many stars in our galaxy. So, they can see it because it was a big black gap right in our...
no the galaxy is way to big for a black hole to do much in fact we  now know that there is a supermassive black hole in the center of  our galaxy right now.
It sucks it in and packs it into a great big ball of extremely dense matter which is why everything is pulled into it in the first place.
In fact, black holes cannot be directly viewed. They can only be  located by seeing how much radiation is coming from a certain point  in space. The black holes cannot be viewed directly because they  absorb the electromagnetic radiation that goes near them.
Black holes,were theorized since the 1800's,it was predicted byEinstein's theory that they were really real.Since then this forcedastronomers to think such a thing is real,and yet they are,butthere very rare to find,so we don't really know what telescopediscovered a black hole.So we thing the Hubble...
For a few days, the supernova will shine as bright as an antire galaxy - on the order of 1011 times the brightness of our Sun. It is also very powerful killing any being that crosses it's path and destroying stars and other planets too.
an emission nebulae is an object from space
Light is not only attracted to a black hole, in fact, its attracted  to you, to me and to everything made of matter in the universe. The  problem is that light is affected by gravity, and the black holes  have so much that light significantly change trajectory or the  black holes absorb the...
they are called super novas
The "no-hair" theorem states that black holes have only three  properties for an outside observer: charge, mass, and spin. In  other words, given two black holes with these three properties  being identical, no other information could be obtained to tell  them apart - for example, whether one...
We have never actually been able to stick a thermometer in one so this questing is a Little hard to answer with a any reliable reply.
yes, there is actually a giant black hole in the center of our galaxy, but don't worry because we are safely orbiting around it. A black hole is basically really really really dense material, which forms a blob where the gravitational pull is so stong nothing can escape it, not even light. It can...
Scientist believe that stellar evolution contained only hydrogen  and then helium.
Think of a house. This house we're talking about has one main support beam, and as time passes, it begins to need something to strengthen said support. A star is a lot like a house with a bad support beam. It uses its own fuel to keep burning and avoid failing. A house would need workers to put...
A quasar is a ring of dust and gas at the center of a galaxy around  its black hole, as the ¨stuff¨ gets closer to the black hole,  friction heats it, giving it an either red, orange, yellow, or  white color.
No, black holes absorb all light, so they are virtually invisible. The only way they can be "seen" is by measuring the gravity around it.
Gravity takes the form of a field around an object with mass. The mass 'curves' space time around it, causing nearby objects to be attracted towards it. Therefore gravity does not need to 'escape' from a black hole, the strong gravitational field around it is the reason other things cannot escape...
They do the opposite, they stretch you.
It is postulated that a supernova explosion was the catalyst which formed our Solar System.
            Because when someone gets hit in the gouche you poop yourself
That's easy! We don't. So far, no sign of the proposed "dark matter" has been discovered, nor have the properties of "dark matter" been firmly defined. The concept is still evolving, and will do doubt be extensively modified in the coming years.
Most Black Holes are created when a star that has 20 times the mass of our sun dies. In a stars life there is a constant war between pressure pushing out and gravity pulling in and when it dies it the outer part is thrown into space and the inner core collapses into itself, creating a black hole.
there really is no way of knowing for sure at least not with thetechnology we have now but there are a lot of theories ranging frommassive seismic events like earthquakes and volcanic eruptions allthe way to releasing demons from hell.
well black holes are some of the weirdest things in the universe  even Albert Einstein said that they are so weird the nature  shouldn't even allow them to happen
Your nose is a tiny bit bigger than your eye.
no, they are not gateways
Because a white dwarf star is the core leftover from a bigger star and the core is the densest part of the star so although the star is smaller than the sun it has a similar mass as it is more dense
outside the solar system at least, probably a few light years away
