When the star representing Orion's knee burn out and what happened to it?
86558
Neither of the stars representing Orion's knees have burned out and both are still in the night sky. His right knee (on our left) is the star is Saiph ans his left knee (on our right) is Rigel.

When a star runs out of nuclear fuel, and therefore continues to lose energy from the surface (it is emitting light energy), while not replacing the lost energy through nuclear fusion (no more nuclear fuel), gravity will win out over internal pressure and the star will contract slowly or collapse quickly depending upon the details of the internal structure and composition. Gravity wins out over the internal pressure of the star, because that pressure was produced by a normal, hot gas, and that gas is losing energy as the star radiates energy from the surface. \n\nThe star may thus end up as a black hole.

Orion is directly adjacent to the consetllations Taurus and Gemini.  The sun is in those constellations in May and June (respectively), and hence that means you can't see Orion because the sun is too close.  June's about the worst month possible to try and see Orion, unfortunately.

OK, I just went look outside.  At midnight Orion will be nearly straight up.  Three bright stars in a line are Orion's belt.

I'm afraid it won't explode now.\nIt won't go and explode as a nova or super-nova unless something real bad happens and it gets a denser core.\nOur star won't explode until at least 5 billion years time, unless anything makes it do it.\nThe term nova means very large explosion. But our star won't explode it will widen with a little explosive force and all of it's gaseous surface and mid layers will blow off.\nOur star is an M class (G Medium class) a super-nova will only happen with L class stars (O Large class) + (M Small class) the M and S class have novas only when they collide it is likely to be explosive as the stars are young and hot.\nThe main course of nuclear fusion is:\nD+T=4He+1n or 3-2H+2-1H=4He-3.5MeV+1n-14.1/14.2MeV\nThe sun will not explode in at least 1 billion to 5 billion years!

falling star means comet.

"Betelegeuse" or "beetle-juice" in the constellation of Orion is a beautiful red giant star that has the color of its name.( it has a fiery deep red hue )\n\nIt is at the upper left corner of Orion. \n\nit is also one of the brightest stars in the sky.

Orion constellation, with three bright stars forming its belt, "las tres Marías" (The three Mary´s). Next to the belt, you will find Orion´s nebulae, a spiral galaxy, like our own. The shoulder of Orion is characterized by Rigel, a bright reddish star.\nClose to Orion, is Can Majoris (the great dog) featuring Sirius, the brightest night star in the whole observable sky from Earth. \nTo the other side of Orion (i.e. to its left and closer to the horizon), there´s a "V" shape with a nice red star (Aldebaran) which represents the eye of Taurus (The bull). \nLeft to Taurus, there´s a beautiful open cluster called The Pleyades (in the story, I think the brightest stars  represent seven sisters, but you´ll surely be able to count many more). \nIn the opposite side of the sky, you will find the Southern Cross (La cruz del sur). You can recognize it because of the four bright stars defining a clear cross. If you extrapolate the long axis of the cross four times toward where the cross is pointing, you´ll find the celestial northern pole: the point around which all the stars revolve during the night in the southern hemisphere. Besides, if you draw an imaginary line from that point in the sky to the ground, you´ll get South. An excellent way to get orientated in the field. To a side of the cross, you´ll see two bright stars: alpha and Beta Centauri. Alpha is the closest star to the Earth. \nMost of these features are more prominent during summer, but you can also see them in winter fro a brief period. \nAlso during winter, one of the best constellations is Scorpius, featuring Antares, the Red Giant. \n\nThat´s all I recall. \nIt´s a very interesting sky! Consult your charts to get the most out of it. \nHave fun!

If you mean comet Shoemaker-Levy 9, I can tell you that its various bits collided with Jupiter in July of 1994, after the comet broke up.  I don't have any footage or pictures, but you should be able to find some nice shots online now that you know its name.  Good luck!\n\nAdditional:  I did some digging for you.  I haven't found any footage, but here's a site with a lot of good pictures for you.

Since I have a feeling Yahoo won't let me post many things about this, I figure, the websites below will be more helpful.\n\nIn the first link, you're gonna have to copy and paste and put in m*sterbation for the stars. Or just go to wikipedia and search for m*sterbation.

A huge, old star implodes and becomes extremely dense, such that even light cannot escape its gravity. See more through the link below.

No, main sequence stars (like our sun) last for about 10 billion years. It has lived for about 5 billion years or so, which means the sun has another 5 billion more years to live. After those 5 billion years are over the fusion process is stopped (due to the lack of hydrogen). The star collapses on itself and makes the star even hotter. All that heat fuses the helium and the star expands into a red giant. It will last in this form for another 100 million years or so. Then the outer layers of the red giant comes of creating a planetary nebula. Then after that gas is gone all that is left is the hot core or the white dwarf. The white dwarf cools and becomes a cold dead core (Black Dwarf)

Are you talking about the "Iron Mistress"?\nLegend has it that it was made out of a falling star, or as more commonly known as a meteor.

There is no fire on the sun.  Our star is converting hydrogen into helium (which is nuclear fusion and thus creates heat) because it is so massive that the atoms its made from are being compressed by its own gravity.\n\nEventually, it will run out of fuel and stop "burning" all together, becoming a white dwarf, then a black one.\n\nLarger stars will explode and disperse their materials (the things you and I are made of) across the universe.  The largest will become black holes and try to fix the mess created by the others.

There is no oxygen in space, so you couldn't light a match. I bet if you could though, it would burn in a sphere.
