in the middle of a nebula lies a glowing neutron star or a white dwarf with highly concentrated mass at extremely high densities.
After a planetary nebula the oxygen in the middle will make it turn into a blackhole or neutron star.
It formed the sun!!
yeesss.! I did a science project on it and got an A.!
The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
A supernova occurs.
helium and hydrogen gases
A supernova occurs.
the solar system formed from a nebula of dust, that for some reason, the middle of the nebula was compressed forming a denser solid than the dust around it. so, having a larger gravitational pull the surrounding dust was drawn towards the middle of the nebula. as it moved in the nebula began to spin and due to the law of the conservation of angular momentum as a spinning objecting compresses it spins faster. so the nebula compressed and when a star (the sun) ignited the force of this formed other areas of compressed dust and this was how the planets formed and why the solar system orbits or spins.
middle aged, in the center of its 10 billion year life cycle, as with ashes to ashes, dust to dust, nebula to nebula, musted gases to musted gases.
nebula
Yes, the first neutron star was observed in a supernova remnant. The object, named PSR B1919+21, was discovered in 1967 in the Crab Nebula, the remnant of a supernova that exploded in the year 1054 AD.
The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
