Objects in the universe

The complete star doesn't explode but it leaves it's core behind. That's the white dwarf, neutron star or black hole, depending on the mass of the former star.
Way too massive. It just can't lose enough mass to become an object we might call a planet. Here's a table that describes the fates of various stars:

You mean, Lucas was lying to us about Tatooine?
Just so this post isn't completely "noise", I remembered a related post from some time ago.
Wow, I didn't know about that. Very cool indeed! There must be some very interesting dynamics that go into producing a stable hexagon of clouds!
I dare to say it's one of the most intriguing universe discoveries after blackholes!
After comming across that news i went to check the month date to see if it was already april 1 (i often loose track on what day of the month is...i guess all man do ) Half of me just couldn't believe that, first reaction was, 'this feels like a prank!...'.

Anyway, please correct me if I'm wrong here: I believe planets a couple of times bigger than Jupiter will have enough mass to ignite and turn into stars. I vaguely remember the term "critical mass" from school, and that critical point would be what limits the seize a planet can have. If it's bigger it will become a star.
If I remember correctly, the range of masses, and thus object type, goes as follows:
Gas giant planet - less than 1% solar mass (Jupiter is 0.1% the mass of the Sun)
Brown dwarf - 1% to 8% solar mass
Red dwarf - 8% solar mass upwards
I do recall that the boundary between gas giant and brown dwarf, in terms of required mass, is somewhat fuzzy as I think there is evidence that not all brown dwarf examples have demonstrated deuterium fusion.

Sorry but: OMG!!!111 That's more lame than "Steven Wrong".
How the hell can a planet turn into a star? That's garbage physics. It makes no sense and I'm not even an expert on physics.
Nice vid, but where is Uranus?

I guess I have some reading to do.
I find it difficult to tell between speculation and facts in this thread.

Once the mass is big enough the preassure from it starts the nuclear fusion process - volià , a star is born!
No chance whatsoever. I'm as likely to turn into a rabbit as our planet is to turn into a star or black hole.
