They say that Jupiter does not have a rocky core and the planet is made up of entirely gas materials... If one was to send a missile/or a blowtorch and lit jupiter, will the entire planet ignite like a star?

I recieved this e.mail today is this really going to happen.
The Red Planet is about to be spectacular!

This month and next, Earth is catching up with Mars in an encounter that will culminate in the closest approach between the two planets in recorded history. The next time Mars may come this close is in 2287. Due to the way Jupiter's gravity tugs on
Mars and perturbs its orbit, astronomers can only be certain that Mars has not come this close to Earth in the Last 5,000 years, but it may be as long as 60,000 years before it happens again.

The encounter will culminate on August 27th when
Mars comes to within 34,649,589 miles of Earth and
will be (next to the moon) the brightest object in
the night sky. It will attain a magnitude of -2.9
and will appear 25.11 arc seconds wide. At a modest
75-power magnification

Mars will look as large as the full moon to the naked eye.
Mars will be easy to spot. At the beginning of August it will rise in the east at 10p.m.

the question was about things ive been seeing when i shut my eyes at night, i know im not mad because mad people never question if they are mad, also im not scared of these things, its like short frames of film with a singular image, oh and im also a sceptic when it comes to physchic abilities, but i would like anyone to contact me and let me know what they think! the things i see are as clear as day and as the days go by the images are becoming clearer and more frequent, imagine a tv with really bad reception that eventually tunes itself in, thats how it started it was like walking down one of those tunnels that are constantly turning and now theres none of that, i just relax for a minute or so and "click" an image starts to appear!
