Of course it could be either 2011 HD63 OR 2008 EK1

get a telescope and jupiter looks amazing some massive craters visible if you can keep up with it, orbits really fast

Hi those are not craters you can see on Jupiter as it's a huge gas ball, they are actually huge storms that have been raging for thousands or millions of years, should be able to make out the dark bands with a telescope too

so what about all ther big asteroids that have collided with this planet??? they must leave some kind of remnants???

It's a gas giant mate, there wouldn't be any collision (as such) but I'm guessing the smaller particles could be caught in it's orbit & are possibly responsible for the dark reddish bands but there are no craters as there would be no impact of the kind where an asteroid hit a giant solid mass to leave one.
Google it, those big dark circles on Jupiter are giant storms & they even move to different parts of the planet & vary from time to time in their power, size & visibility

Heard on talk sport there's a star that went supernova 25million light years ago and the lights just reaching us, by the big dipper apparently but couldn't see because of clouds

Most of the stars you can see are at least 25 million light years away, that means even if you could travel at the speed of light it would still take 25 million years to get there & yes these events have already happened & it's took that long for it to become visible from earth, hope I'm not teaching you to suck eggs lol & I am by no means any sort of expert AT ALL (just to be clear)

Just to confirm what others have said, Jupiter is one of the gas giants. The inner planets, those closer to the sun, i.e. Mercury, Mars, Venus and The Earth are all solid planets (although Venus does have a curtain of nasty gas surrounding it). The outer planets, Saturn, Jupiter, Uranus and Neptune are the "Gas Giants". The laws of physics determine that they have to be. The asteroids/meteorites that crash into Jupiter, e.g. Shoemaker Levy 9 in 1996 (I think), don't leave craters but they do leave scars in the upper parts of the clouds/storms for a while. I think the SL9 scars were visible for several weeks.

Incidentally, the "Great Red Spot" of Jupiter, which is a huge storm that varies in size from time to time, but has lasted for many centuries, is so large in itself that the Earth could fit inside it.
