Supernova
The explosion (a supernova) produces a glowing cloud of gas (called a nebula) that slowly expands and dissipates (eg the crab nebula).
The five outer planets are the ones with bigger orbits than the Earth, which are Mars and the four giant planets. The outer planets can be seen at their brightest at midnight, when they are at opposition. That never happens for the inner planets Mercury and Venus.
Gases
Its blown into interstellar space - to enrich and mix with the gasses already out there.

A supernova happens when a massive star collapses in on it's self and explodes. Eventually a star stops being able to fuse new elements and gravity can no longer hold it together. When a star reaches this point, if its mass is large enough, the outer layers will be ejected in a violent supernova explosion.
The Sun will not explode [See related question], the Sun will just expand into a red giant and then after expending it's outer layers become a white dwarf.
A star that explodes is called a supernova.

It is a supergiant.(the late stage in the life cycle of a massive starin which the core heats up, heavy elements formedby fusion, and expands; it can eventually explodeto what scientist call a supernova.)-Missy K
Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
