Now this, of course, is hardly possible, but in the early stages of the formation of the solar system, Jupiter and Saturn could well have collided. According to calculations, collisions of giant planets in our Galaxy during the formation of planetary systems are quite frequent and can reach up to 1 per year.
The consequences of a hypothetical collision of our giant planets depend on their relative velocities, impact parameters and angular momenta.
If we consider precisely the head-on collision of Jupiter with Saturn (so that it comes down to the collision of nuclei), then there could be two scenarios, depending on their orbital velocities - either merging into one planet, or the complete destruction of both. Complete destruction could have occurred while both giants were in orbits with a radius of no more than 0.25 AU. (Such a close arrangement of exoplanets to a star is characteristic of hot Jupiters).
Being in high orbits (as now, for example) and having low relative velocities, giants merge in inelastic collisions. This happens:
Compression and collapse of the magnetospheres of the giant planets with the subsequent generation of radio bursts (recorded by telescopes).
Heating of the surface layers of planets up to 10,000 K (accompanied by flares in the UV and optical ranges), as well as partial loss of gas envelopes.
Ejection into space of a part of metallic hydrogen, followed by the formation of hydrogen clouds from it around the merged planets.
The hard silicate cores merge. (Fragments of solid rock from the cores of giant planets can be ejected only during collisions at high relative speeds (in low orbits with the complete destruction of planets) or after a supernova explosion.
