Does the colliding gas have a chemical reaction forming oxygen particles or is it something else. please answer, Im intruigued. Thanks. How is this fire created with out oxygen in space.

please answer, Im intruigued.

Thanks.

The fireballs might well sterilize nearby worlds -- the question is, how near is "nearby"? When Andromedia ultimately collides with the Milky Way in a few million years, that sort of display probably wouldn't happen, as the masses involved are nothing compared to that of the Coma cluster, which drives the display in the above photographs. But when galactic clusters collide, the energies released are tremendous -- as witness previous articles on Universe Today about such collisions -- and the results might well include plenty of sterilized or obliterated stellar systems.
