Second Sun

When most interested in astronomy were reading ,talking and watching about the Pluto flyby of the New Horizons there appeared a small overlapped photo graph in various media showing Jupiter and a light emitting object. This was in relation to a similar solar system in deep space which had been located with a planet similar in size to the Jupiter but one that was glowing like the second sun in its solar system.
This is quite similar to a thesis our planet Jupiter is known about. It is widely believed that if our Jupiter were to amass a little more mass from its surrounding sky during the accreting process, in times of antiquity, then it would have started glowing like another sun( as a host of parameters would have combined) wherein the process of synthesising hydrogen and helium would have begun.
Having two sun’s to our solar system would have been interesting and the combinations of sunrises and sunsets and the amount of sunshine and darkness and the duration of bright and bleak and dark days and nights and their effect on seasons and evolution is going far too overboard and berserk.
