Astronomers have long suspected such [b]rogue[/b]planets existed, but this is the first evidence, and the Japanese team believe there could be as many out there as there are stars, a finding likely to shock many.[/p][p=30, 2, left]How they [b]came into being[/b] is unclear. One theory is that they may be [b]cast-outs[/b], forgotten worlds [b]ejected from [/b]infant solar systems by[b]gravitational forces[/b] or [b]interplanetary collisions[/b].[/p]
[p=30, 2, left][b]Strictly speaking[/b], the objects aren't even planets, as by definition planets orbit a star or [b]the remains of[/b] one. But should the researchers have their calculations right, then strange dark [b]orbs[/b]which look very much like planets are out there, far far from any shining star.[/p][/font] How mysterious the universe is !
