Giant extra-galactic planet discovered

I wonder what life would be like on planets in other galaxies?

I wonder what life would be like on planets in other galaxies? Probably much like life on planets in this galaxy. I love how finding a new planet is almost commonplace now.

Makes me wonder how typical it is to have some random star floating around with a planetary system in tow out in intergalactic space. What a weird place that would be to live in.

That's not what happened. It was always part of a galaxy, just not ours. It was part of a dwarf galaxy that merged into the milky way, so it was never really in intergalactic space.

It was part of a dwarf galaxy that merged into the milky way, so it was never really in intergalactic space. this is true. but i have two questions. 1 did this star actually form before or after the two galaxies merged, if after than it should probable called a local star. 2 do the stars of this dwarf galaxy still more or less orbit the center of that galaxy as it orbits ours.

I think you have answered your own question. The fact that the star this planet orbits is called extragalactic star and not local is a bit of a clue, besides how could it have formed in a dwarf galaxy AFTER it had merged with the milky way, by definition the dwarf galaxy ceased to be a separate entity once the two objects merged. 2 do the stars of this dwarf galaxy still more or less orbit the center of that galaxy as it orbits our...

They would have done whilst the dwarf galaxy was separate. Now that the dwarf galaxy has merged into the milky way it no longer exists and so stars can not orbit it's centre. HIP 13044 does, however, orbit the milky way in an unusual way. It is part of the Helmi strea... [More]

Random thought, Why can't we ever give planets a COOL name? I mean, "HIB 13044"? Bor-ing. I vote we rename it "Jose" or "Alberto" something ethnic. After all, it IS an immigrant! *wink* Hey, someone check that planets papers!

After all, it IS an immigrant! *wink* Hey, someone check that planets papers! planets and stars were given numbers so as they could be catalouged for knowing what part of the galaxy or universe (exoplanets) they reside in, however some are named and most are named after the mythical gods,
