“We’ve never found another galaxy system like the Milky Way before, which is not surprising considering how hard they are to spot! It’s only recently become possible to do the type of analysis that lets us find similar groups,” said Dr Robotham, lead author of a paper, published in the Monthly Notices of the Royal Astronomical Society (arXiv.org version).

Well, well! I'm loving how much momentum we have picked up in exploring space. First we find plausible life-suitable planets, now we are finding galaxies that resemble the physical structure of our own.
Some would argue that everything in life is based around spirals and that perhaps the spiral is the foundation of which everything physical is manifested. Does that mean that these closely-resemblant galaxies could possibly be a suitable host for life? Who knows. I'd bet money on it.
Regardless, scientists say that there is only one billion years left for these galaxies. Not a long time in comparison to all the ancients in the Universe, but indeed a sufficient amount of time as far as human lives are concerned. Let's just hope we can afford a vacation ticket there before the one billion years is up!
(Image shows one of the two ‘exact matches’ to the Milky Way system found by the team. The larger galaxy, known as GAMA202627, which is similar to the Milky Way clearly has two large companions. Bluer colors indicate hotter, younger, stars like many of those that are found in our galaxy (Aaron Robotham / ICRAR / St Andrews / GAMA))
