A pair of strange new worlds that blur the boundaries between planets and stars have been discovered beyond our Solar System ...
The pair belongs to what some astronomers believe is a new class of planet-like objects floating through space; so-called planetary mass objects, or "planemos" (an unofficial term), which are not bound to stars ... they circle each other rather than orbiting a star.
"This is a truly remarkable pair of twins - each having only about 1% the mass of our Sun," said Ray Jayawardhana of the University of Toronto, co-author of the Science paper ... "We are resisting the temptation to call it a 'double planet' because this pair probably didn't form the way that planets in our Solar System did," said co-researcher Valentin Ivanov of the European Southern Observatory (ESO) in Santiago, Chile ...
They ... can be found in the Ophiuchus star-forming region some 400 light years away. They go under the official name Oph 162225-240515, or Oph 1622 for short.
Professor Jayawardhana, who also worked on the study, added: "The diversity of worlds out there is truly remarkable. Nature often seems more prolific than our imagination."
Nasa's new infra-red telescope — now named the Spitzer Telescope — can see through clouds of dust that visible light can't penetrate
