Chaos in cosmos: System of two stars with three planet-forming discs of gas

more »
A star with a ring of planets orbiting around it -- that is the picture we know from our own solar system and from many of the thousands of exoplanets observed in recent years. But now researchers have discovered a system consisting of two stars with three rotating planet-forming accretion discs around them. It is a binary star where each star has its own planet-forming disc and in addition, there is one large shared disc. All three planet-forming discs are misaligned in relation to one another.

Scientists have found that exposure to highly energetic charged particles -- much like those found in the galactic cosmic rays that will bombard astronauts during extended spaceflights -- causes significant long-term brain damage in test rodents, resulting in cognitive impairments and dementia.
