Plasma Universe

At ... the universe is highly magnetic - with everything from stars to planets to galaxies producing their own magnetic fields. The researchers created a hot turbulent plasma (quite small and short lived) in the laboratory - just the size of a penny. The looked at how the turbulence and its motions was able to amplify a weak magnetic field to the turbulence seen on our Sun. It is the first laboratory experiment of a theory explaining the magnetic fields of various cosmic bodies, the plasma working like a dynamo.

At ... NASAs New Horizons spacecraft is creating images of cosmic bodies beyond the furthest planet - in the so called Kuiper Belt. It also hopes to send back lots more images of the 2 dozen objects thought to be orbiting out there - and centaurs.

Meanwhile, Jovan sent in the link to ... about a year ago astronomers discovered seven earth sized planets around the star known as Trappist 1. They orbit extremely close to their home star - but apparently Trappist I is fairly cool in comparison with our own Sun. In spite of that some of them are thought to be in the habitable zone. The search is now on to discover is they might possess water - and other goodies required of life.
