Two shades beyond Neptune
Article Abstract:
Astronomers have suggested that bodies, known as Kuiper-belt objects (KBO), orbiting in the outer Solar System have two colour bands. One group has neutral colours and the other is red. Colour may be linked to size. Developments in spectrophotometry have enables scientists to measure the different colours of the bodies. The colours are the result of differences in mineralogical make-up. The bodies look grey to the human eye.

Light through a gravitational lens
Article Abstract:
A planet with a mass lower than that of Neptune was detected by a lensing technique after its gravity bent the light from a remote star. Microlensing, along with other planet-finding techniques, plays an important part in gathering a complete picture of planet statistics right down to the regime of rocky planets and it can used in spotting planets outside the Solar System.
