4 April 2007: Astronomers have serendipitously discovered a record-breaking pair of low-mass objects with an extreme orbital separation. The petite objects, each of which has a mass less than 100 times that of Jupiter and could be either stars or brown dwarfs, are separated by more than 5,000 times the distance between the Sun and Earth – a value that breaks the previous record by a factor of three and leaves the duration of their future together uncertain.

8 January 2007: Astronomers have announced the discovery of huge quantities of an unusual variety of oxygen in two very rare types of stars. The finding suggests that the origin of these oddball stars may lie in the physics behind the mergers of white dwarf star pairs.
