The NICER telescope array aboard the International Space Station has made the most accurate measurements yet of a pulsar’s mass and size.

For the seventh and final time this year, the Moon occults outermost planet Neptune on Tuesday 6 December. Weather permitting, this event will be seen over a swathe of the Western Hemisphere including the northeastern USA, eastern Canada, Greenland, Iceland and the western British Isles.
