On Wednesday this week, 26 May, we're heading outside to spot a cosmic coincidence in the evening sky - a lunar eclipse.

This week, we're getting up before dawn to try catching a glimpse of the Eta Aquarid meteor shower. It's a cosmic lightshow that only comes around once a year, as fragments of Halley's comet streak through our atmosphere. It's at its peak between the 5th and 7th of May, visible from 2am until sunrise at around 6am.
