The mystery object seen moving through our Solar system shows the void between the stars is far from empty. So can we expect more interstellar visitors?
Researchers are looking at whether devastating asteroid strikes are predictable or random.
Patience can be rewarded as with this composite of the 2016 Geminids meteor shower, seen over Mt Teide volcano on the Canary Islands, off Spain.
2017 is looking to be a spectacular year for meteor showers. So here's what to look out for in both the northern and southern skies.
