At … a space rock exploded into a ball of fire above the Bering Sea without anybody actually seeing or reporting it. Not many people live up that way of course – and it was out at sea. The surprisng point is that it was not immediately picked up by scientists. It was discovered on March 8th by a Canadian scientist looking at data used by the Test Ban Treaty Organisation (nuclear tests and big bangs in general). He noticed seismic sound waves from the explosion in the atmosphere and other scientists looked at weather data to see if it had been picked up – and it had. It was the most powerful explosion in the atmosphere since the Chelyabinsk meteor of 2013.

At… … was sent in by Gary. The largest metallic asteoid known to science could be covered in iron volcanoes it claims. The asteroid, known as Psyche 16, might be the innards of a planetary core, made largely of iron and nickel (as mainstream have diagnosed the core at the heart of the earth). It may also be covered in regolith debris that includes dust and soil as on the surface of the Moon). The asteroid is 130 miles wide and is located in the asteroid belt between Mars and Jupiter. Looks likely to be the target of a new mission.
