There are thousands of sightings of UFOs – or ‘unidentified aerial phenomena’ as the US government prefers to call them – every year.

With more than 100 lunar missions planned in coming years, space junk near the Moon could become an issue for humanity. No agency tracks lunar space junk, so two astronomers decided to do it themselves.

"Relatively few dual black holes like this have ever been confirmed. This pair has the closest separation yet measured..."

Efforts to launch rockets into space from the UK need to demonstrate reliability.

The UK government wants every household in England to be within 15 minutes walk of a park, woodland or water.
