Stargazers have witnessed a partial eclipse of the Moon on the 50th anniversary of the launch of the Apollo 11 rocket.
Spectators gathered around the world to witness the event, which lasted about an hour.
Most of the time the Moon passes above or below the Earth's shadow, so you don't see a lunar eclipse every month.
A partial eclipse occurs when the Earth casts a shadow over half the Moon, as the Sun, Earth and Moon align in what astronomers call a "syzygy".
Australian National University astronomer Brad Tucker says partial eclipses "actually are quite rare" and there will not be another one for about two years.
"So really the next lunar eclipse of any kind is in 2021. We'll get a couple of partials and a total, but 2020 is going to be kind of a boring year," he said.
It came as US space agency NASA marked a half century since the Apollo 11 spaceflight mission was launched — on July 16, 1969 — from the Kennedy Space Centre in Florida.
US astronaut Michael Collins, who remained in lunar orbit while Buzz Aldrin and Neil Armstrong landed for their famous Moon walk, spent the golden anniversary at Kennedy Space Centre's Launch Complex 39A in Florida.
At NASA's invitation, Mr Collins marked the precise moment — 9:32am on July 16, 1969 — the Apollo 11 rocket departed for humanity's first Moon landing.
