WATCH: Partial lunar eclipse enjoyed by stargazers
The partial eclipse was visible in parts of Ireland and as far afield as Australia, Africa and much of Asia.
The partial lunar eclipse was witnessed across the world on Tuesday evening.
A lunar eclipse occurs when the Earth, sun, and moon are almost exactly in line and the moon is on the opposite side of the Earth from the sun.
The moon is full, moves into the shadow of the Earth and dims dramatically but usually remains visible, lit by sunlight that passes through the Earth's atmosphere.
People shared their pictures and video on social media and also celebrated the fact it came 50 years to the day after Neil Armstrong, Buzz Aldrin and Michael Collins blasted off into space for a mission like no other on July 16, 1969.
One Twitter user said: "Watching a partial lunar eclipse on 50th anniversary of Apollo 11 launch is really quite magical."
Another wrote: "So 50 years since the best achievement for spacefaring that man has achieved thus far, Apollo 11's launch 50 years today, is celebrated with a partial lunar eclipse. Just brilliant. Absolutely fantastic."
The 1969 mission marked one of humanity's biggest moments in space exploration.
A few days after the launch, on July 21, people across the globe watched in amazement as Armstrong and Aldrin walked across the lunar surface, taking photos, collecting samples, planting a US flag and taking a call from then-president Richard Nixon.
