Some Americans got to see a full solar eclipse last summer.
That is when the moon crosses in front of the sun.
Photo bomb.
One photograph from the solar eclipse stood out.
The headline on CNET's website reads, International Space Station Photo Bombs 2017 Solar Eclipse.
A photo bomb is when someone or something unexpectedly enters a photograph as it is being taken.
When people photo bomb, they sneak or jump into a camera shot, usually as a joke.
Now you know what photo bomb means.
