Check this out... it's one of thousands of drawings of unidentified flying objects (UFOs) spotted by members of the public. This one was seen in Woolwich.
They're part of more than 8,500 pages of reports describing people's strange sightings and eerie experiences with extra-terrestrial activity.
The reports have been released by the Ministry of Defence and given to the National Archive so we can all see them for free.
This picture of a spaceship creating crop circles was also included in the reports, which mentioned the issue of UFOs being debated in the House of Lords in 1979.
This doughnut-shaped pink blob was caught on camera by a retired RAF officer in March 2004. He sent it to his old bosses who had the job of investigating UFOs.
Is it a bag? Is it a rock? Nope - the person who drew this said the dots represented the lights they saw on the bottom of a spaceship!
