Houston, we have a poll.
An elusive red 'sprite' photographed high in the night sky by the International Space Station will face off against a view of New Jersey's devastated coastline, a 'Black Marble' photo of the night sky and solar flares in Nasa's vote for the best image of Earth taken last year.
In all 32 images will battle for the title of Earth image of the year, awarded by the Nasa Earth Observatory.
They've been paired off for knockout-style votes, with two pictures eventually meeting in a final poll to find 2012's winner.
The images range from dramatic landscapes to amazing new uses of scientific data.
Voting is open now at Nasa's website - here are a selection of our favourite images from the poll.
