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.
The Black Marble
“Nothing tells us more about the spread of humans across the Earth than city lights,” asserts Chris Elvidge, a NOAA scientist who has studied them for 20 years.
The View from the Top
Ocean scientist Norman Kuring of NASA’s Goddard Space Flight Centre pieced together this composite image of Europe, Asia, North Africa, and the entire Arctic.
Flying Through a Crack in the Ice
The above image is a still frame captured from a three-dimensional, virtual flight through the new rift in the Pine Island Glacier.
Nasa explains: “Red sprites” are short-lived, red flashes that occur about 80 kilometers (50 miles) up in the atmosphere. With long, vertical tendrils like a jellyfish, these electrical discharges can extend 20 to 30 kilometers up into the atmosphere and are connected to thunderstorms and lightning.
The entire length of Baja California and the Pacific coast of Mexico.
Auroras over North America
Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun stirred up the magnetic field around Earth and produced gorgeous displays of northern lights.

A Changed Coastline in Jersey
The aftermath of Hurricane Sandy
New Volcanic Island in the Red Sea
A new island is forming in the Red Sea. About 60 kilometers (40 miles) from the coast of Yemen, an undersea eruption began in mid-December 2011.
El Hierro Submarine Volcano Eruption
Four months after it began, the underwater volcanic eruption off El Hierro Island persists. This natural-color satellite image, collected on February 10, 2012, shows the site of the eruption, near the fishing village of La Restinga.
On October 29, 2012, Hurricane Sandy approached the densely populated U.S. East Coast.
City Lights of the United States 2012
This image of the United States of America at night is a composite assembled from data acquired by the Suomi NPP satellite
