Every time we run one of these tournaments, we are surprised by what catches the eyes of our readers. It is time to surprise us again. Cast your votes now in round three to pick the best four of the Earthly 8. Voting ends on April 13 at 9 a.m. U.S. Eastern Time. Check out the remaining competitors below.
“Past Winners” Bracket: Ocean Sand, Bahamas (#5) vs. A View of Earth from Saturn (#2)
Fire in the Sky and On the Ground has pulled off two massive upsets. In round 1, it beat #2 seed Night Light Maps Open Up New Applications, 71 to 29 percent. In round 2, Fire beat the sentimental favorite and oldest image in Tournament Earth, All of You on the Good Earth — the original Blue Marble photo (1968) and the inspiration for the first Earth Day (1970). The voters chose the auroral fire over Apollo 8 fame by 57 to 43 percent.
“Ice and Land” Bracket: Where the Dunes End (#8) vs. Retreat of the Columbia Glacier (#6)
Since its launch on the web in April 1999, NASA Earth Observatory has published more than 15,500 image-driven stories about our planet. In celebration of our 20th anniversary — as well as the 50th anniversary of Earth Day — we want you to help us choose our all-time best image.
For now, we need you to help us brainstorm: what images or stories would you nominate as the best in the Earth Observatory collection? Do you go for the most beautiful and iconic view of our home? the most newsworthy? the most scientifically important? the most inspiring?
Search our site and then post the URLs of your favorite Earth images in the comments section below. Please send your ideas by March 17.
In late March 2020, we will include some of your selections in Tournament Earth, a head-to-head contest to vote for the best of the best from our archives. Each week, readers will pick from pairs of images as we narrow down the field from 32 nominees to one champion.
The all-time best Earth Observatory image will be announced on April 29, 2020, the end of our anniversary year.
If you want some inspiration as you begin your search, take a look at the galleries listed below. Or use our search tool (top left) to find your favorite places, images, and events.
NASA’s Worldview app lets you explore Earth as it looks right now or as it looked almost 20 years ago. See a view you like? Take a snapshot and share your map with a friend or colleague. Want to track the spread of a wildfire? You can even create an animated GIF to see change over time.
Through an easy-to-use map interface, you can watch tropical storms developing over the Pacific Ocean; track the movement of icebergs after they calve from glaciers and ice shelves; and see wildfires spread and grow as they burn vegetation in their path. Pan and zoom to your region of the world to see not only what it looks like today, but to investigate changes over time. Worldview’s nighttime lights layers provide a truly unique perspective of our planet.
What else can you do with Worldview? Add imagery by discipline, natural hazard, or key word to learn more about what’s happening on this dynamic planet. View Earth’s frozen regions with the Arctic and Antarctic views. Take a look at current natural events like tropical storms, volcanic eruptions, wildfires, and icebergs at the touch of a button using the “events” tab.
By removing natural and stray light sources, researchers have provided a clearer picture of the human footprint on Earth. Learn more about this image. (NASA Earth Observatory image by Joshua Stevens, using Suomi NPP VIIRS data from Miguel Román, NASA GSFC.)

Some of the environmental challenges we face are daunting and can seem intractable, but there are some good reasons to feel reassured by the tools and expertise that the scientific community brings to the table. Americans live in a country where the number of deaths due to hurricanes, landslides, floods, droughts, tornadoes, blizzards, and other weather hazards have plummeted over the past century, and that is largely due to better understanding and to appropriate hazards warning systems that Earth scientists have developed.
Computers and instruments that used to take up whole rooms now fit snugly onto autonomous aircraft, satellites, and robots. At this moment, 1,459 satellites orbit Earth—including 19 that are part of the NASA fleet keeping a watchful eye on this dynamic, fragile planet. The authors of the EOS article note that a unified, global, high-resolution 3-D map of the human fingerprint on Earth is within reach due to the remarkable lidar instruments, aerial photogrammetry, and satellite observations that are now available.

To get a sense of the sophistication and breadth of the information satellites now collect, just navigate to your home town with NASA’s Worldview browser or take a look at the Earth Observations (NEO) data archive. You will find information on everything from plant health to particulate aerosol levels to fires to city lights.
As you look, keep in mind that NASA isn’t just collecting that data for data’s sake. The Applied Sciences program is focused on making that data useful to citizens, resource managers, and civic planners in ways that make life better here on Earth. So if you plan to celebrate Earth Day by cleaning up trash in your neighborhood or adopting a piece of the planet with NASA, rest assured that you are not alone in working to make the planet just a little bit more livable.
