A line of trees are dwarfed by the undulating hills of the Moravian Fields in the Czech Republic. “I love how the land surrounding the trees looks like a painting,” writes @natgeoyourshot Community Manager Christina Shorter (@shortercr). “What a beautiful blend of colors.” This photo was selected for the March 14, 2017 Daily Dozen.
Top Shot features the photo with the most votes from the previous day’s Daily Dozen, 12 photos chosen by the Your Shot editors from thousands of recent uploads. Our community votes for their favorite photo from the selection, and the Top Shot is showcased on the @natgeoyourshot Instagram account.
Looking for planets outside our solar system, also known as exoplanets, just got a little more complicated. Scientists typically search for patterns like rings, arcs and spirals in disks of dust and gas around young stars because those patterns are often considered a sign that an unseen planet orbits a star. But this new simulation shows that planets aren’t the only explanation — the dust and gas in the disk can interact to make those patterns, too.
The light from the star strips the dust of electrons, which heats up the gas, which traps more dust, creating a cycle. Lumps of dust grow into spirals, rings and arcs. No planets necessary. Of course, planets could still be the cause, but the new study cautions against jumping to conclusions!

After 17 years with National Geographic, wildlife conservation photographer and cinematographer Paul Nicklen (@paulnicklen) felt compelled to start something new. “I wanted to see immediate impact through photography,” explains Paul, who co-founded SeaLegacy (@sea_legacy), a collective of visual storytellers who document the biggest issues facing our oceans today. “My goal is to use my camera to connect people to the species of animals that need our help.”
On #WildlifeConservationDay, Paul offers this message: “I want people to understand that animals are all part of a complex ecosystem. You cannot dismiss an insect while pouring your love and attention into panda bears and baby white harp seals. We need to realize that entire ecosystems are connected, from the very top to the very bottom.”
Starting today, when people search for a hashtag associated with harmful behavior to animals or the environment, they will see a content advisory screen. We are committed to fostering a safer, kinder world both on Instagram and beyond.
