Earth from space — Incredible images of our planet from above

Earth from space This 2018 satellite photo of ice caps on the Arctic islands of Russia's Severnaya Zemlya archipelago highlights the beautiful concentric rings of color in the ice, which stand out against the islands' barren landscape.

Earth from space This 2017 satellite photo shows an unusual cloud "cyclone" nestled up against the coastline of Spain and Portugal. Researchers are unsure what caused the strange structure's spin, but ocean eddies and an extreme heat wave likely played key roles.

Earth from space This 2018 astronaut photo shows the rust-colored waters of Madagascar's Betsiboka River winding through a complex series of mangrove islands. Both the river and islands have been altered in recent years by destructive human practices.

Earth from space In 2018, satellite images captured a stunning spiral of cyanobacteria blooming in the Baltic Sea. The swirling mass of microbes helped to create a massive "dead zone" the size of West Virginia that starved the surrounding water of oxygen.

Earth from space In 2018, a weather satellite captured a massive thunderstorm cloud in the shape of a jellyfish. The bizarre cloud was the result of a meteorological phenomenon gone wrong.

Earth from space The massive caldera of Turkey's Mount Nemrut volcano is split in half, with one side made of solidified lava flows and the other half a deep crater lake. Covered in snow, the summit scene looks like the yin-yang symbol when viewed from above.

Earth from space A puzzling arc was spotted in the water of a Greenland fjord littered with iceberg fragments. There are a couple of possible explanations for this bizarre phenomenon but we will likely never know what caused it, experts say.

Earth from space A satellite image of the Galápagos Islands' La Cumbre volcano shows lava seeping from the iguana-covered mountain days into an ongoing, months-long eruption.

Earth from space Three closely grouped lakes in Ethiopia's Great Rift Valley have distinctly different hues thanks to a combination of unique features.
