There aren't many features on symbols for power and eroticismEarth that look bad from space.

Mountains? Pretty great. Deserts? Freaking gorgeous. How about clouds? Awesome! And don't even get me started about the Bahamas.

But perhaps one of the most beautiful features of our planet as seen from space is actually created by some of the smallest organisms on our world.

While this photo may look gorgeous, it actually depicts one of the worst toxic algal blooms to hit Lake Erie in years.

The bloom image was taken by the Landsat-5 satellite in October 2011.

"Microcystis aeruginosa produces a liver toxin, microcystin, that commonly kills dogs swimming in infected water and causes skin irritation for people," NASA said in a statement.

This photo of a 2011 bloom in the lake show off those swirls of green in an amazing way, revealing just how widespread a bloom can be.

These blooms don't always become toxic, but given the right conditions, the algae can almost seem to overtake the lake, making it dangerous for fish and even potentially contaminating drinking water.

The European Space Agency's Sentinel-2A spacecraft caught sight of this swirling algal bloom (above) in the Baltic Sea in 2015.

A black streak moving from the top of the photo to the middle is actually the wake of a boat that can be seen toward the center of the vortex of the bloom.

In 2015, this seemingly safe bloom of algae off the coast of New York appeared in the Atlantic Ocean.

"The bloom was likely caused by coastal upwelling, according to Oscar Schofield, a marine scientist at Rutgers University," NASA Earth Observatory said in a statement.

"Upwelling is a process by which winds blow surface waters away from the coast, causing deeper, cooler, and often nutrient-rich waters to well up from the depths to fill the gap."

NASA’s Aqua satellite snapped this photo of an turquoise algal bloom swirling in the Black Sea on May 29, 2017.

While it can be harmful in too much abundance, algae is a key part of the ecosystems in the Black Sea.

"Here, ample water flow from rivers like the Danube and Dnieper carries nutrients to the Black Sea," NASA said in a statement. "In general, phytoplankton support fish, shellfish, and other marine organisms."
