What appeared to be a sizzling fire poured over Yosemite’s iconic El Capitan rockface this year. But it wasn’t hot nor was it a flame. Rather, this so-called firefall happens when the winter light hits the melting snow just as the sun is setting. The fiery display occurs at the same time every year.

In that same photo contest, photographer Songda Cai collected a Commended award in the Behavior category this year. Her snazzy photo illuminates a jellyfish carrying a type of deep-sea octopus called an argonaut — males rely on jellyfish for protection from predators.

In a study out this year, researchers equipped with computer models looked at climate changes during the Quaternary period, which started around 2.59 million years ago and continues into today. They found that Earth has not undergone any such changes as rapid as those seen today. During the Quaternary, glaciers would have crept down from Greenland (shown here) to cover much of North America and northern Europe.

China’s “blue tears” are not streaming from people’s eyes, but rather created by a bloom of toxic bioluminescent creatures called dinoflagellates. And their toxic “tears,” which create a beautiful glow in the waters of the East China Sea, are growing bigger every year, researchers found.

A new documentary reveals the behind-the-scenes story of an oddball sky glow endearingly named “Steve” that was first spotted over Canada in 2016 — to the delight of aurora chasers and skywatchers alike. Steve resembled typical aurora in some ways, but its ribbons and ladders of purple and green light were shaped differently than those of other aurora. The documentary, “Chasing Steve,” is currently available to view in Canada on Vimeo, and it will soon be available to rent or purchase in the U.S. via the film’s website.

The eruption of the Russian volcano Raikoke in June painted sunrises and sunsets the world over in a purple hue. Here’s how: The eruption spewed sulfur dioxide into the atmosphere, leading to tiny particles called aerosols. These aerosols scatter sunlight, generating more purples at sunrise and sunset. The image above shows one such purple sunrise above Lake Isabelle in Indian Peaks Wilderness, Colorado.

NASA’s Earth Observatory shared a haunting image this year showing the blazing heart of a fire cloud hovering above Earth. The magnificent image was snapped on Aug. 8 in eastern Washington state. Though surreal-looking, these fire clouds — also called pyrocumulonimbus or PyroCb clouds — can be quite disruptive, as they act like chimneys to funnel smoke and particles from wildfires into the lower stratosphere.

In this award-winning photo by Alexander Stepanenko, a majestic, bird-shaped aurora spreads its wings over a destroyed military hydroelectric station outside of Murmansk, Russia. This image and other spectacular skyscape beauties were shortlisted this year for the Astronomy Photographer of the Year contest, organized by the Royal Observatory, Greenwich in the United Kingdom.
