A spectacular (and very rare) ice halo photographed (on an iPhone) by Michael Schneider this month in the Swiss Alps. According to Schneider, the phenomenon developed gradually as fog dissipated at the top of a ski resort.

The annotated overlay (using information from this site on atmospheric optics) was created by Mark McCaughrean.

A short film by cinematographer Chris Bryan, who worked on BBC’s ‘Blue Planet II’, showing the mesmerising crash and surge of ocean waves in slow motion. Sez he:

I love filming in the ocean more than anything, its not just a job, its a passion. And sometimes its nice just to document waves without surfers riding them. The feeling of jumping off the rocks in the dark by myself just to capture the very first rays of light hitting the ocean without another sole in sight is unexplainable, its one of the most amazing feelings ever, its like my own personal therapy.

Behold: a very unusual form of large-scale electrical discharge known as red sprite – never before photographed at this level of detail. To wit:

Even though sprites have been recorded for over 30 years, their root cause remains unknown. Some thunderstorms have them, but most don’t. These mysterious bursts of light in the upper atmosphere momentarily resemble gigantic jellyfish. A few years ago high speed videos were taken detailing how red sprites actually develop. The featured image was captured last month in high definition from Italy. One unusual feature of sprites is that they are relatively cold — they operate more like long fluorescent light tubes than hot compact light bulbs. In general, red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side.
