In this Sunday, August 5, 2012 file photo South Africa's Oscar Pistorius starts in the men's semi-finals of the 400-meter in the Olympic Stadium at the 2012 Summer Olympics, London. Pistorius could be granted parole on Friday, Nov. 24, 2023 after nearly 10 years in prison for killing his girlfriend. The double-amputee Olympic runner was convicted of a charge comparable to third-degree murder for shooting Reeva Steenkamp in his home in 2013. He has been in prison since late 2014.

The view “looks” northward over Sicily and the “boot” of Italy, with the Mediterranean Sea representing most of the visible water in the view and the Adriatic Sea to the right of center. Tunisia is partially visible at left. Part of a docked Russian spacecraft and other components of the ISS are in the foreground. (Photo by AP Photo/NASA)

“I'm Josh Fancher, a 21 year old with an avid interest in photography, including macro, nature and wildlife, night photography, landscapes, cityscapes and architectural photography. Inspired by the beautiful and amazing water drop photography of Martin Waugh, I started doing water drop collisions in December of 2007. I use a 105mm Micro Nikkor lens for water drops, along with a pair of Nikon SB 600 flashes. I recently got a StopShot system (Nov 2009), which makes timing a lot easier. Before then, timing was manual, with an eye dropper, eye-hand coordination, and a lot of patience” – Josh Fancher. (Photo by Josh Fancher)

A swimmer stops short of a red algae bloom at Sydney's Clovelly Beach on November 27, 2012, which closed some beaches for swimming including Bondi Beach for a period of time. While the red algae, known as Noctiluca scintillans or sea sparkle, has no toxic effects, people are still advised to avoid swimming in areas with discoloured water because the algae, which can be high in ammonia, can cause skin irritation.

More than 400 people stripped off and ran into freezing waters to celebrate the autumn equinox – and raise money for charity at Druridge Bay, Britain, September 25, 2016. It was the largest turnout the North East Skinny Dip has ever seen in its five-year history, and it was also the first time it has ever rained on the morning of the event. Revellers gathered from 5.30am on Sunday at Druridge Bay, in Northumberland, before baring all in the North Sea. (Photo by David Charlton Photography)

In this photo taken in October 1917, provided by Russian State Documentary Film and Photo Archive, a machine gunner looks through a window at his position near the Kremlin in Moscow, Russia. The 1917 Bolshevik Revolution was long before the digital revolution allowed anyone to instantly document events. But the clumsy cameras of the time still caught some images that capture the period's drama. (Photo by Russian State Documentary Film and Photo Archive via AP Photo)
