Son doong cave is a cave in Phong Nha-Kẻ Bàng National Park, Bố Trạch district, Quảng Bình Province, Vietnam. Currently the biggest known cave in the world, the cave is located near the Laos-Vietnam border. Inside is a large, fast-flowing underground river.
In early August 2013, the first tourist group explored the cave on a guided tour at a cost of US$3,000 each. The group had six members from Australia, Norway, Russia and USA and spent 7 days and 6 nights for the tour. Next exploration trips will be arranged.

The International Space Station (ISS) moving in front of the sun in November 2020 by astrophotographer Andrew McCarthy. These incredible photos capture the clearest images ever taken of the International Space Station (ISS) moving in front of both the moon and the sun. The photos, taken within days of one another, were captured in the space of less than a second, as the space station could be clearly seen zooming across against the bright backdrops of both moon and sun. Photographer Andrew McCarthy, from California, USA, said the photo of the ISS in front of the sun, in broad daylight, was “one of my trickiest shots ever”.

Shemika Charles limbos under her car at Niagara Falls State Park on May 28, 2015 in Buffalo, New York. A world record holding limbo queen thinks she has become the first person to shimmy under a car. Shemika Charles amazed herself and onlookers when she bent over backwards to get underneath the SUV earlier this week. The supple 22-year-old entered the record books in 2010 when she limboed down to an incredible eight and a half inches – the height of a beer bottle. She trains for up to four hours a day to keep her body in peak condition and now travels around America performing with her family. However, regular performances put an incredible strain on her body and she sees a chiropractor once a week to have her hips realigned. Her mother was also a successful limbo dancer in her home country of Trinidad and Tobago but had to give up due to injury. (Photo by Ruaridh Connellan/Barcroft USA)
