Reported by the sailors at least since the 19th century, a rogue wave is a very large, extremely steep, unexpected and suddenly appearing surface wave. It is also called as a freak wave, monster wave, killer wave, and extreme wave.
For centuries, seamen told stories about encounters with extremely big, ship-sinking waves, much bigger than any wave surrounding them. According to sailors, these waves were also so steep – almost vertical, insurmountable walls of water.

It’s an oldie but goldie: International Space Station Expedition 27 and 28 astronaut Ron Garan presents a video about his return from space, including a compilation of time-lapse photography of “our fragile oasis”, the Earth. The images were captured by Garan and Expedition 28 and 29 astronaut Mike Fossum while aboard the space station.

Before going silent due to a huge dust storm on June 10, 2018, NASA’s Mars Exploration Rover Opportunity documented an amazing 360-degree panorama from multiple images taken at what would become its final resting spot in Perseverance Valley. The Mars rover collected these images over the course of 29 days.

On December 18, 2018, at around noon local time, a meteor about 10 meters (30 feet) long and weighing more than 1,500 tons, plunged into Earth’s atmosphere. It exploded over the Bering Sea and released energy equivalent to 173 kilotons of TNT – at least ten times more powerful than “Little Boy, the atomic bomb dropped on the Japanese city of Hiroshima on August 6, 1945. Japanese weather satellite Himawari 8 has recorded the fireball of the meteor before it exploded.

The blue whale (scientific name: Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). Up to 31 meters (102 feet) in length and 190 tonnes (210 short tons) in weight, it is the largest extant animal and also is the heaviest known to have existed. But it’s hard to conceptualize how big these wonderful animals really are. To put things into perspective, Facts in Motion channel prepared a video titled “Blue Whales Are Way Bigger Than You Think”. The video also explains the evolutionary reasons behind how and why blue whales get that large.
