After almost twenty years in space — thirteen of which were spent making extraordinary discoveries about the Saturn system, including its rings and natural satellites — NASA's Cassini spacecraft finally ran out of fuel. However, shortly before plunging into Saturn's atmosphere on September 15, 2017, the probe completed one final important mission: six close flybys of tiny moons located inside, or near, Saturn's rings....

Over the years, NASA has successfully deployed several rovers, landers, and orbiters to Mars. While the science laboratories continue to provide invaluable data about the Red Planet, their limited, or zero — as is the case with landers — mobility, restricts the space exploration vehicles to areas close to the original landing site. To obtain a more comprehensive view of Mars, the US Space Agency plans to send a fully-autonomous miniature test helicopter with the Mars 2020 rover, scheduled for launch in July 2020....

Termites are famous for their superior architectural skills. The mounds created by the industrious insects contain an elaborate network of tunnels with a series of chimneys that help regulate oxygen levels, temperature, and humidity to ensure the queen, who sits in a chamber underneath, is comfortable....

For pranksters and joke lovers, there is no better day than April 1. Often called April Fools' Day, it is the one day of the year when light-hearted tricks are not only expected but also welcomed by all. Some believe the fun holiday began in 1582 when the world transitioned from the Julian calendar, which celebrated the New Year on the last week of March, to the current Gregorian calendar. Those unaware of the change, or refusing to accept the January 1 start date, were often mocked and had jokes played on them on or around the old New Year. Others speculate the holiday began as a joyful way to welcome spring....

When a university intern stumbled upon a seven-foot fish washed up on the beach at the University of Santa Barbara's (UCSB) Coal Oil Point Reserve on February 19, 2019, scientists assumed it was the mola mola sunfish. One of the world's heaviest known bony fishes, the species, found in tropical and temperate waters around the globe, is common in the Santa Barbara Channel....

Need a reason to smile? Then you will be happy to know that today, March 20, 2019, is not just the first day of spring, but also the International Day of Happiness. Established by The United Nations (UN) in 2012, it is meant to remind us that happiness is an essential human goal and right. This year's theme, Happier Together, encourages people worldwide to focus on what we have in common, rather than what divides us....

What better way to welcome spring than by dousing yourself and your friends with vibrant colored powder? That is the essence of the popular Indian festival of Holi. Observed annually on the last full moon day of the Hindu lunar month, Phalguna, this year, the fun event will be celebrated on March 21, 2019....

In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's famous Sardine Run off the coast of Point Elizabeth. The annual migration of billions of Sardinops sagax, more commonly known as South African pilchards or sardines, is a big draw for predators, especially the Cape gannet, a beautiful, cream-colored seabird, and the common dolphin. The two species work together to herd the large group of fish and separate them into smaller shoals known as bait balls, which are then scooped up by not just the birds and the dolphins, but also other hunters such as copper sharks and Bryde's whales....

Carbon dioxide (CO2), released by activities like burning of fossil fuels such as coal, oil, and natural gas, is one of the biggest contributors to the greenhouse effect, responsible for global warming. Over the years, scientists have come up with several innovative solutions to capture the polluting gas. However, none have been practical enough to implement on a large scale. Now, researchers at RMIT University in Melbourne, Australia believe they may have finally found a feasible way to reduce atmospheric CO2 – turning the gas back into coal!...
