Remains Of Four-Legged Whale That Walked On Land Found in Peru

Researchers have long known that the ancestors of the mighty whales were nimble, four-legged creatures that were comfortable both on land and in the sea. However, given that the only evidence of the early mammals had been found in present-day Pakistan, India, and parts of Africa, scientists were unsure of how the mammals had dispersed to the Western Hemisphere. Now, thanks to the aptly-named Peregocetus pacificus (P.pacificus), or "traveling whale that reached the Pacific," paleontologists finally have an answer to this all-important migration mystery.

The First-Ever Image Of A Black Hole Is Stunning

The existence of black holes, first proposed  by Albert Einstein in his 1916 general theory of relativity, has been known for decades. However, astrophysicists have thus far relied on indirect evidence, such as  the stars orbiting a large and invisible object in the center of the Milky Way galaxy,  to prove their presence. That changed on April 10, 2019, with the release of the first-ever direct visual evidence of a black hole in the center of the galaxy M87, located 55 million light-years from Earth.

The Mystery Of Saturn's Ravioli-Shaped Moons Has Finally Been Solved

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 on September 15, 2017, the probe completed one final important mission: six close flybys of tiny moons located inside, or near, Saturn's rings. 

Trash-Eating "Sharks" Are Taking Over Harbors Worldwide

While even the mention of a shark swimming close to shore is enough to send residents scurrying for cover, the "WasteShark" is being welcomed with open arms. The brainchild of South African entrepreneur Richard Hardiman, the aquatic drone is designed to devour all floating debris, including plastic and other non-biodegradable trash, that has accumulated along coastal waters, before it drifts out to sea.

NASA Plans To Send A Helicopter To Mars In 2020

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.   

Ancient Network Of Massive Termite Mounds In Brazil Are "Biological Wonders"

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.  

Diet Drugs Seem To Make Mosquitoes Less Thirsty For Human Blood

Female mosquitoes, which feed on human blood to obtain iron and amino acids required to produce eggs, are notorious for transmitting viruses responsible for deadly diseases, such as yellow fever, Dengue, and Zika. Over the years, researchers have devised various solutions, ranging from repellents to vaccines to  to combat the vectors. Now, a team at New York's Rockefeller University has come up with a unique solution to fend off the dangerous insects - filling their little bellies  with diet drugs to curb their appetite for human blood.

Rare Hoodwinker Sunfish Washes Up On California Beach

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.
