What's the largest waterfall in the world?
If your mind has gone straight to the thundering waters cascading down Venezuela's Angel Falls, think again.

A dog-like, bio-inspired robot called Spirit is still learning to walk, but could one day be deployed on the moon to explore steep, potentially hazardous areas with a team of robot companions.
A surprise coronal mass ejection recently smashed into Comet 12P/Pons-Brooks, briefly causing the "devil comet" to lose its tail — and a NASA spacecraft caught the whole thing on camera.
During the historic April 8 total solar eclipse, a government radio station in Colorado started sending out slightly shifted "time signals" to millions of people across the globe as the moon's shadow altered the upper layers of our atmosphere. However, these altered signals did not actually change the time.
Underwater archaeologist and author David Gibbins discusses his new book about shipwrecks around the world.
Major cities across eastern China are sinking due to groundwater extraction and the weight of buildings, potentially exposing millions of people to flooding and damage in the next 100 years.
Researchers discovered the remains of a huge dinosaur named Bustingorrytitan shiva last year and have now released artistic reconstructions of the Cretaceous giant.
Visitors at Ranthambore National Park in India captured rare footage and images of a tigress and her three 1-year-old cubs feasting on the carcass of a crocodile after killing it.
From Titanoboa and Vasuki — prehistoric snakes as long as a Tyrannosaurus rex — to modern-day pythons and boa constrictors that can swallow humans whole, these are the biggest, heaviest and longest snakes to have ever lived on Earth.
Africa's soda lakes are rising and it's decimating the cyanobacteria flamingos have evolved to eat, putting the species at risk of drastic declines if current trends continue.
April's full moon, nicknamed the Pink Moon, rises on Tuesday (April 23), but will appear bright and full on Monday and Wednesday as well. Here's how to see it at its best.
A fringe theory called "panspermia" suggests that lifeforms can spread to new planets by hitching rides on meteors. New research lays out a roadmap for finding where these hypothetical, planet-hopping aliens may reside.
Qubits can be made by floating a suspended electron over a pool of liquid helium rather than being embedded them a solid-state crystal — which leads to impurities and errors.
Archaeologists think veneration of the freshwater spring started in Neolithic times.
By precisely measuring the mass of neutrinos — ghostly particles that stream through your body by the billions each second — physicists could find some glaring holes in the Standard Model of particle physics. A new experiment has taken them one step closer.
The mysterious monument site appears to have been occupied across multiple historical periods.
On many exoplanets, the best clue that life is present may be a purple hue. New research into some of Earth's most extreme bacteria explains why.
Several bacteria that can cause deadly bloodstream infections in humans are attracted to an amino acid in our blood, scientists have discovered.
Scientists want to replace electrons with so-called 'nanobubbles' — or skyrmions — to store data more densely and efficiently in advanced memory components that would replace RAM and flash storage.
