An astonishing school of hammerhead sharks surprises divers at Darwin's Arch in the Galápagos Islands in this majestic video from the BBC's Mission Galápagos series. In an article at Wanderlust, Mission Galápagos host and animal biologist Liz Bonnin lists this adventure as one of her "most amazing wildlife experiences":
The hammerheads come from all different directions and gather, swim around each other in big circles in a wonderful sort of balletic association. At the very centre of this big mass of hammerheads are the oldest, most mature females. The younger sharks swim around them. When the males come in to mate, they’ve got to weave and wind their way through this mass of hammerheads, so only the strongest, fittest males will get to mate with the females in the centre.
We are only just beginning to understand the purpose of this mass congregation, so the more scientists dive down there, the more they’re understanding its importance. It’s a very special place, and a very important behaviour, that needs to be protected. The Galapagos is one of the last jewels of this blue planet of ours. It really needs extra protection of ours oceans to make sure that that doesn’t disappear for ever. It was extraordinary.

More than 125 of these curious soccer ball-sized glass spheres hang near the floor of the Mediterranean Sea. Even though they’re deep underwater, they’re keeping a constant vigil for neutrinos, particles that may be evidence of dark matter, supernovae, and neutron stars far off in intergalactic space. Eventually, the Cubic Kilometer Neutrino Telescope (KM3NeT) will […]
A key challenge in building colonies on the moon is that it’s incredibly expensive to transport construction materials to space from Earth. That’s why researchers are exploring how moon bases could be mostly constructed from raw materials already there. A team of scientists working with the European Space Agency (ESA) are exploring how urine could […]
The new Mars rover Perseverance, set to launch in July for a February 2021 landing, will be outfitted with its own small helicopter. NASA engineers at Kennedy Space Station recently put the chopper through its paces, marking the last time they’ll spin it up before landing on the red planet. From Kennedy Space Center: The […]

There are few things more satisfying than the clickety-clack of an old keyboard. So old, in fact, that it’s really more of a typewriter sound and feel than that of a keyboard. But if you want to enjoy the benefits of both, check out this Rymek Retro Bluetooth 3.0 Mechanical Keyboard. Bringing you an impressive […]
