Astronomers have figured out how to use the gravity of distant galaxies to bend light and magnify images, forming gigantic telescopes that see deeper into the cosmos than ever before.
Millions of people have been watching the live web view of the baby eaglet – named B3 – that hatched February 22, and his two parents, thanks to the bald eagle nest cam from Georgia’s Berry College.
If you watch this three-minute long trailer for the new Cosmos without wanting to tune in to the whole series … you are made of sterner stuff than me.
Steve Mould, a host of science television shows in the UK, stumbled on the chain fountain while he was looking for a way to demonstrate something else. Mould, who has a master’s degree in physics from Oxford, discovered a rising curve in a moving chain of beads as the beads flow out of a container. Once he starts it, the bead chain keeps going, like water or gasoline being siphoned from a tank. Why?
Scientists at the University of Hawaii and University of Tokyo are gaining new insights into the movements and behaviors of sharks using video cameras and sensors attached to the animals. They’ve also started a project that examines eating habits of sharks and other top ocean predators like tuna using small instruments, electronic pills, that can be ingested by the creatures.
Satellite video captures the awesome power of the winter storms that hit the eastern U.S. on the first days of March.
A quadcopter drone was used to capture this amazing video. If you watch it all, you’ll see thousands of common dolphins stampeding off Dana Point, California, three gray whales migrating together down the coast off San Clemente, California, plus, toward the end, close-ups from Maui of a newborn Humpback whale calf snuggling and playing with its mom, as an escort whale stands guard nearby. Definitely worth five minutes!
The Arctic is home to a growing number of whales and ships, and to populations of sub-Arctic whales that are expanding their territory into newly ice-free Arctic waters. A study of the narrow passage of the Bering Strait uses underwater microphones to track the whales by their sounds.
Justin Ng wrote to say he had compiled a number of shots of the Milky Way over Singapore – a major city known for its heavily light-polluted skies – into this beautiful video. He wrote:
This movie aims to … inspire more astrophotographers residing in heavily light polluted cities to unveil the beauty of the elusive Milky Way galaxy.
When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable trophic cascade occurred. The wolves have affected not just the surrounding living ecosystems, but the physical geography of the land itself.
