Moose battle frozen in ice

The sight of two powerful bull moose locking horns in combat is something that metaphorically can become frozen in time for those lucky enough to experience such an event, but for a pair of Alaskan hikers, they were lucky enough  to see such a battle literally frozen in time.

As National Geographic explained on Friday, Brad Webster, a science and social studies teacher working at a Bible camp near the city of Unalakleet, was hiking along the Bering Sea earlier this month when he found the duo entombed together in a layer of ice thick enough to walk on.

10 Times More Galaxies Than Previously Thought

The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA’s Hubble Space Telescope and other observatories.

Astronomers came to the surprising conclusion that there are at least 10 times more galaxies in the observable universe than previously thought.

The results have clear implications for galaxy formation, and also helps shed light on an ancient astronomical paradox — why is the sky dark at night?

Dinosaurs sprinted across the planet

The smallest dinosaur could reach speeds of about 60 kilometres per hour and even the lumbering Tyrannosaurus rex would have been able to outrun most modern sportsmen, according to new research.

Scientists using computer models calculated the top speeds for five meat-eating dinosaurs in a study they say can also illustrate how animals cope with climate change and extinction.

The velociraptor, whose speed and ferocity was highlighted in the film Jurassic Park, reached about 40 kilometres per hour, according to the study published in the Royal Society journal Biological Sciences.

Bizarre Hexagon on Saturn Shines

A stunning new photo of Saturn’s north pole spotlights the planet’s bizarre hexagon-shaped vortex and beautiful bands of swirling winds.

NASA’s Cassini spacecraft captured this dramatic view on Sept. 5, as the probe flew 890,000 miles (1.4 million kilometers) above the planet. The image, which NASA released Monday (Nov. 14), looks toward the sunlit side of Saturn’s rings.

The Trees Have Ears

Environmentalists are bugging rainforests with discarded smartphones to catch poachers and illegal loggers.

When a tree falls to illegal loggers in the forest of the Kalaweit Supayang Nature Conservation Reserve for gibbons in West Sumatra, Indonesia, it most definitely makes a sound—and generates a text message to alert reserve managers. Last summer a tiny, nonprofit start-up called Rainforest Connection installed a handful of old, donated smartphones, each tricked out with a solar charger and reprogrammed to conduct audio surveillance, into the forest canopy. The system quickly brought logging to a halt, says Topher White, a 31-year-old physicist who designed the system and founded the outfit.
