Fifty years of data show spring and fall bird migrations changing

Bird-banding data in North America shows a spring migration pattern that's become progressively earlier with each of the last 5 decades, and a fall migration that's lasting longer than 50 years ago.

Cosmic rays and Titan’s organic molecules

A new study from researchers in Tokyo helps explain how cosmic rays affect prebiotic organic chemistry in the atmosphere of Saturn's moon Titan.

African dust bombards the Canary Islands

These hot, dust-laden winds are known as “la calima” and happen most often in winter. They can blow at up to 75 mph (120 kph). The dust kicked up last weekend in Africa drifted over the Canary Islands, shutting down airports and stranding travelers.

Using radio waves to discover and study exoplanets

A new study from researchers in the Netherlands shows how scientists can detect exoplanets orbiting red dwarf stars, and learn about their environments, from the radio waves generated by auroras on those worlds.

Did early humans in Africa interbreed with a mysterious, extinct species?

New research suggests that early humans in Africa interbred with a ghost population that likely split from the ancestors of humans and Neanderthals between 360,000 and 1.02 million years ago.

Watch for the moon and Venus this week

You might not see the moon on February 24. It might be too close to the sunset. Observers in North America, though, do have a shot at Monday evening's moon. And every evening after that, you'll surely see the waxing crescent moving up past bright Venus!

Why does Arrokoth look like a snowman?

Meet Arrokoth - the most distant object yet visited by earthlings - seen by the New Horizons spacecraft in early 2019. It's very old, one of the first generation of objects in our solar system. Here's why it looks like a snowman.

A major ocean current in the Arctic is faster and more turbulent as a result of rapid sea ice melt, according to a new study.

A bee from the age of dinosaurs

One hundred million years ago, a bee got trapped in tree resin. Over time, geological forces converted the resin to amber. Now a scientist arrives on the scene, to tell us this bee’s story.
