Birds During a Total Solar Eclipse

What do birds do during a total solar eclipse? Darkness descends more quickly in a total eclipse than during sunset, but returns just as quickly — and perhaps unexpectedly to the avians — just a few minutes later. Stories about the unusual behavior of birds during eclipses have been told for centuries, but bird reactions were recorded and studied systematically by citizen scientists participating in an eBird project during the … Read More →

The Galactic Center in Radio from MeerKAT

What’s happening at the center of our galaxy? It’s hard to tell with optical telescopes since visible light is blocked by intervening interstellar dust. In other bands of light, though, such as radio, the galactic center can be imaged and shows itself to be quite an interesting and active place. The featured picture shows the inaugural image of the MeerKAT array of 64 radio dishes just completed in South Africa. … Read More →

Crescent Saturn

Saturn never shows a crescent phase — from Earth. But when viewed from beyond, the majestic giant planet can show an unfamiliar diminutive sliver. This image of crescent Saturn in natural color was taken by the robotic Cassini spacecraft in 2007. The featured image captures Saturn’s majestic rings from the side of the ring plane opposite the Sun — the unilluminated side — another vista not visible from Earth. Pictured … Read More →

La Silla Eclipse Sequence

The road to the high mountaintop La Silla Observatory in the Chilean Atacama Desert also led in to the path of July 2nd’s total solar eclipse. Recorded at regular intervals before and after the total eclipse phase, the frames in this composite sequence include the moment the Moon’s dark shadow fell across some of planet Earth’s advanced large telescopes. The dreamlike view looks west toward the setting Sun and the … Read More →

Robotic Dragonfly Selected to Fly Across Titan

If you could fly across Titan, what would you see? To find out and to better explore this exotic moon of Saturn, NASA recently green-lighted Dragonfly, a mission to Titan with plans to deploy a helicopter-like drone. Saturn’s moon Titan is one of the largest moons in the Solar System and the only moon known to have a thick atmosphere and changing hydrocarbon lakes. After development, building, testing, and launch, … Read More →
