Birds During a Total Solar Eclipse
9.07.2019
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.
The Galactic Center in Radio from MeerKAT
8.07.2019
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.
Crescent Saturn
7.07.2019
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.
8 Minute and 30 Second Eclipse
6.07.2019
The total phase of the July 2nd solar eclipse lasted about 4 minutes and 30 seconds at the point of maximum eclipse. On the surface of planet Earth, that was about 600 nautical miles north of Easter Island in the Southern Pacific Ocean.
La Silla Eclipse Sequence
5.07.2019
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...
In the Shadow of the Moon
4.07.2019
On July 2 denizens of planet Earth could stand in the Moon's dark umbral shadow during South America's 2019 total solar eclipse. It first touched down in the Southern Pacific Ocean, east of New Zealand.
Robotic Dragonfly Selected to Fly Across Titan
3.07.2019
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.
NGC 1566: The Spanish Dancer Spiral Galaxy
2.07.2019
If not perfect, then this spiral galaxy is at least one of the most photogenic. An island universe containing billions of stars and situated about 40 million light-years away toward the constellation of the Dolphinfish (Dorado), NGC 1566 presents a gorgeous face-on view.
The Big Corona
1.07.2019
Most photographs don't adequately portray the magnificence of the Sun's corona. Seeing the corona first-hand during a total solar eclipse is unparalleled. The human eye can adapt to see coronal features and extent that average cameras usually cannot. Welcome, however, to the digital age.
Virtual Flight over Asteroid Vesta
30.06.2019
What would it be like to fly over the asteroid Vesta? Animators from the German Aerospace Center took actual images and height data from NASA's Dawn mission when it visited asteroid Vesta a few years ago and generated a virtual movie.
