Green Flashes: Sun, Moon, Venus, Mercury

Follow a sunset on a clear day against a distant horizon and you might glimpse green just as the Sun disappears from view. The green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere. Shorter wavelengths refract more strongly than longer redder wavelengths and the separation of colors lends a green hue to the last visible vestige of the solar … Read More →

Mercury Meets Crescent Venus

That’s not a bright star and crescent Moon caught between branches of a eucalyptus tree. It’s Venus in a crescent phase and Mercury. Near the western horizon after sunset, the two inner planets closely shared this telescopic field of view on May 22, seen from a balcony in Civitavecchia, Italy. Venus, the very bright celestial beacon, is wandering lower into the evening twilight. It grows larger in apparent size and … Read More →

The familiar constellation of Orion can be seen left of the trail of the orbital station’s bright passage. On the right, Venus is the brilliant evening star above the western horizon. With the camera fixed to a tripod, this scene was captured in a series … Read More →

Earth and Moon through Saturns Rings

What are those dots between Saturn’s rings? Our Earth and Moon. Just over three years ago, because the Sun was temporarily blocked by the body of Saturn, the robotic Cassini spacecraft was able to look toward the inner Solar System. There, it spotted our Earth and Moon — just pin-pricks of light lying about 1.4 billion kilometers distant. Toward the right of the featured image is Saturn’s A ring, with … Read More →
