Dark Lunar Eclipse
30.08.2007

The Moon passed close to the center of Earth's shadow on August 28th. Seen best by skywatchers in western North America, and the Pacific region, the resulting total lunar eclipse was a dark one, lasting about 90 minutes.

Earthshine Moon over Sicily

Why can we see the entire face of this Moon? When the Moon is in a crescent phase, only part of it appears directly illuminated by the Sun. The answer is earthshine, also known as earthlight and the da Vinci glow.

Rotating Moon from LRO
19.07.2020

No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has been composed.

Dark Shuttle Approaching
16.02.2010

What's that approaching? Astronauts on board the International Space Station first saw it far in the distance. Soon it enlarged to become a dark silhouette. As it came even closer, the silhouette appeared to be a spaceship.

Teimareh Petroglyphs and Star Trails
12.07.2012

Engraved in rock, these ancient petroglyphs are abundant in the Teimareh valley, located in the Zagros Mountains of central Iran. They likely tell a tale of hunters and animals found in the middle eastern valley 6,000 years ago or more, etched by artists in a prehistoric age.

A Leonid Meteor Explodes
18.11.2001

Last night and tonight, a lucky few may see a meteor explode. As our Earth passes unusually close to debris expelled from Comet Tempel-Tuttle, many sand-sized particles from this comet are entering and burning up in the Earth's atmosphere.

Orion Launch
5.12.2014

Headed for two orbits of planet Earth and a splashdown in the Pacific, Orion blazed into the early morning sky on Friday at 7:05am ET. The spacecraft was launched atop a United Launch Aliance Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida.

The Red Planet Mars
30.07.2020

Mars looks pretty sharp in this backyard telescope image captured on July 23 from Hoegaarden, Belgium, planet Earth. The Red Planet's bright south polar cap is bathed in sunlight at the top of the inverted view, while the dark feature known as Syrtis Major extends toward the right (eastern) edge.

ISS: Sunlight to Shadow
28.02.2008

Orbiting 400,000 kilometers above the Earth, the Moon slid into Earth's shadow to begin last week's total lunar eclipse. Of course the International Space Station (ISS) slides into Earth's shadow every 90 minutes, the time it takes it to complete one orbit at an altitude of about 400 kilometers.

A Flag Shaped Aurora over Sweden
14.03.2021

It appeared, momentarily, like a 50-km tall banded flag. In mid-March of 2015, an energetic Coronal Mass Ejection directed toward a clear magnetic channel to Earth led to one of the more intense geomagnetic storms of recent years. A visual result was wide spread auroras being seen over many countries near Earth's magnetic poles.
