Returning from beyond the Moon, on December 11 the Orion spacecraft entered Earth’s atmosphere at almost 11 kilometers per second. That’s half the speed of the grain of dust that created this long fireball meteor when it entered the atmosphere on December 13, near the peak of the annual Geminid meteor shower. As our fair […]

On December 8 a full Moon and a full Mars were close, both bright and opposite the Sun in planet Earth’s sky. In fact Mars was occulted, passing behind the Moon when viewed from some locations across Europe and North America. Seen from the city of Kosice in eastern Slovakia, the lunar occultation of Mars […]

Why is the Moon so dusty? On Earth, rocks are weathered by wind and water, creating soil and sand. On the Moon, the history of constant micrometeorite bombardment has blasted away at the rocky surface creating a layer of powdery lunar soil or regolith. For the Apollo astronauts and their equipment, the pervasive, fine, gritty […]

Can the night sky be both art and science? If so, perhaps the featured image is an example. The digital panorama was composed of 10 landscape and 10 sky images all taken on the same night, from the same location, and with the same camera. Iconic features in the image have been artfully brightened, and […]
