Our Moon doesn’t really have craters this big. Earth’s Moon, Luna, also doesn’t naturally show this spikey texture, and its colors are more subtle. But this digital creation is based on reality. The featured image is a digital composite of a good Moon image and surface height data taken from NASA’s Lunar Orbiter Laser Altimeter […]

What powers the Crab Nebula? A city-sized magnetized neutron star spinning around 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula’s core. About 10 light-years across, the spectacular picture of the Crab Nebula (M1) frames a swirling central disk and […]
The barred spiral galaxy NGC 6872 is interacting with a smaller galaxy to the upper left. The smaller galaxy has likely stripped gas from NGC 6872 to feed the supermassive black hole in its center. via NASA https://ift.tt/XkIN9RP
Sometimes the dark dust of interstellar space has an angular elegance. Such is the case toward the far-south constellation of Chamaeleon. Normally too faint to see, dark dust is best known for blocking visible light from stars and galaxies behind it. In this 36.6-hour exposure, however, the dust is seen mostly in light of its […]
This rock structure is not only surreal — it’s real. Perhaps the reason it’s not more famous is that it is smaller than one might guess: the capstone rock overhangs only a few meters. Even so, the King of Wings outcrop, located in New Mexico, USA, is a fascinating example of an unusual type of […]
Have you seen a panorama from another world lately? Assembled from high-resolution scans of the original film frames, this one sweeps across the magnificent desolation of the Apollo 11 landing site on the Moon’s Sea of Tranquility. The images were taken 55 years ago by Neil Armstrong looking out his window on the Eagle Lunar […]

For some, these subtle bands of light and shadow stretched across the sky as the Sun set on July 11. Known as anticrepuscular rays, the bands are formed as a large cloud bank near the western horizon cast long shadows through the atmosphere at sunset. Due to the camera’s perspective, the bands of light and […]
