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 […]
On July 16, 2024, the Artemis II core stage rolled out of the Vertical Assembly Building to the waiting Pegasus barge at NASA’s Michoud Assembly Facility in New Orleans in preparation for delivery to Kennedy Space Center. via NASA https://ift.tt/eHAYSD3
Unlike most entries in Charles Messier’s famous catalog of deep sky objects, M24 is not a bright galaxy, star cluster, or nebula. It’s a gap in nearby, obscuring interstellar dust clouds that allows a view of the distant stars in the Sagittarius spiral arm of our Milky Way galaxy. Direct your gaze through this gap […]
“I found out years later that seeing me in high school and hearing my experience in college inspired her to major in physics, and so she became the first robotics director at her school. And now she’s a principal. And it just rocked me because I was just being me and trying to share. It […]
