On Feb. 22, 1971, a sounding rocket lifted off from Wallops Island, Virginia, with specialized sensors aimed at the Crab Nebula, a bright cosmic object 6,500 light-years away. In those days, before ...

THE existence of a source in the Crab Nebula with an angular diameter of less than 1 sec of arc has been revealed by observations of interplanetary scintillation at a frequency of 38 Mc/s (ref. 1).

Cocke, W. J., Disney, M. J., and Taylor, D. J., IAU Circ. No. 2128 (January 20, 1969). Howard, W. E., Staelin, D. H., and Reifenstein, E. C., IAU Circ. No. 2110 ...

A theoretical astrophysicist may have solved a nearly two-decade-old mystery over the origins of an unusual 'zebra' pattern seen in high-frequency radio pulses from the Crab Nebula. A theoretical ...

The Crab nebula is blasting high-energy gamma rays at us. Researchers using the Large High Altitude Air Shower Observatory (LHAASO) in China have found the second highest-energy gamma ray, or photon, ...

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern. LAWRENCE — A ...

ABSTRACT Published images of the Crab Nebula have been scanned and measured to derive proper motions, the age of the nebula, and its point of origin. Astrometric reductions provided rms errors ranging ...

A new movie from NASA’s Chandra X-ray Observatory shows a sequence of Chandra images of the Crab Nebula, taken over an interval of seven months. Dramatic variations are seen, including the expansion ...

The James Webb Space Telescope has revealed the most detailed image so far of the Crab Nebula, a gorgeous supernova remnant of a star that exploded 1,000 years ago. When you purchase through links on ...

This image by NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) shows different structural details of the Crab Nebula. The observations were taken as ...
