The Crab Nebula is the remnant of a supernova which was observed almost 1000 years ago. Although it corresponds to one of the most studied celestial objects, its extension in very high energy ...

The Crab Pulsar, a remnant of a supernova whose explosion was visible from Earth in 1054, emits a mysterious radio signal known as the "zebra" pattern. This signal has long intrigued scientists ...

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.

It contains a pulsar, designated PSR J1811−1925, and a pulsar wind nebula. The PWN in G11.2−0.3 is powered by PSR J1811−1925, which is located near the SNR's shell.

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 supernova remnant ...
