Crab Nebula

Crab Nebula
(Image and Text Credit: NASA/CXC/SAO)

The explosion was seen on Earth in 1054 AD. At the center of the nebula is a rapidly spinning neutron star, or pulsar that emits pulses of radiation 30 times a second. The image shows the central pulsar surrounded by tilted rings of high-energy particles that appear to have been flung outward over a distance of more than a light year from the pulsar. Perpendicular to the rings, jet-like structures produced by high-energy particles blast away from the pulsar. The diameter of the inner ring in the image is about a tenth of a light year, more than 200 times the diameter of our solar system. The X rays from the Crab nebula are produced by high-energy particles spiraling around magnetic field lines in the Nebula. The bell-shaped appearance of the Nebula could be due to the interaction of this huge magnetized bubble with clouds of gas and dust in the vicinity. Chandra X-ray Observatory

The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.
