The Crab Nebula, and the Crab Pulsar within it, is an intense space X-ray source. It is used as a standard candle in the calibration procedure of X-ray instruments in space. However, because of the Crab Nebula's variable intensity at different X-ray energies, conversion of the Crab to another units depends on the X-ray energy range of interest.
The Crab Pulsar was the first pulsar for which the spin-down limit was broken using several months of data of the LIGO observatory. Most pulsars do not rotate at constant rotation frequency, but can be observed to slow down at a very slow rate (3.7 × 10 −10 Hz/s in case of the Crab). This spin-down can be explained as a loss of rotation ...
It is designed to pursue and interdict fast, non-compliant vessels. As of March 2018, 78 boats have been delivered, and deployed on a variety of cutters, including the Maritime Security Cutters, Hamilton-class High Endurance Cutters, and Famous and Reliance-class Medium Endurance Cutters, and the Sentinel-class cutters.

EBM equipment in construction is similar to electron beam welding machines (see electron beam welding). EBM machines usually utilize voltages in the range of 150 to 200 kV to accelerate electrons to about 200,000 km/s. Magnetic lenses are used to focus the electron beam to the surface of the work-piece. By means of electromagnetic deflection ...

The Crab pulsar 33-millisecond pulse period was too short to be consistent with other proposed models for pulsar emission. Moreover, the Crab pulsar is so named because it is located at the center of the Crab Nebula, consistent with the 1933 prediction of Baade and Zwicky. [ 23 ]
