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 ...
Target Comics v3 7, art by Basil Wolverton, September 1942. Born in Central Point, Oregon, he later moved to Vancouver, Washington, and worked as a vaudeville performer and a cartoonist and reporter for the Portland News. At age 16 he sold his first nationally published work and began pitching comic strips to newspaper syndicates.
The Crab Nebula is a remnant of an exploded star. This is the Crab Nebula in various energy bands, including a hard X-ray image from the HEFT data taken during its 2005 observation run. Each image is 6' wide. The guest star reported by Chinese astronomers in 1054 is identified as SN 1054. The highlighted passages refer to the supernova.
The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope.

This is a list of cartoonists, visual artists who specialize in drawing cartoons.This list includes only notable cartoonists and is not meant to be exhaustive. Note that the word 'cartoon' only took on its modern sense after its use in Punch magazine in the 1840s - artists working earlier than that are more correctly termed 'caricaturists',
The map the cartoon uses for Lapland is of the Kola Peninsula while the statistics for Lapland are for the Finnish province of Lappi.) In one part of this cartoon it is also stated "If you wanted to open a strip club, Lapland would be a possible name". In 2008, a version making light of the recent pirating in Somalia was created. It has the ...

Pulsar wind nebulae evolve through various phases. [2] [5] New pulsar wind nebulae appear soon after a pulsar's creation, and typically sit inside a supernova remnant, for example the Crab Nebula, [6] or the nebula within the large Vela Supernova Remnant. [7] As the pulsar wind nebula ages, the supernova remnant dissipates and disappears.
