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 ...
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.

A L. beagle washed ashore off Western Australia's south coast and was found by a Danish family, who sent it to the Western Australia Museum for identification. Andrew Hosie, a crustacean and worm curator at the Western Australian Museum, and Colin McLay, a marine biologist affiliated with the University of Canterbury in New Zealand, then described the crab as a new species, one of the three ...
Dogs exhibiting the happy right variety are deemed approachable, while the lefty waggers are not. Number 4: Tail shaking is an acquired skill. Puppies begin to learn the ins and outs of it when ...
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.
Bisque (food) – a smooth, creamy, highly seasoned soup of French origin, classically based on a strained broth of crustaceans. It can be made from lobster, crab, shrimp or crayfish. Black pepper crab – one of the two most popular ways that crab is served in Malaysia and Singapore. It is made with hard-shell crabs, and fried with black pepper
Hepatus epheliticus, known by various names, including the calico crab (not to be confused with Ovalipes ocellatus) and Dolly Varden crab, is a species of crab. It lives in shallow water in the western Atlantic Ocean from the Chesapeake Bay to the Dominican Republic .
Scopimera globosa and the sand pellets it has made. Sand bubbler crabs live in burrows in the sand, where they remain during high tide. When the tide is out, they emerge on to the surface of the sand, and pass the sand through their mouthparts, eating detritus and plankton, [5] and discarding the processed sand as pellets, which cover the beach.
