Proceratosaurus

Extinct genus of dinosaurs

Proceratosaurus is a genus of theropod dinosaur that lived during the Middle Jurassic in what is now England. The holotype and only known specimen consists of a mostly complete skull with an accompanying lower jaw and a hyoid bone, found near Minchinhampton, a town in Gloucestershire. It was originally described in 1910 as a species of Megalosaurus, M. bradleyi, but was moved to its own genus, Proceratosaurus, in 1926. The genus was named for its supposed close relationship with Ceratosaurus, later shown to be erroneous, due to perceived resemblance of Proceratosaurus's incomplete cranial crest to Ceratosaurus's nasal horn.

Fish farming

Raising fish commercially in enclosures

Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture, which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans, molluscs and so on, in natural or pseudo-natural environments. A facility that releases juvenile fish into the wild for recreational fishing or to supplement a species' natural numbers is generally referred to as a fish hatchery. Worldwide, the most important fish species produced in fish farming are carp, catfish, salmon and tilapia.

Atlantic salmon

Species of fish

The Atlantic salmon is a species of ray-finned fish in the family Salmonidae. It is the third largest of the Salmonidae, behind Siberian taimen and Pacific Chinook salmon, growing up to 1 m (3.3 ft) in length. Atlantic salmon are found in the northern Atlantic Ocean and in rivers that flow into it. Most populations are anadromous, hatching in streams and rivers but moving out to sea as they grow where they mature, after which the adults seasonally move upstream again to spawn.

Cypress Island Atlantic salmon pen break

2017 ecological disaster in Washington, US

On August 19, 2017, a net pen at a salmon farm near Cypress Island, Washington, broke, accidentally releasing hundreds of thousands of non-native Atlantic salmon into the Pacific Ocean. The fish farm was run by Cooke Aquaculture Pacific, LLC. According to the Washington State Department of Natural Resources, inadequate cleaning was likely the primary cause for the pen break; the nets were supporting more than six times their own weight in biofouling. Coastal tribes were hired to fish the escaped salmon. Atlantic salmon farming was later banned in Washington state in reaction to the incident.

Southern Ontario tornado outbreak of 2005

Series of thunderstorms in Southern Ontario in 2005

The Southern Ontario tornado outbreak of 2005 was a series of thunderstorms on the afternoon of August 19, 2005, that spawned tornadoes damaging homes in the Conestoga Lake, Fergus, and Tavistock areas. A tornado was reported within the Toronto city limits, although this was never officially confirmed by the Meteorological Service of Canada. The storms morphed into heavy rain cells when reaching Toronto. The Insurance Bureau of Canada has estimated that insured losses were the highest in the province's history, exceeding 500 million Canadian dollars, two and a half times that of Ontario's losses during the 1998 ice storm and the second largest loss event in Canadian history until another event of torrential rain of July 8, 2013.

Jim Lovell

American astronaut (1928–2025)

James Arthur Lovell Jr. was an American astronaut, naval aviator, test pilot, and mechanical engineer. In 1968, as command module pilot of Apollo 8, he along with Frank Borman and William Anders, became one of the first three astronauts to fly to and orbit the Moon. He then commanded the Apollo 13 lunar mission in 1970 which, after a critical failure en route, looped around the Moon and returned safely to Earth.

Apollo 13

Aborted Moon landing mission in the Apollo program

Apollo 13 was the seventh crewed mission in the Apollo space program and would have been the third Moon landing. The craft was launched from Kennedy Space Center on April 11, 1970, but the landing was aborted after an oxygen tank in the service module (SM) exploded two days into the mission, disabling its electrical and life-support system. The crew, supported by backup systems on the Apollo Lunar Module, instead looped around the Moon in a circumlunar trajectory and returned safely to Earth on April 17. The mission was commanded by Jim Lovell, with Jack Swigert as command module (CM) pilot and Fred Haise as Lunar Module (LM) pilot. Swigert was a late replacement for Ken Mattingly, who was grounded after exposure to rubella.
