# Bacon

A strip of pork bacon.

**Bacon** is a type of meat that comes from pigs. It is taken from the sides, back, or belly of the pig. It is often cut in thin slices, unlike other cured or smoked pork products. It is usually fried or grilled. It can also be microwaved.

In the U.S., back bacon and smoked ham is sometimes called Canadian bacon.

Bacon has lots of fat. Because bacon comes from pigs, people of some religions will not eat it. In some cultures and religions (such as Islam and Judaism), eating pork may be considered "unclean." Because of this, other varieties of bacon are also made out of turkey or chicken instead. Turkey bacon and chicken bacon usually contain half of the fat of pork-based bacon.

## Cuts

The type of bacon is different depending on the primal cut of pork it is made of.

* **Side bacon**, sometimes called "streaky bacon", comes from the pork belly. It has long layers of fat and muscle running next to the rind. This is the most common form of bacon in the United States.
	+ Pancetta is an Italian type of side bacon, sold smoked or unsmoked (*aqua*). It is generally rolled into cylinders after it is cured. Pancetta is known for having a strong flavour.
* **Back bacon** is made of meat from the loin in the middle of the back of the pig. It is a leaner cut, with less fat than side bacon. Most bacon in the United Kingdom and Ireland is back bacon.
* **Collar bacon** is taken from the back of a pig near the head.
* **Cottage bacon** is made from the lean meat from a boneless pork shoulder. It is typically tied into an oval shape.
* **Jowl bacon** is cured and smoked pork cheeks.

The inclusion of skin with a cut of bacon is called the 'bacon rind'.

## History

Salted pork belly first appeared in China. In Middle English the term bacon or bacoun meant pork in general. Before the Industrial Revolution, bacon was mostly made on local farms and in home kitchens. The world's first bacon processing plant was opened in Wiltshire in the 1770s.
# Spiral galaxy

A barred spiral galaxy, NGC 1300
A **spiral galaxy** is a kind of galaxy that looks like a flat, slowly rotating disk with a bulge in the centre, and spiral patterns extending outward from the bulge. It contains stars, gas, dust, dark matter and a supermassive black hole at its centre.

Galaxies were long thought to be nebulae. The spiral nebula as a type was first described by Edwin Hubble in his 1936 work *The Realm of the Nebulae*. They are now listed as galaxies, and are named after their shape.

The **barred spiral galaxy** is an important and common type of spiral galaxy. There are three other kinds of spiral galaxies. *Grand-design* spiral galaxies have two well-shaped and well-defined arms. *Multiple-arm* spiral galaxies have more arms. In *flocculent* spiral galaxies, it is hard to see the arms at all, as they are choppy and are ill-defined.

About 60% of galaxies in the universe near us (the 'local universe') are spiral and irregular galaxies. They are mostly found in low-density parts of the universe, and are rare in the centers of galaxy clusters.

## Spiral arms

**Spiral arms** are regions in spiral galaxies. They often contain dust,gas and star clusters of young ,hot and massive stars. They extend from the central bulge area of spiral and barred spiral galaxies. The young, hot and massive stars are why the arms are brighter than the center of the galaxy. Some spiral galaxies have yellow, 'fossil' arms of older stars.

## Milky Way

Our own Milky Way was found to be a spiral galaxy in the early 20th century. In the 1990s it was found to be a barred spiral galaxy. The bar is difficult to see from our position in the Galactic disk. The most convincing evidence for its existence comes from a survey, performed by the Spitzer Space Telescope, of stars in the Galactic center.

# Feces

**Feces** (or **faeces**), also called **poo**, **poop,** or **stool** is the body's solid waste left over from eating food. Human feces leave the intestinal tract and are removed from the body through the anus. Feces are known for their unpleasant odor. The color, which can range from dark green through brown (the most common color) to bright yellow, depends on a lot of different things; for example, different foods can change the color of feces, so can some illnesses, like diarrhea. The consistency of feces changes too. In humans it is measured using the Bristol stool scale, a system for separating feces into seven different types. It is used for medical diagnosis.

Although feces are generally thought to be waste, they actually have many uses. Feces are used by some scientists to follow animal populations. Feces from animals and humans can be used to create fertilizers for plant crops. Some feces are also used as a fuel for fires.

Animals can also poop. In informal language, there are many words for feces. These are often offensive or even vulgar.

In popular culture, there are a few books about feces. Most of these books are for children. One is called *Everyone Poops*. It was written by Tarō Gomi, who is from Japan.
