A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch one astronomical unit.

Spanish ColonialSpanish Colonial stylecolonial
Spanish Colonial architecture represents Spanish colonial influence on New World and East Indies' cities and towns, and it is still being seen in the architecture as well as in the city planning aspects of conserved present-day cities. These two visible aspects of the city are connected and complementary. The 16th century Laws of the Indies included provisions for the layout of new colonial settlements in the Americas and elsewhere.

A sonnet is a poetic form which originated at the Court of the Holy Roman Emperor Frederick II in Palermo, Sicily. The 13th century poet and notary Giacomo da Lentini is credited with the sonnet's invention and the Sicilian School of poets who surrounded him is credited with its spread. The earliest sonnets, however, no longer survive in the original Sicilian dialect, but only after being translated into Tuscan dialect.

The history of Mexico, a country in the southern portion of North America, covers a period of more than three millennia. First populated more than 13,000 years ago, the territory had complex indigenous civilizations before being conquered and colonized by the Spanish in the 16th century. One of the important aspects of Mesoamerican civilizations was their development of writing (the only region of the Americas where writing existed in precolumbian times), so that Mexico's written history stretches back hundreds of years before the arrival of the Spaniards in 1519. This era before the arrival of Europeans is called variously the prehispanic era or the precolumbian era.
Ópata (also Teguima, Eudeve, Heve, Dohema) is either of two closely related Uto-Aztecan languages, Teguima and Eudeve, spoken by the Opata people of northern central Sonora in Mexico. It was believed to be dead already in 1930, and Carl Sofus Lumholtz reported the Opata to have become "Mexicanized" and lost their language and customs already when traveling through Sonora in the 1890s. In a 1993 survey by the Instituto Nacional Indigenista fifteen people in the Mexican Federal District self-identified as speakers of Ópata. This may not mean however that the language was actually living, since linguistic nomenclature in Mexico is notoriously fuzzy.

OpatasOpata peopleÓpata Indians
The Opata (written Ópata in Spanish, pronounced with stress on the first syllable: /ˈopata/) are three indigenous peoples of Mexico. Opata territory, the “Opatería” in Spanish, encompasses the mountainous northeast and central part of the state of Sonora, extending to near the border with the United States. Most Opatan towns were situated in river valleys and had an economy based on irrigated agriculture. In the 16th century, when they first met the Spanish explorers, the Opata were the most numerous people in Sonora. Today, some people continue to identify as Opatas and are working to restore aspects of pre-contact Opata culture, and revitalize Opata identity.

Western ApacheApacheSan Carlos Apache
Oury and Jesús María Elías, who blamed every depredation in southern Arizona on the 500 Camp Grant Apaches, contacted an old ally Francisco Galerita, leader of the Tohono O'odham at San Xavier to punish the Arivaipa.
