A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of solar radiation and the outstreaming solar wind plasma 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 beyond one astronomical unit. If sufficiently close and bright, a comet may be seen from Earth without the aid of a telescope and can subtend an arc of up to 30° across the sky. Comets have been observed and recorded since ancient times by many cultures and religions.
Ancient art refers to the many types of art produced by the advanced cultures of ancient societies with different forms of writing, such as those of ancient China, India, Mesopotamia, Persia, Palestine, Egypt, Greece, and Rome. The art of pre-literate societies is normally referred to as prehistoric art and is not covered here. Although some pre-Columbian cultures developed writing during the centuries before the arrival of Europeans, on grounds of dating these are covered at pre-Columbian art and articles such as Maya art, Aztec art, and Olmec art.
Pula, also known as Pola, is the largest city in Istria County, Croatia, and the seventh-largest city in the country, situated at the southern tip of the Istrian peninsula in western Croatia, with a population of 52,220 in 2021. It is known for its multitude of ancient Roman buildings, the most famous of which is the Pula Arena, one of the best preserved Roman amphitheaters. The city has a long tradition of wine making, fishing, shipbuilding, and tourism. It was the administrative centre of Istria from ancient Roman times until superseded by Pazin in 1991.
Mostar is a city and the administrative centre of Herzegovina-Neretva Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina, and the historical capital of Herzegovina.
A gravestone or tombstone is a marker, usually stone, that is placed over a grave. A marker set at the head of the grave may be called a headstone. An especially old or elaborate stone slab may be called a funeral stele, stela, or slab. The use of such markers is traditional for Chinese, Jewish, Christian, and Islamic burials, as well as other traditions. In East Asia, the tomb's spirit tablet is the focus for ancestral veneration and may be removable for greater protection between rituals. Ancient grave markers typically incorporated funerary art, especially details in stone relief. With greater literacy, more markers began to include inscriptions of the deceased's name, date of birth, and date of death, often along with a personal message or prayer. The presence of a frame for photographs of the deceased is also increasingly common.

The Lipizzan or Lipizzaner is a European breed of riding horse developed in the Habsburg Empire in the sixteenth century. It is of Baroque type, and is powerful, slow to mature and long-lived; the coat is usually gray.
The Kreutz sungrazers are a family of sungrazing comets, characterized by orbits taking them extremely close to the Sun at perihelion. At the far extreme of their orbits, aphelion, Kreutz sungrazers can be a hundred times farther from the Sun than the Earth is, while their distance of closest approach can be less than twice the Sun's radius. They are believed to be fragments of one large comet that broke up several centuries ago and are named for German astronomer Heinrich Kreutz, who first demonstrated that they were related. These sungrazers make their way from the distant outer Solar System to the inner Solar System, to their perihelion point near the Sun, and then leave the inner Solar System in their return trip to their aphelion.
Ancient Egyptian art refers to art produced in ancient Egypt between the 6th millennium BC and the 4th century AD, spanning from Prehistoric Egypt until the Christianization of Roman Egypt. It includes paintings, sculptures, drawings on papyrus, faience, jewelry, ivories, architecture, and other art media. It was a conservative tradition whose style changed very little over time. Much of the surviving examples comes from tombs and monuments, giving insight into the ancient Egyptian afterlife beliefs.
The nucleus is the solid, central part of a comet, formerly termed a dirty snowball or an icy dirtball. A cometary nucleus is composed of rock, dust, and frozen gases. When heated by the Sun, the gases sublime and produce an atmosphere surrounding the nucleus known as the coma. The force exerted on the coma by the Sun's radiation pressure and solar wind cause an enormous tail to form, which points away from the Sun. A typical comet nucleus has an albedo of 0.04. This is blacker than coal, and may be caused by a covering of dust.
Muggia is an Italian town and comune (municipality) in south-eastern regional decentralization entity of Trieste, in the region of Friuli-Venezia Giulia on the border with Slovenia.

Puckett Observatory is a private astronomical observatory located in the state of Georgia. It is owned and operated by Tim Puckett. Its primary observation goals are the study of comets and the discovery of supernovae. To facilitate the latter goal it sponsors the Puckett Observatory World Supernova Search whose astronomers have discovered 369 supernovae.
Tanya Preminger, is an artist working in various media: environmental art, site-specific art, ephemeral art, sculpture, installation and photography. She is mostly known for her land art projects and large-scale stone sculptures.
The Calcare di Aurisina is a Mesozoic geologic formation in Italy and Slovenia. This limestones are found in the Trieste area and are of Late Cretaceous (Santonian-Campanian) age, being a local record of Carbonate platform limestones, historically quarried by cutting large blocks using steel wire, what has allowed more access to them, as numerous quarries allow excellent exposure. Due to being cut into large blocks and slabs, that usually end stored near the quarries, detailed, three-dimensional study of the rock's composition and fossils can be easily done.
Istrian Italians are an ethnic group from the Adriatic region of Istria in modern northwestern Croatia and southwestern Slovenia. Istrian Italians descend from the original Latinized population of Roman Histria, from the Venetian-speaking settlers who colonized the region during the time of the Republic of Venice, and from the local Croatian people who culturally assimilated.
Flexible stone veneer is a veneer with a layer of stone 1 to 5 mm thick. Flexible stone veneers should not be confused with traditional stone veneers. It is used for both interior and exterior and especially where bending to a curved surface is required. Flexible stone veneers are made from various types of slate, schist, or marble.
Slobodan Pejić was a Bosnian sculptor and painter who lived for most of his life in Slovenia. He is best known after having transformed a 300-year-old oak tree that fell in the storm in Tivoli Park in Ljubljana into the sculpture Coexistence in 2000, proposing with the act the beginning of a sculpture garden in the park. He painted numerous frescos in Bosnia and Croatia. In addition, he invented a new technique in sculpture, based on moulding and gas expansion. He was for many years the Ljubljana correspondent of the Tanjug press agency.
Eugen Ciucă was a Romanian-American artist known for his monumental sculptures, vivid paintings and drawings of delicate feminine figures. He spent the most successful years of his career in Italy, where he created many works inspired by the Divine Comedy and its author Dante Alighieri.
