Ques: Information:  - In astronomy and navigation, the celestial sphere is an imaginary sphere of arbitrarily large radius, concentric with Earth. All objects in the observer's sky can be thought of as projected upon the inside surface of the celestial sphere, as if it were the underside of a dome or a hemispherical screen. The celestial sphere is a practical tool for spherical astronomy, allowing observers to plot positions of objects in the sky when their distances are unknown or unimportant.  - NGC 6755 is an open cluster in the constellation Aquila.  - An open cluster is a group of up to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way Galaxy, and many more are thought to exist. They are loosely bound by mutual gravitational attraction and become disrupted by close encounters with other clusters and clouds of gas as they orbit the galactic center. This can result in a migration to the main body of the galaxy and a loss of cluster members through internal close encounters. Open clusters generally survive for a few hundred million years, with the most massive ones surviving for a few billion years. In contrast, the more massive globular clusters of stars exert a stronger gravitational attraction on their members, and can survive for longer. Open clusters have been found only in spiral and irregular galaxies, in which active star formation is occurring.  - NGC 6756 is a small open star cluster in the constellation Aquila , close to NGC 6755 .  - A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes.  - The International Astronomical Union (IAU UAI) is an international association of professional astronomers, at the PhD level and beyond, active in professional research and education in astronomy. Among other activities, it acts as the internationally recognized authority for assigning designations to celestial bodies (stars, planets, asteroids, etc.) and any surface features on them.  - A constellation is formally defined as a region of the celestial sphere, with boundaries laid down by the International Astronomical Union (IAU). The constellation areas mostly had their origins in Western-traditional patterns of stars from which the constellations take their names.

Ques: Information:  - Violin is a novel by American horror writer Anne Rice , released on 15 October 1997 . It moves away from her previous stories about vampires and witches to tell a ghost story .  - Christian literature is writing that deals with Christian themes and incorporates the Christian world view. This constitutes a huge body of extremely varied writing.  - Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance. Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story." The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel. It originated in England in the second half of the 18th century and had much success in the 19th, as witnessed by Mary Shelleys "Frankenstein" and the works of Edgar Allan Poe. Another well known novel in this genre, dating from the late Victorian era, is Bram Stokers "Dracula". The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place. This extreme form of romanticism was very popular in England and Germany. The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".  - Interview with the Vampire is a debut gothic horror and vampire novel by American author Anne Rice, published in 1976. Based on a short story Rice wrote around 1968, the novel centers on vampire Louis de Pointe du Lac, who tells the story of his life to a reporter. Rice composed the novel shortly after the death of her young daughter Michelle, who served as an inspiration for the child-vampire character Claudia. Though initially the subject of mixed critical reception, the book was followed by a large number of widely popular sequels, collectively known as "The Vampire Chronicles". A film adaptation was released in 1994, starring Brad Pitt and Tom Cruise, and the novel has been adapted as a comic three times.  - Anne Rice (born Howard Allen Frances O'Brien; October 4, 1941) is an American author of gothic fiction, Christian literature, and erotica. She is perhaps best known for her popular and influential series of novels, "The Vampire Chronicles", revolving around the central character of Lestat. Books from "The Vampire Chronicles" were the subject of two film adaptations, "Interview with the Vampire" in 1994, and "Queen of the Damned" in 2002.  - The Vampire Chronicles is a series of novels by Anne Rice that revolves around the fictional character Lestat de Lioncourt, a French nobleman turned into a vampire in the 18th century.  - Erotica (from the Greek , "eros" "desire") is any artistic work that deals substantively with erotically stimulating or sexually arousing subject matter. All forms of art may depict erotic content, including painting, sculpture, photography, drama, film, music or literature. Erotica has high-art aspirations, differentiating it from commercial pornography.
