LBN 765 is a designation for a specific astronomical object, classified as a nebula. It is located in the constellation of Cassiopeia and is known for its striking appearance and complex structure. Nebulae like LBN 765 are often regions where new stars are born, as they contain gas and dust that can collapse under gravity. This nebula is part of a larger group of dark nebulae, which are clouds of gas and dust that block light from objects behind them. Dark nebulae are important for studying the formation of stars and planetary systems, as they provide insights into the early stages of stellar evolution.
