In the vast tapestry of the night sky, constellations have captivated humans for millennia. Each one, a collection of stars seemingly connected by an invisible thread, tells a story, a myth, or a legend passed down through generations. Among these celestial figures, Corvus, the Crow, stands out as a constellation steeped in history and celestial beauty.
Located in the southern hemisphere, Corvus is a relatively small but easily recognizable constellation. Its four main stars form a distinct quadrilateral, resembling a flying crow or a kite. This simple shape, coupled with its proximity to the brilliant star Spica in the constellation Virgo, makes Corvus a standout in the night sky.
The Mythological Origins:
The myth associated with Corvus is a compelling tale of betrayal and punishment. In Greek mythology, Apollo, the god of the sun and music, entrusted his beloved Corvus, the crow, with a cup of water for Asclepius, the god of healing. However, the crow, tempted by the ripe fruits of a fig tree, lingered and delayed its task. To conceal his tardiness, Corvus brought a water snake as an excuse. This deceit enraged Apollo, who punished the crow by placing it in the sky, forever carrying the cup of water.

Instructions: You are tasked with creating a short presentation about Corvus for a group of amateur astronomers.
Tasks:
Note: You can use online resources, astronomy books, and star charts to gather information.
The exercise does not have a single correct answer. The goal is to encourage research and creative presentation skills. A good presentation would be informative, engaging, and visually appealing. It could include facts like: * Corvus is a circumpolar constellation in the southern hemisphere, meaning it can be seen year-round. * Corvus is the only constellation associated with a bird with a negative meaning. * The constellation contains several double stars that can be observed with binoculars. * Corvus is often depicted in star charts as a crow perched on a cup, which could represent the myth associated with it. The visual aid could be a constellation map, a photo of the sky showing Corvus, a drawing of the constellation, or a presentation slide with relevant information.
