Lyra: A small constellation that represents the lyre of Orpheus in Greek mythology. It contains several bright stars, such as Vega, and variable stars, such as Beta Lyrae and RR Lyrae.
Planetary nebulae: Lyra hosts two well-known planetary nebulae, M57 (the Ring Nebula) and Abell 46. They are formed by the ejected material of dying stars, and have different shapes and colors.
Exoplanets: Lyra is one of the constellations observed by the Kepler Mission, which has discovered many exoplanets around other stars. Some of them are in the habitable zone, where liquid water could exist.
Galaxies and gamma-ray bursts: Lyra also contains some distant galaxies, such as NGC 6745, which is colliding with another galaxy, and NGC 6791, which is a cluster of stars with different ages. One of the most remarkable gamma-ray bursts, GRB 050525A, occurred in Lyra in 2005.
