This week’s stargazing focus centers on Lyra, a relatively compact constellation that occupies a prominent position in the evening sky for northern hemisphere observers. The constellation becomes easily identifiable through its brightest star, Vega, which ranks as the fifth-brightest star visible from Earth. From London at 22:30 BST on 17 August, Vega appears high overhead when facing south toward the zenith.
Vega forms a significant asterism known as the summer triangle, with two other prominent stars—Deneb in the constellation Cygnus and Altair in Aquila—marking the remaining vertices of this recognizable pattern. Once observers locate Vega, tracing the remaining stars of Lyra becomes straightforward, though these companion stars are considerably fainter than the primary marker.
Lyra holds historical significance as one of the 48 original constellations catalogued by the second-century astronomer Ptolemy. The constellation stands out among star patterns for bearing a genuine resemblance to the object it represents—a lyre or harp. According to classical tradition, the pattern commemorates the legendary musical instrument played by Orpheus, the Greek poet renowned in mythology for his extraordinary musical abilities.
In ancient Greek stories, Orpheus possessed such exceptional talent that his music could tame wild creatures, move inanimate objects, and appeal to divine beings. During his participation in the Argonauts’ expedition, Orpheus’s performances shielded his fellow crew members from the dangerous enchantments of the Sirens. Observers in the southern hemisphere can also view Lyra during August evenings, though the constellation appears considerably lower on the northern horizon from those locations.
