Lyra — The Harp

A small, compact constellation that punches far above its size: home to brilliant Vega, the famous Ring Nebula, a quadruple "double-double" star, and the variable star that helped astronomers measure the cosmos.

The Lyre of Orpheus

Small, but unforgettable

Lyra represents the lyre — a small harp — of Orpheus, the legendary musician of Greek myth whose playing could charm stones and tame wild beasts. After his death, the gods placed his instrument in the sky. It is one of the smaller constellations, but it sits in a glorious stretch of the summer Milky Way and anchors the top corner of the Summer Triangle.

The constellation's main pattern is easy to learn: brilliant Vega at one corner, with a small, neat parallelogram of fainter stars hanging just below it. That little parallelogram is where the Harp's deep-sky treasures hide.

Observing Note

Lyra is the rare constellation where nearly every named star or object is worth stopping on. For its size, few patches of the summer sky are richer per square degree.

Stars of the Harp

Key Stars

  • α Lyr — Vega. Magnitude 0.03 — the fifth-brightest star in the night sky and once the zero-point of the entire brightness scale. A hot, blue-white star 25 light-years away, and a corner of the Summer Triangle. (See its full profile.)
  • β Lyr — Sheliak. The prototype of the Beta Lyrae variables — a pair of stars so close they are distorted into egg shapes and pour gas onto one another, eclipsing each other every ~13 days in a visible brightness cycle.
  • γ Lyr — Sulafat. A blue-white giant marking another corner of the Harp's parallelogram, the brightest "fixed" star in the figure after Vega.
  • ε Lyr — the Double Double. A famous multiple star: binoculars split it into two stars, and a telescope splits each of those into two again — four stars in all. A classic test of a telescope's sharpness.
  • RR Lyrae. The prototype of an entire class of pulsating variable stars used as standard candles to measure distances across the Milky Way and beyond.
The Ring Nebula — M57

The Harp's crown jewel

Lyra's most celebrated object is the Ring Nebula (Messier 57) — a planetary nebula sitting almost exactly midway between the stars Sheliak and Sulafat in the bottom of the parallelogram. It is the glowing shell of gas cast off by a dying Sun-like star, seen as a near-perfect smoke ring roughly 2,500 light-years away.

The Ring is one of the easiest planetary nebulae to find and a showpiece in even a modest telescope. It has its own dedicated page on this site, with Webb and Hubble imagery and the story of its tangled discovery in 1779.

A Modern Footnote

Where Kepler hunted for worlds

Lyra has a special place in the search for planets beyond the Solar System. NASA's Kepler Space Telescope stared at a single patch of sky straddling Lyra and Cygnus for years, monitoring some 150,000 stars for the tiny dips in brightness caused by transiting planets. That one fixed field of view — anchored near the Harp — produced thousands of confirmed exoplanets and transformed our understanding of how common planets are.

Observing Guide

Finding and observing Lyra

Lyra is trivially easy to locate: just find Vega, which is often the first brilliant star to appear high overhead on summer evenings. The small parallelogram dangling beneath it is the body of the Harp.

Equipment Guide

Naked eye: Vega and the parallelogram; the Summer Triangle.
50mm binoculars: Epsilon Lyrae splits into two stars; M56 appears as a faint glow.
6-inch telescope: The Ring Nebula shows clearly as a tiny smoke ring; the Double Double resolves into four stars.
Best season: June through October evenings in the Northern Hemisphere.

The Myth of Orpheus

The harp that charmed the underworld

Lyra is the lyre of Orpheus, the greatest musician of Greek myth. His playing stilled rivers, leaned trees toward him, and quieted wild animals on the hillside. When his wife Eurydice died of a snakebite, Orpheus walked down into the underworld and played until Hades himself wept and agreed to release her, on one condition: Orpheus must lead her back to the light and never once look behind him. A few steps from the surface, doubt won. He turned to be sure she still followed, and she slipped back into the dark for good.

Orpheus never recovered. He met a violent end, and his lyre fell into a river, still sounding notes as it drifted. The Muses gathered the instrument and asked Zeus to set it in the sky, where Vega now burns at its head. The harp that could move the dead became a fixture of the summer night.

Lyra is the small harp of the summer sky — a handful of stars carrying Orpheus's music, a dying star's perfect ring, and the field where we first learned how many other worlds are out there. Proof that the richest things in the heavens don't need to be the largest.
