description Jones-Emberson 1 Overview

Jones-Emberson 1, commonly known as the Headphone Nebula, is a large and exceptionally faint planetary nebula located in the northern constellation of Lynx. It was discovered in 1939 by Rebecca Jones and Richard Emberson on photographic plates taken at the Harvard Observatory. Spanning about five arcminutes in apparent size, the nebula is estimated to be roughly 1,600 light-years from Earth. It is primarily of interest to amateur and professional astronomers who use specialized astrophotography equipment to observe its low surface brightness.

help Jones-Emberson 1 FAQ

Where is the Headphone Nebula located?

Jones-Emberson 1, commonly known as the Headphone Nebula, is located in the northern constellation of Lynx. It is an exceptionally faint planetary nebula positioned far away from the galactic plane. Its exact distance remains somewhat uncertain among astronomers.

Who discovered Jones-Emberson 1?

The nebula was discovered in 1939 by Rebecca Jones and Richard Emberson. They identified the unusually faint object on photographic plates taken at the Harvard Observatory. It was subsequently named in honor of the two astronomers.

Why is Jones-Emberson 1 called the Headphone Nebula?

It has been given the informal moniker "Headphone Nebula" because its visual shape resembles a pair of over-ear headphones. The central star is surrounded by two faint, symmetrical lobes of gas. This shape becomes apparent in long-exposure astrophotography.

How hard is it to observe the Headphone Nebula?

Jones-Emberson 1 is notoriously difficult to observe because it is an extremely large and faint planetary nebula. It requires very dark skies, a large aperture telescope, and specialized filters like an OIII filter to be seen visually. Most amateur astronomers can only capture it through long-exposure imaging.
