Gum Nebula


Gum Nebula
Largest known emission nebula in terms of how much of the sky it occupies as seen from Earth, extending over about 35° in the southern constellations Puppis and Vela.

A complex of diffuse, glowing gas too faint to see with the unaided eye, it was discovered in the 1950s. It lies roughly 1,000 light-years from Earth and may be the remnant of an ancient supernova.

      largest known emission nebula in terms of angular diameter as seen from Earth, extending about 35° in the southern constellations Puppis and Vela. A complex of diffuse, glowing gas too faint to be seen with the unaided eye, it was discovered by the Australian-born astrophysicist Colin S. Gum, who published his findings in 1955. The Gum Nebula lies roughly 1,000 light-years from the Earth and may be the remnant of an ancient supernova—i.e., violently exploding star.
