Astromony The Cone Nebula from Hubble
Stars are forming in the gigantic dust pillar called the
Cone Nebula. Cones, pillars, and majestic flowing shapes abound in stellar
nurseries where natal clouds of gas and dust are buffeted by energetic winds
from newborn stars. The Cone Nebula, a well-known example, lies within the
bright galactic star-forming region NGC 2264. The Cone was captured in
unprecedented detail in this close-up composite of several observations from
the Earth-orbiting Hubble Space Telescope.
While the Cone Nebula, about 2,500
light-years away in Monoceros, is around 7 light-years long, the region
pictured here surrounding the cone’s blunted head is a mere 2.5 light-years
across. In our neck of the galaxy that distance is just over half way from the
Sun to its nearest stellar neighbor, the Alpha Centauri star system
. The
massive star NGC 2264 IRS, seen by Hubble’s infrared camera in 1997, is the
likely source of the wind sculpting the Cone Nebula and lies off the top of the
image. The Cone Nebula’s reddish veil is produced by glowing hydrogen gas.
