Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Brown dust pillars in the Carina Nebula are shown. Many appear like a torch since their ends are lit up with starlight. Please see the explanation for more detailed information.

Stars Versus Dust in the Carina Nebula

Explanation: It's stars versus dust in the Carina Nebula and the stars are winning. More precisely, the energetic light and wind s from massive newly formed stars are evaporating and dispersing the dusty stellar nurseries in which they formed. Located in the Carina Nebula and inside a region known informally as Mystic Mountain , these pillars' appearance is dominated by opaque brown dust even though it is composed mostly of clear hydrogen gas. Even though some of the dust pillar s look like torches , their ends are not on fire -- rather, they are illuminated by nearby stars. About 7,500 light-years distant, the featured image was taken with the Hubble Space Telescope and highlights an interior region of Carina known as HH1066 which spans nearly a light year . Within a few million years, the stars will likely win out completely and the dust torches will completely evaporate .
