The Cone Nebula-Astro Picture of the Day
The Cone Nebula (NGC-2264)
The Cone Nebula is found in the constellation of Monoceros and it is a stellar nursery (star forming region) where new stars are born. It is an interstellar cloud of dust, hydrogen, helium and other ionized gases. These and other materials come closer to each other due to gravity over millions of years to form larger masses, which attract further matter, and eventually they become massive enough to form stars. The core of these stars have temperatures of over 10 million °C. The remaining materials are then believed to form planets, and other planetary system objects. We had seen the Orion Nebula in the constellation of Orion last winter during the Astro-camp . Some of you were there when we captured a beautiful colour picture of the Orion Nebula using the DSLR attached to the Telescope. The colours are due to the various gases present in the Nebula.
In the case of the Cone nebula radiation from hot stars off the top of the gaseous pillar lights up the cone structure. It is about 2700 light years from earth.
