2010 Hubble Space Telescope Advent Calendar: Day 2

Image 2: This turbulent cosmic pinnacle lies within a stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation of Carina. Scorching radiation and fast winds (streams of charged particles) from super-hot newborn stars in the nebula are shaping and compressing the pillar, causing new stars to form within it. Streamers of hot ionised gas can be seen flowing off the ridges of the structure, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks. The denser parts of the pillar are resisting being eroded by radiation. Nestled inside this dense mountain are fledgling stars. Long streamers of gas can be seen shooting in opposite directions from the pedestal at the top of the image. Another pair of jets is visible at another peak near the centre of the image. These jets, (known as HH 901 and HH 902, respectively), are signposts for new star birth and are launched by swirling gas and dust discs around the young stars, which allow material to slowly accrete onto the stellar surfaces. Hubble's Wide Field Camera 3 observed the pillar on 1-2 February 2010. (NASA, ESA, M. Livio and the Hubble 20th Anniversary Team,STScI)
