Telescope sees birth of stars
Radiation and winds from a hot massive star sculpt clouds of cool gas and dust into ethereal mountains.
Inside the pillars, hundreds of new stars are forming thousands of light years from our planet.
Using its infra-red "eyes", the Spitzer Space Telescope has captured a spectacular view of stars forming inside the dark depths of interstellar clouds.
Visible-light images of the same region show dark towers fringed by halos of light.
The stars inside are hidden by dust. But infrared light coming from the stars can escape through the dust, giving astronomers a new view of our galaxy.
"We believe that the star clusters lighting up the tips of the pillars are essentially the offspring of the region`s single, massive star," said Dr Lori Allen from the Harvard-Smithsonian Center for Astrophysics in Cambridge, US.
"It appears that radiation and winds from the massive star triggered new stars to form."
Cassiopeia constellation
The image shows a region known as W5, in the Cassiopeia constellation, 7,000 light years away from the Earth.
It is a high-mass star-forming region, where a thick cloud of gas and dust later gives rise to families of stars.
Dr Allen believes the stars inside the pillars are a second generation of stars, triggered by the single massive star.
