Let there be light/rev II

Using ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of stellar birth.

“In these images we can detect even the faintest sources of light, like stars far less massive than the Sun, revealing objects that no one has ever seen before,” says Stefan Meingast, an astronomer at the University of Vienna in Austria and lead author of the new study published today in Astronomy & Astrophysics. “This will allow us to understand the processes that transform gas and dust into stars.”

Stars form when clouds of gas and dust collapse under their own gravity, but the details of how this happens are not fully understood. How many stars are born out of a cloud? How massive are they? How many stars will also have planets?

Questions, questions, never-ending in a reality we will never fully understand. 

This image shows the IRAS 11051-7706 object in the Chamaeleon constellation. New stars are born in the colourful clouds of gas and dust seen here. The infrared observations underlying the image reveal new details in the star-forming regions that are usually obscured by the clouds of dust. The image was produced with data collected by the VIRCAM instrument, which is attached to the VISTA telescope at ESO’s Paranal Observatory in Chile. The observations were done as part of the VISIONS survey, which will allow astronomers to better understand how stars form in these dust-enshrouded regions. Credit: ESO/Meingast et al.

Gotta do one more. :)

A dark cloud of cosmic dust snakes across this spectacular image, illuminated by the brilliant light of new stars. This dense cloud is a star-forming region called Lupus 3, where dazzlingly hot stars are born from collapsing masses of gas and dust. This image was created from images taken using the VLT Survey Telescope and the MPG/ESO 2.2-metre telescope.  Credit: ESO/R. Colombari

As stated before, we are but a dust mote in god's eye.
