"A huge European Space Organisation survey has gathered more than a million
images of five stellar nurseries, revealing the secret lives of young stars in
the making.
“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, a University of Vienna astronomer and lead
author of the new study.
“This will allow us to understand the processes that transform gas and dust
into stars.”
The survey, called VISIONS has been undertaken by the VISTA telescope in Chile
using infrared to peer deep into molecular clouds.
“The dust obscures these young stars from our view, making them virtually
invisible to our eyes. Only at infrared wavelengths can we look deep into these
clouds, studying the stars in the making,” explains Alena Rottensteiner,
another University of Vienna astronomer.
The paper, published in the paper
Astronomy & Astrophysics looked at five
nearby stellar nurseries – in the constellations of Chamaeleon, Corona
Australis, Lupus, Ophiuchus, and Orion – for five years.
The VISION data provides scientists not only with more information on how these
proto-stars look, but also how they change over time – a type of cosmic dance
as they age."
