ESA's Herschel Space Observatory is helping unravel the mystery of where cosmic dust comes from. Thanks to the resolution and sensitivity of Herschel, astronomers have been able to detect cosmic dust from a supernovae, adding weight to the theory that these cosmic fireworks are responsible for its creation.

 | Astronomers have unveiled an unprecedented new atlas of the inner regions of the Milky Way, our home galaxy, peppered with thousands of previously undiscovered dense knots of cold cosmic dust -- the potential birthplaces of new stars. Made using observations from the APEX telescope in Chile, this survey is the largest map of cold dust so far, and will prove an invaluable map for observations made with the forthcoming ALMA telescope, as well as the recently launched ESA Herschel space telescope. ...> Full Article |
 | The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team of colleagues. ...> Full Article |
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust.

Astronomers have found evidence to suggest that during the early stages of the Universe, cosmic dust -- the building block for the formation of planets and life throughout the cosmos -- was partially created by the gradual death of carbon stars, dispelling theories that it comes solely from stars that have exploded. They observed dust forming around a dying star in a nearby galaxy, similar to the primitive galaxies that formed soon after the big bang, giving them a fascinating glimpse back in time.

 | The first definitive evidence of cosmic dust, important in building planets like our Earth and ultimately ourselves, has been found in the remains of a massive star explosion 11,000 light years away in our own Galaxy. ...> Full Article |
