Unknown Treasure Trove of Planets found Hiding in Dust


The Taurus Molecular Cloud, pictured here by ESA’s Herschel Space Observatory, is a star-forming region about 450 light-years away. The image frame covers roughly 14 by 16 light-years and shows the glow of cosmic dust in the interstellar material that pervades the cloud, revealing an intricate pattern of filaments dotted with a few compact, bright cores — the seeds of future stars.

The first unbiased survey of protoplanetary disks surrounding young stars in the Taurus star-forming region turned up a higher-than-expected number of disks with features suggesting nascent planets, according to a new study...

Just as the new calendar year begins, and with it a feeling of new beginnings, so this network of dust and gas shows a portion of sky where star birth is yet to take hold. This region is in Polaris, 490 light-years away. It was imaged by ESA’s Herschel space observatory in 2011; a colour composite is presented here. It shows several tens of tangled interstellar filaments. Such filaments can stretch for tens of light-years through space and can precede the onset of star formation, with newborn stars often found in the densest parts.
