Images of interstellar material from the Herschel Space Observatory, taken with the SPIRE and PACS cameras:
The two instruments have imaged an area of about 2 x 2 degrees (about 16 times as big as the size of the Moon as seen from Earth), revealing an extremely rich reservoir of cold material in the Galactic Plane which is seen to be in a previously unsuspected state of turmoil. The interstellar material is condensing in a continuous and interconnected maze of filaments and strings of newly forming stars in all stages of development, unveiling a tireless Galaxy constantly forging new generations of stars. We see an intricate network of filamentary structures with surprising features indicative of a chain of near-simultaneous star-formation events, glittering rather like beads of water on a string in the sunlight.
