Herschel stares into Aquila

Scientists have gathered in Madrid this week to discuss for the first time the data they have received from the new infrared telescope Herschel that was launched in May of this year. Some fantastic images have been produced as part of the first observing programmes, like the one above of an active star forming region in the constellation Aquila. The region was known as a ‘dark cloud’ – meaning that dust was blocking any visible or near-infrared radiation coming from its interior. Until Herschel came along, and switched on the lights. Observing at longer infrared wavelengths, the telescope is sensitive to radiation from cooler and dusty material, allowing it to peer into the cloud’s interior. The image, created from data from two of Herschel’s images, PACS and SPIRE, shows up to 700 dense pockets of cold and dusty material that may eventually condense into stars; around 100 of them have progressed to the protostellar stage where they begin to resemble a young forming star.

ESA has launched a new site to showcase the Herschel images. A little sparsely populated so far, but the first postings are very promising indeed.
