Herschel’s view of new stars and molecular clouds
الشرح: This image shows the Westerhout 3, 4 and 5 star formation regions. This area has huge amounts of gas and dust. This gas and dust hides the physical processes going on in this region from studies using visible light. This image was taken in infrared light by the Herschel Space Observatory. This infrared light allowed Herschel to see deep into these star forming regions.
In Westerhout 3, 4 and 5, huge, cold clouds of molecular hydrogen have collapsed into dense knots and filaments. Within these new structures the gas is dense and cold enough for it to collapse and form stars. These new stars give off powerful winds of charged particles, like stronger versions of the solar wind our sun gives off. These winds have combined to blow massive bubbles in the surrounding gas and dust. These are visible as the large darker voids in the image.

WISE Survey Capturing the Whole Sky in Infrared Light
الشرح: This image presents the entire sky mapped in infrared light from space by the WISE satellite. While dust in the plane of the Milky Way blocks visible light, obscuring the heart of our Galaxy, infrared light passes through the dust. The most prominent feature is the broad, bright band running horizontally through the centre — this is the plane of our Milky Way galaxy. Numerous brighter knots and patches appear above and below the band, marking regions of active star formation and nearby galaxies.
Such a dataset is a classic example of an astronomical survey, in which large portions of the sky is scanned to build a comprehensive catalogue of cosmic sources. The WISE satellite operated in space, allowing it to study parts of the infrared spectrum blocked by Earth's atmosphere.
