Overview

Other Herschel First Science Stories

ESA's Herschel infrared space observatory is changing the way scientists view the Universe. From nearby celestial objects to distant ones, from the smallest molecules to the largest galaxies, Herschel is revealing new details about how the Universe behaves.

Herschel takes the temperature of an interstellar cloud

Herschel takes the temperature of an interstellar cloud

The unrivalled ability of ESA’s Herschel infrared space observatory to discern detail in celestial objects has been used to take the temperature across a star-forming cloud. For the first time, an entire cloud has had its temperature mapped from the centre to the edge.

Tracing the Milky Way’s hidden reservoirs of gas

ESA’s Herschel infrared space observatory has found that hydrogen fluoride molecules are everywhere in interstellar gas clouds. They betray hidden reservoirs of gas, and may ultimately become a key tracer of star-forming gas clouds in distant galaxies.

Herschel resolves the cosmic infrared fog

Herschel resolves the cosmic infrared fog

ESA’s Herschel space telescope has discovered that previously unseen distant galaxies are responsible for a cosmic fog of infrared radiation. The galaxies are some of the faintest and furthest objects seen by Herschel, and open a new window on the birth of stars in the early Universe.
