The week 18-22 September 2017, ESA and NASA jointly celebrated the legacy of the Herschel Space Observatory with a series of web articles, new images, and videos on various key areas where Herschel has made major contributions and on the legacy of the Herschel mission. Visit sci.esa.int/herschel-week for more details.
Delving deep into the history of our cosmos, the Herschel Space Observatory scrutinised hundreds of thousands of star-forming galaxies, peering back in time to when the Universe was less than one billion years old.
Surveying the sky for almost four years to observe the glow of cold cosmic dust embedded in interstellar clouds of gas, the Herschel Space Observatory has provided astronomers with an unprecedented glimpse into the stellar cradles of our Galaxy
Cosmic Water Trail
During almost four years of observing the cosmos, the Herschel Space Observatory traced out the presence of water.
Herschel Legacy: Science Data, Discoveries & the People
The bubbles and wisps portrayed in this image by ESA’s Herschel Space Observatory reveal great turmoil in the W3/W4/W5 complex of molecular clouds and star-forming regions. Located over 6000 light-years away, in the northern constellation Cassiopeia, it is one of the best regions in which to study the life and death of massive stars in our Milky Way galaxy.
