Galaxy accreting cold gas, artwork. These filaments of cold intergalactic gas provide a continuous flow of raw material for star formation in the galaxy at centre. This is an area of active research in astrophysics, with several missions that could provide evidence for this process. One such mission is the Herschel Space Observatory (HSO), a space telescope launched in 2009 that collects long-wavelength infrared radiation from some of the coolest and most distant objects in the Universe, enabling studies of star formation and galactic evolution.
