PUFFINS (Polarimetry in the Ultraviolet to Find Features in INterStellar dust) is a low-Earth orbit small satellite (SmallSat) mission hosting a specialized 10-inch ultraviolet space telescope designed to observe and measure the polarization of UV starlight passing through the interstellar medium.
Revives ultraviolet spectropolarimetry after nearly three decades, measuring the polarisation of starlight across different UV wavelengths to study interstellar dust properties.
Targets interstellar dust particles smaller than 50 nanometres, which are difficult to characterise using conventional optical and infrared observations.

What it is?
PUFFINS (Polarimetry in the Ultraviolet to Find Features in INterStellar dust) is a low-Earth orbit small satellite (SmallSat) mission hosting a specialized 10-inch ultraviolet space telescope designed to observe and measure the polarization of UV starlight passing through the interstellar medium.
Organisation: Funded by NASA’s Astrophysics Pioneers programme, PUFFINS is led by the University of Arizona’s Steward Observatory, in collaboration with the McDonald Observatory, University of Texas.
Aim: To investigate the composition, structure, and magnetic alignment of interstellar dust grains, understanding their influence on the formation and evolution of stars and planets.
Key Features of PUFFINS:
Space-Based UV Spectropolarimetry : Revives ultraviolet spectropolarimetry after nearly three decades, measuring the polarisation of starlight across different UV wavelengths to study interstellar dust properties.

Mapping Interstellar Magnetic Fields : Examines how elongated dust grains align with the Milky Way’s magnetic field, using changes in starlight polarisation to investigate galactic magnetic structures.
Examines how elongated dust grains align with the Milky Way’s magnetic field, using changes in starlight polarisation to investigate galactic magnetic structures. Observing Diverse Galactic Environments: Plans to study at least 70 distant stars across stellar nurseries, reflection nebulae, and the Magellanic Clouds to examine dust behaviour.
