The cosmic optical background (COB) is the visible light emitted by all sources outside of the Milky Way. This faint glow of light, which can only be observed using very precise and sophisticated telescopes, could help astrophysics ...
Measurements by ESA's long-serving twin missions, Mars Express and Venus Express, have captured the dance between the intensity of high-energy cosmic rays and the influence of the sun's activity across our inner solar system.
