Interstellar Breeze


Date: 24 April 1998
Satellite: SOHO
Depicts: Intersteller wind

An unprecedented chart shows the true direction and apparent speed of a breeze of atoms, mainly hydrogen, that comes from the stars and blows right through the Solar System. In the solar spacecraft SOHO, built by the European Space Agency, the SWAN instrument detects a characteristic ultraviolet glow filling the sky, coming from the hydrogen atoms. Small shifts in the ultraviolet wavelength reveal the speed of the breeze.
