night-of-the-comet

Aurora, Luna and comet.

Shortly after sunset, whose glow is still visible in the background, Ingólfur Bjargmundsson snapped this image of the Aurora Borealis and comet Panstarrs. The comet is visible as a smudge above the sunset and below the right hand streamer of glowing charged particles that channel the energy of the solar wind down towards the surface. Barring the stars all the light in this image derives from Sol.

This image is part of the Astronomy Photographer of the Year exhibition at the Royal Observatory in Greenwich, London.
