Astrophysics: Echo from an ancient supernova
Andrea Pastorello1 & Ferdinando Patat2
Abstract
Light reflected off a dust cloud in the vicinity of the relic of Tycho Brahe's supernova, whose light first swept past Earth more than four centuries ago, literally sheds light on the nature of this cosmic explosion.
The occurrence of a supernova in our Galaxy is a rare event — only six such supernovae were registered during the past millennium1. Although their remnants have been extensively studied, the nature of the original explosions is the subject of debate.
- Andrea Pastorello is at the Astrophysics Research Centre, School of Mathematics and Physics, Queen's University Belfast, Belfast BT7 1NN, UK.
