Astronomers Watch Century-Old Broadcast of Powerful Stellar Eruption |
Astronomers are watching a delayed broadcast of a spectacular outburst from the unstable, behemoth double-star system Eta Carinae, an event initially seen on Earth nearly 170 years ago.
Dubbed the “Great Eruption,” the outburst first caught the attention of sky watchers in 1837 and was observed through 1858. But astronomers didn’t have sophisticated science instruments to accurately record the star system’s petulant activity.
Luckily for today’s astronomers, some of the light from the eruption took an indirect path to Earth and is just arriving now, providing an opportunity to analyze the outburst in detail. The wayward light was heading in a different direction, away from our planet, when it bounced off dust clouds lingering far from the turbulent stars and was rerouted to Earth, an effect called a “light echo.” Because of its longer path, the light reached Earth 170 years later than the light that arrived directly. continue reading
