14 DAY TRIAL // This image shows what the largest star in the Eta Carinae binary system might look like when it blows up, in the near (astronomical) future. This may translate into a few million years from now, but that is a very brief time in universal terms.
The largest star in the system has already experienced a massive explosion in 1843, but managed to survive it. Astronomers say that it is becoming very unstable. Due to its massive size, it only lives for a fraction of the time a star the size and mass of the Sun does (a few hundred million years as opposed to 10+ billion years).
When the Eta Carinae star blows up, it will produce a massive glow in the sky. Residual light will become visible even during the day, and will most likely persist for a long time, maybe even more than a year. Astronomers of the future will certainly have a field day with this event.
