Eta Carinae: The Great Eruption

Twenty-21 years of observations from the Chandra X-ray Observatory have been put together to make a film of Eta Carinae.

The movie traces the after-effects of an explosion so large we lack adjectives to convey its scale.

For 18 years in the mid-19th century, the leaderboard of brightest stars was upended when the previously faint star Eta carinae entered the charts.

It lies so far south that none of the era’s largest telescopes could see it.

It’s only in recent decades, when leading instruments were built high in the Andes and space telescopes became able to see the whole sky that astronomers have started to play catch-up.
