Eta Carinae's Dramatic Brightening: A Stellar Event
Imagine a star that used to be quiet but then suddenly became super bright, like a firework!
That's kind of what happened with Eta Carinae, a pair of stars.
It wasn't always so noticeable, but one day it lit up like the second brightest thing in the sky, after the dog star Sirius.
Over time, the star's brightness faded away.
It is currently a very interesting subject for scientists.
Eta Carinae is a binary star system.
Eta Carinae was once faint and unremarkable.
In April 1843, Eta Carinae brightened dramatically.
The star became the second brightest in the sky.
Eta Carinae dimmed steadily over the following decades.
