Title: Eta Carinae: A Star With a Past…and No Future

 Abstract: Eta Carinae is too far south to be observed north of Cairo, Egypt, making it unobservable to astronomers before the renaissance. It was recorded by some early southern explorers, including Edmund Halley. In the 1840’s, it increased its luminosity by 10x. At its peak, it radiated energy at a rate 20 million times the Sun’s. Modern instrumentation have revealed much that was hidden and presented more mysteries. Once thing is certain: at only three million years old, Eta’s life is nearly over.
