SUMMARY
Eta Carinae is confirmed to be approximately 8,500 light-years away, which is 25-30% farther than earlier estimates. This conclusion is based on new data derived from Gaia parallaxes of stars associated with Eta Carinae. Additionally, the star system is identified as a potential gamma-ray burst candidate, emphasizing the significance of its distance in relation to its luminosity and potential impact on Earth.
