Roughly 7,500 light-years away from Earth is a double star system calledEta Carinae. In 1838, one of the system’s two stars underwent anear-death experience astronomers dubbed the “Great Eruption,ö and fornearly two centuries, scientists have been watching the stunningaftermath of that event.
On Monday, researchers from NASA and the ESA released new photos of EtaCarinae captured by the Hubble telescope — and the most extravagantFourth of July firework display can’t hold a candle to this cosmic one.The new images are Hubble’s highest resolution photos of Eta Carinae,and they provide a remarkable view of the star system’s expanding gases,which glow in a holiday-appropriate red, white, and blue.
The cosmic fireworks aren’t just notable for their beauty, either,according to researcher Nathan Smith. “We had used Hubble for decades tostudy Eta Carinae in visible and infrared light, and we thought we had apretty full account of its ejected debris,ö Smith said in a pressrelease. “But this new ultraviolet-light image looks astonishinglydifferent, revealing gas we did not see in either visible-light orinfrared images.ö
