It first took place in the mid-19th century and the aftermath is still continuing to be observed today.
New footage shows how the explosion has expanded into space with staggering speeds of up to 4.5 million miles per hour.
In a statement, NASA officials explained: “During this event, Eta Carinae ejected between 10 and 45 times the mass of the sun. This material became a dense pair of spherical clouds of gas, now called the Homunculus Nebula, on opposite sides of the two stars.”
The Homunculus Nebula is the blue cloud visible in the video, while the growing bright orange ring shows how X-ray emissions have grown and expanded over time.
“The new movie of Chandra, plus a deep, summed image generated by adding the data together, reveal important hints about Eta Carinae’s volatile history,” the statement read.
“This includes the rapid expansion of the ring, and a previously-unknown faint shell of X-rays outside it.”
