"Captivating Time-lapse Reveals Ancient Stellar Explosion in Stunning Detail"

A timelapse video has been created using 20 years of data from the Chandra X-ray Observatory, showcasing the dynamic environment surrounding the Eta Carinae star system. The video reveals the expansion of the X-ray shell surrounding the system, believed to be remnants of the "Great Eruption" that occurred in the 1840s. The eruption, likely caused by a stellar merger, ejected massive amounts of material and formed the Homunculus nebula. The timelapse provides a unique glimpse into the cosmic activity of the binary star system.

"NASA's Chandra Unveils Secrets of 1840s Great Eruption"

NASA's Chandra X-ray Observatory has provided new insights into the Great Eruption of Eta Carinae, a stellar explosion witnessed on Earth in the 1840s. Using data spanning two decades, astronomers created a movie that shows the expansion of the eruption at speeds up to 4.5 million miles per hour. The observations reveal a faint shell of X-rays outside the Homunculus Nebula, suggesting a common origin. The study also suggests that the Great Eruption consisted of two explosions, with the first ejection of low-density gas creating the X-ray blast wave, followed by the slower ejection of dense gas forming the Homunculus Nebula.
