Astronomers have monitored the Eta Carinae binary system for more than two decades. It has been prone to violent outbursts, including an episode in the 1840s during which ejected material formed the bipolar bubbles seen here. Now, using Hubble’s Wide Field Camera 3 (WFC3) instrument to probe the nebula in ultraviolet light, they have uncovered the glow of magnesium embedded in warm gas (shown in blue) in places they had not seen it before. The luminous magnesium resides in the space between the dusty bipolar bubbles and the outer shock-heated nitrogen-rich filaments (shown in red). The streaks visible in the blue region outside the lower-left lobe are a striking feature of the image. These streaks are created when the star’s light rays poke through the dust clumps scattered along the bubble’s surface. Wherever the ultraviolet light strikes the dense dust, it leaves a long, thin shadow that extends beyond the lobe into the surrounding gas. Image credit: NASA / ESA / Hubble / N.

This 3D spectro-imaging data cube was produced using software called OsrsVol, short for OSIRIS-Volume Display; Ciurlo et al developed this custom volume rendering tool to separate G3, G4, and G5 from the background emission; once the 3D analysis was performed, the astronomers could clearly distinguish the G-objects, which allowed them to follow their movement and see how they behave around the supermassive black hole.
