Eta Carinae: Observations in UV Light Uncover Magnesium Embedded in Warm Gas

Summary[edit]

Description
English: Giant Star Yields New Clues About Turbulent Life

This Hubble Space Telescope image of the giant, petulant star Eta Carinae is yielding new surprises.

Telescopes such as Hubble have monitored the super-massive star for more than two decades. The star, the largest member of a double-star system, 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 to probe the nebula in ultraviolet light, astronomers 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 in 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.

Eta Carinae resides 7,500 light-years away.
