Hubble photos showcase two faces of a luminous blue variable


Two views of AG Carinae as imaged by the Hubble Space Telescope. On the left, ionised hydroden and nitrogen in an increasing shell across the star are proven in purple hues whereas dusty clumps and bubbles formed by the solar wind are proven in blue on the fitting.

Reprising the Hubble Space Telescope’s thirty first anniversary picture, the venture group has launched two views of the luminous blue variable AG Carinae, a large star embedded in a 5-light-year-wide shell of increasing fuel and dust ensuing from a number of eruptions over the previous 10,000 years because the star burns by way of its nuclear gasoline. In one view, ionised hydrogen and nitrogen emissions within the increasing shell of fuel blown off earlier are proven in purple whereas dust shining in mirrored mild is proven in blue. AG Carinae is repeatedly shedding mass, inflicting it to contract, warmth again up and explosively eject materials into surrounding space. The fuel (proven in purple) making up the nebula surrounding the star is transferring outward at some 43 miles per second. Dust within the shell (proven in blue) kinds clumps, bubbles and filaments, formed by the high-speed stellar wind. Full-frame views highlighting each features of AG Carinae are proven beneath:
