Star: Eta Carina A+B
Combined Luminosity: (variable) 1 to 5 million x Sol
Type: Luminous Blue Variables
Distance from Sol: 9453 ly; galactic xyz coordinates 2858 -9010 -103

A peculiar, erratically fluctuating binary star, both elements of which are Luminous Blue Variables. One of the most luminous stellar objects of our Galaxy. The interaction between the two stars and their stellar winds cause wild fluctuations in their combined UV and X-Ray emissions. Sometimes Eta Carina is easily visible from the Inner Sphere, even with baseline human eyes; at other times it is much less bright. The star is located in the Carina OB1 stellar association, and is surrounded by the Homunculus Nebula, which has changed shape many times in the last 10 thousand years since it was first observed.

Fast explorer class probe ships are currently en route to the star, and the first of these have almost certainly arrived; however the confirmation message from the lead vessels has not yet arrived back in the Terragen Sphere yet. Long distance observation of this beacon star suggests that there are a number of quite advanced xenosophont vessels present in this location, possibly from HEEC1, or another less well-known civilisation. These vessels are probably studying the star in anticipation of its explosion as a supernova, likely to happen in the next two thousand years (depending on frame of reference).
