This is another mystery not yet solved, however most astronomers support the binary hypothesis.

In 2007, the star had a visual magnitude of 5 and was once again visible to the naked eye.After the Great Eruption, some of the light from the star headed directly toward Earth, and in all other directions, but some of it also reflected off the nearby dust clouds and took a detour. Eta Carinae is one of the most massive binary star systems known, lying at a distance of about 7,500 light years from Earth.The smaller star has about 30 solar masses and may be up to a million times more luminous than the Sun.
However, observers in southern latitudes will see quite a spectacle in the sky, as Eta Carinae is one of the most massive stars in the Milky Way and the supernova event will be a very bright one. The field of view is approximately 4.7 x 4.9 degrees. Eta Carinae suffered a giant outburst about 150 years ago, when it became one of the brightest stars in the southern sky. In the first decades of the century, it became brighter and brighter, until, by April 1843, it was the second brightest star in the sky, outshone only by Sirius (which is almost a thousand times closer to Earth). Sebastián Piñera, President of Chile, aided in the capturing of this image during his June 2012 visit to the site.The NACO near-infrared adaptive optics instrument on ESO's VLT produced an unbelievable amount of detail in this new image of Eta Carinae and the lobes of material around it called the Homunculus Nebula.
Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw - astronomically speaking - from Earth at a distance of only about 7,500 light years. Somehow The map shows stars visible to the naked eye and delineates the nebula with a green square — it is quite bright and can be seen with small telescopes.A new perspective of the field around the Wolf-Rayet star WR 22 in the Carina Nebula combined with a previously imaged section of the Eta Carinae star, a composite of images from the Wild Field Imager from ESO's La Silla Observatory in Chile.Taken from ESO's Paranal Observatory in Chile, the photographer captured so many amazing astronomical objects. Other similar events have been seen in other galaxies in the last century, including SN 1961v in NGC 1058 in This image is a colour composite made from exposures from the Digitized Sky Survey 2 (DSS2). If the explosion does cause us some damage, it will be to the upper atmosphere and the ozone layer. The young O3 class star HD 93129 A is one of the brightest stars in the galaxy that is still on the main sequence, and with a luminosity equivalent to 3,000,000 Suns, is very nearly as bright as Eta Carinae, but this is not obvious in the photo due to obscuring nebulosities. This phenomenon is called a light echo. Satellites, spacecraft, and astronauts could be affected.
Trumpler 16 (lower left) is an open cluster that contains the luminous, massive blue variable Eta Carinae, one of the brightest stars in the galaxy, possibly as much as 120 times the mass of the Sun, and emitting the light of 4,000,000 Suns. Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural LASER light.

Weigelt See the highest-resolution views yet of the explosive star system Eta Carinae, which is 7,500 light-years from Earth in the constellation Carina.
This spectacular panoramic view combines a new image of the field around the Wolf–Rayet star WR 22 in the Carina Nebula (right) with an earlier picture of the region around the unique star Eta Carinae in the heart of … The supernova impostor event itself, of course, occurred about 7,500 years ago. The star has continued to vary in brightness ever since, and while it is once again visible to the naked eye on a dark night, it has never again come close to its peak of 1843. Images taken through red and near-ultraviolet filters were subsequently combined to produce the color image shown. Stunningly centered in the image Carina Nebula burns with a red severity.The Very Large Telescope delivers the Carina Nebula, a sensational specimen of a star factory, in phenomenal detail. Trumpler 14 (in the centre) contains the huge double star HD 93129 A/B. Many previously hidden features, scattered across a spectacular celestial landscape of gas, dust and young stars, have emerged.
This image , taken in 1996, brought out new details in the unusual nebula that surrounds this rogue star . At least some of the echo of the event observed in 1843 reached us only recently. Though the star released as much visible light as a supernova explosion, it survived the outburst. The Eta Carinae star system does not lack for superlatives. It is a very rare hypergiant star with a mass more than a hundred times that of the sun.
