The only other important optical emission is due to the presence of oxygen - these stars within it. The nebula is about 8800 light years away and lies in the Sagittarius Arm. The visual light curve, 1595–2000. Eta Carinae (η Carinae or η Car) is a superbright hypergiant star in the constellation Carina, about 7,500 to 8,000 light-years from the Sun. Much of this radiation is absorbed by the primary stellar wind. xmlns:xsl='http://www.w3.org/1999/XSL/Transform'">. The best space images of 2019. Astron and Astrophys, 94, 12. then it would be about five million times brighter than the Sun. A hot supergiant of about 30 solar masses is in orbit around the primary. Eta Carinae's chief significance for astrophysics is its giant eruption, which was observed around 1843. Eta Carinae is one of the most remarkable stars in the heavens. The system contains at least two stars, of which the primary is a luminous blue variable (LBV) that initially had around 150 solar masses, of which it has lost at least 30. probably neighbouring nebulae not connected to the Eta Carinae nebula.
One remarkable aspect of Eta Carinae is its changing brightness. were ejected during the 1848 eruption. The strongest emission comes from the red hydrogen-alpha line
Because it is clumpy on such small scales, and has such a well defined edge, the nebula is probably a thin and well defined shell of material, rather than a filled volume. When hydrogen glows, it emits bright red light. Since, its brightness has varied in a most remarkable way: In 1730, its brightness reached mag 2, and again fell to mag 4 in about 1782.

An enormous thick red nebula surrounding Eta Carinae makes it impossible to see this companion optically, but the dumbell-shaped gas cloud is formed by two stars.[1]. Until recently, Eta Carinae was thought to be the most massive single star, but in 2005 it was proved to be a binary system. The Kash A. At the heart of the Eta Carinae nebula is one of the most remarkable stars known. The Eta Carinae nebula is classified as NGC 3372, it covers about three degrees of the sky which at a distance of 8800 light years corresponds to a diameter of about 460 light years. Although it is a large distance from us, the central region of this This stellar system is currently one of the most massive that can be studied in detail. (and possibly more distant) nebula around NGC 3503. Small knots and filaments trace the locations of other shock fronts within the nebula. The name NGC 3503 however, only nebula', a dark nebula with a keyhole shape, although it seems likely that the keyhole Probing the Last Gasps of Doomed Star Eta Carinae The signature balloon-shaped clouds of gas blown from a pair of massive stars called Eta Carinae have tantalized astronomers for decades.

Below is a map of the star clusters and nebulae in the region of the Eta Carinae Eta Carinae became the second brightest star in the sky between 11 and 14 March 1843 before fading well below naked eye visibility. It has brightened since about 1940, peaking above magnitude 4.5 in 2014. It was a 'supernova impostor' or 'failed supernova'. century and it is now at the limit of naked-eye visibility. They are assumed to be near or over the Eddington limit. This ridge is in fact part of a "cap" of material located to the southwest and behind the star. nebula is bright enough to see with the naked eye (although only from equatorial and southern latitudes on Earth). Trumpler It is currently classified as a luminous blue variable (LBV) binary star due to peculiarities in its pattern of brightening and dimming. Are you a journalist?
