This finding indicates that the nebula likely still carries an impression from the period around the time of the Great Eruption, when the two stars came to their closest approach.The 3D model of the Homunculus Nebula has been converted to a format that can be used by 3-D printers, and is available to anyone with access to a 3-D printer, along with the published study.Theodore Gull, Goddard astrophysicist and co-author of the paper, said, “While 3-D-printed models will make a terrific visualization tool for anyone interested in astronomy, I see them as particularly valuable for the blind, who now will be able to compare embossed astronomical images with a scientifically accurate representation of the real thing.”Eta Carinae was believed to be a single star until 2005, when evidence confirmed that it was in fact a binary system.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 nebula (left). This shell, now roughly a light year in length, forms the famous twin-lobed Homunculus Nebula.
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. 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.
NY 10036. New York, Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, it is also extremely volatile and is expected …
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. Scientists call these outbursts supernova impostor events, because they appear similar to supernovae but stop just short of destroying their star. The picture was created from images taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. Eta Carinae was a 2nd magnitude star by then. Trumpler 14 (in the centre) contains the huge double star HD 93129 A/B. If the explosion does cause us some damage, it will be to the upper atmosphere and the ozone layer. Both stars will reach the end of their life cycle in supernova or hypernova explosions in the relatively near future.The Carina Nebula is a large bright nebula that surrounds several clusters of stars. It contains two of the most massive and luminous stars in our Milky Way galaxy, Eta Carinae and HD 93129A. By continuing to use the site, you agree to the use of cookies. Is Eta Carinae a binary or single star? Located 7500 light years away, the nebula itself spans some 260 light years across, about 7 times the size of the The reflection nebula surrounding Eta Carinae is known as the Homunculus Nebula and is part of the larger The combined bolometric luminosity of the Eta Carinae system is more than 5 million times that of the Sun. Their stellar winds interact even more dramatically during this period (called periastron) and the faster wind, emanating from the smaller star in the binary sytem, carves a tunnel through the denser wind of the larger star. Image: Nathan Smith (University of California, Berkeley), and NASAJose Groh, an astronomer at Geneva University in Switzerland, said, “One of the questions we set out to answer with this study is whether the Homunculus contains any imprint of the star’s binary nature, since previous efforts to explain its shape have assumed that both lobes were more or less identical and symmetric around their long axis. Eta Carinae was observed by Hubble in September 1995 with the Wide Field and Planetary Camera 2 (WFPC2).
The model has alo helped identify new features of the nebula, including large, deep trenches around each lobe, irregular divots on the side facing away from Earth, and arm-like protrusions from each lobe near the dust skirt that can be seen near the nebula’s centre in visible light.A huge, billowing pair of gas and dust clouds are captured in this stunning NASA Hubble Space Telescope image of the supermassive star Eta Carinae.
