A Supernova You Can Hold In Your Hand

In Previous century, a massive binary star system went supernova, emitting at least 10 times the mass of our Sun into the cosmos. NASA researchers have now generated the first hi-res model of the increasing cloud formed by this iconic eruption. Through the eruption, which happened between 1838 and 1845 (at least from our viewpoint in the Hubble Bubble; the entity is situated about 7,500 light-years away), a gigantic gaseous shell was expelled into space. The subsequent explosion, what we call Eta Carinae, went on to develop the second-brightest star in our sky. The discharged area now procedures a twin-lobed and dust-filled cloud acknowledged as the Homunculus Nebula. The outstanding stellar object is presently about one light-year long as it stays to swell at more than 1.3 mph (2.1 million km/h).

The fresh model was assembled using new interpretations made by the European Southern Observatory's Very Large Telescope (VLT) and its X-Shooter spectrograph over two nights in March 2012. The group imaged near-infrared, ultraviolet and visible wavelengths along 92 distinct bands across the nebula; it's reflected to be the most complete spectral map to date. A software platform called "Shape" was used to generate the 3D modeling.
