On October 6, 2016, NASA’s Hubble Telescope revealed images of a dying star which shoot with fireballs in the cosmos. Amazing images, you think, right? A star which is situated 1,200 light-years away from Earth is sending balls of fire through space at high speed. Specialists claim that the speed of the fire globs is so high that they could traverse the distance from our moon to Terra in less than thirty minutes. Are we somehow in danger? Could these fire globs hit our planet?
- NASA’s Hubble Telecope captures images of a dying star.
- Scientists were able to analyze planetary nebulae even more.
The study was recently published in The Astrophysical Journal. Astronomers claim that they are familiar with stars like V Hydrae star, but they have never seen shooting fire globs traversing the atmosphere. The V Hydrae is a star which approaches to the end, being soon engulfed by darkness. It was estimated that approximately half of its mass was already shut in outer space, consuming its energy and brightness.
The nuclear balls are thrown into space diminishing star’s power to shine. Nevertheless, scientists argue that these material ejected into space could not come from the host star. The explanations issued by astronomers support the idea that those plasma balls were sent into space by another star which seems to be a companion of the host one. If that is so, the companion may be situated in an elliptical orbit which raises it near the giant star’s hot atmosphere every eight years.
When the companion star enters V Hydrae’s atmosphere, it begins to shoot balls of incandescent plasma through space. The speed of the ejected plasma is approximately half million miles/hour. Raghvendra Sahai, who is the lead author of the study and comes from NASA’s Jet Propulsion Laboratory in California, argues that he is building a link between this star and its companion, and the glowing activity usually noticed around the dying stars over the years. These dying stars were known as “planetary nebulae” which represents a globe consisting of glowing gas.
Hubble had previously registered some images of gas clouds emission coming from planetary nebulae, which are linked to dying stars.
Isn’t this an amazing piece of information concerning the life of a star? Aren’t you curious to find more about the death of a star?
