Hubble picture of celestial fireworks
A newly launched picture from the Hubble Space Telescope reveals shreds of the colourful supernova remnant DEM L 190. The fragile sheets and complex filaments are particles from the cataclysmic demise of an enormous star that when lived within the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. As a matter of reality, DEM L 190 – also referred to as LMC N49 – is the brightest supernova remnant within the Giant Magellanic Cloud. It shines with an obvious magnitude of +12.7, regardless of being roughly 160,000 light-years away from Earth within the constellation Dorado.
Information from 2 devices
To make clear, this new picture combines information from two completely different Hubble devices. The primary one is the retired Extensive Area and Planetary Digital camera 2 (WFPC2). The second instrument is its substitute, the extra highly effective Wide Field Camera 3. However, throughout its operational lifetime, WFPC2 produced many memorable pictures.
First, astronomers used the 2 WFPC2 investigations of DEM L 190 as a pure laboratory to review the interplay between supernova remnants and the interstellar medium, the tenuous combination of gasoline and dust that lies between stars. Then, within the second research, astronomers turned to Hubble to pinpoint the origin of a gentle gamma-ray repeater, an enigmatic object lurking in DEM L 190 that repeatedly emits high-energy bursts of gamma rays.
By the best way, Hubble additionally imaged DEM L 190 in 2003. So this newly launched picture incorporates extra information with improved image-processing methods, bringing out extra element of the supernova remnant.
