This is about 160,000 light years away in the direction of DoradoSupernova Remnants “DEM L 190”in. DEM L 190 is located in the “Large Magellanic Cloud” (Large Magellanic Galaxy), one of the companion galaxies (satellite galaxies) of the Milky Way. You can see that it has a complex structure with complex filaments and thin layers of gas.
A supernova remnant is a celestial body observed after a supernova explosion by a massive star eight times more massive than the Sun. The shock waves produced by the supernova explosion spread into the surroundings, heating the gas and emitting electromagnetic waves such as visible light and X-rays. DEM L 190 is the brightest supernova remnant in the Large Magellanic Cloud, according to the European Space Agency (ESA).
This image is“Hubble” Space Telescope.It was created based on images obtained using the “Wide Area Planetary Camera 2 (WFPC2)” which was on board between 1993 and 2009. DEM L 190 observation data from the Hubble Space Telescope shows the interaction between the supernova remnant and the interstellar medium, and the soft gamma-ray repeater hidden in DEM L 190.※It is said to have been used for research to identify The image from DEM L 190 acquired by WFPC2 was released 19 years ago in July 2003, but this time the image used additional data and improved image processing technology.
*…a neutron star (magnetar) that emits irregularly repeating bursts of gamma rays and X-rays
The image was first released by ESA on November 28, 2022 as one of the Hubble Space Telescope images of the week.
