This is about 160,000 light-years away in the direction of DoradoSupernova Remnant “DEM L 190”is. 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 complicated structure with intricate 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 generated by the supernova explosion spread to the surroundings, heating the gas and emitting electromagnetic waves such as visible light and X-rays. According to the European Space Agency (ESA), DEM L 190 is the brightest supernova remnant in the Large Magellanic Cloud.

This image is“Hubble” Space TelescopeIt was created based on images acquired using the “Wide Area Planetary Camera 2 (WFPC2)” that was on board from 1993 to 2009.Observation data of DEM L 190 by the Hubble Space Telescope show the interaction between the supernova remnant and the interstellar medium, and the soft gamma ray repeater hidden in DEM L 190.(※)It is said that it was used for research to identify The image of 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.

The first image was released by ESA on November 28, 2022 as one of the Hubble Space Telescope’s images of the week.
