"name": " The image shows a detailed view of Supernova 1987A, a bright supernova observed in the Large Magellanic Cloud in 1987. The central object is the remnant of the supernova explosion, surrounded by curious outer rings that appear as a flattened figure 8. The image is credited to ESA/Hubble and NASA. The text below the image explains the mystery of the rings' origin, suggesting that they could be caused by beamed jets from a hidden neutron star or the interaction of the progenitor star's wind with gas released before the explosion. The image was taken in 2011 by the Hubble Space Telescope. The text also mentions that the origin of the rings remains a mystery despite monitoring by large telescopes. The image is part of the Astronomy Picture of the Day (APOD) series, with the next day's picture being \"aurora caldera.\"\n\n Ovis2-8B\n\n🌱 Energy used: 0.240 Wh",
