![]() ![]() # with metadatas in YAML format (HTML is stripped) # Downloads NASA Astromy Picture of the Day apparently symlink will fail when asked to overwrite a link. If you're going to use this in Windows, you should at the very least set $LINK to undefĮDIT: added a line to remove old CURRENT link before updating it. If you want to use this, you should probably tinker with it to suit your needs. I had to use some pretty ghetto techniques to parse the APOD page, which is completely invalid and uses no semantic markup at all, so I figured I might as well ghetto-ize the whole script. I used a number of such "ghetto" Ways To Do It (noted in comments) because I wanted to keep it simple and functional. Also the script will refuse to overwrite files, because that makes sense to me. The date is not validated beyond checking that it consists of 6 digits. You can also pass a date as the argument (in YYMMDD format, to match the URL format of the APOD archive) to fetch old pictures. Depending on your WM, it may be simpler to create overlays/widgets/gadgets/etc. This would require the display resolution to be provided in the config section so as to render the text in an appropriate size and position relative to the screen. ![]() The metadata (title, credit, description) is extracted from the page and stored in a YAML file, mainly because I'm considering adding an ImageMagick script to create an annotated image. The default functionality will maintain a symlink to the latest image providing easy access for a WM or whatever else you want to use it. These captivating visuals range from mesmerizing images of distant galaxies and nebulae to close-up views of planets, moons, and other celestial objects.The intended use is to run it as a cron job. Studying the supernova in such close proximity may unlock valuable insights into the life cycles of massive stars and the processes that govern their explosive fates.įor the unversed, NASA's APOD features a different astronomical image each day, captured by ground-based and space-based telescopes, along with a detailed description provided by a professional astronomer. Initial findings indicate that SN 2023ixf belongs to the Type II supernova category - a cataclysmic occurrence that transpires when a massive star exhausts its nuclear fuel and succumbs to gravitational collapse.Īstronomers predict that SN 2023ixf will continue to brighten and remain visible to telescopes for several months, providing an extended window of opportunity for in-depth exploration. The proximity of this cosmic spectacle presents a remarkable opportunity for researchers to delve into the intricacies of a supernova's birth. It ranks as the second closest supernova observed within the past decade and marks the second supernova detected within M101 in the past 15 years. SN 2023ixf was detected merely three days ago and was subsequently located on automated images from the Zwicky Transient Facility two days earlier. They are among the most energetic events in the universe, releasing an enormous amount of energy and producing intense brightness that can outshine entire galaxies. In case you have been living under a rock, supernovas are incredibly powerful and dramatic stellar explosions that take place at the end of a massive star's life cycle. In a momentous astronomical event, esteemed Japanese astronomer Koichi Itagaki recently discovered a supernova, dubbed SN 2023ixf, in M101, which lies only about 21 million light-years away, making it the closest supernova seen in the past five years. NASA's Astronomy Picture Of the Day (APOD) features the Pinwheel Galaxy or M101, one of the most well-known and visually striking galaxies in the night sky.
