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. On Twitter, Facebook, Google News, and Instagram.The intended use is to run it as a cron job. Other satellite galaxies of M63 can be spotted in the remarkable wide-field image, including faint dwarf galaxies, which could contribute to M63's star streams in the next few billion years.įollow HT Tech for the latest tech news and reviews, also keep up with us Extending nearly 180,000 light-years from the galactic center, the star streams are likely remnants of tidally disrupted satellites of M63. This exceptionally deep exposure also follows faint, arcing star streams far into the galaxy's halo. Its bright core and majestic spiral arms lend the galaxy its popular name, The Sunflower Galaxy. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across, about the size of our own Milky Way. Their whirled arms are typically full of gas and dust, which helps give rise to the bright, younger stars visible throughout their length.Ī bright spiral galaxy of the northern sky, Messier 63 is nearby, about 30 million light-years distant toward the loyal constellation Canes Venatici. Spiral Galaxies like M63 are disks of stars, gas, and dust that have bright bulges in their centers made up primarily of older and dimmer stars. Also known as NGC 5055, this spiral galaxy spans almost 100,000 light-years. Today's NASA Astronomy Picture of the Day is a snapshot of the M63 Curly Spiral Galaxy located about 30 million light-years away towards the constellation Canes Venatici. These types of galaxies have winding spiral arms that make them look a little like massive pinwheels. One of the most visually appealing celestial objects captured by NASA is spiral galaxies. But how does NASA capture these objects that are located millions of kilometers away in space? The space agency uses its advanced telescopes such as Spitzer Space Telescope, the Hubble Space Telescope, and the newly launched James Webb Space Telescope. Over the past few days, we have seen NASA publish mesmerizing snapshots of celestial objects as part of its daily Astronomy Picture of the Day.
