![]() And if you like the Aerial app, you can always buy the developers a coffee. You can also pick whether you want an icon in the menu bar to notify you or not.Īerial 2 also introduced Community Videos, including 20 screen savers donated at no charge by Joshua Michaels and Hal Bergman. You can choose whether updates should happen automatically in the background, or if you prefer to be notified. The easiest way to get it on your Mac is to download the Aerial Companion from Coates' GitHub page, drag the app to your Applications folder, launch it, and then follow the quick setup process. In addition, Aerial has some additional options, including the ability to filter video themes, overlay weather data, and adapt the videos that are played to the time of day, plus it offers an additional library of over 100 different videos. So while it's not possible to choose a specific screensaver on Apple TV once it's downloaded, you can on your Mac, thanks to Aerial. The app periodically scrapes the screen savers from Apple's servers and lets you choose your favorite videos so that they play more often. There are eight new backgrounds, and you can download them below. But when you do, and if you like them, you'll be happy to learn that you can get them on your Mac, too.Ĭreated by developer John Coates and maintained by Guillaume Louel, Aerial is a free and open source app for macOS 10.12 and later (including Monterey and Apple silicon) that lets you view the same high-quality Apple TV screen savers on your Mac. NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.Traveling along the coast of the Isle of Skye, Scotland Apple TV downloads new screen savers on a regular basis depending on your Apple TV settings (daily, weekly, or monthly via Settings -> General -> Screen Saver -> Download New Video), so you may not see them immediately. The Carina Nebula is home to the Keyhole Nebula and the active, unstable supergiant star called Eta Carinae. Visible from the Southern Hemisphere, it is located at the northwest corner of the Carina Nebula (NGC 3372), which resides in the constellation Carina. Located roughly 7,600 light-years away, NGC 3324 was first catalogued by James Dunlop in 1826. This period of very early star formation is difficult to capture because, for an individual star, it lasts only about 50,000 to 100,000 years – but Webb’s extreme sensitivity and exquisite spatial resolution have chronicled this rare event. An unusual “arch” appears, looking like a bent-over cylinder.A “blow-out” erupts at the top-center of the ridge, spewing gas and dust into the interstellar medium. ![]() Protostellar jets and outflows, which appear in gold, shoot from dust-enshrouded, nascent stars.Bubbles and cavities are being blown by the intense radiation and stellar winds of newborn stars.Dramatic pillars rise above the glowing wall of gas, resisting the blistering ultraviolet radiation from the young stars.The “steam” that appears to rise from the celestial “mountains” is actually hot, ionized gas and hot dust streaming away from the nebula due to intense, ultraviolet radiation.Several prominent features in this image are described below. NIRCam – with its crisp resolution and unparalleled sensitivity – unveils hundreds of previously hidden stars, and even numerous background galaxies. ![]() The high-energy radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, this image reveals previously obscured areas of star birth.Ĭalled the Cosmic Cliffs, the region is actually the edge of a gigantic, gaseous cavity within NGC 3324, roughly 7,600 light-years away. What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula.
