beige.party is one of the many independent Mastodon servers you can use to participate in the fediverse.
A home to friendly weirdos. The Grey Gardens of the Fediverse (but beige). Occasionally graphically cacographic. Definitely probably not a cult (though you'll never be 100% sure). Beige-bless 🙏

@AstroMigration Post of the Day

Speaking of #Starlink, today's #POTD (mastodon.social/@sundogplanets) goes to astronomer Prof. Sam Lawler @sundogplanets:

"Almost all the satellites you can see with your eyes now are Starlinks. Nicely demonstrated in this awful/beautiful photo: apod.nasa.gov/apod/ap220614.ht "

Thank you Prof. Lawler for continuing to remind the world of the catastrophe unfolding in low earth orbit.

Explanation: What are all those streaks across the background? Satellite trails. First, the foreground features picturesque rock mounds known as Pinnacles. Found in the Nambung National Park in Western Australia, these human-sized spires are made by unknown processes from ancient sea shells (limestone). Perhaps more eye-catching, though, is the sky behind. Created by low-Earth orbit satellites reflecting sunlight, all of these streaks were captured in less than two hours and digitally combined onto the single featured image, with the foreground taken consecutively by the same camera and from the same location. Most of the streaks were made by the developing Starlink constellation of communication satellites, but some are not. In general, the streaks are indicative of an increasing number of satellites nearly continuously visible above the Earth after dusk and before dawn. Understanding and removing the effects of satellite trails on images from Earth's ground-based cameras and telescopes is now important not only for elegant astrophotography, but for humanity's scientific understanding of the distant universe.

@mastodonmigration @AstroMigration @sundogplanets How long was this exposure?

How come all photos don’t look like this?

@glasspusher @mastodonmigration @AstroMigration @sundogplanets Yeah, it's a composite of multiple time frames.

I spend way too much time trying to explain things to "moon and globe skeptics", and for this type of artistic work to be presented by NASA is distinctly unhelpful.

I consider myself a fan of NASA and even I feel it's somewhat deceptive.

@marshray @mastodonmigration @AstroMigration @sundogplanets the pic on apod has the description of how that image was made right below it. I don’t consider that deceptive. Satellite trails are what professional astronomers have to deal with.

Thanks for trying to educate the moon and globe skeptics, though. Those folks have bigger problems…
