- m4x 5y agoThat is a strikingly beautiful photo. Thanks for sharing it
- jiggawatts 5y agoBut it’s in Flickr, so all interaction is blocked including zoom. I see about 600x400 pixels of that photo. What a wonderful Internet we’ve made for ourselves.
- leijurv 5y agoThere's a download button in the bottom right, if you hit Original you get the actual original. Here it is: https://live.staticflickr.com/65535/51847931721_c3feebd201_o_d.jpg https://live.staticflickr.com/65535/51847931721_c3feebd201_o...
- _ph_ 5y agoI am just wondering what is it that prevents that link to open the image in a browser window but forces a download of it?
- danielbln 5y agoUsually it's a HTTP header that's sent to your browser: Content-Disposition: attachment
- _ph_ 5y agoThanks, I had always wondered why some sites behave differently with some file types. A bit annoying, if you just want to glance at something for a while but not keep it around for longer.
- danielbln 5y agoThere are browser addons that force the browser to ignore this header, for chrome e.g. https://chrome.google.com/webstore/search/undisposition?hl=en https://chrome.google.com/webstore/search/undisposition?hl=e....
- est31 5y agoOr content-disposition as of HTTP/2. Just verified with the browser console that it's sending that header (and using HTTP/2).
- _a9 5y agoSpecific to Flickr URLs, its the '_d' at the end. Remove it and you can view it normally in the browser. But as danielbln wrote, that 'Content-Disposition' header is what forces a download in general. https://live.staticflickr.com/65535/51847931721_c3feebd201_o.jpg https://live.staticflickr.com/65535/51847931721_c3feebd201_o...
- Cthulhu_ 5y agoProbably a courtesy from the website owner to not cause a runaway browser tab as it tries to render 60MB of image. I mean the first internet-connected computers like the imac g3 had only 32 MB of memory.
- jcims 5y agoSomehow I rage slapped my way out of that. No idea what I did. I just don't understand the underlying motivation to lock things down like that. It like a cortisol fountain and I get wholly irrationally unreasonably mad. It's actually funny in retrospect.
- the_biot 5y agoRemember that time Yahoo made Flickr ridiculously slow to access from Europe, to the point where it wasn't actually usable? Lasted near 10 years I believe. Hah, good times.
- holoduke 5y agoOverride zoom settings in your browser. A must have on mobile. Use it all the time.
- raattgift 5y agoJudy Schmidt has combined this with Spitzer/WISE infrared data to produce the following image, and has added annotations for some of the more prominent structures (mostly the radio arc and supernova remnants in the galactic centre direction) : https://www.flickr.com/photos/geckzilla/51854563587/ https://www.flickr.com/photos/geckzilla/51854563587/ and the deep link (9144 x 5964, but no annotations) for people who have trouble with flickr's UI: https://live.staticflickr.com/65535/51854563587_4446b5cd40_o_d.png https://live.staticflickr.com/65535/51854563587_4446b5cd40_o...
- JohnJamesRambo 5y agoI think I need to print that out, that’s wild. I’ll have to get on my desktop because that site is hilariously useless on my mobile.
- heavyset_go 5y agoSecond link is gone.
- kumarvvr 5y agoNever thought about Flickr till now, been almost a decade.
- jl6 5y agoThis is an incredible image and the filaments are super-mysterious. Do you know how large the objects in the image are? Are we looking at the whole Milky Way or a very zoomed-in part of the center?
- stargazer-3 5y agoZoomed-in part in the center, "1400 light-years across the centre of the Galaxy." as a linked paper indicates. Milky Way is long, 105700 light years in diameter.
- raattgift 5y agoAlong these lines, why SARAO's MeerKAT radio telescope (https://www.sarao.ac.za/science/meerkat/about-meerkat/ https://www.sarao.ac.za/science/meerkat/about-meerkat/) is the observatory behind this discovery is that it has a good view of the galactic centre because of the orientation of the Earth and solar system within the galaxy : https://commons.wikimedia.org/wiki/File:Motion_of_Sun,_Earth_and_Moon_around_the_Milky_Way.jpg https://commons.wikimedia.org/wiki/File:Motion_of_Sun,_Earth...
- msaharia 5y agoThis is perfect for a Desktop Wallpaper. Thanks for sharing!
- mensetmanusman 5y agoTo download this on the iPhone: – request desktop view – in the bottom right push the down arrow and select original - a PNG file will download that you can open and save
- neolefty 5y agoThank you! There are high-res versions of the images from the article embedded in the PDF (linked in the article) as well. (You can use pdfimages to extract them.)
- parf02 5y agowhat is the orange beam in the pictures with the telescope?
- blincoln 5y agoMost likely a laser guide star[1]. [1] https://en.wikipedia.org/wiki/Laser_guide_star https://en.wikipedia.org/wiki/Laser_guide_star
