For anyone else who had a hard time parsing the title:
The New Horizon probe, which is now 50 times as far from the sun as Earth, photographed Voyager 1's location.
No, you can't see Voyager 1 in the photograph.
- Aardwolf 6y agoIs that different from photographing Voyager 1's location from Earth?
- falcolas 6y agoOne of the later links in the article points out that the starfield is visibly different than what we can see from earth (due to parallax), so yes, it would be.
- DougMerritt 6y agoThe link in question is [1]. I was a little surprised at this, because 50 A.U. is less than 1/10 of 1% of a light year, so the view shouldn't have changed that much -- but sure enough, in a closeup view with a stereoviewer or blink comparator, one can see Proxima Centauri and (in a separate view) Wolf 359 change apparent positions a little. Nonetheless one shouldn't be disappointed that most stars haven't visibly shifted.

- rhn_mk1 6y agoHow does the parallax due to being in a different point within the Solar System compare to the parallax due to the Solar System itself moving relative to the Galaxy? Is this the magnitude of parallax effect we could observe within a couple years while sitting here on Earth?
- layer8 6y ago[0] mentions “a typical Sun-relative 20–200 kilometers per second”, which would translate to 1.2-12 years for a 50 AU displacement, but only for stars that move 90° perpendicular to the sun; and for stars that are further away than Proxima Centauri or Wolf 359 you have to multiply with a corresponding factor. So I think it’s typically more in the range of centuries. [0] https://en.m.wikipedia.org/wiki/List_of_nearest_stars_and_brown_dwarfs https://en.m.wikipedia.org/wiki/List_of_nearest_stars_and_br...
- _verandaguy 6y ago>No, you can't see Voyager 1 in the photograph. I'm still holding out hope for next-gen long-range robotic space probe selfie tech.

- yummybear 6y agoI wonder how many billionths of a pixel voyager takes up, if that’s even enough
- slg 6y agoFrom the photo's caption: >Voyager 1 itself is about 1 trillion times too faint to be visible in this image Although that is such a nice round number that I wonder how much work the "about" is doing in that sentence.
- tinus_hn 6y agoIf I point my camera to the sky and photograph it I have a roughly 50% chance of photographing Voyager 1’s location, in that sense.
