Anyone know why the text on the comic was heavily aliased (pixelated edges), although it's since been fixed on the xkcd website? [[User:Keavon|Keavon]] ([[User talk:Keavon|talk]]) 07:45, 1 June 2015 (UTC)

:Probably a bad setting on the PNG compression by Randall when saving.  Maybe he's trying to optimize file size (although in this case, the quality suffered). --BigMal // [[Special:Contributions/108.162.238.192|108.162.238.192]] 11:53, 1 June 2015 (UTC)

:Did the quality of the comic improve over time? Might have been a reference to the images provided by new horizons becoming more clear as it approached[[Special:Contributions/108.162.215.113|108.162.215.113]] 12:51, 5 June 2015 (UTC)
 
:There's some weirdness in the earth images, too. You can see it if you bump the contrast and brightness a bunch -- there's a rectangular box around Earth, which it sits at the right end of. There's also a slight gradient in the box that's brighter at the right side, a couple of meandering green lines in the brightest part of the gradient, a series of green X shapes at lower left, and a repeating pattern of green, blue and pure black at top left. Curious, could be intentional or simply an artifact of how Randall made the image. [[Special:Contributions/108.162.217.167|108.162.217.167]] 21:21, 22 June 2015 (UTC)
 
  
 
According to Wikipedia, "in August 2014, astronomers made high-precision measurements of Pluto's location and orbit around the Sun using the Atacama Large Millimeter/submillimeter Array to help NASA's New Horizons spacecraft accurately home in on Pluto." Was Steve involved in these measurements too? (And any of the numerous ways by which it can be determined how far away NH is and which way it is travelling!)--[[User:Laverock|Laverock]] ([[User talk:Laverock|talk]]) 12:43, 1 June 2015 (UTC)

:I think that -is- Earth, a view of the probe right after it was launched.  Then again... Classic Star Trek episode "Miri" is set on a distant planet with identical continents to Earth for no reason except to get you interested quickly.  It was made before "Planet of the Apes" by the way (spoiler).  An unsatisfactory novel called "Preserver" revisits it and proposes there are super-powered aliens just messing with us.  Actually in Star Trek there are super-powered aliens just messing with us about every third week and they usually constructed their own gonzo planet just for that purpose, so the assumption that these are new, unknown super-powered aliens is unjustified, but of course true (The Preservers), unless they are really Organians or Q but they just don't say so.  And if the Planet Copiers are abroad, who's to say that Earth is the original.  Outside Trek, it's also even odds that a fictional Counter-Earth planet on the other side of the sun - there have been several although it's physically impossible - has identical continents to Earth.  And in "D.R. and Quinch Have Fun On Earth", our continents are alien graffiti, unfortunately leading to cleanup.  Love, Robert Carnegie  [email protected] [[Special:Contributions/141.101.99.123|141.101.99.123]] 11:17, 12 June 2015 (UTC)
 
  
 
I do not know if the image is concept art for the New Horizon mission from back in 2006; or if it is a more generic space exploration art work.  It is hard to imagine that it is specific to the New Horizon’s Mission.

It uses the gravity of a planet to alter the path and speed of a spacecraft. [http://en.wikipedia.org/wiki/Gravity_assist Reference] I guess Steve miscalculated the maneuver. --[[User:Arturotena|Arturotena]] ([[User talk:Arturotena|talk]]) 06:41, 1 June 2015 (UTC)

I believe this really requires three bodies to work. The close passage by the small object slightly alters the orbital elements of the larger body (around the largest body, in this case, the sun), while also changing the orbit of the small body, both direction and speed.--DrMath 06:44, 27 May 2018 (UTC)

;No rotation and an imminent impact?
 
 
Most likely it's just a concession to making the cartoon easier to draw, but I'd note that between the third and fifth frames, Earth appears not to rotate noticeably. That implies either extreme speed, or less likely, slow enough speed that Earth is conveniently managing one or more complete rotations between frames. Since the conversation is implied to continue throughout, we can safely presume the former. That suggests an imminent collision somewhere on (or near) the southern coast of Yemen.

I didn't even see this as a representation of Earth. As I looked at each image, I thought I was seeing an image of Goofy (rather than Pluto) as seen through a glass orb. [[Special:Contributions/108.162.237.165|108.162.237.165]] 20:26, 9 June 2015 (UTC)
 
 
I've fixed the three opaque links.  I'll remove the incomplete tag in the next few days, unless anybody objects. [[User:Cosmogoblin|Cosmogoblin]] ([[User talk:Cosmogoblin|talk]]) 14:10, 24 June 2015 (UTC)
 
 
108.162.215.26 (why are all the anonymous contributors on this page Californian? You're the other side of the country, you don't need to worry about NASA missions exploding!) added a link about the worst-case scenario in the event of a launch disaster, but just copied it from Wikipedia without checking - it was broken, so I searched for the source and fixed it.  In doing so, I had a look at what the report says, and I'm not convinced the text from Wikipedia (sourced originally from "The Cosmic Compendium", ISBN 978-1329022027) is correct.  The report indicates on page 4-30 that the scenario mentioned would result in "0.4 mean health effects", whereas a less likely scenario mentioned directly below that would result in "102 mean health effects", about 250 times worse.  Still, it's from a cited, published source, and if anybody's wrong, it's Rupert W Anderson.

Cosmogoblin, the entirety of the text from "The Cosmic Compendium" by Rupert W Anderson is taken word for word straight from Wikipedia. So you didn't really chase your source far enough, I don't think. "Rupert" goes so far as to actually cite every single one of his sources as Wikipedia along with relevant licenses (public domain or creative commons) so I'm guessing that book is scamming people who don't realize what they're buying. {{unsigned ip|173.245.55.66}}
 
 
From one IP to another: [https://www.explainxkcd.com/wiki/index.php?title=1532:_New_Horizons&curid=16349&diff=221594&oldid=200453 this was probably ''not'' a typo] - 'pane', as in '{{w|Windowpane|window pane}}', was valid. As 'panel' is, so no skin off my nose, and I (probably?) didn't write the original. But it's not a necessary edit so I'm hoping no-one goes off to do a mass-replacemenf. (And this comment is the best/only way to possibly get the attention of the unnamed editor concerned, or anyone else lurking on Recent Changes or otherwise randomly landing here.)
