What does Venus ACTUALLY look like?
In which I attempt to explain why images of Venus look so different from the real thing.
Correction:
- The image of Neptune I showed at 10:32 has higher contrast than the planet would have to the human eye due to a lack of gamma correction according to Irwin et al., 2023:

Other Addendum:
- Something I should've mentioned in the description of SAR at 1:15 is that the time to return is used to determine both the altitudes of points on the surface and to determine how far from the satellite's track the point seen is, which can have a foreshortening effect and create "shadows" behind tall structures where the radar couldn't reach. Th...

The Liberian County Flags Animated
Просмотров 66 тыс.3 года назад
County names are in captions. I love the Liberian county flags because they manage to be a genuinely unique and memorable set of flags for relatively small regions without falling into many of the pitfalls that tend to plague flags made for smaller regions of other countries. Contrast these with the flags of lesser known cities and regions in other countries and you'll see that the vast majorit...
The Mass of the Solar System Visualized

I got the total masses for the asteroid belt and Kuiper belt scattered disc from: Masses of the Main Asteroid Belt and the Kuiper Belt from the Motions of Planets and Spacecraft (link.springer.com/article/10.1134/S1063773718090050) I believe this paper treats the scattered disc as part of the Kuiper belt, though it's often treated as a separate thing.

The Animated State Flags of America [Updated for Mississippi!]

Names can be turned on in captions. An animation I created back in April-since then Mississippi has created and approved a new flag, so I redid the animation to include it. I've included the flags of every state, as well as the territories and DC. Music: The US Army Band's performance of The Star Spangled Banner

    Good job man. I love using these as screensavers! Personally, I'd save Guam, DC and other territories for the end. From a history teacher's perspective, some get confused on what are states and what aren't. And maybe just a little slower time-wise for the states that spun around between 0:19 - 0:49

    So Venus is almost like Titan, atmosphere too dense to know what its really like. Remember, the human eye can discern a lil bit more than just the visible color spectrum, so if a human manned spacecraft was close to its orbit, they will be able to see more than jusy boring yellow

    Earth starts spinning slower than... - Haumea (3 h 56 min 44 s): always has - Ceres (9 h 4 min 27 s): 4333 MYA - Jupiter (9 h 55 min 33 s): 4216 MYA - Saturn (10 h 32 min 36 s): 4113 MYA - Neptune (16 h 6 min 36 s): 2909 MYA - Uranus (17 h 14 min 24 s): 2649 MYA - Makemake (22 h 49 min 36 s): 219 MYA (Current rotation of the Earth - 23 h 56 min 4 s) - Mars (24 h 37 min 23 s): Future - Pluto (6 d 9 h 17 min 32 s): Future - Eris (15 d 18 h 51 min 42 s): Future - Mercury (58 d 15 h 30 min 30 s) and Venus (243 d 0 h 33 min): Never - will tidal lock to the Moon before reaching it. Caveat: this assumes that the other planets have never and will never change their rotation periods, which is very likely false!

    These are good concepts but so poorly executed that it’s a national embarrassment. All we had to do was create a seal and properly embroider it on a flag (like every other state, county, region, country, etc.) … but M S P A I N T. 🤦😬

      I saw that article and I'm actually (edit in case anyone sees this later: I misremembered what was said, the article claims the contrast was boosted and that's correct so skeptical was the wrong word to use here) skeptical of the claims in it, I can't remember the full details of it at the moment but if I remember right the colors in the image they showed were basically the same as usually assumed when I adjusted the luminosity and contrast, so it was a matter of gain and gamma correction; the hue and saturation weren't too different from the voyager images.

      @aaryanbhatia4939 4 месяца назад

      ​@@geobicaI'd hope you are right about Neptune's colour. I'm not super familiar on colouration terms you've mentioned, so I can't really comment on that. But it seems that "True colour" photos have replaced their original counterparts for the Wikipedia articles of Venus, Uranus, and Neptune

    • @geobica
      @geobica 4 месяца назад

      @@aaryanbhatia4939 I just looked back over the article and they do actually have a point, the difference is just brightness and contrast, but the change done to the old voyager image of Neptune is pretty significant, it's a bit like looking at the planet through sunglasses, though even that wouldn't change the contrast so much. It's a different sort of manipulation to what I was talking about with Venus, but yeah if you were there in person, based on what they say in the article it would definitely look a lot paler than the old image. I'll add a correction in the description.
