I love this decorative Art Nouveau metal plaque of Neptune in a doorway of the Miller and Lang building on Darnley Street in the Pollokshields area of Glasgow.
#PPOD: This is how NASA's Voyager 2 spacecraft saw Neptune, the other blue planet, in true color on 17 August 1989, based on a re-analysis of the original data by Patrick G J Irwin et al 2024. Credit: NASA/Voyager 2/PDS/OPUS/Ardenau4
We continue with Jonathan Fortney on GJ436 b - the original archetype #warm#Neptune
It has an intriguingly “large” eccentricity (I disagree that 0.14 is large sorry 🤓).
Thermal emission from the planet showed to be different for the #Spitzer points, at the time explained through atmospheric chemistry: non-equilibrium + mixing.
Reanalysis + follow-up showed a lower point at 3.6 micron, so less bright, but still brighter. Suggestion: tidal heating driving up the interior? #ExSSV
Gibt es hier eine Person, die rein zufällig einen #Neptune 4 (Pro) 3D Drucker von #Elegoo hat, hier in Deutschland wohnt und ein 10 neue Nozzles (Dritthersteller) zum Selbstkostenpreis von 10€ inkl. Versand benötigt?
Ich habe mich leider verklickt und diese Nozzles passen nicht an meinen Drucker.
If it were ever possible to take a flight through the extreme conditions of Neptune's atmosphere, we might witness diamond rain tapping at our window. Science Alert has more on the research that shows how the fascinating phenomenon may be happening on more planets than we realized. https://flip.it/edHGAd #Science#Space#Diamonds#Neptune
This is very interesting... Our solar system's planet, #Neptune does not have the deep blue colour it is depicted with, as I can recall from seeing it in textbooks. It very much resembles #Uranus , in actuality. I guess the artificial colour enhancements helped to differentiate the two. And, you know, it's good that the true colour of Neptune is more like the shade of #PrinceNeptune 's first book, which is a pale teal. Seems much more fitting and appropriate, now. https://www.youtube.com/watch?v=DEs4NWfp4Ac
"For decades, images taken of Neptune have looked like the planet has a deep blue hue, while Uranus seemed more green. However, these two ice giants may actually look more similar to each other than astronomers previously believed."
Depuis presque 40 ans Neptune est représentée avec un bleu profond. En réalité ca s'approche beaucoup plus d'un bleu clair semblable à celui d'Uranus. Cette erreur est dû aux photos de la sonde Voyager 2 et du post traitement qui à été "mal" fait. Aujourd'hui cette découverte à été faite par Patrick Irwin et son équipe de l’Université d’Oxford. Ils ont traité l'image autrement
Color processing in space imagery can be tricky. For example, the colours of Uranus and Neptune; You all know the famous Voyager 2 images of both and the stark contrast of shades of blue. Well, it turns out that they have the same shades of blue. As usual, it has sparked an amusing debate online.
I must admit, this news about #Uranus and #Neptune has me shook:
"A fresh analysis of Voyager 2's images show both ice giants are in fact a similar shade of greenish blue, which is the 'most accurate representation yet' of the planets' colors, the new study finds."
Why is Neptune's moon Triton so weird? (www.space.com)
Triton orbits to the beat of its own drum.
