A fictional Grand Tour portrays Pluto as it really is
NASA's New Horizons mission to Pluto has forced astronomers to rewrite their textbooks — but that's not all: New Horizons also forced Les Johnson to rewrite a novel.The space scientist was tasked with taking notes that the famed science-f

A cousin for Pluto? New dwarf planet candidate found
Astrophysicists say they've identified an object beyond the orbit of Neptune that's likely to qualify as a dwarf planet, alongside other trans-Neptunian objects including Pluto, the erstwhile "ninth planet."The discovery of 2017 OF201 touches upon another ninth-planet contr

How did #Pluto get its heart? Scientists say it involved a cosmic "splat." (Yes, that's the scientific term.) The newly published study is a nice follow-up to my book about the little guy, "The Case for Pluto." https://cosmiclog.com/2024/04/15/how-did-pluto-get-its-heart-scientists-suggest-an-answer/ #Space #DwarfPlanets

How did Pluto get its heart? Scientists suggest an answer
The most recognizable feature on Pluto is its “heart,” a relatively bright valentine-shaped area known as Tombaugh Regio. How that heart got started is one of the dwarf planet’s deepest mysteries — but now researchers say they’ve come up with the most likely scena

#Eris and #Makemake may be dwarf planets, but they're not dead planets: Scientists analyzed data from NASA's James Webb Space Telescope and found evidence pointing to geothermal activity deep within those mini-worlds. https://cosmiclog.com/2024/02/16/webb-telescope-detects-activity-within-dwarf-planets/ #Space #JWST #DwarfPlanets #Planets

Webb Telescope detects activity within dwarf planets
They may be dwarf planets, but they're not dead planets.NASA's James Webb Space Telescope has provided scientists with evidence of geothermal activity deep within two far-out dwarf planets, Eris and Makemake.

Eris may be larger than Pluto (we can't be sure as it's apparently very difficult to get an accurate measure of how big such distant planets actually are) and it was initially described as the tenth planet. It was the discovery of Eris that first sparked the debate over the definition of a planet, which led to Pluto being demoted to "dwarf planet" along with Eris.
10 things you might not know about Eris:

4 out of 5 #Uranus #moons likely to have #ocean under crust
A preview of what #UranusOrbiter and Probe might find in the 2040s
The #water is believed to be located between the core and icy crusts in oceans 30km deep for moons Ariel and #Umbriel, and less than 50m for #Titania and #Oberon.
It's not uncommon to find water in dwarf #planets and moons. For example, #dwarfplanets #Ceres and #Pluto, as well as #Saturn's moon #Mimas, have all shown evidence of liquid water.

Pluto team updates science from the solar system’s edge
Nearly eight years after its historic Pluto flyby, NASA’s New Horizons probe is getting ready for another round of observations made from the icy edge of the solar system — and this time, its field of view will range from Uranus and Neptune to the cosmic

'Impossible' new ring system discovered at the edge of the solar system, and scientists are baffled. A ring looping around the icy dwarf planet Quaoar is located much farther from its parent body than was thought was possible.

Phil Plait gives us a look at how the other side of Pluto looks like.
"In a recently published paper, the planetary scientists on the New Horizons team described these images and what they may be saying about the semi-frozen rock-and-ice world at the edge of the solar system."
