Enceladus: How to Keep a Young Moon Looking Old

...present analysis. No Model Is Assumption-Free Nevertheless, the authors boast that “The CPF is derived directly from crater counts instead of model-based predictions.” Sticking to the crater observations alone, though,...

Keeping Titan Old Despite Evidence of Youth

...could be up to a billion years old using “crater scaling laws” (a statistical model; see problems with crater count dating, 22 May 2012, 29 Jan 2019). That’s a problem...

Mars Youth Shows in New Study

...recognizable form. Here we address one of these processes—impact cratering—in detail. We use standard crater counting age models to generate synthetic, global populations of craters and intersect them with hypothetical...

Young Saturn Refuses Billions

Planetary scientists are trying hard to get Saturn and its moons to take billions of years, to no avail.   For review, consider what the moyboys are up against. Observational...

Our Moon Refuses to Obey Scientists

...Nov 2020 issue). Some scientists still haven’t given up on crater count dating, in spite of its numerous unverifiable assumptions and problems (19 Jan 2019, 30 Oct 2018). This duo...

What the Apollo Rock Samples Revealed About the Moon

The lunar rocks changed what scientists thought they knew about our satellite, but raised many more questions. Here’s how Richard W. Carlson begins his article in Science Magazine: “The analysis...

Counting Craters: Bad Assumptions Undermine Reliability

...that their variables depend on. If neither are reliable, the conclusions cannot be more reliable. Crater Count Uncertainties: Problems with crater count dating were almost completely ignored in this paper...

Crater Count Dating: Self-Secondaries Reduce Age Estimates

...scientists have long used crater counts to estimate the age of a surface. In short, the more craters, the older the surface. That seemed reasonable until secondary cratering smudged the...

Time to Revisit the Lunar Dust Problem?

...times about the “impact” of secondary craters on crater count dating (e.g., 22 May 2012, 19 Oct 2015, 12 Oct 2016). One impact on Mars could launch a million secondaries,...

Moon Just Got 100-fold Younger

...Than Thought.” Part of the new estimate comes from crater counts by LRO, including a whopping 222 new craters appearing just in the last 7 years, says Alexandra Witze in...

Pluto Has Active Geology

Convection apparently forms the polygonal cells in Sputnik Planum, a large active region on Pluto’s surface. Feel the burn in this exclamation from the New Horizons team posted by NASA...

Titan Takes the Age Stage

Saturn’s giant moon has prompted a flurry of new science papers. Can anyone keep it billions of years old? Ever since the predicted global ocean on Titan was falsified, planetary...

First Pluto Papers Published

...far is amazing. The Pluto system is “yold” (see Darwin Dictionary), but there are reasons to favor the young side. The scientists like to say, based on crater counts, that...

Surprising Youth in the Solar System

Four solar system objects in the news look young, not billions of years old. Pluto: It’s officially published in peer-reviewed literature: the surface of Sputnik Planum on Pluto cannot be...

Pounding Headaches for Solar System Dates

...Well, which is it? Those are very different scenarios. “Crater counting from high definition images is very important and could serve for the determination of the age of the surfaces.”...
