Moon Angell, who is rumored to be dating Dog the Bounty Hunter star Duane “Dog” Chapman , claims to be a “personal assistant” to the reality television star. Angell became linked to Chapman only because his daughter, Lyssa Chapman , called her out on Twitter for trying to move in “on a man weeks after losing his wife. God will get you MARY!!! Angell responded with another now-deleted tweet, prompting Chapman to accuse Angell of riding her father’s coattails. Riding is coat tail. B— please. Keep talking s— about his baby and see how far that gets you. Angell responded with more tweets written in all capital letters to defend herself, insisting she has been working with the Chapmans for 21 years.

Through a combination of data analysis and numerical modeling work, researchers have found a record of the ancient Moon-forming giant impact observable in stony meteorites. Their work will appear in the April issue of the Journal Science. The inner Solar System’s biggest known collision was the Moon-forming giant impact between a large protoplanet and the proto-Earth. The timing of this giant impact, however, is uncertain, with the ages of the most ancient lunar samples returned by the Apollo astronauts still being debated.

Numerical simulations of the giant impact indicate this event not only created a disk of debris near Earth that formed the Moon, but it also ejected huge amounts of debris completely out of the Earth-Moon system. The fate of this material, comprising as much as several percent of an Earth mass, has not been closely examined until recently. However, it is likely some of it blasted main belt asteroids, with a record plausibly left behind in their near-surface rocks.

Collisions on these asteroids in more recent times delivered these shocked remnants to Earth, which scientists have now used to date the age of the Moon. The research indicates numerous kilometer-sized fragments from the giant impact struck main belt asteroids at much higher velocities than typical main belt collisions, heating the surface and leaving behind a permanent record of the impact event.

Evidence that the giant impact produced a large number of kilometer-sized fragments can be inferred from laboratory and numerical impact experiments, the ancient lunar impact record itself, and the numbers and sizes of fragments produced by major main belt asteroid collisions.

Share on Twitter. By Janet Fang 04 Apr , The moon was born when a Mars-sized body impacted Earth during its very early days. The debris from both objects spewed into space and ultimately coalesced into our moon. Scientists trying to date this moon-forming impact have come up with a wide range of ages: from as early as 30 million years after the birth of the solar system to as late as million years after the Milky Way was formed.

That makes the moon millions and millions of years younger than some previous estimates, which were based on radioactive dating of elements like uranium. When you have an element with a known rate of radioactive decay, you can back-calculate a time for when collected moon rocks were formed. But geochemists disagree about these numbers a lot. By analyzing the growth history of those planets from simulations, they discovered a relationship between the time the Earth was impacted and the amount of material added to our planet after that collision.

You see, after the big moon-forming impact, proto-Earth was smashed into by other, smaller objects — these caused the Earth to gain some mass later on.

Over the last couple of days I have fallen down a research rabbit hole — I began with a question about clay minerals on Mars and find myself, today, writing about the history of major impact basins on the Moon. The trail that led me here has to do with geologic time scales — the stories that geologists tell about the major events that happened in the history of a planet. I will climb back out of the rabbit hole eventually with lots of good stories about the geology of many different planets, but I’m going to have to tell those stories bit by bit.

It all begins, appropriately, with the history of impact basins on the Moon.

The ages of Earth and Moon rocks and of meteorites are measured by as radiometric dating, are used to measure the last time that the rock.

How do scientists find the age of planets date samples or planetary time relative age and absolute age? If carbon is so short-lived in comparison to potassium or uranium, why is it that in terms of the media, we mostly about carbon and rarely the others? Are carbon isotopes used for age measurement of meteorite samples? We hear a lot of time estimates, X hundred millions, X million years, etc. In nature, all elements have atoms with varying numbers of neutrons in their nucleus.

These differing atoms are called isotopes and they are represented by the sum of protons and neutrons in the nucleus. Let’s look at a simple case, carbon. Carbon has 6 protons in its nucleus, but the number of neutrons its nucleus can host range from 6 to 8. We thus have three different isotopes of carbon: Carbon with 6 protons and 6 neutrons in the nucleus, Carbon with 6 protons and 7 neutrons in the nucleus, Carbon with 6 protons and 8 neutrons in the nucleus. Both carbon and carbon are stable, but carbon is unstable, which means that there are too many neutrons in the nucleus.

Carbon is also known as radiocarbon. As a result, carbon decays by changing one proton into a neutron and becoming a different element, nitrogen with 7 protons and 7 neutrons in the nucleus. The isotope originating from the decay nitrogen in the case of radiocarbon is called the daughter, while the original radioactive isotope like carbon is called the parent. The amount of time it takes for an unstable isotope to decay is determined statistically by looking at how long it takes for a large number of the same radioactive isotopes to decay to half its original amount.

Previous image Next image. A conventional compass would be of little use on the moon, which today lacks a global magnetic field. At some point, this dynamo, and the magnetic field it generated, petered out. The new timing rules out some theories for what drove the lunar dynamo in its later stages and favors one particular mechanism: core crystallization.

Their thinking at the time was that perhaps two mechanisms for the lunar dynamo were at play: The first could have generated a much stronger, earlier magnetic field around 4 billion years ago, before being replaced by a second, more long-lived mechanism that sustained a much weaker field, through to at least 2. So if you could figure out when the dynamo turned off, then you could distinguish between the mechanisms that have been proposed for the lunar dynamo. That was the purpose of this new paper.
