2014 in science List of years in science. NASA scientists report the possible beginning of a new moon, within the A Ring, of the. A computer simulation by the MD Anderson Cancer Center predicts that on.The Moon’s real age, and creation from the collision of Earth and Theia, finally confirmed (Updated)Updated June 6: Another similar study, published today in Science, appears to confirm that the Moon was created when the planet Theia struck Earth 4. Previous studies had failed to find evidence of Theia in lunar rock samples — but now a more thorough analysis has discovered material of alien origin that lines up with the Theia- Earth giant impact hypothesis. The original story remains below. Original story. A new study has determined with 9. Moon was formed 9. Solar System. This pegs the Moon as being a lot younger than we previously thought — and, perhaps more importantly, that our fair Earth’s development was rather tardy, taking took a lot longer to form than we previously thought. The study also confirms that the Moon was created when a Mars- sized planet (often called Theia) collided with Earth some 4. As always with new data like this, it actually poses more questions than it answers — but that’s why we love science so much, right? Historically, all attempts at aging the Moon have revolved around radiometric dating — i. Radiometric dating is pretty good, but it has fairly limited accuracy over a time span of billions of years (previous attempts at dating the age of the Moon have ranged from 3. Solar System was born). This new method, devised by a worldwide group of researchers, takes a very different approach. It’s fairly complex, but I’ll try to boil it down for you. The Daily Show is an Emmy and Peabody Award-winning program that looks at the day's top headlines through a sharp, reality-based lens. NEW TIMERS; NOTHIN'S EASY; NOTHING TO REPORT; See all SHORT FORM. Over the years, we here at Gizmodo have provided you many, many examples of scientifically backed evidence to shove in the faces of lunar landing conspiracists. But this one might be the most convincing of all: Engineers used. The impact of Earth and Theia, as depicted by a NASA artist. What you probably didn’t know is that there is a class of elements called siderophiles (literally “iron- loving” in Greek), including platinum, gold, and iridium, that readily dissolve in iron (either as a solution or molten). These siderophiles naturally tend to sink towards the core of the Earth, where there’s lots of iron — which explains why these elements so rarely occur in the Earth’s crust (where we do all of our mining). Anyway, the theory (which is very well supported by this point) is that Theia’s collision drove almost all of these siderophiles into the Earth’s core. The theory postulates that the crust was so stripped of these rare elements that almost all of the siderophiles that we find today must’ve come from later, smaller impacts (asteroids).

Solar System came into existence. Well, it’s always interesting to know more about how the Solar System and its planets formed, as it can inform us about the science and geology of other local planets, and also about other planets elsewhere in the universe. In this case, the study highlights that the Earth did not finish forming until around 1. Sun — but Mars appears to have taken only a few million years to form completely. Why is there such a huge disparity, and is such a disparity common, or is Earth (or Mars) special? There is now a lot of attention on Venus, which is very similar in size and composition to Earth — but because no asteroids from Venus have ever landed on Earth, and because we haven’t sent a lander there, we don’t know how long it took to form. We also believe that huge impacts, like the Earth- Theia event, were pretty common back then — but if so, why doesn’t Venus have a moon? Also, just in case you were wondering, there are other theories of how the Earth and Moon came to be. Most of them are a little silly, such as the Earth spinning fast enough that its molten surface was flung into space by centrifugal force, where it cooled into the Moon. A better theory, which I quite like, is that the Earth and Moon were both created at the same time, by a giant collision of two planets, which ejected some debris that became the Moon, and then re- collided (more gently this time) to coalesce into Earth. This quite neatly explains why the Earth and Moon are “atomically identical” when it comes to the presence of various elemental isotopes.
