Murchison meteorite, this is the oldest material found on Earth to date. It fell in Australia in 1969 near Murchison, Victoria. It is over 7 billion years old.

This is one of the oldest rocks in existence.

It is approximately 4,600,000,000 years old and existed before the Earth itself had completely formed. It is called the Murchison Meteorite.

The Murchison meteorite is a meteorite that fell in Australia on 28 September 1969 near Murchison, Victoria.

It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds.

Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall, the Murchison meteorite is one of the most studied of all meteorites.

Oh snap so what’s your favorite meteorite??? Both type and specific rock! ;)

I have a soft spot for Iron meteorites, cause they're the ones I did my PhD on. I love a good Widmanstatten pattern.

Iron meteorites come from the core of (destroyed) differentiated extraterrestrial planetary bodies. They're called Iron meteorites but are actually an alloy of Iron and Nickel. The amount of Nickel dictates the mineral phase: kamacite is poor in Ni, taenite is richer. The co-existence of both phases will create the Widmanstatten pattern.

Pallasites are quite lovely too.

Pallasite are thought to come from the boundary between the core and the mantle of differentiated extraterrestrial bodies. the Iron-Nickel metal part comes from the core, while the big olivine crystals come from the mantle.

Fun fact: meteorites are the only way we know what the Earth's core and core/mantle boundaries are made of, cause it's actually easier to get a rock from far away in the Solar System than dig 3000 km into the ground.

I don't have a specific rock that. There's the ones I've studied, like Copiapo or Mont Dieu. There's the famous ones among cosmochemists: Canyon Diablo, Murchison, Allende, etc...

(Meteorites are named after the place they're found at. If it's a desert, they get a matricule. ex: NWA + number. NWA = North West Africa, for all the ones found in the Sahara desert)

Two meteorites are providing a detailed look into outer space If you’ve ever seen a shooting star, you might have actually seen a meteor on its way to Earth. Those that land here are called meteorites and can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Today, scientists report some of the most detailed analyses yet of the organic material of two meteorites. They’ve identified tens of thousands of molecular “puzzle pieces,” including a larger amount of oxygen atoms than they had expected. The researchers will present their results at the spring meeting of the American Chemical Society (ACS). ACS Spring 2023 is a hybrid meeting being held virtually and in-person March 26–30, and features more than 10,000 presentations on a wide range of science topics. Previously, the team led by Alan Marshall, Ph.D., investigated complex mixtures of organic materials found on Earth, including petroleum. But now, they are turning their attention toward the skies — or the things that have fallen from them. Their ultra-high resolution mass spectrometry (MS) technique is starting to reveal new information about the universe and could ultimately provide a window into the origin of life itself. “This analysis gives us an idea of what’s out there, what we’re going to run into as we move forward as a ‘spacefaring’ species,” says Joseph Frye-Jones, a graduate student who is presenting the work at the meeting. Both Marshall and Frye-Jones are at Florida State University and the National High Magnetic Field Laboratory. Thousands of meteorites fall to Earth every year, but only a rare few are “carbonaceous chondrites,” the category of space rock that contains the most organic, or carbon-containing, material. One of the most famous is the “Murchison” meteorite, which fell in Australia in 1969 and has been studied extensively since. A newer entry is the relatively unexplored “Aguas Zarcas,” which fell in Costa Rica in 2019, bursting through back porches and even a doghouse as its pieces fell to the ground. By understanding the organic makeup of these meteorites, researchers can obtain information about where and when the rocks formed, and what they ran into on their journey through space. To make sense of the complicated jumble of molecules on the meteorites, the scientists turned to MS. This technique blasts a sample apart into tiny particles, then basically reports the mass of each one, represented as a peak. By analyzing the collection of peaks, or the spectrum, scientists can learn what was in the original sample. But in many cases, the resolution of the spectrum is only good enough to confirm the presence of a compound that was already presumed to be there, rather than providing information about unknown components. This is where Fourier-transform ion cyclotron resonance (FT-ICR) MS comes in, which is also known as “ultra-high resolution” MS. It can analyze incredibly complex mixtures with very high levels of resolution and accuracy. It’s especially well suited for analyzing mixtures, like petroleum, or the complex organic material extracted from a meteorite. “With this instrument, we really have the resolution to look at everything in many kinds of samples,” says Frye-Jones. The researchers extracted the organic material from samples of both the Murchison and Aguas Zarcas meteorites, then analyzed it with ultra-high resolution MS. Rather than analyzing only one specific class of molecules at a time, such as amino acids, they chose to look at all soluble organic material at once. This provided the team with more than 30,000 peaks for each meteorite to analyze, and over 60% of them could be given a unique molecular formula. Frye-Jones says these results represent the first analysis of this type on the Aguas Zarcas meteorite, and the highest-resolution analysis on the Murchison one. In fact, this team identified nearly twice as many molecular formulas as previously reported for the older meteorite. Once determined, the data were sorted into unique groups based on various characteristics, such as whether they included oxygen or sulfur, or whether they potentially contained a ring structure or double bonds. They were surprised to find a large amount of oxygen content among the compounds. “You don’t think of oxygen-containing organics as being a big part of meteorites,” explained Marshall. The researchers will next turn their attention to two far more precious samples: a few grams of lunar dust from the Apollo 12 and 14 missions of 1969 and 1971, respectively. These samples predate Marshall’s invention of FT-ICR MS in the early 1970s. Instrumentation has come a long way in the decades since and is now perfectly poised to analyze these powders. The team will soon compare their results from the meteorite analyses to the data they obtain from the lunar samples, hoping to learn more information about where the moon’s surface came from. “Was it from meteorites? Solar radiation? We should be able to soon shed some light on that,” says Marshall.

All of the bases in DNA and RNA have now been found in meteorites. The discovery adds to evidence that suggests life’s precursors came from space

A 2-gram chunk from this rock — a piece of the meteorite that fell near Murchison, Australia, in 1969 — contains two crucial components of DNA and RNA now identified for the first time in an extraterrestrial source, researchers say.

Perth, Australia (SPX) Dec 22, 2023 Analysis of organic compounds - called polycyclic aromatic hydrocarbons (PAHs) - extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas of space between stars rather than in hot regions near stars as was previously thought. The findings open new possibilities for studying life beyond Earth and the chemistry of objects in space.

"These results prove that prebiotic sugar synthesis may have overlaps with extant biochemical pathways." Given that sugars are ubiquitous in modern metabolism, the proposed reaction network could have been important for the emergence of the first life-like systems.

The findings of this study are important in the context of astrochemistry and astrobiology. Aldonates were found abundantly in the Murchison meteorite, a famous carbonaceous meteorite that fell to Earth in 1969.

In contrast, the canonical carbohydrates found in modern biological systems were absent in it. This implies that aldonates can form and accumulate in extraterrestrial conditions, and the present study suggests that they could play an important role in the origin of the building blocks of life.

All life on this planet shares a left-chirality. We may have figured out why…

"The idea that homochirality may have originated in space was suggested after AAs were found in the Murchison meteorite that fell in Australia in 1969," explains Dr. Shoji. Curiously enough, in the samples obtained from this meteorite, each of the L-enantiomers was more prevalent than its D-enantiomer counterpart. One popular explanation for this suggests that the asymmetry was induced by ultraviolet circularly polarized light (CPL) in the star-forming regions of our galaxy.

Uma hipótese é que os meteoritos entregaram aminoácidos – os blocos de construção da vida – ao nosso planeta. Agora, pesquisadores relatando na ACS Central Science mostraram experimentalmente que os aminoácidos poderiam ter se formado nesses primeiros meteoritos a partir de reações conduzidas por raios gama produzidos dentro das rochas espaciais. Desde que a Terra era um planeta recém-formado e estéril, os meteoritos foram lançados pela atmosfera em alta velocidade em direção à sua superfície. Se os detritos espaciais iniciais incluíssem condritos carbonáceos – uma classe de meteoritos cujos membros contêm quantidades significativas de água e pequenas moléculas, como aminoácidos – então poderiam ter contribuído para a evolução da vida na Terra. No entanto, a fonte de aminoácidos em meteoritos tem sido difícil de identificar. Em experimentos de laboratório anteriores, Yoko Kebukawa e colegas mostraram que reações entre moléculas simples, como amônia e formaldeído, podem sintetizar aminoácidos e outras macromoléculas, mas água líquida e calor são necessários. Elementos radioativos, como o alumínio-26 ( 26Al) — que se sabe ter existido nos primeiros condritos carbonáceos — liberam raios gama, uma forma de radiação de alta energia, quando decaem. Este processo poderia ter fornecido o calor necessário para fazer biomoléculas. Então, Kebukawa e uma nova equipe queriam ver se a radiação poderia ter contribuído para a formação de aminoácidos nos primeiros meteoritos. Os pesquisadores dissolveram formaldeído e amônia em água, selaram a solução em tubos de vidro e depois irradiaram os tubos com raios gama de alta energia produzidos a partir do decaimento do cobalto-60. Eles descobriram que a produção de α-aminoácidos, como alanina, glicina, ácido α-aminobutírico e ácido glutâmico, e β-aminoácidos, como β-alanina e ácido β-aminoisobutírico, aumentou nas soluções irradiadas como o total dose de raios gama aumentada. Com base nesses resultados e na dose esperada de raios gama do decaimento de 26Al em meteoritos, os pesquisadores estimaram que levaria entre 1.000 e 100.000 anos para produzir a quantidade de alanina e β-alanina encontrada no meteorito Murchison, que caiu na Austrália em 1969. Este estudo fornece evidências de que reações catalisadas por raios gama pode produzir aminoácidos, possivelmente contribuindo para a origem da vida na Terra, dizem os pesquisadores.
