Hunted Treasure Turns Out to be a Piece of the Universe
Imagine stumbling upon a heavy, red rock while searching for gold. That’s exactly what happened to David Hole in 2015 near Melbourne, Australia. Convinced he’d struck it rich, Hole spent years trying to crack open the mysterious stone. Little did he know, he’d unearthed a relic from the cosmos, a 4.6 billion-year-old meteorite.
"The rock looked like it had been carved and had dents," remarked Dermot Henry, a geologist at the Museum of Victoria, years later. “It was formed when it passed through the atmosphere, melted on the outside, and the atmosphere shaped it."
Frustrated by his inability to break the rock, Hole brought it to the museum for identification. Henry, who had examined thousands of rocks in his 37 years at the museum, had only encountered two genuine meteorites. Hole’s find was one of them.
"If you see a rock on Earth like this, and pick it up, it shouldn’t be that heavy," explained Bill Birch, another geologist at the museum.
Scientists dubbed the meteorite "Maryborough," after the nearby town where it was discovered. Weighing in at a hefty 17 kilograms (37 pounds), a diamond saw was needed to finally break a small piece off. Analysis revealed it to be an H5 ordinary chondrite, rich in iron and containing tiny, crystallized mineral droplets called chondrules.
“Meteors provide the most affordable form of space exploration," Henry explained. "They take us back to the past, providing clues about the age, formation, and chemistry of our Solar System (including Earth).”
He continued, “Some even give us a glimpse into the insides of planets. In some meteorites, we find ‘stardust’ that is even older than our solar system, showing us how stars form and evolve to create the elements of the periodic table. Other rare meteorites contain organic molecules like amino acids, the building blocks of life.”
While its exact origin remains a mystery, scientists theorize that the meteorite originated in the asteroid belt between Mars and Jupiter. It was likely dislodged by collisions and eventually plunged towards Earth.
Carbon dating suggests the meteorite has been on Earth for a few hundred to a thousand years, possibly linked to meteor sightings between 1889 and 1951.
For scientists, the Maryborough meteorite is far more valuable than any gold nugget. It is the 17th recorded meteorite in the state of Victoria and the second largest chondritic meteorite, after a 55 kilogram (121 pound) specimen found in 2003. “It’s only the 17th meteorite found in Victoria, when thousands of gold nuggets have been found," Henry stated. "In that sense, it’s an extraordinary discovery."
This isn’t the first time a meteorite has taken its time to reach a museum. In a captivating story from 2018, another space rock took 80 years, two owners and a stint as a doorstop before its true identity was revealed.
The Maryborough meteorite serves as a reminder that sometimes the greatest treasures aren’t found in the gold rush, but hidden in plain sight, falling from the stars.

Imagine stumbling upon a heavy, red rock while searching for gold. That’s exactly what happened to David Hole in 2015 in Australia. Little did he know this seemingly ordinary find would turn out to be an extraordinary piece of cosmic history. Years later, analysis revealed the rock to be a rare meteorite, estimated to be **4.6 billion years old** – a fragment from the early formation of our solar system!
To delve deeper into this captivating story, we spoke with Dr. Helena Ramirez, a leading meteorite expert at the Smithsonian National Museum of Natural History.
**WTN:** Dr. Ramirez, the news of David Hole’s find has captivated the world. What makes this meteorite so special?
**Dr. Ramirez:** This meteorite, officially classified as a ureilite, is incredibly valuable for several reasons. Firstly, ureilites are relatively rare, comprising only a small percentage of all meteorites that have been found. Secondly, their age. Being approximately 4.6 billion years old, thay provide invaluable insights into the conditions of our early solar system.
**WTN:** Can you explain why these meteorites offer such a unique window into the past?
**Dr. Ramirez:** Ureilites are thought to originate from the core-mantle boundary of differentiated asteroids. This means they contain materials that were once part of a larger celestial body.By studying their composition, we can learn about the formation and evolution of asteroids, which in turn shed light on the early stages of our solar system.
**WTN:** David Hole’s intention was to find gold. What signs might have alerted him to the fact that he had stumbled upon something more significant?
**Dr. Ramirez:** While the red colour might have been a hint,ureilites can frequently enough resemble other terrestrial rocks. It’s their density and unusual texture that are more telling.
**WTN:** What analysis was conducted on the meteorite to confirm its origin?
**Dr. Ramirez:** A multi-pronged approach was used. Microscopic examination revealed distinct mineral grains characteristic of ureilites.

Isotopic analysis helped determine the meteorite’s age and origin.
**WTN:** This finding raises fascinating questions about the abundance of meteorites on Earth.how common are they truly, and what resources can be gleaned from them?
**Dr. Ramirez:** While meteorites might seem rare,they are constantly falling to Earth. Manny go unnoticed, landing in remote areas or oceans. They provide a wealth of information, not only about the solar system but also about the potential resources that could exist in space.
**WTN:** Dr. Ramirez, thank you for sharing your insights. This astonishing discovery reminds us of the wonders hidden in plain sight and the constant possibilities for scientific discovery.
** This is a truly remarkable find, and it underscores the importance of continued exploration and scientific inquiry. David Hole’s serendipitous discovery has certainly brought a piece of the universe a little closer to home.**
