It’s always worth being reminded that, in terms of sheer numbers and even mass, humanity is not the dominant form of life on Earth. Putting aside the somewhat bemusing question of whether viruses count as “life” for now, it’s safe to say that the microscopically small members of both the Bacteria and Archaea domains are everywhere.

By braving greater depths, and using increasingly improved scientific techniques, scientists have found life pretty much wherever there is even just a modicum of water, and little else. Forget oxygen and even what we’d think of as nutrients: microorganisms have been found living all over the place; some are suspended within giant crystals deep within suffocating caves in Mexico, and others are sneaking around mine shafts in South Africa, residing in perpetual darkness and bathed in radiation.

Life not just surviving but thriving in such extreme environments are referred to as “extremophilic“, but perhaps that term is a bit of a misnomer. After all, year by year, the number of new species found in these extreme environments rises considerably, which makes their presence in the strangest of nooks ever more expected and, well, normal. Those environments may be inhospitable to life we can see with our eyes, but it’s increasingly becoming clear that we’re in the minority here – fragile, larger lifeforms, wandering about on a planet that doesn’t belong to us as much as we would like to think.

A new study, led by the Deep Carbon Observatory (DCO), really hammers this point home. It reveals not only that the amount of carbon within Earth’s subsurface is between 245 and 385 times greater than the carbon mass of all 7 billion humans, but 70 percent of Earth’s bacteria and archaea live beneath our feet.

Some of them are thriving, others are more inactive and are referred to as “zombies,” but either way, it’s clear that there is a colossal and concealed ecosystem of life hiding underground. The researchers describe the deep biosphere, quite understandably, as a “subterranean Galapagos.”

This landmark Nature Geoscience review, published back in September, represents the culmination of a decade of work. The DCO is an international collaboration of multidisciplinary scientists – featuring over 1,000 scientists spread across 52 countries – who, since 2009, been attempting to quantify the presence of carbon within Earth’s crust.

This is a task of vital importance: carbon influences all parts of Earth’s complex, interconnected systems, from the atmosphere and oceans to, yes, life at the surface, including us. Of course, since life on Earth is carbon-based, working out how much of the stuff there is hidden from view is also a way to roughly work out how much life there is too.

Huge missing puzzle pieces resided deep below, but without having direct access to much of this, identifying it all has proven to be a deeply difficult task. The best scientists can do is a two-fold plan: firstly, they want to find microbial samples that they can use to approximate overall abundances; secondly, they hope to find proxy measurements; things we can directly measure that betray other pieces of information we can’t, like heat, rock geochemistries, water flow and so on.

To wit, the DCO have spent the last decade drilling boreholes up to 2.5 kilometres (1.6 miles) deep into the seafloor, and 5 kilometres (3.1 miles) deep into the continental crust, to see what they could find. After taking countless samples from hundreds of sights all over the world, they have put everything together in this remarkable new paper and, to the best of anyone’s abilities, come up with approximations and mathematical models that explain what lies below.

What they refer to as the “deep biosphere” is roughly 2 to 2.3 billion cubic kilometres (roughly 480 to 551 million cubic miles) in size. That’s obviously a ludicrously high number, so they’ve compared it to being twice the volume of all of Earth’s oceans. Putting it another way, I’ve estimated that it could contain more than 890 billion Great Pyramids of Giza. That space, as it turns out, contains between 15 and 23 billion tonnes (17 to 25 billion tons) of carbon – that upper limit being around 28,600 Golden Gate Bridges.

Within the crust of both the oceans and continents – which, let me remind you is often extremely hot, highly pressurised and exceedingly dark – there is a mind-bogglingly diverse array of life. I’m not just talking about bacteria and archaea here, but Eukaryotes too: more biologically complex critters that, unlike those two aforementioned prokaryotic groups, have membrane-enclosed nuclei and organelles, including the energy-producing mitochondria you may be familiar with. Plants and animals, including us, are eukaryotes.

To be fair, the bacteria and archaea dominate the show down there, and they are phenomenally alien compared to what we see up on the surface. From the biological samples obtained by the DCO, it seems that they have life cycles on near-geological timescales, which is to say that they are extremely long-lived, dwarfing that of anything that sees starlight. At the same time, their genetic diversity is comparable to that of communities on the surface. Although these crypto-communities of microorganisms differ all over the planet, they are ubiquitous – there’s nowhere on Earth that they are not.

The DCO give multiple examples of what they’ve found down there, but stress that most of these many millions have yet to be classified; they even refer to this enigmatic mass as “microbial dark matter.” Saying that, they do give a rather incredible example of what may be the most heat-resistant organism ever discovered: Geogemma barossii, a unicellular beastie that lingers on hydrothermal vents on the sea floor in temperatures of 121°C (250°F).

That’s unlikely to be the most “extreme” form of life we will ever find, mind you. Apart from that fact that it depends what you mean by extreme, the team also stress that they are still just scratching the, er, subsurface even with the world’s most pioneering drilling techniques and modelling in full swing.

“The absolute limits of life on Earth in terms of temperature, pressure, and energy availability have yet to be found,” they say, in an accompanying press release. This also neatly lends itself to the field of astrobiology, whose researchers – searching for life beneath, for example, Mars and Enceladus – are comforted by the notion that even in the most bizarre environments of Earth, life finds a way.

Indeed, there’s still plenty more left to discover, including describing and understanding what exactly it is that’s living down there. Some are thriving, while others are those aforementioned “zombies” – organisms kept in a suspended, barely active state, just about surviving. What exactly is the true proportion of thrivers to survivors? Where to they get their energy from? How does life even move around below there, and what impact does it all have on the surface world?

These questions aside, this study is nothing short of groundbreaking, both literally and scientifically speaking. You can see why some of its contributing authors have given way to poetic, ornate prose when discussing it.

“They are not Christmas ornaments, but the tiny balls and tinsel of deep life look they could decorate a tree as well as Swarovski glass,” Jesse Ausubel, a co-founder of the DCO at The Rockefeller University, surmises. “Why would nature make deep life beautiful when there is no light, no mirrors?”

Of course, the answer is that nature doesn’t care about our perceptions of life. Spacefaring, scientifically advanced great apes at the surface may seem normal to us, but to most of Earth’s life, we’re the freaks: we walk atop the roof of an alien world far more populous than our own.
