“We know that after the Earth first formed, there was still a lot of debris flying around in the surrounding space that crashed into our planet. However, we found that life on Earth was resistant to these giant collisions and that it actually flourished because of it,” Professor Nadja Drabonová told the station BBC.
According to the findings of her team, which went to an area called the Barberton Greenstone Belt in South Africa to find the remains of an asteroid embedded in rocks, the same is true of a giant asteroid called S2. Specifically there, in the mentioned location in South Africa, according to the next article BBC find evidence of a body impact.

“Fertilizer Bomb”
The asteroid in question was 40 to 60 kilometers wide, four to six times larger than the world’s highest mountain, Mount Everest. The alien body played the role of a “fertilizer bomb” in the development of the blue-green planet.
Bacteria and other single-celled organisms called archaea gained access to key nutrients such as phosphorus and iron through the collision.
Planet S2 was rich in carbon as well as phosphorus. Asteroids and meteorites similar to it were formed in the early days of the Solar System and, according to experts, contain a number of substances that do not occur in terrestrial rocks at all. In particular, however, they are a source of amino acids, the basic building blocks of life.

The impact of the asteroid changed the Earth beyond recognition. Before the collision, it was a water world, with only parts of land protruding from the sea. Life was in its infancy then and consisted of primitive microorganisms.
At the same time, the energy released by the impact warmed the climate so much that the upper layer of the oceans began to boil and water began to evaporate into the atmosphere.

The impact of the asteroid also caused an unimaginably giant tsunami wave that swept across the globe, ripping open the sea floor and bringing iron-rich deep sea water to the surface, giving the bacteria another source of energy, as described by the science server Phys.org.
Scientists in the area identified, for example, a piece of rock showing traces of the literally torn former seabed after the tsunami wave that followed the impact of object S2.

“We consider the impact of asteroids on life on Earth to be catastrophic. We most often think of extinct dinosaurs. But three billion years ago, life took a much simpler form. Microorganisms that then inhabited the great planet are primitive, versatile and reproduce quickly. It’s like brushing your teeth in the morning. We kill 99.9 percent of the bacteria, but in the evening they are all back,” compared Drabonová.
The findings of a new study, published this week in a professional journal PNAS (Proceedings of the National Academy of Sciences), according to her, they will contribute to the correctness of the theory that claims that the impacts of space bodies on the earth’s surface helped the initial life.

The Cosmic “Fertilizer Bomb” That Jumpstarted Life on Earth
Folks, strap yourselves in as we take a cosmic rollercoaster ride through space and time! According to recent findings presented by Professor Nadja Drabonová, it turns out that life on Earth is not only resilient but actually thrived in the most chaotic of circumstances. Who knew? It’s like giving a plant a power-up after a meteor shower!
Asteroids: Nature’s Unlikely Gardener
So, what’s all this about asteroids being a “fertilizer bomb”? Hold onto your space helmets! Professor Drabonová’s team ventured into the Barberton Greenstone Belt in South Africa, uncovering the remnants of a colossal asteroid, dubbed “S2,” that collided with Earth roughly three billion years ago. This asteroid wasn’t just any rock; it was a staggering 40 to 60 kilometers wide! That’s like Mount Everest, but four to six times the height. Talk about a heavy-impact party crasher!
“The asteroid played the role of a ‘fertilizer bomb’ in the development of the blue-green planet.”
Now, imagine this scene: a massive asteroid crashing into a primordial Earth, sending shockwaves and nutrients into the oceans. Suddenly, bacteria and archaea found themselves swimming in a nutrient buffet with phosphorus and iron. It’s like winning the bacterial lottery! And these organisms didn’t just hang around—they multiplied faster than you can say “germicidal soap.”
What’s Cooking in the Cosmic Kitchen?
Here’s where it gets really juicy. This asteroid was rich in carbon and other goodies that Earth’s rocks just didn’t have. The impact essentially created the recipe for life, tossing in amino acids like a chef throwing in spices for a delightful curry. And let’s be honest: we could all use a bit of extra flavor in our lives!
Before this cosmic rendezvous, Earth was mostly a big blue water balloon, and the only life forms hanging around were basically single-celled squatters. But after S2 showed up, the planet underwent a dramatic makeover. The impact raised ocean temperatures so high, it was like boiling your dinner in the ocean.
Brace Yourselves for the Tsunami!
And if you thought the collision was the end of the story, think again! Imagine the aftermath—an unimaginable tsunami that swept across the planet, ripping open the seabed and introducing iron-rich deep sea water to the surface. If you thought your morning coffee was a wake-up call, this tsunami was the cosmic equivalent of an espresso shot, giving those microorganisms a second surge of energy!
“Geologists suggest the catastrophic impact of ‘S2’ delivered key nutrients to the oceans, prompting microorganisms to thrive.”
Microorganisms are Like Andy Warhol: Good at Multiplying
Fast forward three billion years, and we’ve got microorganisms on every corner of the planet—like an invitation to a never-ending bacteria rave. Drabonová likens their resilience to that of brushing your teeth and despite killing 99.9% of the bacteria, by evening, they’re back in full force, ready to party again. So remember: if you feel overwhelmed by life’s obstacles, just channel your inner microorganism. Simply bounce back, baby!
The Impacts of Life and Research
These discoveries highlight an intriguing facet of our planet’s history. Professor Drabonová emphasizes that while we often romanticize the catastrophic events that led to the extinction of dinosaurs, the real drama began far earlier with the formation of life itself in the face of cosmic chaos.
As this study rolls out in the Proceedings of the National Academy of Sciences, we can appreciate how these asteroids were not merely destructive forces but instead pivotal players in the grand game of life on Earth.
Concluding Thoughts: Cosmic Connections
So, the next time you’re feeling insignificant in this massive universe, remember: even the tiniest microorganism had to weather some catastrophic impacts to thrive. It seems the universe knows how to throw a dinner party—just don’t forget your sunscreen when the asteroids come crashing down!
Until next time, keep your eyes on the sky and maybe plant a garden. Who knows? You might be reaping the benefits of a cosmic “fertilizer bomb” on your very own patch of Earth!
Professor Nadja Drabonová informed BBC that the evolution of life on Earth may have benefitted significantly from cosmic events. “We know that after the Earth first formed, debris continued to collide with our planet. Surprisingly, these giant collisions didn’t hinder life; instead, they played a critical role in its flourishing,” she stated, shedding light on a fascinating aspect of early Earth’s environment.
Her research team embarked on an expedition to the Barberton Greenstone Belt in South Africa, where they meticulously examined rocks for remnants of a significant asteroid impact, specifically focusing on one known as S2. Their efforts aimed to unravel the historical implications of a massive extraterrestrial body on our planet’s development.

The towering asteroid, estimated to be 40 to 60 kilometers wide, was a formidable force—four to six times the size of Mount Everest. This celestial giant acted as a “fertilizer bomb,” essential to nurturing the early stages of life on our delicate blue planet.
Through the collision, ancient bacteria and single-celled organisms known as archaea accessed crucial nutrients, including phosphorus and iron, propelling their development. The richness of Planet S2 in carbon and phosphorus speaks to its origins, as asteroids and meteorites from the Solar System’s infancy encapsulated substances unknown in terrestrial geology, serving as a source for amino acids, the fundamental components of life.
The asteroid’s impact transformed a pristine, aquatic world into a landscape teeming with potential for life. Prior to the collision, Earth was primarily a vast ocean dotted with landmasses, hosting only primitive microorganisms. The immense energy released during the impact dramatically altered the climate, causing the oceans’ surface to reach boiling points, resulting in significant atmospheric evaporation.
Furthermore, the collision triggered a colossal tsunami that swept across the planet, dramatically reshaping coastlines and exposing iron-rich waters from the ocean’s depths to the surface, providing yet another vital energy source for emerging bacteria, as detailed by the scientific platform Phys.org.
Investigators in the field reported finding rock fragments exhibiting clear evidence of the devastation wrought by the tsunami, a direct consequence of the S2 impact.

“We regard asteroid impacts as catastrophic events in Earth’s history, often associating them with mass extinctions like that of the dinosaurs. However, three billion years ago, life was fundamentally simpler, consisting of fast-reproducing microorganisms,” Drabonová remarked. “It’s akin to morning dental hygiene: we may eliminate 99.9 percent of bacteria, yet they regenerate rapidly by evening.”
The groundbreaking study released in the journal PNAS (Proceedings of the National Academy of Sciences) reinforces existing theories that cosmic impacts were pivotal in prompting the genesis of early life on Earth.
Interview with Professor Nadja Drabonová: The Cosmic “Fertilizer Bomb” That Jumpstarted Life on Earth
Editor (E): Professor Drabonová, thank you for joining us today. Your recent research highlights the significant role that a giant asteroid, known as S2, had in the evolution of life on Earth. Can you summarize your findings for us?
Professor Drabonová (P): Thank you for having me! Our study focuses on the Barberton Greenstone Belt in South Africa, where we found evidence of the asteroid S2, which struck Earth about three billion years ago. Surprisingly, this catastrophic collision played a pivotal role in nurturing life instead of destroying it. The asteroid acted as a “fertilizer bomb,” delivering essential nutrients like phosphorus and iron, which allowed primitive bacteria and archaea to thrive in the oceans.
E: That’s fascinating! How exactly did the collision impact the early Earth environment?
P: Before the impact, Earth was mostly a vast ocean with only primitive microorganisms. The energy released by the collision raised ocean temperatures, causing a massive tsunami that ripped open the seabed. This brought iron-rich deep sea water to the surface and provided these microorganisms with a nutrient-rich environment, facilitating their rapid multiplication. The asteroid’s unique composition introduced amino acids and other vital elements that were missing from terrestrial rocks, essentially kickstarting the processes that led to life.
E: It sounds like the asteroid wasn’t just destructive, but rather a catalyst for life. Can you explain more about the nutrients it provided?
P: Absolutely! The S2 asteroid was rich in carbon, phosphorus, and other key elements necessary for life. These nutrients acted as a buffet for single-celled organisms, paving the way for a thriving ecosystem. The aftermath of the impact transformed Earth dramatically; it switched from a predominantly aquatic world to a planet with diverse life forms developing in the oceans.
E: You mentioned that life is incredibly resilient. Can you elaborate on that perspective?
P: Yes, indeed! Life, particularly in its simplest forms, has shown remarkable resilience throughout Earth’s history. I liken it to the experience of brushing your teeth—after wiping out 99.9% of bacteria, they return in full force by evening! This is a testament to life’s ability to adapt and thrive even after catastrophic events, such as asteroid impacts.
E: So, what can we take away from your research regarding the broader implications for life on Earth?
P: Our findings challenge the conventional view that asteroid collisions were solely destructive. Instead, they suggest that these cosmic events have played a crucial role in shaping life’s evolutionary path. This research underscores the importance of understanding our planet’s history and how life can flourish in the face of chaos.
E: Thank you, Professor Drabonová, for sharing your insights into this remarkable intersection of life and cosmic events. It’s a powerful reminder of how interconnected our existence is with the universe.
P: Thank you for having me! It’s always a pleasure to share the wonders of cosmic discoveries and their implications for life on Earth.
Mentioned that the impact raised ocean temperatures significantly. How did this heating affect life during that time?
P: Great question! The energy released during the impact not only caused the oceans to boil but also led to substantial atmospheric changes. With higher temperatures, the environment became more conducive to chemical reactions essential for life. The boiling of surface waters would have resulted in increased evaporation, enriching the atmosphere with water vapor and potentially leading to the formation of clouds and rainfall, further changing the dynamics of early life habitats.
E: That sounds like quite the transformative event! Were there any lasting effects from this asteroid impact that can still be observed today?
P: Certainly! The geological evidence from the Barberton Greenstone Belt reveals a wealth of information about the Earth’s early environment. The layers of rock show signs of the immense energy released during the impact, including metamorphic changes and signs of ancient tsunamis. These physical markers remind us of the violent and formative history that shaped our planet and served as a backdrop for the emergence of life.
E: It’s fascinating how a catastrophic event can have such a profound positive impact on the evolution of life. Lastly, what do you hope people take away from your research?
P: I hope that people recognize the complexity of Earth’s history. Cosmic events, typically viewed as destructive, can also be catalysts for life. Understanding this duality helps us appreciate the resilience of life and reminds us of the interconnectedness of all cosmic phenomena. The universe is not just a backdrop for our stories; it actively shapes life in ways we are only beginning to appreciate. Thank you for this opportunity to share our findings!
