NASA just made a major asteroid discovery that suggests alien life exists

by

NASA recently announced research that strengthens the idea of how the building blocks of life are created and distributed throughout the universe. Scientists believe these findings make the existence of life beyond Earth more plausible than previously thought.

Scientists are now studying samples collected by NASA’s OSIRIS-REx mission, which successfully brought material from the asteroid Bennu to Earth in 2023 after collecting it in 2020. Although recent focus has been on comet-asteroid 3I/ATLAS and theories about it, new findings from Bennu are proving to be remarkably significant.

Asteroid Bennu, which is about 500 meters wide, was once considered a potential threat to Earth, with a slight possibility of impact around the year 2180. However, its true importance isn’t its potential danger, but what it can teach us about the beginnings of our solar system. Bennu is like a 4.5-billion-year-old time capsule, and the samples collected from it are changing our understanding of how life started.

Okay, so scientists at Tohoku University just made a pretty cool discovery! They were analyzing a sample from an asteroid, and they found six different kinds of sugars in it – including ribose, which is basically what RNA is built from, and glucose, which is the stuff our bodies use for energy. The really big deal is that this is the first time anyone has definitely found glucose in asteroid material that hasn’t been messed with. It’s like finding the building blocks of life out there in space!

A new study, conducted by Scott Sandford from NASA Ames and Zack Gainsforth of UC Berkeley, discovered an unusual, gummy substance inside a space rock – something never seen before. Scientists think this material developed when Bennu’s original parent asteroid heated up, and it may have played a role in the development of more complex organic molecules that eventually arrived on Earth.

A recent study led by NASA’s Ann Nguyen found a surprisingly large amount of stardust in samples from the asteroid Bennu. Bennu contained six times more of these ancient grains – created in the explosions of dying stars – than any other asteroid studied so far. This suggests Bennu originally formed in a part of the early solar system rich in the leftovers of these stellar events.

New space research ramps up possibility of alien life

Daniel Glavin, a key scientist on the OSIRIS-REx mission, believes these discoveries increase the possibility of life existing elsewhere. This isn’t because Bennu itself shows any signs of life, but because it demonstrates that the fundamental components needed for life were widely available throughout the universe.

According to Glavin, the essential chemical building blocks for life were found throughout the entire solar system, from its farthest reaches to near Earth. This widespread presence suggests that life could have originated not only on Earth, but also on places like Mars, Europa, and other locations in the outer solar system, making him hopeful about the possibility of life beyond our planet.

Surprisingly, researchers didn’t discover deoxyribose, the sugar found in DNA. They found ribose instead, which strengthens the idea that life started with simpler RNA molecules before DNA even existed – a concept known as the “RNA world” hypothesis.

The building block ribose was found, but not deoxyribose, which is essential for DNA. This hints that RNA might have been more common than DNA in the early solar system, lending support to the idea that life could have begun with RNA, not DNA.

“Maybe the origin of life was just a single strand of RNA,” Glavin said.

Overall, the analysis of asteroid Bennu supports the theory that asteroids brought the building blocks of life to Earth when the planet was still forming, potentially seeding it with the ingredients necessary for life to emerge.

Glavin expressed growing optimism about the possibility of discovering life outside of Earth, potentially even within our solar system.

This news comes after NASA announced earlier this year that they’d found the strongest evidence yet of past life on Mars. As more discoveries are made, the conversation is changing – it’s no longer about if aliens exist, but when we might find them.
