The Japan Space Exploration Agency went into space in 2014 to collect samples from asteroids. Hayabusa2 The spacecraft made a discovery that wouldn’t be enough to just say “big.” Nucleobases, one of life’s most basic building blocks, were found in the sample sent to Earth by the spacecraft from the asteroid Ryugu.

One of the four bases in the RNA structure in a soil sample taken from the asteroid 336 million kilometers away. uracil found it. In addition to uracil, it forms vitamin B3. your hope was also discovered.

Could these be materials the spacecraft accidentally transported from Earth or collected from the environment when the capsule entered Earth?

• The capsule in which the monsters were brought to Earth.

Astrochemist Yasuhiro Oba of Hokkaido University stated that nucleobases and vitamins have previously been found in carbon-rich asteroids. The samples obtained from these discoveries on exposure to the terrestrial environment. He also said that there are always doubts.

But the latest discovery, according to Oba, leaves no room for these doubts. The Hayabusa2 spacecraft also used thermal insulation to ensure that the samples it collected were not contaminated in any way. in special sealed capsules Send it out into the world.

So what does the presence of nucleobases and vitamins in an asteroid mean?

• Formation of the Earth and Moon.

One of the most widely accepted theories about the origin of life on Earth is that the building blocks of life, caused by collisions in the formation of our planet direction.

Our Earth and other planets in our system orbited the sun about 4.6 billion years ago, when our sun was still a young star. due to numerous collisions of dust and asteroid particles happened as it grew.

The theory is that the building blocks of life on Earth could also have come from deep space, caught in the sun’s gravity and eventually because these asteroids collide with other particles was brought.

• Monsters from Ryugu to Earth.

Nucleobases and vitamins, also found in Ryugu and other asteroids, a proof of this theory is valued as. In other words, life on Earth may have taken on its current form thanks to building blocks that actually came from the depths of space and traveled a long time.

To prove this theory, it is still more evidence is needed. As part of NASA’s ongoing OSIRIS-REx mission, new samples from the asteroid Bennu will reach Earth this year. These examples are expected to provide new details on the topic.

Ryugu also recently hosted another discovery:
