Alien life may be hidden in the moon, which acts like a fishing net. to hold interstellar objects, says Harvard scientist
- Harvard Scientists Say Our Own Moon Can Hold Clues to Alien Life
- Impacts of interstellar objects may have deep space embedded clues
- The moon's surface would probably contain these clues for billions of years, he says.
Extraterrestrial proof of life may be much closer to home than most people think, according to a Harvard scientist.
In an article published in Scientific american, theoretical physicists and Harvard professor Abraham Loeb states that our own moon can be a "fishing net" for alien life.
"The idea is to consider the moon's surface as a fishing net for interstellar objects collected over time and potentially provide life building blocks from habitable environments around other stars," writes Loeb in Scientific American.
Because the moon is geologically inactive, Loeb says the surface is likely to retain any intriguing interstellar clues brought by asteroid or some other astrophysical source, rather than burying evidence deep within the lunar surface.

Objects collected from the moon's surface would probably extend billions of years ago, making the moon a sort of 'mailbox', as he says, for objects flying around our solar system.
While most of these impacts are likely to be the result of objects originating from our solar system, recent evidence shows that interstellar travelers around our neck of the galaxy may be much more common than previously thought.
Recently, astronomers have identified the second known interstellar object entering our solar system – a comet called 2l / Borisov – that will be visible through telescopes for up to a year.
In 2017, researchers identified Oumuamua, the first – a mysterious cigar-shaped projectile, a formally named object resembling a comet and an asteroid, although it does not conform to many of the other defining characteristics commonly associated with these objects.

Not only do these objects foreshadow extraterrestrial dirt on the moon, Loeb says, but studying them can also help inform scientists exactly how much may be lurking on the surface.
"With this calibration in hand, it is possible to calculate the amount of interstellar material that has been collected on the moon's surface throughout its history," he writes.
Loeb says that based on current measurements of the flow – amount of energy – of interstellar objects, the lunar surface can contain up to 30 parts per million lunar surface material.
"Amino acids, which serve as the building blocks of" life as we know it, "can reach some parts by a hundred billion," says Loeb.
This render (pictured above) shows a concept of what a base may look like on the lunar surface. From here, humans would be able to explore the lunar surface.
Micro-fossils of extinct alien life, similar to the 3.4 billion-year versions found on Earth, are also a distinct possibility, he says.
Of course, even more exciting than bits of interstellar matter would be the prospect of a more open life signal in other parts of the universe.
"Even more exciting would be to find traces of technological equipment that collided with the lunar surface a billion years ago, worth a letter from an alien civilization saying," We exist, "Loeb wrote.
"Without checking our mailbox, we would never know this message would arrive."
With the potential for a lunar base to be built by the US or China, Loeb says these discoveries may be coming.
WHAT IS NASA'S ARTEMIS MISSION TO THE MOON?
Artemis was the twin sister of Apollo and moon goddess in Greek mythology.
NASA has chosen her to personify her way back to the moon, which will see astronauts return to the lunar surface by 2024 – including the first woman and the next man.
Artemis 1, formerly Exploration Mission-1, is the first in a series of increasingly complex missions that will allow human exploration on the Moon and Mars.
Artemis 1 will be the first integrated flight test of NASA's space exploration system: the Orion spacecraft, the Space Launch System (SLS) rocket and ground systems at the Kennedy Space Center in Cape Canaveral, Florida.
Artemis 1 will be an unmanned flight that will provide a basis for exploration of deep human space and will demonstrate our commitment and ability to extend human existence to the moon and beyond.
During this flight, the spacecraft will launch the most powerful rocket in the world and fly farther than any human-built spacecraft ever flew.
He will travel 450,000 kilometers from Earth, thousands of kilometers beyond the moon, during a three-week mission.

Orion will remain in space longer than any spacecraft for astronauts without docking in a space station and will return home faster and warmer than ever.
With this first exploration mission, NASA is leading the next steps in deep-space human exploration, where astronauts will build and begin testing the near-moon systems needed for lunar surface missions and exploration to destinations further away from Earth, including Mars.
They will take the team on a different trajectory and test Orion's critical systems with humans on board.
The SLS rocket will go from an initial configuration capable of sending over 26 tons to the moon, to a final configuration that can send at least 45 tons.
Together, Orion, SLS and Kennedy ground systems can meet the most challenging deep space cargo crew and mission needs.
Eventually, NASA seeks to establish a sustainable human presence on the moon by 2028 as a result of the Artemis mission.
The space agency hopes that this colony will discover new scientific discoveries, demonstrate new technological advances, and lay the foundation for private companies to build a lunar economy.
