Scientists Claim to Have Found The First Known Alien Protein

In summary, scientists have discovered a new protein, called hemolithin, in a meteorite that fell to Earth 30 years ago. This protein has a similar structure to proteins found on Earth but has a different deuterium to hydrogen ratio, suggesting an extraterrestrial origin. This finding could potentially support the theory of Panspermia, where life on Earth may have been seeded by proteins from space. This discovery has also sparked discussions about the origin of life and the possibility of finding evidence of life made of similar precursor proteins in space.

I think this is important not just for the extraterrestrial part but it can help explain how life starts on planets through Panspermia.

A new discovery could be a clue for us to see if life could emerge elsewhere in the Solar System. Using a new analysis technique, scientists think they have found an extraterrestrial protein, tucked inside a meteorite that fell to Earth 30 years ago.

If their results can be replicated, it will be the first protein ever identified that didn't originate here on Earth.

"This paper characterises the first protein to be discovered in a meteorite," the researchers wrote in a paper uploaded to preprint server arXiv. Their work is yet to be peer reviewed, but the implications of this finding are noteworthy.

The researchers are calling this newly discovered protein hemolithin. While hemolithin is structurally similar to terrestrial proteins, its ratio of deuterium to hydrogen was not matched by anything on Earth. It is, however, consistent with long-period comets.

This suggests, the researchers argue, that the structure they have identified as protein is of extraterrestrial origin, and possibly formed in the proto-solar disc, over 4.6 billion years ago.

This could really be groundbreaking. If we find proteins that can develop in space, that would be a really good narrative as to how life started on Earth and why we might find microbial life on other planets.

If proteins form in space, then you can have a situation where simple replicators form on Earth then these early proteins from space seed a planet. These proteins then are replicated by the replicators. There's then a jump to digital information and DNA.

I accept an Intelligent Design interpretation of evolution but I wanted to ask what do people think about this narrative vs. Abiogenisis?

Maybe we should look for evidence of life made of these precursor proteins that formed in space.

Related to Scientists Claim to Have Found The First Known Alien Protein

1. What is the significance of scientists claiming to have found the first known alien protein?

The discovery of the first known alien protein is significant because it could potentially provide evidence for the existence of extraterrestrial life. It also opens up new possibilities for studying the origins of life on Earth and beyond.

2. How did scientists find this alien protein?

The protein was found in a meteorite that crashed into Earth in 2019. Scientists used advanced techniques to analyze the meteorite and identified the presence of a unique protein that does not match any known proteins on Earth.

3. Is this protein confirmed to be of extraterrestrial origin?

While the protein was found in a meteorite, it is not yet confirmed to be of extraterrestrial origin. Further research and analysis is needed to determine its exact origins and if it is truly of alien origin.

4. What implications does this discovery have for the search for extraterrestrial life?

This discovery opens up new possibilities for the search for extraterrestrial life. It suggests that life may exist beyond Earth and that there could be other forms of life that are vastly different from what we know on our planet.

5. What are the next steps for scientists in studying this alien protein?

Scientists will continue to analyze the protein and conduct further research to determine its exact composition and structure. They will also search for other potential alien proteins and continue to study the meteorite for any other clues about the origins of life on Earth and beyond.
