ESA Finds Amino Acids on Comet

Ingredients regarded as crucial for the origin of life on Earth have been discovered at the comet that ESA’s Rosetta spacecraft has been probing for almost two years.

They include the amino acid glycine, which is commonly found in proteins, and phosphorus, a key component of DNA and cell membranes.

Scientists have long debated the important possibility that water and organic molecules were brought by asteroids and comets to the young Earth after it cooled following its formation, providing some of the key building blocks for the emergence of life.

While some comets and asteroids are already known to have water with a composition like that of Earth’s oceans, Rosetta found a significant difference at its comet – fuelling the debate on their role in the origin of Earth’s water.

But new results reveal that comets nevertheless had the potential to deliver ingredients critical to establish life as we know it.

Shit! I didn't know that they were playing. Tongue

This is also why I love science, discoveries, discoveries, discoveries. Not old stories just made up because, ignorant.

Thanks for this post. Smile

Rocket, I posted this link a couple months ago but you were not hanging here at the time. Here it is again. Maybe you'll find it interesting.

He is deformed, crooked, old, and sere,
Ill-fac’d, worse bodied, shapeless every where;
Vicious, ungentle, foolish, blunt, unkind,
Stigmatical in making, worse in mind.

I have read that. But I do find it more than a little interesting!!

Thanks for pointing me to it, anyway! Smile

It's only a matter of time before we find tardigrades on one.

In a good way or a bad way?

In a bad way. Tardigrades come from a relatively "advanced" phylum, in that the first 3/4ths of the history of life on earth was dominated by single-celled organisms, and then colonial mats, and then blobby things... the Tardigrades did not appear on earth until the Cambrian roughly 530 MYA, though we think we've pinpointed their pre-Cambrian ancestors, Opabinia.

The point is that finding them in comets (supposedly extant from the formation of our solar system) would mean the prebiotic materials got there along with the animals that flew up there, somehow, and would essentially reset our research to Square One.
