The discovery adds to evidence that suggests life’s precursors came from space



A 2-gram chunk from this rock — a piece of the meteorite that fell near Murchison, Australia, in 1969 — contains two crucial components of DNA and RNA now identified for the first time in an extraterrestrial source, researchers say.

More of the ingredients for life have been found in meteorites.

Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report April 26 in Nature Communications.

These “nucleobases” — adenine, guanine, cytosine, thymine and uracil — combine with sugars and phosphates to make up the genetic code of all life on Earth. Whether these basic ingredients for life first came from space or instead formed in a warm soup of earthly chemistry is still not known (SN: 9/24/20). But the discovery adds to evidence that suggests life’s precursors originally came from space, the researchers say.

Scientists have detected bits of adenine, guanine and other organic compounds in meteorites since the 1960s (SN: 8/10/11, SN: 12/4/20). Researchers have also seen hints of uracil, but cytosine and thymine remained elusive, until now.

“We’ve completed the set of all the bases found in DNA and RNA and life on Earth, and they’re present in meteorites,” says astrochemist Daniel Glavin of NASA’s Goddard Space Flight Center in Greenbelt, Md.

A few years ago, geochemist Yasuhiro Oba of Hokkaido University in Sapporo, Japan, and colleagues came up with a technique to gently extract and separate different chemical compounds in liquified meteorite dust and then analyze them.

“Our detection method has orders of magnitude higher sensitivity than that applied in previous studies,” Oba says. Three years ago, the researchers used this same technique to discover ribose, a sugar needed for life, in three meteorites (SN: 11/22/19).

In the new study, Oba and colleagues combined forces with astrochemists at NASA to analyze one of those three meteorite samples and three additional ones, looking for another type of crucial ingredient for life: nucleobases.

The researchers think their milder extraction technique, which uses cold water instead of the usual acid, keeps the compounds intact. “We’re finding this extraction approach is very amenable for these fragile nucleobases,” Glavin says. “It’s more like a cold brew, rather than making hot tea.”

With this technique, Glavin, Oba and their colleagues measured the abundances of the bases and other compounds related to life in four samples from meteorites that fell decades ago in Australia, Kentucky and British Columbia. In all four, the team detected and measured adenine, guanine, cytosine, uracil, thymine, several compounds related to those bases and a few amino acids.

They been knew this

History repeats itself

They "destroy" it, hide it

Bring it back out like if it was new info

Yup they doing all this to gear up for the fake alien invasion they got in their back pocket by way of Pbb

We def came from space

Can we all agree that maybe WE are the extraterrestrials, and what we think are aliens have finally discovered life on another planet and have been discreetly monitoring us?

Religious cucks come get this steaming pile of

This isn't saying that humans are aliens.

Tlatoani said This isn't saying that humans are aliens.

Has to be how life started. Organisms from other planets. I mean you had billions of years and perfect conditions for it to happen.
Life is chance

this is probably the result of astronauts fu*king in space and tossing the condom out in space

Just open up the window and throw it into space?

Thread about to turn into an anti-religion seminar.

I read somewhere that 85% of our bodies have components that are not of this planet, or something like that. I’ll try to find the article and post it.

This isn't new

The ancient esoterists and occultism and magi orders always said our life was coded within in the "stars"

The phrase like “As above, so below” is used by writers and astrologers alike to explain why and how the world works.

The concept implies that the visible stars in the sky are linked to life on earth, and that the microcosm and the macrocosm are connected. The human world is related to the larger universe. Everything is connected

Don’t the pyramids align perfectly with certain stars? Interesting

Two words homogenous chirality.

You're too ignorant to even understand what that means.

You're basically saying AutoZone workers and Tesla engineers are the same thing.

You're saying a pile of wood and nails is a house.

No sh*t we live in it bro

drop it in a water based planet, give it a few million years to cook you got another civilization, considering millions of earth years are still minute when it comes to time on a universal scale, it would be foolish to think we are only life...

n*ggas basically an alka seltzer...

Doesn't make us aliens just means the ingredients to make like come from space you gotta start from something..

Even religious texts state man was made from clay/earth/meteorite whatever so in essence it's not wrong...
