Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar
space. The discoveries indicate that some basic chemicals that are key steps on the way to life may have formed on dusty ice grains floating between
This is some really cool stuff.
It's not 100% yet, but it is another step in the right direction I think.
The molecules believed to form the amino acids that make-up DNA have been found in a gas cloud near the center of the Milky Way. This discovery aside,
being able to identify molecules on grains of ice 25,000 light years away is flat out amazing. Regardless of where you believe life originated.
Maybe it's just me, but I get excited about this type of thing.
The Green Bank Telescope and some of the molecules it has discovered.
Previously, scientists thought such processes took place in the very tenuous gas between the stars. The new discoveries, however, suggest that the
chemical formation sequences for these molecules occurred not in gas, but on the surfaces of ice grains in interstellar space. "We need to do
further experiments to better understand how these reactions work, but it could be that some of the first key steps toward biological chemicals
occurred on tiny ice grains," Remijan said.
I think this also ties in well with this thread from about a year and a half ago. Building
Blocks of DNA Found in Meteorites from Space
Past research had revealed a range of building blocks of life in meteorites, such as the amino acids that make up proteins. Space rocks just like
these may have been a vital source of the organic compounds that gave rise to life on Earth.
Were the meteors seeded by ice particles in the gas clouds?
Either way it's very interesting stuff and things.
