A second-rack bagel that's nearly first-rack. Tasty stuff.
Summary
NASA's Curiosity rover has discovered more than 20 organic compounds in Martian rock samples from Gale Crater, including nitrogen-bearing molecules structurally similar to chemicals that help form DNA. This marks the first time such a chemical experiment has been conducted on another planet, suggesting Mars can preserve complex organic material for billions of years. The findings indicate the planet may have preserved molecules that could point to evidence of past life.
Key quotes
· 5 pulledNASA's Curiosity rover has found a new set of organic molecules on Mars, including compounds scientists say are linked to the building blocks of life.
The discovery comes from a chemical experiment carried out for the first time on another planet and suggests Mars can preserve complex organic material for billions of years.
Scientists say the rover identified more than 20 organic compounds in rock samples collected from Gale Crater, a former lake bed where water once existed.
Among them was a nitrogen-bearing molecule with a structure similar to chemicals that help form DNA, something never found before on Mars.
The findings suggest Mars can preserve the kind of molecules that could point to proof that life once existed on the planet.
