Precursors to Life Found Near Young Planet

Astronomers using the ALMA telescope discovered ethylene glycol and glycolonitrile—precursors to RNA and DNA—along with water in the dust surrounding a young planet forming near the star V883 Orionis, 1300 light-years from Earth, suggesting the building blocks of life are widespread in the universe.

How do the newly discovered complex organic molecules compare to previous findings on Mars, and what are the potential abiotic explanations for their existence?

The discovery of these long-chain molecules, possibly remnants of fatty acids, suggests a higher complexity than previously understood. While abiotic processes can create such molecules, their existence strengthens the possibility of past life on Mars, warranting further investigation.

What crucial evidence from asteroid Bennu supports the theory of extraterrestrial origins for life's building blocks?

Analysis of asteroid Bennu samples reveals the presence of complex organic molecules, including all five nucleobases and 14 essential amino acids, within salts. These molecules formed in salty water on Bennu's parent body, suggesting the building blocks of life were readily available in the early solar system.

What is the significance of the salts found in the Bennu samples, and what does their presence suggest about the asteroid's history?

The Bennu samples, the first from an asteroid's surface obtained by NASA and the only ones collected from a planetary body in nearly 50 years, reveal thousands of organic molecules. These include 14 proteinogenic amino acids found in Earth life, 19 non-proteinogenic amino acids, and all five biological nucleobases. The asteroid's richness in nitrogen-containing compounds suggests formation in cold, outer solar system regions.

What are the primary challenges in understanding future interpretations of modern-day objects as artifacts?

Paleontologists Sarah Gabbott and Jan Zalasiewicz explore how everyday objects will become artifacts in the future, highlighting the challenges of interpreting objects like smartphones which offer little context to future civilizations. A newly discovered dinosaur species, *Duonychus tsogtbaatari*, is described, possessing large claws used for consuming trees. A partial solar eclipse was visible across parts of North America.

What are the potential future implications of this discovery for the search for extraterrestrial life, particularly concerning the planned ExoMars mission?

This discovery could revolutionize our understanding of past Martian habitability. Future missions, such as the European Space Agency's ExoMars mission launching in 2028, will explore this further, searching for more complex chemistry near potential life traces. The research suggests that Mars might have once harbored conditions suitable for life and that advanced analytical techniques could unveil further evidence.
