Curiosity finds diverse organic ‘life’s building blocks’ in Gale Crater—biology not proven amid renewed debate

NASA’s Curiosity rover has detected a diverse mix of organic molecules on Mars, including chemicals regarded as potential building blocks for life’s origins on Earth. Researchers say the findings are compatible with habitability, but the origin of the organics—biological or abiotic—remains uncertain, spurring competing interpretations.

eROSITA disentangles Solar System soft X-ray emission, clarifying its impact on the X-ray sky Using the eROSITA space telescope, MPE researchers have isolated the X-ray glow originating within the Solar System and quantified how it contributes to the observed soft X-ray sky. The result improves interpretation of diffuse X-ray backgrounds and separates local emission from astrophysical sources.

NASA powers down Voyager 1’s LECP instrument to conserve energy and extend interstellar mission life On April 17, engineers at NASA’s JPL sent commands to deactivate the Low-energy Charged Particles (LECP) experiment aboard Voyager 1 to preserve power. The 48-year-old spacecraft is now about 24 billion kilometers from Earth and is continuing its interstellar journey by turning off additional systems as batteries fade.
