¿Por qué los humanos estamos dispuestos a pasar por alto el riesgo que supone para la vida marciana la exploración y colonización del planeta rojo?
- Professor of Astronomy, Vanderbilt University
NASA’s InSight Mars lander touches down Nov. 26, part of a careful robotic approach to exploring the red planet. But human exploration of Mars will inevitably introduce Earth life. Are you OK with that?
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
With increasing knowledge and familiarity, we’ll no longer be able to identify meaningful criteria to keep these good planets down.
The wise men were likely accomplished Greek astrologers, watching the stars for signs of a king’s birth. Technical terms used in the Bible’s description point to a real astronomical event.
Astronomers have found thousands of exoplanets and the hunt is on for life beyond Earth. Once biological neighbors are identified, our planet’s philosophies and religions will need to adapt.
