Scientists seek to understand the elusive properties of stellar and galactic cosmic rays before searching for life on exoplanets.Read More »Planetary Sciences
Sixty-six million years ago, an asteroid reset most of life on Earth. But without this catastrophic event, the composition of neotropical rain forests wouldn’t be the same.Read More »
On early Earth, rock created by lightning strikes to the ground likely held a form of phosphorus necessary for prebiotic chemistry.Read More »Planetary Sciences
Even the strong heating from short-lived aluminium-26 (26Al) would not be able to homogenize the interior of a Mars‐sized planetary embryo.Read More »Planetary Sciences
Large-scale lava experiments are helping scientists imagine how metallic lava would flow across and shape a landscape, either on Earth or on a distant asteroid.Read More »Planetary Sciences
While some Earth-like worlds can generate significant O2 only by biology, “waterworlds” and “desert worlds” can build up O2 even without life because of chemical changes from atmosphere loss to space.Read More »Planetary Sciences
Algún día, un catálogo de fragmentos moleculares podría ayudar a científicos a identificar vida extraterrestre en las lunas heladas de nuestro sistema solar.Read More »Planetary Sciences
Climate change appears to be directly and indirectly affecting the view from at least one observatory while threatening the existence of others.Read More »Planetary Sciences
An imaging campaign after the 2018 planet-encircling dust storm on Mars revealed a significant increase in detections of enigmatic recurring slope lineae and new insights into how they might form.Read More »
