A variation on the theory of quantum gravity – the unification of quantum mechanics and Einstein’s general relativity – could help solve one of the biggest puzzles in cosmology, new research suggests. Scientists have known for almost a century that the universe is expanding. But in recent decades, physicists have discovered that several types of … Read more
Landmarks on Europa’s surface suggest that the ice crust is at the mercy of the waters below. Most importantly, a recent visit from Juno reveals what could be plume activity, which could allow future missions to sample the internal ocean without having to land. It’s been almost two years since Juno made its closest approach … Read more
Resume: A new study finds that Eurasian jays exhibit episodic memory, a type of memory previously thought to be unique to humans. The birds were able to remember incidental details of past events, such as the visual features of cups used in an experiment to hide food. This finding suggests that episodic memory may not … Read more

NASA is preparing to launch its latest climate science mission, the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE), which aims to capture brand new data on how heat is lost from Earth’s polar regions to space . PREFIRE consists of a pair of cubesats launched separately into near-polar orbits. The first, “Ready, Aim, PREFIRE,” … Read more
Space enthusiasts will know: it’s easy to get caught up in a wealth of fascinating developments, from missions to the lunar surface to new discoveries in exoplanet science. But what really excites me as an astronomer right now is a largely overlooked development here on Earth that could have profound implications for how we explore … Read more
