Proving special relativity: episode 3

One of the most nonintuitive consequences of Einstein’s theory of special relativity is the idea that different people will experience time at different rates. This has no analog in classical theory, and yet it is easy to observe at laboratories such as Fermilab and CERN.

Saturn’s hexagon: an amazing phenomenon

Saturn’s hexagon: an amazing phenomenon

The puzzling hexagon-shaped weather pattern around Saturn's north pole was first found in images from Voyager 2 (left). Cassini has obtained higher-resolution pictures of the hexagon (such as the one on the right, taken in 2009) - which tell scientists the hexagon is a remarkably stable wave in one of the jet streams that remains 30 years later. (Credit : NASA-JPL)

Researchers at the Planetary Sciences Group of the UPV/EHU-University of the Basque Country reveal some of the secrets of Saturn’s mysterious hexagonal wave, including its rotation period, which could be that of the planet itself

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades – that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a…
