Ice cloud heralds fall at Titan's south pole

An ice cloud taking shape over Titan's south pole is the latest sign that the change of seasons is setting off a cascade of radical changes in the atmosphere of Saturn's largest moon. Made from an unknown ice, this type of cloud has long hung over Titan's north pole, where it is now fading, according to observations made by the Composite Infrared Spectrometer on NASA's Cassini spacecraft.

An improved mathematical method for simulating the evolution of the solar system

In order to improve a simulation designed to study the evolution of the solar system through time, numerical mathematical methods have been developed at the Computing Faculty of the University of the Basque Country (UPV/EHU). Specifically, the methods proposed enable the simulation calculations to be done faster and more accurately.

Hubble breaks record in search for farthest supernova

NASA's Hubble Space Telescope has found the farthest supernova so far of the type used to measure cosmic distances. Supernova UDS10Wil, nicknamed SN Wilson after American President Woodrow Wilson, exploded more than 10 billion years ago.

Listening to the Big Bang - in high fidelity

A decade ago, spurred by a question for a fifth-grade science project, physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago. Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background, Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound.
