INTEGRAL reveals new facets of the Vela pulsar wind nebula
Astronomers studying the Vela pulsar wind nebula with ESA's INTEGRAL observatory have successfully resolved its morphology in the hard X-ray band, for the first time. This pulsar-powered nebula is the most extended individual source yet observed at these energies. The study exploited a special imaging technique to reveal a new component of the source that likely consists of highly energetic electrons that have escaped from the core of the nebula in the last few thousand years.

Cassini's radar observes Titan's tropical dune fields
Sand dunes are common on Earth, Mars, Venus and - unexpectedly - on Saturn's giant moon, Titan. Now detailed analysis of radar observations gathered during the Cassini spacecraft's flybys of cloud-shrouded Titan is enabling scientists to understand the distribution, shape and dimension of its exotic dunes.
