New techniques developed by the ISOLTRAP collaboration are allowing investigations of a possible birthplace of the heavy elements.
Read article 'Pulsar exhibits puzzling switches in state'
Astronomers have detected simultaneous X-ray and radio-mode switches in co-ordinated observations of a pulsar. Pulsed X-ray emission is only present in states of weak radio emission. This indicates a ...

Researchers using the European X-ray astronomy satellite XMM-Newton have discovered a new source of low-energy cosmic rays in the vicinity of the Arches cluster, near the centre of the Milky Way.
Read article 'Titanium illuminates the 1987 supernova'
The INTEGRAL gamma-ray satellite has detected the radioactive decay of an isotope of titanium, 44Ti, in the remnant of the nearby supernova SN 1987A. This observation confirms that 44Ti powers th...
