For the first time, astronomers have detected synchronised pulses of optical and X-ray radiation from a mysterious pulsar some 4500 light years away. The observations indicate that a new physical mechanism might be needed to explain the behaviour of fast-spinning sources like this one, known as transitional millisecond pulsars.

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that chronological age alone does not tell the complete story when it comes to the evolution of star clusters.

Rather than leaving home young, as expected, stellar 'siblings' prefer to stick together in long-lasting, string-like groups, finds a new study of data from ESA's Gaia spacecraft.

The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth's magnetosphere, to pave the way for this pioneering venture.
