+ TRACING THE UNIVERSE: X-RAY SURVEY SUPPORTS STANDARD COSMOLOGICAL MODEL
Scanning the sky for X-ray sources, ESA's XMM-Newton X-ray observatory has been busy with the XXL Survey, its largest observational programme to date. The second batch of data from the survey has just been released, including information on 365 galaxy clusters, which trace the large-scale structure of the Universe and its evolution through time, and on 26 000 active galactic nuclei (AGN).

+ HUBBLE FINDS COMPELLING EVIDENCE FOR A MOON OUTSIDE THE SOLAR SYSTEM [HEIC1817]
Using the NASA/ESA Hubble Space Telescope and older data from the Kepler Space Telescope two astronomers have found the first compelling evidence for a moon outside our own Solar System. The data indicate an exomoon the size of Neptune, in a stellar system 8000 light-years from Earth. The new results are presented in the journal Science Advances.

+ A BRIEF INTRODUCTION TO EXOPLANETS
The first discoveries of exoplanets in the 1990s completely changed our perspective of the Solar System and opened up new areas of research that continues today. With the steady rise in the number and type of known exoplanets, there is a lot to learn as we move from an era of detecting planets around other stars to one of characterising them.
