While charting the positions of more than a billion stars, ESA's Gaia mission provides all-important information even about the dark patches of the sky where fewer stars are observed. These images, based on Gaia's first data release, are an appetizer to the astronomical riches that will be unleashed with the mission's second release on 25 April.

Astronomers using the NASA/ESA Hubble Space Telescope have found the most distant star ever discovered. The hot blue star existed only 4.4 billion years after the Big Bang. This discovery provides new insight into the formation and evolution of stars in the early Universe, the constituents of galaxy clusters and also on the nature of dark matter.

In 2014, ESA's XMM-Newton spotted X-rays emanating from the massive star Rho Ophiuchi A and, last year, found these to ebb and flow periodically in the form of intense flares – both unexpected results. The team has now used ESO's Very Large Telescope to find that the star boasts a strong magnetic field, confirming its status as a cosmic lighthouse.
