Gaia's first data release was not designed to be a full database with which major scientific discoveries could be made. Instead it was foreseen much more as a set of test data that astronomers could practice on and get ready for the second release from ESA's billion-star surveyor – the one that would feature a billion parallaxes and proper...

This colourful cloud of glowing interstellar gas is just a tiny part of the Lagoon Nebula, a vast stellar nursery. This nebula is a region full of intense activity, with fierce winds from hot stars, swirling chimneys of gas, and energetic star formation all embedded within a hazy labyrinth of gas and dust.

Media representatives are invited to a briefing on the second data release of ESA's Gaia mission, an astrometry mission to map more than one billion stars in our Galaxy, the Milky Way. The media briefing is being organised by ESA at the ILA Berlin Air and Space Show in Germany, on Wednesday 25 April 2018.

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.
