A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.
Material falling into a black hole casts X-rays out into space – and now, for the first time, ESA's XMM-Newton X-ray observatory has used the reverberating echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself.
Observations from ESA's Rosetta spacecraft are shedding light on the mysterious make-up of Comet 67P/Churyumov-Gerasimenko, revealing a mix of compounds thought to be essential precursors to life – including salts of ammonium and a particular type of hydrocarbons.
ESA's XMM-Newton has discovered that gas lurking within the Milky Way's halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.
Astronomers using the combined powers of ESA's Rosetta mission and the ground-based Atacama Large Millimeter/submillimeter Array (ALMA) have traced the journey of phosphorus – one of life's building blocks – from star-forming regions to comets.
ESA's new Sun explorer will be launched from Cape Canaveral on 8 February. Media are invited to Europe's mission control centre in Darmstadt, Germany, to follow the launch and moment of signal acquisition.

The assembly of the flight model of ESA's JUICE spacecraft began in September, with the delivery of the spacecraft's primary structure, followed by integration of the propulsion system that will enable the mission to reach and study Jupiter and its moons.
