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.
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.
ESA's XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster – a never-before-seen behaviour that may be driven by turbulent merger events.
New observations from the NASA/ESA Hubble Space Telescope have investigated the nature of the gamma-ray burst GRB 190114C.
