View from the Operations Manager desk across the control room at ESOC in Darmstadt, Germany.. The European Space Agency (ESA) operates a number of missions, both operational and scientific, including collaborations with other national space agencies such as the Japan Aerospace Exploration Agency (JAXA), the National Centre for Space Studies (CNES), the Italian Space Agency (ASI), the German ...
Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until Spring 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [6] [7] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.

In 2018, the Gaia project of the European Space Agency, designed primarily to investigate the origin, evolution and structure of the Milky Way, delivered the largest and most precise census of positions, velocities and other stellar properties of more than a billion stars, which showed that Sgr dSph had caused perturbations in a set of stars ...
Astronomers using the Gaia space telescope have located two ancient streams of stars that helped the Milky Way galaxy grow and evolve more than 12 billion years ago.
The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. This one is 100 light-years away in the constellation Coma Berenices. A light-year is 5.8 ...
The photos were revealed by the European Space Agency, four months after the telescope launched from Cape Canaveral. ... galaxy that is a ringer for our own Milky Way. Although the Hubble Space ...
The European Space Agency (ESA) was established in May 1975 as the merger of the European Space Research Organisation (ESRO) and the European Launcher Development Organisation. [ 29 ] [ 30 ] [ 31 ] In 1970, the governing Launch Programme Advisory Committee (LPAC) of ESRO made a decision not to execute astronomy or planetary missions, which were ...
[10] As the European Space Agency states, Oort "sh[ook] the scientific world by demonstrating that the Milky Way rotates like a giant 'Catherine Wheel'." He showed that all the stars in the galaxy were "travelling independently through space, with those nearer the center rotating much faster than those further away." [5]
