An international research collaboration, including scientists from the University of Geneva (UNIGE) and the National Centre of Competence in Research PlanetS, has identified a new super-Earth circling a star cooler than the Sun. The planet, named TOI-512 b, was confirmed through precision measurements by ESPRESSO, a spectrograph developed under the leadership of UNIGE. With a density nearly iden

The United Nations on Tuesday urged countries to boost protections amid a marked increase in efforts to interfere with satellite navigation systems like GPS that are critical for aviation and maritime safety. The UN's International Telecommunication Union, its International Civil Aviation Organization (ICAO) and the International Maritime Organization jointly voiced "grave concern" at growin

Two spacecraft flying as one – that is the goal of European Space Agency’s Proba-3 mission. Earlier this week, the eclipse-maker moved a step closer to achieving that goal, as both spacecraft aligned with the Sun, maintaining their relative position for several hours without any control from the ground.

From 25 July 2014 to 15 January 2025, the Gaia space observatory performed high-precision measurements of nearly two billion stars from its Lissajous orbit around the L2 Lagrange point, 1.5 million km from Earth. 

After 10.5 years of groundbreaking observations, Gaia’s cold gas supply for attitude control has been depleted. On 27 March 2025, Gaia will leave its Lissajous orbit and transition into a stable heliocentric orbit. Soon after, the spacecraft will be passivated, with its instruments and transmitters switched off. 

While Gaia will no longer collect new data, its scientific mission is far from over! The team continues

The European Space Agency (ESA) has powered down its Gaia spacecraft after more than a decade spent gathering data that are now being used to unravel the secrets of our home galaxy.

On 27 March 2025, Gaia’s control team at ESA’s European Space Operations Centre carefully switched off the spacecraft’s subsystems and sent it into a ‘retirement orbit’ around the Sun.

Though the spacecraft’s operations are now over, the scientific exploitation of Gaia’s data has just begun.

The high-performance computing (HPC) environment will be available for scientific research and technological development activities, supporting all ESA programmes as well as the researchers and small- and medium-enterprises from Member States.
