Jupiter’s moon Ganymede is the only satellite in the Solar System known to have an intrinsic magnetic field. Interactions between this field and the magnetosphere of Jupiter are expected to funnel most of the associated impinging charged particles, which alter surface chemistry across the Jupiter system, to Ganymede’s polar regions. Using observations obtained with the NASA/ESA/CSA James Webb Space Telescope, astronomers have now detected hydrogen...

ESA’s Euclid spacecraft will orbit the second Lagrange point (L2), 1.5 million km from Earth in the opposite direction to the Sun. L2 is an equilibrium point of the Sun-Earth system that follows Earth around the Sun. In its orbit at L2, Euclid’s sunshield can always block the light from the Sun, Earth and Moon while pointing its telescope towards deep space, ensuring a high level of stability for its instruments. At L2, Euclid joins ESA’s Gaia mission and the ESA/NASA/CSA James Webb Space Telescope, which are also orbiting around this equilibrium point, each following well separated trajectories.
