Video: 00:00:57 More than 5000 exoplanets have been discovered to date, but what do they look like? ESA’s dedicated exoplanet missions Cheops, Plato and Ariel are on a quest to find out. Cheops will focus its search on mini-Neptunes, planets with sizes between Earth and Neptune, on short orbits around their stars. Cheops will find out how large these planets are, and may detect whether the planets have clouds. Plato will look at all kinds of exoplanets and determine their sizes and ages. Plato’s instruments are so sensitive it may discover the first Earth-like planet on an Earth-like orbit. Finally, Ariel will look at the atmospheres of exoplanets using the techni…

A Wolf-Rayet star is a rare prelude to the famous final act of a massive star: the supernova. As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. View the full article

Video: 00:13:54 A year has passed since the launch of the ESA’s Rosalind Franklin rover mission was put on hold, but the work has not stopped for the ExoMars teams in Europe. In this programme, the ESA Web TV crew travel back to Turin, Italy to talk to the teams and watch as new tests are being conducted with the rover’s Earth twin Amalia while the real rover remains carefully stored in an ultra-clean room. The 15-minute special programme gives an update on what happened since the mission was cancelled in 2022 because of the Russian invasion of Ukraine, the plan ahead, the new challenges, the latest deep drilling test and the stringent planetary protection measure…

Europe’s Galileo is the world’s most precise satellite navigation system, providing metre-level accuracy and very precise timing to its four billion users. An essential ingredient to ensure this stays the case are the atomic clocks aboard each satellite, delivering pinpoint timekeeping that is maintained to a few billionths of a second. These clocks are called atomic because their ‘ticks’ come from ultra-rapid, ultra-stable oscillation of atoms between different energy states. Sustaining this performance demands, in turn, even more accurate clocks down on the ground to keep the satellites synchronised and ensure stability of time and positioning for users. View the ful…

Today Galileo is the world’s most precise satellite navigation system, delivering metre-level accuracy, and if you are a modern smartphone owner then you – like nearly four billion others around the world – are among its users. This week we are celebrating that almost exactly a decade ago, on 12 March 2013, Europe for the first time ever was able to determine a position on the ground using only its own independent navigation system, Galileo.
