The Chinese Academy of Sciences (CAS) spacecraft Einstein Probe is ready to launch in January 2024. Equipped with a new generation of X-ray instruments with high sensitivity and a very wide view, this mission will survey the sky and hunt for powerful blasts of X-ray light coming from mysterious celestial objects such as neutron stars and black holes. Einstein Probe is a collaboration led by CAS with the European Space Agency (ESA) and the Max Planck Institute for Extraterrestrial Physics (MPE), Germany. View the full article

Image: Ten years ago, on 19 December 2013, ESA’s billion star-mapping satellite Gaia launched. Since then, Gaia has been scanning the sky and gathering an enormous amount of data on the positions and motions of 1.8 billion stars, enabling numerous discoveries about the history of our galaxy. Gaia’s catalogue is ever-growing containing data on stars and other cosmic objects such as asteroids in our Solar System, exoplanets, binary stars, and other galaxies. The Gaia collaboration, consisting of about 450 people in 25 countries, prepares the data for scientific use. This has resulted in publications of over 10 000 scientific papers and 128 PhD theses.

The NASA/ESA/CSA James Webb Space Telescope recently trained its sights on weird and enigmatic Uranus, an ice giant that orbits on its side. What Webb found is a dynamic world with rings, moons, storms, and other atmospheric features – including a seasonal polar cap. The image expands upon a two-colour version released earlier this year, adding additional wavelength coverage for a more detailed look. View the full article

Video: 00:08:22 2023’s highlight was the highly anticipated launch of Juice, Europe’s Jupiter Icy Moon Explorer. The Juice spacecraft was placed on course to Jupiter on the second-to-last Ariane 5 launch vehicle in April. After an eight-year journey, Juice will begin observing the giant gas planet and its three large ocean-bearing moons – Ganymede, Calisto and Europa. The Euclid space telescope was launched in July with the aim of unravelling the enigmas of ‘dark matter’ and ‘dark energy’. Euclid’s first images were released in November, revealing razor-sharp astronomical images with detail never before seen by a telescope across such a large patch of the sky. Aft…

Discovery helps answer the question: How small can you go when forming stars? Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. In a quest to find the smallest brown dwarf, astronomers using the NASA/ESA/CSA James Webb Space Telescope have found the new record-holder: an object weighing just three to four times the mass of Jupiter.

Video: 00:01:25 Trailer of the ExoMars Rosalind Franklin mission. In 2028, ESA will launch its most ambitious exploration mission to search for past and present signs of life on Mars. Enjoy the ExoMars Rosalind Franklin mission in minute detail – everything down to the colour and size of the wires, sticky tape and scratches. The spacecraft, the rover and martian landscapes are as true to reality as possible for a simulation. The visuals show the spacecraft structural engineering with a faithful robotic appearance. The martian landscape has been simulated with meticulous realism. The story begins with the rover exploring the surface of the Red Planet. There is scie…
