Before its demise, the Dawn spacecraft performed a series of low passes over the bright spots of dwarf planet Ceres. These high-resolution data highlight the nature of Ceres as an active ocean world with unique characteristics.
The practice of peer review has only become commonplace fairly recently, and as such is continually undergoing revision. The latest progress has focused on reducing the load on those performing this community service and also reducing bias to ensure a fairer system for all.
The Emirates will shortly join the ranks of space-faring nations by sending an orbiter to Mars, aiming to make novel observations and inspire the country, write the mission leadership team.
As the Tianwen-1 spacecraft is scheduled for launch in late July or early August, the mission chief scientist and his team provide an overview focusing on the scientific objectives and instrumentation of China’s first Mars mission.
The historic launch of the first several hundred out of 12,000 planned Starlink satellites heralds the arrival of the era of ultra-large satellite constellations. If it will bring new opportunities or insurmountable challenges to astronomy will probably depend on whether you are conducting your observations in space or from the surface of the Earth.
On 3 May 2020 the Greek and extended international astronomy community lost Professor Emeritus John Hugh Seiradakis, a highly impactful, wide-reaching researcher and educator, and mentor to generations of students.
The space and planetary science community lost a great leader, Professor Weixing Wan, on 20 May 2020, aged 62. He was a world-leading space scientist and a pioneer in China’s planetary science programme.
On the anniversary of ROSAT’s launch, we reflect on the relevance and promise of X-ray observations in all fields of astronomy. Properly laying out a plan for the future of the field will allow it to continue flourishing.
No confirmed counterparts during LIGO and Virgo’s third observing run bring more questions than answers to the active multi-messenger community, which is adapting collaboratively and technically as expectations evolve and more data are taken.
eROSITA, a new X-ray telescope currently performing an all-sky survey of unprecedented depth, aims to provide insights into dark energy, dark matter, black holes and perhaps new phenomena that have so far been invisible.
