Astronomers recently used a trove of archived images taken by the NASA/ESA Hubble Space Telescope to visually snag a largely unseen population of smaller asteroids in their tracks. The treasure hunt required pursuing 37 000 Hubble images spanning 19 years. The payoff was finding 1701 asteroid trails, with 1031 of those asteroids uncatalogued. About 400 of these uncatalogued asteroids are about below a km in size.
As humans exert greater pressure on natural processes, understanding the intricate workings of our Earth system is increasingly vital for effective action on mitigation and adaption strategies. ESA’s Earth Explorer missions yield a wealth of astonishing findings, serving as the bedrock of scientific research in this field. Now, four new concepts have been selected to undergo assessment study, one of which is destined to be the twelfth in this family of world-leading satellite missions.
After being packed up in Germany, a long voyage to the US and then a month in storage, ESA’s EarthCARE satellite has been carefully lifted out of its transport container so that the team at the launch site can start getting it ready for its big day in May.
Wading through the wealth of data from ESA’s Gaia mission, scientists have uncovered a ‘sleeping giant’. A large black hole, with a mass of nearly 33 times the mass of the Sun, was hiding in the constellation Aquila, less than 2000 light-years from Earth. This is the first time a black hole of stellar origin this big has been spotted within the Milky Way. So far, black holes of this type have only been observed in very distant galaxies. The discovery challenges our understanding of how massive stars develop and evolve.

Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth.
One year of basic training will soon bear fruit for ESA’s astronaut candidates Sophie Adenot, Pablo Álvarez Fernández, Rosemary Coogan, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg.

As they reach the end of one year of rigorous basic astronaut training, ESA astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg will receive astronaut certification at ESA’s European Astronaut Centre on 22 April 2024.
One year since the launch of ESA’s Jupiter Icy Moons Explorer (Juice), we catch up with core team members Claire Vallat, Giuseppe Sarri, Olivier Witasse and Ignacio Tanco.

On the last day of his Huginn mission, ESA astronaut Andreas Mogensen takes us on a tour of the place he called home for 6 months: the International Space Station. From the beautiful views of Cupola to the kitchen in Node 1 filled with food and friends and all the way to the science of Columbus, the Space Station is the work and living place for astronauts as they help push science forward.
