Josef Aschbacher, Director General of the European Space Agency, briefed journalists on the main milestones for 2026, such as the launch of Smile, a mission that will give humankind its first complete look at how Earth reacts to streams of particles and bursts of radiation from the Sun. Later in 2026 should also see the arrival of BepiColombo at Mercury after its eight-year trip, where it will gather data to answer many perplexing questions about the least-explored planet of the inner Solar System. Many more exciting missions are expected, with ESA astronaut Sophie Adenot launching for the International Space Station, and various Earth Observation and Navigation launches from Europe’s Spaceport in French Guiana.

As a new year begins, let’s take a look at what’s ahead for the European Space Agency in 2026. From Earth to the farthest reaches of the Solar System, 2026 marks a year of firsts that continue to shape the future of space.

The European Space Agency (ESA) and Playmobil are expanding their successful partnership with a brand-new collection of space-themed toys, bringing a distinctly European vision of Mars exploration into the hands of young explorers.

Often called Earth’s green lungs, tropical forests pull down massive amounts of carbon dioxide from the atmosphere, release oxygen and help regulate the global climate. While the threat of large-scale deforestation is well known, new findings reveal a surprising culprit – the clearance of small areas of forest accounts for more than half of net carbon losses across the Tropics.

So let’s say you set up an experiment to measure a quantum property of subatomic particles. Like, I don’t know, spin.

All of physics rests on causal determinism. It’s like…how we do physics. It IS physics.

New research shows that Jupiter's moon Europa, one of the prime targets in the search for life, may not have the conditions required after all. The research shows that the moon lacks the type of active seafloor faulting needed to create habitability. Deep sea vents created by the faulting introduce nutrients into the water that organisms use to harness energy, and without those nutrients, the moon's subsurface ocean is likely dead.

Drugs like Ozempic have transformed how we treat obesity, but a review of almost 40 studies shows it doesn't take long for people to regain weight if they come off them
