For years, astronomers believed the Milky Way and Andromeda were on a direct collision course in about 4.5 billion years. But new research using data from our Gaia mission and Hubble Space Telescope suggests the story isn’t so simple.
After running 100 000 simulations with the most precise data available, scientists now say there’s only a 50% chance the two galaxies will collide in the next 10 billion years.
The Large Magellanic Cloud, one of our satellite galaxies, could be tugging the Milky Way just enough to steer it away from Andromeda. Instead of crashing, the two galaxies might simply orbit each other in a slow cosmic dance.
So the fate of the Milky Way remains uncertain. And with the Sun expected to make Earth uninhabitable in about a billion years, a galaxy collision is low on our list of concerns.

Meet Flyeye — the telescope that sees space like a fly! 🪰
With its very first glimpse of the sky, Flyeye is ready to begin scanning for asteroids that might one day come a little too close to Earth.
Inspired by the compound eye of a fly, it can spot a huge chunk of sky in one go — more than 200 times the area of the full Moon. And it’s designed to do it all automatically, night after night.
It hasn’t found any space rocks yet, but it’s only just opened its eye. This is the first step towards a future network of fly-eyed telescopes keeping watch over our planet.
Each year on 22 April, people across the planet join forces to raise awareness about the unequivocal effects of climate change and the importance of protecting our planet for future generations. We celebrate Earth Day every day at ESA. 💙

Phobos sits very close to Mars by Solar System standards, orbiting just 6000 km from Mars’s surface. For context, our own moon lies about 385 000 km away from Earth’s surface.
Oxia Planum contains one of the largest exposures of rocks on Mars that are around 3.9 billion years old and clay-rich, indicating that water once played a role here. The site sits in a wide catchment area of valley systems with the exposed rocks exhibiting different compositions, indicating a variety of deposition and wetting environments.
A European rover, Rosalind Franklin, is part of the ExoMars programme that will explore the surface of Mars. The rover will be the first mission to combine the capability to move across the surface and to study Mars at depth.

ESA’s latest astrophysics mission, Euclid, lifted off on a Space X Falcon 9 from Cape Canaveral in Florida, USA, at 17:12 CEST on 1 July 2023.
Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometres from Earth, in the opposite direction from the Sun.
The telescope will survey one third of the sky with unprecedented accuracy and sensitivity. By observing billions of galaxies out to 10 billion light-years, it will create the most extensive 3D-map of the Universe, with the third dimension representing time.
ESA’s Euclid mission is designed to explore the composition and evolution of the dark Universe. Euclid will chart how the Universe has expanded and how large-scale structure is distributed across space and time, revealing more about the role of gravity and the nature of dark energy and dark matter.
Four weeks after launch, Euclid will enter its orbit around L2. Once in orbit, mission controllers will start the activities to verify all functions of the spacecraft, check out the telescope and finally turn the instruments on. Following this, scientists and engineers will be engaged in an intense two-month phase of testing and calibrating Euclid’s scientific instruments, and preparing for routine observations. The telescope begins its early phase of the survey of the Universe three months after launch.
We are Europe’s gateway to space. Our mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world. Check out https://www.esa.int/ to get up to speed on everything space related.

Where did our Moon come from? Over the years, there have been several theories, but most scientists think it’s likely that a Mars-sized object smashed into Earth, creating what we now see in the sky.

Our journey back to the Moon and onto Mars starts at home, and NASA’s Veterans are a big part of accomplishing that mission. Veterans currently make up 12% of the NASA workforce. Many of the most iconic figures at the agency—our astronauts—have a strong veteran tie. In fact, all NASA astronauts were military pilots until 1965. Of the 385 total NASA Astronauts, 223 are Veterans! Veterans continue to have a sweeping impact on NASA, in every corner of our workforce. Thanks to all the men and women who have served in our armed forces. Have a safe and happy Veterans Day.

Once the preparatory work has been completed, and the satellite developed and manufactured, the next step is launch and operations with a view to ensuring that it fulfils its original mission objectives. The post-launch phase can span many years, often as long or longer than the developmental phase. Some ESA scientific satellites even continue to operate beyond their original planned lifespan.
Join ESA experts working in launchers, operations, mission management and scientific data processing to find out what happens in the final phases of the mission when all the planning and development comes to fruition.

R&D plays a key role as part of ESA’s mission to share the development of Europe’s space capability and to keep European industry at the leading edge of technology development. Not only are new and innovative technologies constantly being developed and tested to pave the way for future satellite projects, but ESA is also facilitating their application to scientific and commercial products and services. And well before an individual satellite project can be started, ESA and its experts are hard at work preparing the way through feasibility studies and assessments.
Join ESA experts working in the Concurrent Design Facility, Phi-Lab and the ARTES Programme to hear about their contributions to the overall ESA mission.

Have you ever wondered what it was like to work in a satellite development project at the European Space Agency? Learn from the experts working in the Ariel satellite project team.
Fiona Walsh from ESA Human Resources moderates a panel with Jean-Christophe Salvignol, ESA’s Ariel Project Manager and a couple of his managers. They explain the incredible team effort required to bring this complex project from early inception, manufacturing of the satellite, accommodating its payloads and ensuring a successful launch to pave the way for exciting scientific discoveries. Ariel is one ESA’s science missions that will be launched in 2029 and will discover the composition of exoplanets by examining their atmospheres.
They explain how the project team is structured and a bit about the international collaboration involved. They also touch on the importance of building the right team and creating a great team spirit.

Computing power doubles every two years, an observation known as Moore’s Law. Prof Maarten Steinbuch, a high-tech systems scientist, entrepreneur and communicator, from Eindhoven University of Technology, discussed how this exponential rate of change enables accelerating developments in sensor technology, AI computing and automotive machines, to make products in modern factories that will soon be smart and self-learning. Cars will become like an iPad on wheels. The questions are, when will they be better than humans? Will humans still be necessary? And what does the future of schools and universities look like?
