Mars Still Has Liquid Rock Near its Core
Why doesn’t Mars have a magnetic field? If it did, the planet would be protected from cosmic radiation and charged particles emitted by our Sun. With a magnetic field, perhaps the Red Planet wouldn’t be the dry, barren world it is today.
An Exo-Neptune Beat the Odds and Kept its Atmosphere
As planet-hunting scientists find more and more planets, they’ve encountered some puzzles. One of them concerns the lack of Neptune-size worlds orbiting close to their stars. Astronomers think that these planets aren’t massive enough to retain their atmospheres in the face of their stars’ powerful radiation, which strips it away.
Here's how NASA's Roman Space Telescope will hunt for lonely black holes and distant exoplanets
NASA has revealed how the Nancy Grace Roman Space Telescope will grant astronomers the deepest view into the heart of the Milky Way ever as they hunt for planets, stars, black holes and more.
Satellite data reveals ancient landscape preserved beneath East Antarctic ice sheet
The 'ghost' of ancient river-carved landscape discovered has been preserved beneath the East Antarctic ice sheet since the continent froze over 34 million years ago.
Rocket Lab aims to return to flight this year after September launch failure
Rocket Lab is still investigating what caused its Electron vehicle to fail on Sept. 19, but the company is confident it will be back on the launch pad in 2023.
Artemis 2 Orion spacecraft comes together ahead of 2024 moon mission (photos)
Sections of the Orion spacecraft tasked with flying four astronauts around the moon during the Artemis 2 mission have been joined together. The mission is set for no earlier than late 2024.
Hot summer for Europe's reusable rocket engine
An ongoing project to develop a low-cost, reusable engine for European rockets made considerable progress over the summer and autumn, with a series of tests that achieved full ignition and, ultimately, a 30-second burn with re-ignition of an early prototype of the Prometheus engine.
Declassified spy satellite images reveal 400 Roman Empire forts in the Middle East
The Ancient Romans constructed hundreds of forts near their eastern borders in modern-day Syria and Iraq. Declassified spy satellite imagery spotted the forts and may shed light on the battlements' purpose.
Nailing down exoplanet orbits could be key to finding ET. Here's why
A better understanding of exoplanet orbits is helping SETI astronomers reduce their computational costs and conduct their search for intelligent aliens faster.
Six trends to watch in commercial Earth observation
With a multitude of opportunities for start-ups, established companies and investors, commercial Earth observation is a vibrant sector with fast-moving innovations in technology, datasets and downstream applications. ESA is a key driving force for the development of European Earth observation and provides impetus through its many programmes and initiatives.
Mission Spatiale arrives at the Cité des sciences et de l’industrie in Paris
The permanent exhibition Mission Spatiale just opened its doors at the Cité des sciences et de l’industrie in Paris. Produced in collaboration with the European Space Agency (ESA), this immersive exhibition is dedicated to space exploration and invites visitors to embark on an interactive journey structured into five steps: Explore, Travel, Transit, Stay and Questions.
Introducing roster recruitment at ESA
We are pleased to announce the introduction of roster recruitment at ESA as a new way to launch your career with us. If you work in a field for which ESA consistently recruits in high numbers, such as system engineering, corporate controlling and product assurance, placement on a roster will open up your access to job opportunities with us. The first ESA roster recruitment position has just been published, so here is a short explainer to bring you up to speed on this new system.
China launches new 3-astronaut crew to Tiangong space station
A Long March 2F rocket lifted off from the Jiuquan Satellite Launch Center in the Gobi Desert today (Oct. 25), carrying the Shenzhou 17 spacecraft and its crew into orbit.
Cosmonauts on ISS spacewalk encounter toxic coolant 'blob' while inspecting leaky radiator
Russian cosmonauts Oleg Kononenko and Nikolai Chub got an up-close view of a coolant leak flowing from an external radiator while conducting a spacewalk outside of the International Space Station.
What’s Inside the Carina Pillars? Massive Protostars and Newly-Forming Planets!
Star-forming nebulae are busy places. Unfortunately, clouds of gas and dust usually hide the action. To cut through the dust in one such region, a team of astronomers used the Atacama Large Millimeter Array (ALMA). They peered inside the Pillars of the Carina Nebula and studied molecular outflows (or jets) emanating from objects in this famous star-birth nursery.
Io has 266 Active Volcanic Hotspots Linked by a Global Magma Ocean
Jupiter’s Io stands apart from the Solar System’s other moons, with its numerous volcanoes and its surface dominated by lava flows. Io’s surface volcanism was confirmed in 1979 when the Voyager spacecraft imaged it, but its volcanic nature isn’t duplicated anywhere else in our system. Tidal heating is behind the moon’s eruptive nature, driven by Jupiter’s powerful gravity, and by resonance with other moons. But is there a magma ocean inside Io?
Climate change has pushed Earth into 'uncharted territory': report
A new climate report finds humanity is pushing Earth's systems into "dangerous instability."
After DART Smashed Into Dimorphous, What Happened to the Larger Asteroid Didymos?
NASA’s DART mission (Double Asteroid Redirection Test) slammed into asteroid Dimorphos in September 2022, changing its orbital period. Ground and space-based telescopes turned to watch the event unfold, not only to study what happened to the asteroid, but also to help inform planetary defense efforts that might one day be needed to mitigate potential collisions with our planet.
Russian spacewalkers to inspect leaking radiator

Two Russian cosmonauts ventured outside the International Space Station Wednesday to look for the source of a leak at or near a newly installed radiator on the Nauka lab module and to isolate it from coolant lines.
A Windy and Wonderful Icelandic Aurora Adventure
Sky & Telescope’s recent tour to Iceland explored all the island’s sights — and kept S&T’s record at a solid nine for nine for seeing auroras!
