First Metal Object 3D-Printed in Space Recovered on Earth
The first metal thingamajig ever 3D printed in space has landed on Earth, where European Space Agency (ESA) scientists are now studying it.
In a press release, the ESA announced that the object — a round metal demonstration part, produced on the International Space Station, that features a variety of stubby cylindrical objects — is now safely in the hands of agency scientists in the Netherlands.
At the ESA's European Space Research and Technology Center (ESTEC), scientists will soon conduct quality analysis experiments to see what differences show up in objects manufactured in zero-gravity environments. A second, similarly 3D-printed object will be brought back to Earth and handed over to the Technical University of Denmark.
Just over a year ago, ESA astronaut Andreas Mogensen successfully installed the Airbus-built metal 3D printer in the Space Station's Columbus module — a feat unto itself, given that setting up complicated machinery like that is hard enough on Earth and all the more so without gravity.
Soon after, the printer proved its prowess when it printed a curly "S" shape on a flat piece of metal, followed by two full samples including the one now in the hands of ESA scientists at ESTEC.
Though this feat will inevitably help pave the way for future off-world manufacturing endeavors, this wasn't the first time an object had been 3D printed in orbit.
That distinction occurred more than a decade ago, when NASA astronaut Butch Wilmore — the same one who's slated to come back down to Earth in a few weeks after being stuck on the ISS for 10 months longer than expected — installed and test-calibrated the first-ever in-orbit 3D printer.
That printer could only produce plastic objects, though, which Wilmore used to craft a faceplate for its own casing.
While we're still many moons away from building self-sufficient space habitats with objects created in situ, this test is a fascinating look into what humans can build for themselves in zero gravity — and a nice reminder that there are broader horizons beyond our Terran foibles.

The Webb telescope found something exceedingly rare around a dying star
The Ring Nebula is a well-known space icon shaped like a doughnut about 2,500 light-years away in the constellation Lyra. But astronomers think it's been holding a secret that only the penetrating gaze of the James Webb Space Telescope, a joint project of NASA and the European and Canadian space agencies, could reveal. Using Webb's infrared-sensing MIRI instrument, scientists got a clear sightline to the small but scorching star at its center. The shriveled core — a white dwarf — is all that remains of the star on its deathbed, having molted its outermost layers. When researchers zoomed in, they got a surprise. Surrounding the withering star was a disk of dust, much like the kind found around new stars that are in their prime planet-birthing years. It was kind of like seeing a pregnant octogenarian in a nursing home. This is just the second time scientists have observed such a disk around a star at the end of its life. And though they can't actually see baby planets in their nebula images, they are now wondering if these space environments could trigger a second generation of planets, long after the original brood of worlds formed around the star. The discovery, published in The Astrophysical Journal, is "raising questions about their nature, formation, longevity, and potentially a second phase of planet formation," the authors wrote.

Unlike giant stars that explode into a supernova and collapse into a black hole when their time is up, a medium star gradually runs out of nuclear fuel and suffers a more prolonged death. These stars, like our midsize sun in perhaps 5 billion years, decline into so-called planetary nebulas, a confusing misnomer for the phenomenon because they have more to do with aging stars than planets. Scientists have discovered a few thousand planetary nebulas in the Milky Way. Those include the Ring Nebula, aka NGC 6720 and Messier 57. With Webb, the researchers could see a compact dust cloud around the central white dwarf creating it. "These are first seen as the gas-and-dust-rich planet-forming disks in young stellar objects, and are an integral part of the star formation process itself," the authors wrote. "Remarkably, dusty disks or disk-like structures manifest themselves again as these stars reach the ends of their lives." Such a rare sighting is believed to have happened once before, when astronomers got a look at the Southern Ring Nebula with Webb, at wavelengths far beyond what people can see with their eyes. In the first images, astronomers were amazed to spot the true source of the nebula, said Karl Gordon, an astronomer at the Space Telescope Science Institute in Baltimore. "We knew this was a binary star (beforehand), but we effectively didn't really see much of the actual star that produced the nebula," he said during a 2022 news conference. "But now in MIRI, this star glows red because it has dust around it." The James Webb Space Telescope spots a dusty disk around the central white dwarf powering the Ring Nebula. Credit: NASA GSFC / CIL / Adriana Manrique Gutierrez illustration The dust cloud around the Ring Nebula is composed of tiny grains of amorphous silicate, a glass-like substance, according to the new paper. These particles are miniscule, perhaps less than one-thousandth the thickness of a human hair. The cloud itself stretches thousands of times wider than the distance between the Earth and the sun. The researchers noticed something else intriguing at the center of the nebula. The white dwarf's brightness keeps changing. That might be a clue that another star is lurking in the shadows nearby, perhaps a small-but-feisty red dwarf star. While scientists haven't directly spotted the buddy yet, they can infer it's there from patterns in the nebula. The study could help confirm earlier findings that suggested the star had two companions — one far in the outskirts of the system and another nearby. A close star could explain the strange arcs and rings seen around the nebula.

European Mars orbiter spies crumbling crater 'soaked in layers of Martian history' (photo)
When you buy through links on our articles, Future and its syndication partners may earn a commission. A European Mars probe captured a stunning view of a Martian crater that's rich in many of the features that help scientists reconstruct the planet's dynamic history over billions of years. The image, taken in October 2024 using the High Resolution Stereo Camera (HRSC) on the European Space Agency's (ESA) Mars Express orbiter, shows a crumbling crater called Deuteronilus Cavus. It is "soaked in layers of Martian history," having been exposed to volcanic lava flows, erosion from liquid water, repeated freeze-thaw cycles that expanded its edges, and layers of wind-blown volcanic dust settling over time, according to a statement from the space agency. Located in a transitional zone between the planet's rugged southern highlands and smoother northern lowlands, Deuteronilus Cavus is believed to originally have formed following an impact roughly 4.1 to 3.7 billion years ago, when Mars and other planets were being bombarded by huge numbers of asteroids and comets. Over time, the nearly circular 75-mile-wide (120 kilometers) depression has been eroded by water and ice, enlarging it to nearly twice its initial size. ESA shared a fun "recipe" outlining the series of events that shaped the crater, offering valuable insights into the planet's climatic and geological evolution. For example, the presence of clay minerals indicates past interactions between volcanic materials and water, hinting at the possibility of ancient habitable environments, according to the statement. This is further supported by channels cut through the crater's rim, likely formed by surface water flow or the collapse of weakened ground above draining subsurface water. Meanwhile, grooves in the crater rim suggest that ice once formed when Mars' axis tilted more sharply away from the sun than it does now. Related Stories: — Mars: Everything you need to know about the Red Planet — Facts about ESA's Mars Express orbiter — What happened to all the water on Mars? Here's why the debate continues "The linear grooves indicate where boulders frozen into the base of a glacier were dragged along, gouging out the troughs visible today," ESA officials said in the statement. "Around the base of the crater's inner walls, we can see the smooth, tongue-shaped ends of rock-covered glaciers. These 'debris aprons' formed when ice mixed together with rocky debris along the crater walls during a period of glaciation, and slowly crept downslope." The crater's interior also exhibits a mix of rock knobs, mesas, channels and plains, believed to be remnants of a collapsed central peak. Dark volcanic ash covers much of the crater floor, while surrounding wrinkle ridges mark ancient lava flows. "This feature-rich crater has all the ingredients for exploring Mars' varied geological processes, giving us a tantalizing taste of its complex history," ESA officials said in the statement.

Canadian, European space agencies reaffirm relations amid political, economic anxiety
LONGUEUIL - The Canadian and European space agencies say economic and geopolitical turmoil are forcing them to work closer together. Leaders at both organizations signed a joint statement today at Canadian Space Agency headquarters south of Montreal reaffirming their co-operation. Josef Aschbacher, director general of the European Space Agency, says space programs are having to contend with economic uncertainty and global conflicts. His visit comes as the United States is pressuring NATO members to increase their spending on defence — a sector of the economy that is tightly linked to space. As well, Aschbacher says the United States' space agency — NASA — could be facing deep budget cuts. Canadian Space Agency president Lisa Campbell says that in uncertain times it's important to reaffirm relationships with like-minded allies. This report by The Canadian Press was first published June 6, 2025.
