Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.

They are the toughest animals on Earth and possibly the key to surviving on Mars. Tardigrades, the microscopic creatures nicknamed 'water bears', have survived the vacuum of space, the crushing pressure of the deep ocean and temperatures that would kill virtually anything else. Now a new study has put them to work as unlikely pioneers, testing whether the hostile soil of Mars could ever support life and the results are full of surprises.

A visitor from another star system has just had its portrait taken by a spacecraft on its way to Jupiter and the image is superb. Comet 3I/ATLAS, only the third interstellar object ever discovered passing through our Solar System, has been captured in stunning detail by ESA's JUICE mission, revealing a glowing halo of gas, a sweeping tail, and hints of jets erupting from its ancient, icy heart. But the picture itself is just the beginning of the story.

SpaceX's Starship is the most powerful rocket ever built and it may be about to change everything. But researchers at the German Aerospace Centre have been asking a question: does Europe have an answer? Their new study, built on meticulous analysis of Starship's own flight data, suggests the answer is yes although it will require a fundamentally different approach, and a willingness to think differently.

Future farmers on the Moon and Mars will have a big challenge: how to grow healthy food in two extremely unhealthy environments. That's because the soil on both worlds isn't at all hospitable to plants and animals. Neither are other conditions. Both are irradiated worlds, Mars has a thin atmosphere and the Moon has none at all. So, how will future colonists on either world grow their food?

We've been waiting a long time for the Vera Rubin Observatory to begin its work. The observatory features the largest digital camera ever built. It'll create a time-lapse of the southern night sky for ten years with its 3.2 gigapixel camera. An untold number of discoveries awaits.

Astronomers have discovered a extraordinary celestial construction site hiding behind a natural magnifying glass in space and what they've found is unlike anything seen before. A cluster of at least 11 galaxies, all building stars at a ferocious rate in the early universe, has been caught in the act of becoming one of the most massive structures in the universe.

Astronomers have used a special class of ancient, pulsating stars as celestial lighthouses to map the earliest chapter of our Galaxy's life and what they've found is rewriting what we thought we knew about how the Milky Way was born. By building the largest ever catalogue of these stellar beacons and tracing their movements back billions of years, the team has uncovered surprising similarities between our Galaxy's earliest structures, and even found evidence of the same story playing out in our nearest galactic neighbour.

Scientists have built a working model of Earth without any life on it and what they found might change how we search for aliens. By simulating 4.5 billion years of our planet's evolution minus every bacterium, plant, and creature that ever existed, they've created a new tool for spotting genuinely habitable worlds among the thousands of rocky planets soon to be studied by the next generation of space telescopes.

As part of a Golden Age of exploration and discovery, NASA announced Friday the agency is increasing its cadence of missions under the Artemis program to achieve the national objective of returning American astronauts to the Moon and establishing an enduring presence.

Jupiter is the largest planet in the solar system and has proudly boasted about this since time immemorial, with its scientific confirmation occurring by Galileo Galilei in 1610. It was later found that Jupiter has a bulging equator caused by its rapid rotation, turbulent atmosphere, and complex interior mechanisms despite its massive size, and scientists have even measured its “waistline” down to a tenth of a kilometer. Now, imagine being the largest planet in the solar system and you’re told you’re not as big as you thought. Where probably most humans would be thrilled to find this out, how do you respond if you’re Jupiter?

The radio telescope LOFAR, with a major contribution from Leiden Observatory, has produced the most detailed radio map of the Universe ever made. Never before have so many cosmic radio sources been captured in a single survey: 13.7 million.

Researchers in Brazil have discovered another tektite field. Tektites are gravel-sized chunks of natural glass formed by impacts and spread over a wide area. Their presence indicates that a powerful impact occurred 6 million years ago.

Uranus is a planet that seems to roll around on its side as it orbits the Sun. That's because it's tipped over, with an axial tilt of 97.8 degrees. That weird tilt gave the James Webb Space Telescope (JWST) a chance to probe the ionosphere using the Near Infrared Spectrometer (NIRSpec) instrument. An international team of astronomers used the data to map the vertical structure of that region and detect faint auroral displays.

NASA’s Carbothermal Reduction Demonstration (CaRD) project completed an important step toward using local resources to support human exploration on the Moon.

Complex Organic Molecules (COMs) are important building blocks for life. They can form in space and be delivered to planets. But new research shows some of them can form in circumplanetary disks where moons form, boosting the prospects for life in Europa's ocean.

A dying star has ejected its outer layer and illuminated it with its powerful radiation. The resulting nebula looks every bit like a transparent human skull. Astronomers are calling the unusual structure the Exposed Cranium Nebula.

If skies are clear, don’t miss one of the top astronomical events of the year this coming Tuesday, March 3rd, as the Moon passes through the Earth’s shadow in a total lunar eclipse. This will be a fine leisurely affair centered around the Pacific Ocean region, with totality lasting almost an hour in duration. For many observers worldwide, this is the last total lunar eclipse until late 2028 and mid-2029.

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy (MPIfR) used data from the Atacama Large Millimeter/submillimeter Array (ALMA) to shed light on this open question of galaxy formation. They studied one of the most spectacular galaxy aggregations in great detail and published their results in the current issue of The Astrophysical Journal.

When MSL Curiosity was sent to Gale Crater, one of its goals was to study boxwork ridge features on Mt. Sharp. The rover has gathered its fourth sample from the rocks, and results are on their way. Previous samples showed tantalizing evidence in favour of ancient life on Mars. But we're still waiting for the extraordinary evidence required to conclude that Mars was once inhabited.
