You’re in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality headsets the crew use for rest & relaxation, oxygen and fuel generation, and water. All this from converting the Martian atmosphere into workable electricity.

Scientists at the Max Planck Institute for Solar System Research have produced the most detailed simulations ever of solar prominences. These vast clouds of cooler plasma suspended in the Sun's scorching outer atmosphere have often perplexed solar astronomers. Their research reveals that two separate processes work together to keep these structures alive, and could one day help us predict the violent eruptions that drive dangerous space weather here on Earth.

Our Galaxy's halo of hot gas is measurably warmer on one side than the other and a team of scientists have found the culprit. The gravitational pull of the Large Magellanic Cloud is drawing the Milky Way slowly southward, compressing the gas in its path and heating it up, much like a piston in an engine. The discovery solves a puzzle that has intrigued astronomers since the temperature difference was first detected in 2024.

Where exactly is the edge of the Milky Way? That question is harder to answer than one might expect. Since we’re inside of the galaxy itself, it’s obviously hard to judge the “edge” to begin with. But it gets even more complicated when defining what the edge even is - the galaxy simply gets less dense the farther away from the center it goes. A new paper by researchers originally at the University of Malta thinks they have an answer though. The “edge” can be defined as the star-forming region, and in their paper, published in Astronomy & Astrophysics, they very clearly show that “edge” to be between 11.28 and 12.15 kiloparsecs (or about 40,000 light years) from the center.

The 570 megapixel Dark Energy Camera captured this image of the iconic Sombrero Galaxy. The galaxy has characteristics of both elliptical galaxies and spiral galaxies, and is likely the result of multiple mergers and cannibalizations of dwarf galaxies. A faint stellar stream, only fully traced a few years ago, is revealed by DECam's resolving power.

NASA and other space agencies spend a lot of time and money considering the cleanliness of their missions. Billions of dollars are spent in and on cleanrooms every year, with the express effort of ensuring both that the equipment operates without interference, but also that we don’t accidentally contaminate our exploration target with life from Earth itself. So far, we have primarily focused on bacteria in our efforts to stop this contamination, but according to a new paper by Atul M. Chander of NASA Jet Propulsion Laboratory and his co-authors, we might be missing an entirely different threat - fungi.

Using nothing but a laser beam, scientists at Texas A&M University have demonstrated that tiny engineered devices can be lifted and steered in three dimensions without any physical contact. This breakthrough could one day form the basis of a propulsion system capable of reaching our nearest neighbouring stars in decades rather than centuries.

Researchers at the Institute of Science Tokyo have developed an origami inspired foldable antenna for CubeSat satellites that weighs just 64 grams yet in orbit, it deploys to two and a half times its stowed size. The antenna folds away neatly for launch and deploys automatically in space, achieving high gain communications performance from a package small enough to fit in your pocket and could one day support missions as far away as the Moon.

Space travel has taught us valuable lessons for living and working in outer space, specifically regarding how microgravity (often mistakenly called zero-gravity) impacts the human body during short- and long-term spaceflight. This includes decreased muscle and bone mass, fluid shifts, reduced heart rate, psychological health, compromised immune system, and radiation exposure. But with agencies like NASA aspiring to build a lunar base and establish a long-term presence on the Moon, and eventually Mars, how could space travel impact potentially having babies in space?

The Milky Way has a sizable retinue of dwarf galaxies, and they may hold important clues about conditions in the early Universe. However, they're difficult to observe because many of them are so faint. The tiniest ones are called Ultra-faint dwarf galaxies, and a new simulation aimed at how they form is showing how these faint collections of stars and gas mirror the conditions of the early Universe.

These images, released on April 14, 2026, show two open star clusters, Trumpler 3 (left) and NGC 2353 (right). They represent a recent study from NASA’s Chandra X-ray Observatory that shows how young Sun-like stars are dimmer in X-rays than previously thought. This latest study looked at eight clusters of stars between the ages of […]

A team of scientists at the University of Virginia is using a telescope in Arizona to study cosmic structure and the result is the largest 3D map of the Universe ever created. The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory is their tool, and the ultimate goal is to get a handle on the mystery of dark energy by charting the positions of galaxies.

The planet Uranus is a weird place. Not only does it roll around the Sun on its side once every 84.3 Earth years, it also sports a spindly set of rings corralled in some places by strange little moons. Two of those rings, the μ (mu) and ν (nu) rings are incredibly faint, which makes them challenging to study.

Einstein told us that massive objects bend light and he was of course, right. Across the universe, giant galaxies are acting as natural telescopes, warping and distorting the light of objects behind them into spectacular arcs and rings. Now the Euclid space telescope wants your help to find them and the scale of the hunt is unlike anything attempted before.

If humans are ever going to live permanently on Mars, someone is going to have to work out where all the raw materials, the food, they oxygen or the material for the structures to name just a few. A new study has tackled that unglamorous but absolutely critical question and the answer involves robots, asteroids, and one of the most complex supply chains ever designed.

NASA's planet hunting telescope has been busy. A new study has just sifted through the light of over 83 million stars and emerged with more than 11,000 potential worlds, including a confirmed giant planet orbiting a distant star. The results don't just add to our catalogue of planets. They fundamentally change where we look for them.

On April 17th, engineers at NASA's Jet Propulsion Laboratory (JPL) sent commands to shut down an instrument aboard Voyager 1 called the Low-energy Charged Particles experiment, or LECP. The nuclear-powered spacecraft is running low on power, and turning off the LECP is considered the best way to keep humanity's first interstellar explorer going.

ASTEP, the Antarctic Search for Transiting ExoPlanets, a small visible telescope operating at Concordia station, continues making a real impact in characterizing odd new exoplanetary systems.

The giant planets in our solar system—Jupiter, Saturn, Uranus, and Neptune—have challenged our understanding of planetary formation and evolution. Specifically, their atmospheric formations and compositions have provided awe-inspiring images from spacecraft and given scientists key insights into the interior mechanisms of these massive worlds. But what about exoplanets? What can their atmospheres teach scientists about their formation, evolution, composition, and interior mechanisms? And how do longstanding exoplanet models stack up against the real thing?

It turns out that even after studying our solar system in depth and discovering more than 6,100 exoplanets across more than 4,500 exoplanetary systems, not all solar systems are created equal. The longstanding notion is that planets orbit almost entirely in the same orbital path, also called an orbital plane. But what if an exoplanetary system was found to have exoplanets that not only orbit in different planes, but also exhibits changing behavior regarding when they pass in front of their star?
