For years, scientists were baffled by Kappa Tucanae A. Dust this close to a star should be vaporized or blown away by radiation pressure almost instantly. Yet, it persists. Using the MATISSE instrument on the European Southern Observatory's interferometer, the team found the answer: a companion star.

Using ESA's XMM-Newton satellite, astronomers have peered through the dust of a distant galaxy to find a hidden monster at its core. NGC 3221 is a luminous infrared galaxy located 200 million light-years away. Previous observations hinted that something powerful lurked at its center, but the galaxy's "edge-on" orientation means we look through layers of gas and dust that block visible light.

Why do gels age? Why does sauce separate? A new lab on the International Space Station uses lasers to study the hidden "slow motion" of soft matter without the interference of gravity. On Earth, studying soft materials (like gels, glasses, or emulsions) is difficult because gravity pulls heavier particles down. This "sedimentation" masks the subtle internal restructuring processes that determine a product's shelf life.

Mars is hostile. With temperatures plunging to -90°C, thin air, and radiation, building a shelter is the first priority. But transporting construction materials from Earth is prohibitively expensive. The solution is ISRU (In Situ Resource Utilization). We must build with what we find: Regolith (Martian soil). But loose dust doesn't make a wall.

On the reddish-orange surface of Jezero Crater, NASA's Perseverance rover spotted something unusual: bright white rocks scattered like breadcrumbs. Analysis confirms these are Kaolinite—a clay mineral that, on Earth, forms primarily in tropical rainforests.

New balloon-mounted probes have captured the strongest radiation spike at aviation altitudes in 20 years, confirming the reach of a major X5 solar flare. The solar flare on November 11, 2025, was an X5 class event. It triggered a Ground Level Enhancement (GLE), meaning energetic particles punched through the atmosphere all the way to the surface.

Astronomers long assumed brown dwarfs behaved like Jupiter: stable, banded stripes of wind. But Western University's Stanimir Metchev and team found something different. Using the James Webb Space Telescope, they observed VHS 1256B, a "super-Jupiter" 10x heavier than our own. It showed extreme fluctuations in brightness, suggesting a violently changing atmosphere.

Billions of years ago, Mars was wet. A new study maps 16 massive river basins that may have been the planet's best cradles for life. Researchers from UT Austin, led by Abdallah S. Zaki and Timothy A. Goudge, didn't discover new rivers. Instead, they did something simpler but profound: they connected the dots. By piecing together existing maps of valley networks, lakes, and canyons, they identified 16 massive watersheds exceeding 100,000 km².

Every launch leaves a mark. Scientists now argue that the principles of Reduce, Reuse, and Recycle must apply to the final frontier before it becomes a graveyard. Transitioning to a circular economy requires more than just better rockets. It requires data. The authors highlight the need for AI systems to track spacecraft health and predict failures before they happen.

Searching for moons light-years away is incredibly difficult. To have a fighting chance, David Kipping and his team targeted Kepler-167e. It is one of the closest Jupiter analogues ever found: 0.91x Jupiter's mass, orbiting at 1.88 AU. Since our Jupiter has nearly 100 moons, this planet seemed like the perfect hiding spot for an exo-Ganymede.

Astronomers have detected massive streams of helium escaping from the "super-puff" exoplanet WASP-107b. Discovered in 2017, WASP-107b is an anomaly. It is roughly the same size as Jupiter, but has only one-tenth of the mass. This extremely low density gives it a "fluffy" atmosphere that extends far out into space, making it much easier for the host star's radiation to strip away gas.

Astronomers confirm a rare cosmic pairing: a dying star's ghost (Planetary Nebula) caught lingering inside a bustling star cluster. Planetary nebulae in open clusters are incredibly rare. To verify the membership, the team led by Vasiliki Fragkou analyzed motion and light data.
