3D Printing on the Moon: A Breakthrough for NASA’s Artemis
2026/03/03 | 42 mins.
Scientists at The Ohio State University have used 3D printing to transform simulated lunar soil into durable, heat-resistant components.

The study shows how environmental conditions and base surfaces affect structural strength—key insights for missions like NASA’s Artemis program.

By leveraging local resources and solar-powered systems, future missions could build habitats directly on the Moon, advancing both deep-space colonization and sustainable manufacturing on Earth.

Inside the Sun’s Turbulent Plasma Ocean
2026/03/02 | 22 mins.
Using data from total solar eclipses, researchers at the University of Hawaiʻi uncovered turbulent plasma structures in the Sun’s outer atmosphere, including vortex rings and wave instabilities. These disturbances persist as they move outward, helping generate the solar wind.

This episode explores how eclipse observations refine our understanding of solar energy transfer and improve predictions of space weather that can disrupt satellites, communications, and power grids.

Hidden Glaciers on Mars? The Hecates Tholus Discovery
2026/03/01 | 29 mins.
Scientists have identified Hecates Tholus, a volcano on Mars, as a potential site for massive underground glaciers buried beneath volcanic debris. By comparing it to Deception Island, researchers found geological features — including crevasses and push moraines — that suggest moving ice beneath the surface.

If confirmed, accessible equatorial ice could transform future human exploration and reshape planetary protection policies. The study also points to volcanic activity as a key factor in preserving ancient water reserves on the Red Planet.

A Planet That Shouldn’t Exist? The LHS 1903 Mystery
2026/02/28 | 31 mins.
Astronomers studying LHS 1903 have discovered a planetary system that defies traditional formation models. Instead of a distant gas giant, the outermost planet is rocky — contradicting the standard view that solid worlds form close to their stars while gaseous giants form farther out.

Researchers propose an inside-out, sequential formation process, where early atmospheric gases were depleted before the final planet formed. The finding forces a reassessment of how and when planets assemble — and highlights the growing diversity of planetary systems across the galaxy.

Hubble Discovers a Galaxy Made Almost Entirely of Dark Matter
2026/02/27 | 30 mins.
Using the Hubble Space Telescope and other observatories, astronomers have confirmed CDG-2, a rare galaxy in the Perseus Cluster composed of roughly 99% dark matter. With almost no visible stars or gas, the object was identified by tracking its globular clusters — gravitational clues revealing a hidden structure.

Researchers suggest its star-forming material was stripped away by nearby galaxies. The discovery showcases advanced statistical methods and machine learning techniques that may soon reveal many more of these “ghost” galaxies.
