NASA Fires Up Nuclear Future for Deep Space Travel

NASA has completed its first major testing of nuclear reactor hardware for spacecraft propulsion in over 50 years, marking a crucial step toward faster, more capable deep space missions. Engineers at Marshall Space Flight Center conducted more than 100 ‘cold flow’ tests on a full scale reactor engineering development unit throughout 2025, gathering vital data on how propellant flows through the system under various conditions.

The Star That Wasn't Dying After All

Astronomers have solved a bit of a mystery that had them questioning whether one of the most extreme stars ever observed was about to explode. WOH G64, a massive red supergiant in the Large Magellanic Cloud, began behaving so strangely that researchers suspected it had evolved into a rare yellow hypergiant on the brink of supernova. But new observations from the Southern African Large Telescope reveal the star is still very much a red supergiant, yet still exhibiting strange behaviour.

Finding A Frozen Earth In Old Data

Finding Earth-like planets is the primary driver of exoplanet searches because as far as we know, they're the ones most likely to be habitable. Astronomers sifting through data from NASA's Kepler Space Telescope have found a remarkably Earth-like planet, but with one critical difference: it's as cold as Mars.

The Milky Way's Center is a Difficult Target, But It Can't Deter the Roman Telescope

The Milky Way's Galactic Center and Bulge are shrouded in thick dust and tightly-packed with stars. It's a tough region to observe, but the Nancy Gracy Roman Space Telescope is built for the task. Its Galactic Bulge Time-Domain Survey will find more than 100,000 exoplanets, along with stars, black holes, neutron stars, and even rogue planets.
