NASA’s Quesst mission marked a major milestone with the start of tests on the engine that will power the quiet supersonic X-59 experimental aircraft.

These engine-run tests, which began Oct. 30, allow the X-59 team to verify the aircraft’s systems are working together while powered by its own engine. In previous tests, the X-59 used external sources for power. The engine-run tests set the stage for the next phase of the experimental aircraft’s progress toward flight.

Habitable Zones Aren’t Always Safe Havens: The Hidden Cosmic Perils Facing Potential Life

Posted by in category: alien life

When considering the potential for life on exoplanets, scientists often focus on the habitable zone, the region around a star where conditions might allow liquid water to exist. However, new research suggests that this concept alone oversimplifies the dangers these planets face. It’s not just about being in the right place; it’s also about avoiding interstellar chaos.

While identifying exoplanets in the habitable zone is a crucial step in the search for extraterrestrial life, their environments can be treacherous. In a study soon to be published in The Astronomical Journal, researchers led by Tisyagupta Pyne from Visva-Bharati University highlight the threats lurking in dense stellar neighborhoods. Stellar flybys and catastrophic supernovae explosions have the power to disrupt entire planetary systems, stripping atmospheres or ejecting planets into interstellar space.

Achieving the “Impossible”: Nuclear Physicists Are Closer Than Ever to the Elusive Double Magic Nuclei

Posted by in categories: materials, particle physics

Advancements in nuclear physics may soon enable the creation of stable, superheavy nuclei, paving the way for new materials and insights into atomic stability.

A team of scientists has made significant advancements in the quest to create new, long-lasting superheavy nuclei. These double magic nuclei, which have a precise number of protons and neutrons that form a highly stable configuration, are exceptionally resistant to decay. Their research could deepen our understanding of the forces that bind atoms and pave the way for the development of new materials with unique properties. This work brings us a step closer to the so-called “Island of Stability,” a theoretical region in the nuclei chart where it’s believed some nuclei could exist far longer than those created so far.

The study, led by Professor Feng-Shou Zhang, has predicted promising reactions between different elements that could be used in experiments to create double magic nuclei. One key discovery involves a reaction between a special type of radioactive calcium isotope and a plutonium target, which could produce the predicted double magic nuclei 298 Fl. Another potential double magic nuclei, 304 120, could be created by combining vanadium and berkelium, although this reaction is currently less likely to succeed.
