Astronomers have discovered phosphine gas in the atmosphere of an ancient brown dwarf, Wolf 1130C, using the James Webb Space Telescope. The finding is puzzling because phosphine, a potential biosignature, has been missing from other similar objects. ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe's structure. The findings align with recent DESI observations, offering the strongest evidence yet for an evolving cosmic force.

NASA's Cassini mission has revealed surprising heat flow at Enceladus' north pole, showing the moon releases energy from both ends. This balance of heat could allow its subsurface ocean to remain liquid for billions of years, supporting conditions .. ...

Stanford scientists found that strontium titanate improves its performance when frozen to near absolute zero, showing extraordinary optical and mechanical behavior. Its nonlinear and piezoelectric properties make it ideal for cryogenic quantum ...

Researchers have discovered quantum oscillations inside an insulating material, overturning long-held assumptions. Their work at the National Magnetic Field Laboratory suggests that the effect originates in the material's bulk rather than its surface ...

A team at the University of Stuttgart has engineered a compact short-pulse laser that achieves up to 80% efficiency--far surpassing current models. Their new multipass design reuses light within a small crystal, combining power and precision in a ...

MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic ...

Researchers are using black hole shadows to challenge Einstein's theory of relativity. With new simulations and future ultra-sharp telescope images, they may uncover signs that his famous equations don't tell the whole story.

A colossal black hole 10 billion light-years away has been caught devouring one of the universe's biggest stars, unleashing a flare 30 times brighter than any seen before. The flare, detected by Caltech's ZTF, likely marks a tidal disruption event -- ...

Using CERN's Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed stable, suggesting plasma instabilities aren't responsible for missing gamma rays. Instead, the data strengthens the idea of ...
