Giant Zombie Atoms of the Cosmos
In neutron stars, astrophysicists see a form of matter like none other.
Why These Researchers Are Drawn to the World’s Edge
The joy and toll of doing remote science.
Quantum Correlations Reverse Thermodynamic Arrow of Time
A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
Neutrinos Suggest Solution to Mystery of Universe’s Existence
Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.
Ultra-Powerful Radio Bursts May Be Getting a Cosmic Boost
Repeating radio bursts are among the most mysterious phenomena in the universe. A new theory explores how some of their puzzling properties can be explained by galactic lenses made of plasma.
Cookie-Cutter Supernovas Might Come in Different Flavors
Astronomers thought that all Type Ia supernovas shine with the same brightness, making them incredibly useful cosmic yardsticks. But uncertainty over what causes these explosions has led researchers to reconsider their assumptions.
