Cosmic filaments help set first limits on dark matter's decay into gravitons

Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York ...

Uranus's unusual rotation makes its bow shock expand and contract each day

Within our solar system, Uranus is a geometric oddball. Its spin axis tilts more than 90° from its orbit, so it essentially rolls on its side through space. In contrast, Earth and other planets tilt only moderately or not ...

JWST study suggests a handful of 'leaky' galaxies reionized the early universe

A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
