“Pre-supernova” Neutrinos: What Happens Before a Star Explodes and Dies?
A recent study on ‘pre-supernova’ neutrinos—tiny cosmic particles that are extremely hard to detect—has brought scientists one step closer to understanding what happens to stars…
New Research on Optomechanical Technology That Can Enhance Gravitational-Wave Detectors
Gravitational wave detectors are extremely complex instruments of precision measurement. They use interference as the physical mechanism to measure passing gravitational waves (GWs)—ripples in space-time—from…
Dancing Stars and Black Holes in a Cosmic Cloud of Gas: Investigating the “Common Envelope Phase”
Most massive stars are born in binaries (and sometimes triples, quadruples, and so on—being single isn’t common for such rock stars!) As stars age, they…
Lost 8 Billion Light Years of Universe Evolution Revealed by Gravitational Waves
Every year, 2 million black hole mergers are missed — Australian scientists work out how to detect them, revealing a lost 8 billion light-years of…
