Big Bang: How We Are Trying to ‘Listen’ to It—and the New Physics It Could Unveil

Exactly what happened at the beginning of the universe, 14 billion years ago, is one of the greatest mysteries in physics; there’s no simple way to probe it. That’s because, in its early stages,...

New Type of Stellar Explosion Could Explain the Mystery of the Milky Way’s Elements

Until recently it was thought neutron star mergers were the only way heavy elements (heavier than zinc) could be produced. These mergers involve the mashup of the remnants of two massive stars in a...

‘Laws of Nature Turned up to 11’: Astronomers Spot Two Neutron Stars Being Swallowed by Black Holes
