For Astronomers, Neutron Star Merger Could Eclipse Eclipse
Even as the solar eclipse was mesmerizing millions, astronomers were training their space- and land-based telescopes on a far more violent astrophysical event.
Scientists Unveil New Inventory of Universe’s Dark Contents
The first major results from the Dark Energy Survey signal the start of a new era of cosmology.
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.
Lucky Break Leads to Controversial Supernova Discovery
Supernova hunters were able to train their telescopes on a recent eruption just hours after it exploded. What they found only adds to the growing list of questions surrounding these cosmic blasts.
Strange Noise in Gravitational-Wave Data Sparks Debate
The team that discovered gravitational waves put their data online. Now an independent group of researchers claims that they’ve found what might be a serious problem.
Researchers Check Space-Time to See if It’s Made of Quantum Bits
The newly developed theory of emergent gravity, proposed as an alternative to dark matter, struggles in one of its first trials.
Rainer Weiss, Remembering the Little Room in the Plywood Palace
The physicist who designed the LIGO experiment that detected gravitational waves still holes up in a small basement lab surrounded by electronics and optical instruments.
How Superfluid Dark Matter Mimics an Old Idea About Gravity
Does the force of gravity change at large scales? Perhaps not, but a new theory of dark matter shows why that could appear to be the case.
