When neutron stars merge, they create a powerful explosion called a kilonova that flings out neutron-rich material, some of which decays into heavy elements through a process called the r-process. Recent observations of kilonovae revealed […]
This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic […]
More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio Ciufolini at […]
Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries […]
The planets that appear most common in the universe could have a lot of water—but it could be hiding where telescopes can’t detect it, according to a new study led by scientists with the University […]
The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data […]
Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential […]
Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.This post was originally published […]
Since gravitational waves were first detected in 2015, instruments including LIGO, Virgo and KAGRA have picked up a steady stream of signals from colliding black holes, building a catalog that now numbers in the hundreds. […]
The Euclid space telescope has spotted the oldest quasars—the brightest objects in the universe—ever discovered, deepening a cosmic mystery that has been puzzling scientists.This post was originally published on this site
