Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions – one of their tried-and-true tools for studying the mysterious…
Astronomers have discovered two pairs of quasars in the distant Universe, about 10 billion light-years from Earth. In each pair, the two quasars are separated…
Simulations of a region of space 100 million light-years square. The leftmost simulation ran at low resolution. Using machine learning, researchers upscaled the low-res model…
