We summarize the week's scientific breakthroughs every Thursday.
Pulsating remnants of stars hint at a clump of invisible matter thought to be about 10 million times the sun’s mass.
Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.
As the threat of falling spacecraft increases, using earthquake sensors to detect the effects of their sonic booms could better map trajectories.
At 3.3 billion light-years across, the ring may challenge the “cosmological principle” that the universe looks uniform at sufficiently large scales.
Among the first finds from the Vera C. Rubin Observatory, the discovery hints at a population of exceptionally strong asteroids.
The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.
Trees are known for absorbing CO2. But microbes in their bark also absorb other climate-active gases, methane, hydrogen, and carbon monoxide.
The subatomic particles are incredibly numerous. About 1,000 neutrinos from stars other than the sun pass through a thumbnail every second.
The wake left by Betelgeuse’s companion could solve a decades-old mystery of its strange brightness cycles.
