Physicists have been asking an awkward question for decades. If the universe is built from invisible fields, why has each one ended up in the state we find it in, and not in some other? A team at the University of Portsmouth, working with colleagues at Syracuse University and the École Normale Supérieure in Paris, […]

Long ago, the patch of sky that would become our galactic neighbourhood looked nothing like a galaxy. It was a collection of thousands of smaller galaxies. Some were turning out stars at a frantic pace, others held nothing but gas, and others were littered with dead stars and black holes. That is the picture drawn […]

In April 2009, newspapers around the world ran a headline that read like a cocktail menu: the center of the galaxy tastes of raspberries and smells of rum. The line came from the Guardian, which built it from a press release by the Max Planck Institute for Radio Astronomy in Bonn. The release was much […]

An international team of astronomers has published a detailed study of VT J1906+0849, a radio source discovered in the VLASS survey (Very Large Array Sky Survey) that doesn’t resemble anything else previously catalogued in the Milky Way. The paper, led by Jessie M. Miller of the California Institute of Technology, combines radio, infrared, optical, and […]

For the first time, astronomers have pointed NASA’s two flagship space telescopes at the same patch of sky beyond Neptune and let them work as a team. Hubble handled the visible light. Webb handled the infrared. Together, they picked out 27 previously unknown trans-Neptunian objects, or TNOs — small, icy bodies that drift in the […]
