Cosmology

Anomalies in the universe's relic radiation could contradict the evidence for a level cosmos

Researchers calculate that the planet will leave the sun's "habitable" zone in about 1.75 billion years

Force-carrying "gravitons" with mass could help to explain the universe's accelerating expansion

A budget struggle has the world's largest steerable radio telescope making sacrifices in the name of science

If particles of light have mass, a small but distinct possibility, they may not live forever—and some fundamental theories would have to be modified, too

The B-mode polarization signal provides a way for astronomers to calculate neutrino masses, as well as to chase a class of "primordial" B-modes that could be used to confirm inflation

Theory said that muon neutrinos could transform into electron neutrinos. A neutrino detector confirms this by catching many more electron neutrinos than it should have otherwise. John Matson reports

Physicist Dave Goldberg breaks down the mysteries of the cosmos in his new book The Universe in the Rearview Mirror. In an excerpt, Goldberg explores the matter-antimatter divide

Ultrafast, ultrabright radio pulses from sources unknown could help map intergalactic matter, but only if astronomers can figure out their origin
