A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.

Scientists have come up with a number of theories about the multiverse.
Some argue the Big Bang was a rebirth rather than a birth.
Plus, the tactics the food industry is using to boost sales of ultra-processed foods in middle-income countries. Listen to The Conversation Weekly.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Scientists have a good estimate on the staggering number of stars in the universe.
Gravity, mass and centrifugal force all contribute to the final shape of a planet.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
Machine learning is helping astronomers unravel the vast amounts of data being collected.
A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
Thanks to the discovery of five twinkling galaxies in a rare alignment, astronomers have been able to calculate — for the first time — the properties and geometry of an invisible gas cloud in space.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
Field theory describes the universe as energy flowing along unending lines. With this perspective, it is possible to define a new fundamental building block of matter.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
The term ‘Big Bang’ might make you think of a massive explosion. Put the thought out of your head. Rather than an explosion, it was the start of everything in the universe.
A study has suggested that the universe is curved like a sphere rather than flat, which may unleash a major crisis in cosmology.
Dark sky sites can inspire new generations of stargazers, but a better long-term solution would be connecting people with the night sky where they live.
Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil ‘dark matter’.
In an age when women were rarely allowed in observatories, Margaret Burbidge changed how we saw the stars.
