The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has shown for the first time that it can detect the faint glow of hydrogen gas from deep in the universe's past using only its own data.
Researchers at the DarkSide collaboration have unveiled results from a seven-year experiment that tested whether dark matter particles could exist as composites of smaller, elementary particles. While the search turned up ...
Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas. Every large galaxy, including the Milky Way, is wrapped in a huge envelope of gas called the circumgalactic medium, or CGM. ...
The cosmic microwave background (CMB) is the universe's oldest light, leftover thermal radiation from about 380,000 years after the big bang. Maps of the CMB offer a picture of the "baby universe" as it was 13.8 billion years ...
Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications?
The origins of the earliest life on Earth, prior to the rise of oxygen and photosynthesis, remain a mystery. Graveyards in brine pools at the bottom of the Red Sea may hold some answers.
A drop of coffee on a tabletop often leaves a dark ring behind. This everyday mark is a reminder that a drying droplet is not passive: As water evaporates, it can transport the particles suspended inside it toward the edge. ...
Around 631,000 years ago—a geological blink of an eye—catastrophe unfolded in what is now northwestern Wyoming, U.S. During what is thought to have been a series of immense volcanic eruptions, life within hundreds of kilometers ...
An international research team has reported the first experimental investigation of a nuclear physics reaction essential for understanding how the element strontium is produced in stars—specifically in stellar environments ...
When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, ...
