Stars don't form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre ...

Particle emissions and secondary aerosol formation from internal combustion engines deteriorate air quality and significantly affect human wellbeing and health. Both the direct particle emissions and ...

Despite decades of searching, scientists still haven’t found the elusive substance that holds galaxies together: dark matter.

A distant cluster of galaxies is wrapped in a vast halo of high-energy particles that could be the work of supermassive black ...

Particle deposition in the small bronchial tubes (generations six through twelve) is strongly influenced by the vortex-dominated secondary flows that are induced by axial curvature of the tubes. In ...

Stretching across 7.6 sextillion miles of space, astronomers crown it the new 'largest structure in the universe' ...

From living matter to molecules to elementary particles, the world is made of “chiral” objects that differ from their ...

The paper describes the development of insulation structure and enhancement of insulation reliability of 500 kV DC GIS (gas insulated switchgear). Considering problems of metallic particles and charge ...

Thus, self-compacting concrete with high-strength grades requires appropriate particle and grain dispersion at each hierarchical structural level. Scanning electron microscopy, thermography, and X-ray ...

Abell 2255 is a cluster containing between 300 and 500 constituent galaxies, many of which are merging. It's located around 800 million light-years from Earth and spans around 16.3 million light-years ...
