The big news in physics last week was the discovery of a faint line of gas elements in x-ray data that came from studying the space between galaxies—it didn't correspond to any known element. The team believes it's possible ...
(Phys.org) —The surface of Mars is full of activity, with dust storms, dust devils, and drifting dunes in constant motion. Scientists suspect that similarly rich activity may exist underneath the surface, even though it ...
On Sept. 5, 2022, NASA's Parker Solar Probe soared gracefully through one of the most powerful coronal mass ejections (CMEs) ever recorded—not only an impressive feat of engineering, but a huge boon for the scientific community. ...

The Rosetta orbiter spectrometer for ion and neutral analysis (ROSINA) instrument orbited comet 67P to revolutionize our understanding of cometary material composition. A key finding of the satellite was to explore the composition ...
An international team of astronomers reports the detection of a new, hot-dust-obscured galaxy (DOG). The galaxy, which received designation WISE J190445.04+485308.9, was found at a relatively low redshift of 0.415, which ...
An international team of astronomers has used the James Webb Space Telescope (JWST) to observe a luminous dusty star-forming galaxy known as GN20. Results of the observational campaign, published April 26 on the arXiv preprint ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has performed high-resolution observations of an M-dwarf star known as 2MASS J04124068+2438157. Results of the observational ...
In 2017, a mysterious comet dubbed 'Oumuamua fired the imaginations of scientists and the public alike. It was the first known visitor from outside our solar system, it had no bright coma or dust tail, like most comets, and ...

Dust is a general name for minute solid particles with diameters less than 20 thou (500 micrometers). Particles in the atmosphere arise from various sources such as soil dust lifted up by wind, volcanic eruptions, and pollution. Dust in homes, offices, and other human environments consist primarily of human skin cells, but also contain small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, and many other materials which may be found in the local environment.
