(Phys.org) -- While the largest contributor to anthropogenic greenhouse gas emissions is the power industry, the second largest is the more often overlooked cement industry, which accounts for 5-6% of all anthropogenic CO2 ...
Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type ...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), Italian astronomers have investigated an active galaxy known as Markarian 509. Results of the study, presented in a paper published July 14 on arXiv.org, deliver ...
Carbon monoxide detectors in our homes warn of a dangerous buildup of that colorless, odorless gas we normally associate with death. Astronomers, too, have generally assumed that a build-up of carbon monoxide in a planet's ...

Using Atacama Large Millimeter/submillimeter Array (ALMA), researchers have conducted interferometric observations of the elliptical galaxy NGC 3557 to investigate molecular gas emission from this source. Results of these ...
The chemical composition of gases emitted from volcanoes—which are used to monitor changes in volcanic activity—can change depending on the size of gas bubbles rising to the surface, and relate to the way in which they ...
