Commonwealth is trying to create fusion inside what's called a tokamak. Nuclear fusion, which would be a new source of carbon-free energy, melds two hydrogen atoms together to produce a helium atom and a lot of energy. (AP Photo/Steven Senne)

Summer Ship Tracks in the Pacific August 26, 2018 In August 2018, long, narrow clouds stood out against the backdrop of marine clouds blanketing much of the North Pacific Ocean. Known as ship tracks, the distinctive clouds form when water vapor condenses around the tiny particles emitted by ships in their exhaust. Ship tracks typically form in areas where thin, low-lying stratus and cumulus clouds are present. ... The Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua captured this natural-color image of several ship tracks extending northward on August 26, 2018. The clouds were located about 1,000 kilometers (600 miles) west of the California-Oregon border. Similar environmental conditions also triggered the formation of ship tracks in this part of the Pacific on August 27 and 28.

Coal ash swirls on the surface of the Dan River following one of the worst coal-ash spills in U.S. history into the river in Danville, Va., Feb. 5, 2014. The Environmental Protection Agency is moving to strengthen a rule aimed at controlling and cleaning up toxic waste from coal-fired power plants. A proposed rule announced Wednesday, May 17, 2023, would require safe management of so-called coal ash dumped in areas that currently are unregulated at the federal level.
