Pennsylvania ranks second in U. S. natural gas production, accounting for about one-fifth of U.
A NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely large ground-based optical telescopes.
Around 4. 6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this "solar nebula" underwent a huge transformation, flattening into a disk of matter that then condensed to form the central sun and orbiting planets.
Researchers at Lawrence Livermore National Laboratory (LLNL) have found that implosions designed for inertial fusion energy (IFE) can tolerate significant imperfections before performance abruptly declines, a finding that could inform the design of fuel targets for future fusion power plants.
Marine heat waves and extreme ocean acidification events are each damaging on their own. But when both stressors hit simultaneously, their individual effects can be exacerbated.
Methane is a short-lived but powerful greenhouse gas; cutting methane emissions can slow near-term warming and improve air quality by reducing harmful ground-level ozone. As ruminants digest feed, they release methane—through burps. In fact, emissions from cattle are the largest source of human...
