Quasars, or quasi-stellar objects, are one of the brightest and most active types of supermassive black holes that feed on gas at the center of a distant galaxy. 3C 273 is the first quasar ever to be identified. It is located in the constellation of Virgo. An international group of scientists has published new observations

An explanation for how lightning moves to the ground in successive luminous stages separated by “dark” intervals of many microseconds is an open question in lightning physics. The structure of the black column that connects the streamer step and the cloud, which can be kilometers long, is electrically conducting but has a very weak sustaining

Tracking mass through harsh environments requires surrogate particles that withstand the event and endure until sampling. Scientists have previously reported on the survivability of ruggedized particulate tracers during explosions. In a new study by Pacific Northwest National Laboratory (PNNL), scientists have created rugged tracer particles that could survive and thrive in extreme conditions. Fluorescent dyes

Many current and exciting scientific questions that astronomers are trying to answer require them to collect large samples of different cosmic events. As a result, modern astronomical observatories have become relentless data-generating machines that throw thousands of alerts and images at astronomers every night. Using a machine learning algorithm, astronomers from the Zwicky Transient Facility
