The NASA-funded project is asking sky gazers, storm chasers, and scientists to capture photos of sprites and other optical phenomena that flash above thunderclouds after a lightning strike.
A mega-experiment in Brazil will evaluate how tropical rain forests absorb carbon as emissions increase.
The Moon was a lot closer to Earth 2.46 billion years ago, and the shorter distance contributed to shorter days.
Infrared observations reveal that Jupiter’s upper atmosphere is much warmer than models predict. The discovery may be a clue to finding missing heat sources in other giant planets.
While past attempts to define isotopic endmembers and assign them a geodynamic significance ended in controversy, a machine-learning clustering algorithm offers a solution to this classical problem.
The Nullarbor Plain has been relatively untouched by geological forces, leaving traces of the continent’s deep past.
Scientists have traced past pathways of tectonic plates back a billion years using computer models, with intriguing results. Incorporating geologic data as a check on model output, however, has proven tricky.
Though not as damaging as extreme space weather events, showers of plasma jets hit Earth’s magnetic shield every day—yet we’re only beginning to understand their effects.
New simulations show that planets around young, massive stars may have been captured or stolen rather than homegrown.
The underwater crater, spotted serendipitously in commercial observations of seafloor sediments, is believed to have formed at roughly the same time as the famous Cretaceous-Paleogene impact event.
