Bursts of electromagnetic radiation that share similarities with birdsong have long been observed close to Earth. A detection farther out in space confirms a key part of the theory of their origin, but also poses questions.

Whistler-mode chorus waves have been observed in the tail region of the terrestrial magnetosphere, where the magnetic field is not dipolar so that chorus waves were not expected, and their generation mechanisms have been tested with state-of-the-art observations.

The exchange of electromagnetic and thermal energy in collisionless plasmas is an important area of study to understand many space physics processes. The authors use in-situ, high resolution measurements from the MMS mission to examine the spatiotemporal evolution of the electron thermal and electromagnetic energy landscape during an encounter with a magnetic reconnection site in the Earth’s magnetosphere.

Energetically charged particles affect polar ozone levels and have been linked to surface climate variability. This study discusses the pathway that explains the rapid connection from high altitude mesospheric ozone to surface regional climate.

Scientists studying the controversial 'running of the bulls' discover unique crowd movements they hope could prevent overcrowding deaths

How Grand Canyon-sized lunar-valleys could have been carved in mere minutes.

Unusual detection bolsters evidence that the mysterious signals can be caused by different astrophysical events.
