A recent CU Boulder study suggests that confined flares are more efficient at heating plasma and producing ionizing radiation than comparable eruptive flares While many studies have compared the ...

A coronal mass ejection (CME) struck Earth last night. At first, it appeared weak and failed to trigger an immediate magnetic storm. But like they say in the iconic fable "The Hare and the Tortoise," ...

Magnetic recycling: when a CME does not stay gone To understand why the solar wind can loop back, I have to start with the CME that launched it. Coronal mass ejections are huge eruptions of plasma and ...

A plume of solar plasma flung out from the surface of the sun might be about to spark auroras as far south as Illinois and Oregon. The coronal mass ejection (CME) was released from sunspot AR3842 at ...

An SwRI-led study of the Sun confirms decades-old theoretical models about solar magnetic reconnection. Measurements from NASA’s Solar Parker Probe helped fill crucial gaps in the data about processes ...

A coronal mass ejection (CME) is a large-scale eruptive solar phenomenon in which magnetized plasma from the Sun’s corona is expelled into interplanetary space, typically associated with magnetic ...

Rain is a common phenomenon on Earth. There is a similar phenomenon on the Sun, called coronal rain. It is related to the coronal heating and magnetic field, and plays a fundamental role in the mass ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A twisting, whirling streamer of plasma escaping the sun in the aftermath of a coronal mass ejection (CME) has been captured on video by the European Space Agency's Solar Orbiter, and could provide ...
