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 ...

Please join the Lowell Center for Space Science and Technology on Thursday, January 23 at 11 a.m. for a virtual talk by Chip Manchester Abstract: Coronal Mass Ejections (CMEs) are magnetically driven ...

Referred to as a “stealth storm,” a recent coronal mass ejection went undetected until it hit Earth. Stealth coronal mass ejections are more common after the Sun transitions from the solar maximum to ...

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 ...

The Sun fired off six X-class flares in the first four days of February 2026, a burst of extreme activity spanning roughly 400,000 miles of the solar disk. That stretch covers nearly half the Sun’s ...

The Sun has hurled a massive cloud of charged gas toward Earth, a coronal mass ejection that can carry billions of tons of plasma and temporarily reshape the planet’s magnetic shield. As the ...

A coronal mass ejection could knock out power and disrupt communication on Earth Dan Falk - Science Correspondent A coronal mass ejection erupts from the sun in 2013. NASA In August of 1859, ...

Astronomers have detected a coronal mass ejection racing away from a red dwarf star about 130 light-years away. Credit: Olena Shmahalo / Callingham et al. illustration Astronomers have captured the ...

A geomagnetic storm watch is in place for July 1-2, 2025. The Northern Lights may be visible in the U.S. overnight on Tuesday and Wednesday as a coronal mass ejection travels towards Earth to cause a ...

The interstellar object dubbed 3I/ATLAS has been fascinating astronomers since its discovery in early July. The object, generally believed to be a comet, is screaming through the solar system at ...

The northern lights may be visible as far south as New York and Idaho in the coming days thanks to a geomagnetic storm roiling over Earth. These aurorae will result from the arrival of a coronal mass ...
