Storms of this severity can impact satellites, astronauts, and some commercial flights.
Scientists observed the most active solar region in decades for a record-breaking 94 days.
Scientists suspect that smaller "tornadoes" of solar plasma and magnetic field may be escaping our detection.
“The Sun is slowly waking up.”
A record-breakingly sharp image of a solar flare allowed astronomers to get a closer look into the Sun's mysterious coronal loops.
The explosion created a 250,000-mile-long, boiling trench of hot plasma and debris in the star’s outer atmosphere.
Images from the Parker Solar Probe’s record-setting pass by the Sun last year are finally available.
It sort of looks like a honeycomb of hot gas, or a hazelnut croquant.
Earth may experience another solar storm—and more auroras—in early June as the hyperactive sunspot cluster rotates back into view.
A recent solar storm triggered auroras around the world, but as millions watched this celestial display, its effects were also seen at the bottom of the ocean.
SpaceX's Elon Musk said the company's Starlink satellites were "under a lot of pressure" from the incoming radiation.
“We have a very rare event on our hands," according to space weather forecasters.
A batch of strong solar flares has appeared on the Sun over the past few days, prompting officials to issue a severe geomagnetic storm watch.
This historically large sunspot, now 15 times wider than Earth, rivals the one linked to the colossal solar storm of 1859.
The Parker Solar Probe flew through a coronal mass ejection in 2021, finding clues that are helping to unravel the mystery of space weather.
A solar superstorm could cause a rail disaster, scientists warn.
Both solar flares were X-class events, the most intense and energetic storms the Sun can emit.
A geomagnetic solar storm is forecast to make the aurora borealis visible in much of the lower 48 on Thursday night. Here's where to look.
Six spikes in Earth’s radiation levels, recorded in tree rings, may represent an unknown extreme astrophysical event.
The spacecraft survived the encounter and even managed to capture value data about our host star.
