The sun has spat out two clouds of plasma in the past two days, which might trigger beautiful aurora displays observable as far south as New York later this week.
See our amazing collection of stories and features about the increasingly important topic of space weather (aka solar storms).
A surprise solar storm bashed Earth on Aug. 7 and 8, triggering an appearance of the mysterious glowing phenomenon called STEVE.
NOAA reported that a "moderate" solar storm struck Earth over the weekend, and another once could hit today.
Earth was zapped by a solar storm on Sunday (Aug. 7) and the activity generated enormous auroras, or northern lights, across a swath of the planet.
Satellites and space debris objects in low Earth orbit could get lost for weeks if a major solar storm hit Earth, increasing the risk of collisions and rendering the space around Earth unsafe.
Solar wind is blowing from the sun with unusual intensity these days, and space weather forecasters think it might make polar lights brighter.
Reference Earth is no stranger to the sun's wrath. From solar flares to coronal mass ejections, we take a look at some of the worst solar storms in history.
A European satellite that has been scrambling to escape premature death in Earth's atmosphere due to bad space weather has narrowly avoided a collision with a random piece of space junk.
There is a layer of Earth's atmosphere that we know almost nothing about. NASA wants to change that.
It's clear that space weather can cause blackouts, but scientists are still working to predict extreme events and forecast their potentially devastating effects.
SpaceX's Starlink satellites are providing data to NOAA to help improve space weather forecasts as spacecraft operators struggle with unexpected effects of frequent solar eruptions.
Reference Space weather refers to conditions in the region of space that is affected by the sun. It is tricky to predict and can wreak havoc on the technological world.
A sunspot nearly triple the size of Earth is within firing range of our planet and may send out medium-class flares in the near future.
Reference Solar wind is composed of charged particles and the sun's magnetic field and is continually released from our star. Explore the phenomenon in more detail here.
Auroras don't just exist on Earth. Here's what we know about auroras on other planets in the solar system.
Reference Sunspots are cooler, planet-size regions of strong magnetic fields on the surface of the sun. Explore sunspots in more detail with our comprehensive guide.
Reference Coronal mass ejections (CMEs) are colossal expulsions of plasma and magnetic field from the sun's corona. Explore CMEs in more detail here in our guide.
Reference The Carrington Event took place in September 1859 and is one of history's largest solar storms. Events like this can wreak havoc on our technological world.
