Space Weather

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.

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.

Holes in the sun can beam out solar material at 500 miles per second.

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.

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.

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.

Auroras don't just exist on Earth. Here's what we know about auroras on other planets in the solar system.

A trio of moderate flares blasted off from the sun on Thursday, and there might be more in store.
