Most days, you can look up and see the Sun shining above. Even if it\u2019s hidden behind clouds, you know it\u2019s there, lighting up the sky. But while the Sun\u2019s light might be relatively constant, its surface is surprisingly active. If you hopped on NASA\u2019s Parker Solar Probe<\/a> for a closeup view of the Sun, you might see spurts of charged gas called solar flares coming off its surface, or dramatic explosions called coronal mass ejections. These events travel outward from the Sun through space, and sometimes they interact with Earth\u2019s magnetic field, causing space weather.<\/p>\n

This week, the National Oceanic and Atmospheric Administration is tracking several coronal mass ejections that could lead to a minor geomagnetic storm in Earth\u2019s atmosphere. People in Canada and the northern United States may be able to see an aurora<\/a> the evening of Sept. 9, 2026. <\/p>\n

The Conversation U.S. has compiled some articles from our archives on space weather, from the science behind how the phenomenon works to how researchers are working to better understand it \u2013 and even predict it. <\/p>\n

1. What is space weather?<\/p>\n

Solar flares and coronal mass ejections are made up of plasma<\/a>: electrically charged gas. After they explode off the Sun\u2019s surface, they travel through space and may eventually reach Earth. When they run into Earth\u2019s atmosphere, they interact with the magnetic field shrouding our planet. <\/p>\n

As explained by Yeimy J. Rivera<\/a>, Rosa Tatiana Niembro Hern\u00e1ndez<\/a> and Samuel Badman<\/a> \u2013 a team of astrophysicists at the Smithsonian Astrophysical Observatory \u2013 this collision with the magnetic field causes space weather<\/a>, or geomagnetic storms, which produce the northern lights<\/a>: the beautiful streaks of green or purple you may have had the chance to see across the sky last year. <\/p>\n

The Sun also produces the solar wind<\/a>, which is much different from a breeze you might feel on Earth. The solar wind is a stream of charged particles and magnetic field lines ejected from the Sun. Many scientists are interested in<\/a> how interactions between coronal mass ejections, the solar wind and Earth\u2019s magnetic field influence geomagnetic storms. <\/p>\n

2. Space weather and technology on Earth<\/p>\n

While space weather may look beautiful, it can also be very destructive<\/a>. These events add more particles into Earth\u2019s atmosphere, which can increase drag on satellites and cause them to fall. They also disrupt the radio waves that some satellites use to communicate with Earth. <\/p>\n

GPS is one type of technology that uses radio waves. Many facets of modern life rely on GPS \u2013 not just the map apps on your phone or in your car.<\/p>\n

\u201cFor many industries \u2013 aviation, maritime, robotics, transportation, farming, military and others \u2013 GPS positioning errors of a few meters are simply not tenable,\u201d wrote Piyush Mehta<\/a>, an aerospace engineer at West Virginia University. <\/p>\n

2025\u2019s space weather events disrupted some satellite communications and even triggered overheating alarms for power grids. But history can tell you that some space weather events are far more severe: A strong enough space weather event could do far worse<\/a> than disrupt satellite communications for a few minutes. <\/p>\n

3. Space weather throughout history<\/p>\n

Over a century ago, in 1859, a large solar flare outshone the Sun<\/a>, wrote Dagomar Degroot<\/a>, an environmental historian at Georgetown University. Telegraph lines \u2013 still very new at the time \u2013 shorted out, and that night, bright auroras lit up the sky. <\/p>\n

Since then, technology has advanced past the telegraph. Beyond satellites, a strong enough solar storm could disrupt cell networks and electrical power grids<\/a>. These systems underlie communications, transportation, utilities \u2013 even the sewer systems. <\/p>\n

\u201cFor now, one thing is certain: to protect these networks, scientists must monitor the Sun in real time,\u201d Degroot wrote. \u201cThat way, operators can reduce or reroute the electricity flowing through grids when a coronal mass ejection approaches. A little preparation may prevent a collapse.\u201d<\/p>\n

4. Studying space weather<\/p>\n

Space agencies across the globe have a suite of missions that monitor the Sun and the flares and ejections it produces. In 2025, NASA launched a few more. As Ryan French<\/a>, a solar physicist at the University of Colorado Boulder, described<\/a>, together these instruments will monitor space weather from different vantage points, to learn more about how these events are created and how they travel. <\/p>\n

In March 2025, NASA launched the Polarimeter to Unify the Corona and Heliosphere<\/a>, made up of four satellites in Earth\u2019s orbit that study how the Sun\u2019s outer surface layer creates the solar wind. <\/p>\n

Then, in September, NASA launched two more missions: the Interstellar Mapping and Acceleration Probe<\/a>, or IMAP, and the Carruthers Geocorona Observatory<\/a>. <\/p>\n

Both IMAP and Carruthers traveled out to the L1 Lagrange point<\/a>, which is a spot between Earth and the Sun where the two celestial bodies\u2019 gravitational pulls balance out. Spacecraft orbiting here get a great view of the Sun, and the gravitational balance means they don\u2019t need to constantly use fuel to stay in position. <\/p>\n

IMAP will study the solar wind and map how far particles ejected from the Sun reach into space. Carruthers, on the other hand, will turn its sights back on Earth. It will observe what happens to the outer layer of Earth\u2019s atmosphere during space weather events. <\/p>\n

NASA spacecraft track solar storms, from their eruptions on the Sun until their impact on Earth.<\/p>\n

Next year, in 2027, NASA plans to launch another complementary mission called the Sun Coronal Ejection Tracker<\/a>. This mission will watch how coronal mass ejections change as they are ejected from the Sun. <\/p>\n

All these missions will help scientists monitor and respond to space weather events \u2013 and the latter goal will only grow more important. <\/p>\n

5. Forecasting space weather events<\/p>\n

Before the end of the decade, NASA hopes to send humans back to the Moon<\/a>. And because the Moon doesn\u2019t have a magnetic field like Earth, it\u2019s especially vulnerable to space weather events<\/a>, wrote Lulu Zhao<\/a>, a space scientist at the University of Michigan. <\/p>\n

Particles in space, called cosmic radiation<\/a>, generally aren\u2019t good for the human body<\/a>. Earth\u2019s magnetic field deflects most of those particles and keeps life on Earth safe. But if particles from the Sun hit an astronaut on the lunar surface, the astronaut could be at risk for health complications like cancer. <\/p>\n

\u201cDuring a large solar energetic particle event, the radiation dosage an astronaut receives inside a spacesuit could exceed 1,000 times the dosage someone on Earth receives,\u201d wrote Zhao. \u201cThat would exceed an astronaut\u2019s recommended lifetime limit by 10 times.\u201d<\/p>\n

Zhao and her colleagues are developing a research center<\/a> that would predict space weather events. Accurate, timely predictions could protect astronauts by giving them the time they\u2019d need to get inside a shelter, as well as protect infrastructure back on Earth. <\/p>\n

Space weather research is advancing quickly, with researchers around the globe coming up with designs to help predict these events even further out. The more interconnected the world becomes, the more there will be to protect. <\/p>\n
