Solar flares can generate a variety of problems, as one of the world’s leading experts on the sun explains.

The Sun provides nearly all Earth's energy, but it's also a hazard. Our nearby star occasionally emits a tremendous energy jet that knocks down technology. Here's the worrisome part: Earth hasn't been hit by powerful space weather since humanity started relying on technology. As the Sun nears peak activity, some worry about potential threats. Space weather specialists claim we've had a couple of low-level events recently. Interesting Engineering got down with heliophysics Gregory D. Fleishman, a specialist on the Sun's outer layers, to learn more. Length and clarity were edited. What's space weather? Gregory D. Fleishman: It discusses interplanetary conditions that affect Earth's infrastructure, technology, and life. Space weather has many components. The solar wind is t...

A powerful solar flare is headed toward Earth, which could cause radio blackouts.

A space weather physicist tweeted that the Sun just let out a huge solar flare, which could cause radio blackouts in many parts of the world. Now that the Sun is in an active part of its 11-year cycle, more things like this are likely to happen. Earlier this week, astronomers were keeping an eye on sunspot AR3038 to see if it was going to do anything. But AR3058 is a new region that erupted early and has a chance of producing an X-class flare. How bad can flares from the sun get? Solar flares are powerful, localized explosions of electromagnetic energy on the sun's surface. Solar flares are put into classes A, B, C, M, and X based on how strong they are. Class A flares are the weakest, while class X flares are the strongest. When these flares go off, they release intense bursts o...
