The XRS sensor detects X-ray energy from the sun and can detect the first signs of a solar flare. These powerful eruptions unleash a torrent of charged particles that race towards Earth.

For 50 years, these solar flare detectors have been placed on NOAA's GOES satellites. As technology improves, and old technology decays, newer detectors are launched on newer GOES satellites, ...

These are some of the strongest flares we've seen this solar cycle. ... whose GOES-16 satellite's X-ray sensor spotted the event, Tuesday's flare began at 21:58 UTC (5:58 p.m. EDT) and peaked at ...

Forecasters of space weather keep an eye on the sun to stay ahead of eruptions of solar material that have the ability to shut down power grids on Earth, disrupt aircraft routes, global communications ...

The solar flare, consisting of ... So, a dedicated ENA detector around Earth could potentially unlock their secrets, even though it would be 93 million miles (150 million kilometers) ...

The resulting solar flare was the strongest we've seen so far this cycle, and going all the way back to September 2017. The Sun's activity is definitely intensifying as we approach the peak of ...

A blazing X2.7-class solar flare erupted from sunspot AR4087 early Tuesday, hurling a scorching wave of plasma and charged particles straight at Earth. NASA/SDO.

A series of solar flares and coronal mass ejections have reached Mars, providing researchers with views of "Martian auroras," NASA said in a statement on Monday. The sun's activity levels ebb and ...

On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption — and it's heading for Earth.

The flare had a magnitude of at least X9, making it the most powerful solar eruption of the current solar cycle — surpassing a monster X8.7 magnitude blast in May.

A high-powered solar flare erupted from the sun last week, causing a major radio blackout in Europe and Asia. The eruption happened at 3:25 a.m., meaning that the sun wasn't in the Texas sky at ...

At the time, it was the second-strongest flare we had seen this solar cycle, bested only by an X8.7 on May 14. But the Sun had more radiation to expel, and it wasn't going to do so without putting ...
