The sun’s outer atmosphere — the corona — has long intrigued scientists due to its extreme temperatures, violent eruptions and towering prominences — vast filaments of plasma extending out from the solar surface. Visible only during a total solar eclipse and blurred by Earth’s turbulent atmosphere, the corona has remained frustratingly elusive. Until now. Thanks to a breakthrough adaptive optics system called Cona, installed at the 1.6-meter Goode Solar Telescope (GST), operated by NJIT’s Center for Solar-Terrestrial Research (CSTR) at Big Bear Solar Observatory (BBSO) in California, scientists now have…

Incredible new images of the sun’s surface provide an unprecedented view of raging sunspots and solar activity. A new high-resolution camera system developed by the Leibniz Institute for Astrophysics Potsdam (AIP) for the Vacuum Tower Telescope (VTT), located at the Observatorio del Teide in Tenerife, reconstructed views of the sun with an 8K image resolution for the first time, according to a statement from AIP. Solar observations often face a trade-off between field of view and resolution. Large solar telescopes provide high-resolution images but cover limited areas, while smaller instruments…

Imagine being told a storm is heading your way, but you won’t know how bad the winds are or whether they’ll knock out power until just minutes before it hits. That’s the challenge scientists face when it comes to predicting solar storms. We’ve come a long way in understanding space weather. We can spot solar storm eruptions, track their speed, and estimate when they’ll arrive at Earth, sometimes with up to a day’s warning. However, one critical piece of information remains frustratingly out of reach until the last moment: the…

The sun roared to life early Tuesday (May 14), unleashing a powerful X-class solar flare from a newly emerging sunspot region AR4087. The eruption peaked at 4:25 a.m. EDT (0825 GMT), triggering strong R3-level radio blackouts across Europe, Asia and the Middle East — the sunlit side of Earth at the time — as sunspot region 2087 crackles with activity. Solar flares of this magnitude are uncommon, according to the NOAA Space Weather Prediction Center (SWPC). Solar flares are ranked by strength in five classes: A, B, C, M and…

I’ll never forget the night of May 10, 2024. I remember having dinner with a friend and talking about the potential of seeing the northern lights in Northeast Ohio, a conversation that I had never had before or even thought was possible. It sounded unlikely, but earlier that week, the possibility was brought to my attention when I wrote one of my first-ever stories highlighting space weather triggered by the sun. As a meteorologist, space weather wasn’t something I talked about often, but the more I was learning that week,…
