3 min read NASA Solar Observatory Sees Coronal Loops Flicker Before Big Flares For decades, scientists have tried in vain to accurately predict solar flares — intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA’s Solar Dynamics Observatory, one team has identified flickering loops in the solar atmosphere, or corona, that seem to signal when the Sun is about to unleash a large flare. These warning signs could help NASA and other stakeholders protect astronauts as well…

Scientists turn 3 years’ worth of solar flares into audible sound (video)
If you’re more of an auditory learner than a visual one, this timelapse video is for you. (And, well, visual learners will probably love it, too!) The European Space Agency (ESA) has released an audio-visual representation of solar activity over the last three years, pulling data from its Solar Orbiter probe, which it runs with NASA. In the video, we see blue circles popping up across the surface of the sun — and audible tones paired with each of these circles. As time progresses toward the present day, the frequency…

5 min read NASA’s LEXI Will Provide X-Ray Vision of Earth’s Magnetosphere A NASA X-ray imager is heading to the Moon as part of NASA’s Artemis campaign, where it will capture the first global images of the magnetic field that shields Earth from solar radiation. The Lunar Environment Heliospheric X-ray Imager, or LEXI, instrument is one of 10 payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center in Florida no earlier than mid-January, with Firefly Aerospace’s Blue Ghost…
Read MoreSun erupts with powerful X1.2 solar flare, causes radio blackouts (photo)
The sun started 2025 with a bang as it fired off a powerful solar flare this morning. The X-class solar flare peaked at an X.12 at 6:40 a.m. EST (1140 GMT) on Friday (Jan. 3), releasing a blast of energy from a sunspot region known as AR 3947 and triggering a radio blackout event for parts of the Southern Atlantic, Africa and parts of eastern South America. When these blackouts happen, they can result in a full or partial loss of high frequency (HF) radio signals in regions that are…

Breaking its previous record by flying just 3.8 million miles above the surface of the Sun, NASA’s Parker Solar Probe hurtled through the solar atmosphere at a blazing 430,000 miles per hour — faster than any human-made object has ever moved. A beacon tone…
Read MoreChristmas solar flares erupt from the sun. Will they trigger aurora ‘fireworks’ as we close out 2024?
In the final hours of Christmas Day, the sun fired off four solar flares within less than three hours. The biggest flare of the series, recorded at a M7.3, erupted from sunspot region AR3938 on Dec. 25 at 10:15 p,m. EST (0315 GMT on Dec. 26). Solar flares are ranked and categorized by their power on a 4-level classification scale, with M-class the second strongest to the beastly X-class at the top. According to Spaceweather.com, this was part of a group of four different flares that happened within two and…
Read MoreScientists await signal from NASA’s Parker Solar Probe after historic close sun flyby. Will it phone home?
On the heels of a NASA spacecraft’s historic close flyby of the sun on Christmas Eve, scientists on Earth have one question on their minds: Did their probe survive as an epic Christmas gift, or is it a burned up lump of coal in space? For a few days, they simply won’t know, at least not until the spacecraft — NASA’s Parker Solar Probe — phones home with a simple “status beacon” on Friday (Dec. 27) to let its science team know it’s okay. But scientists behind the spacecraft’s sun…
Read More10 most powerful solar flares of 2024
It’s been a busy year on the sun, as it officially entered the peak of its roughly 11-year cycle of activity, known as solar maximum. In 2024, the sun launched over 50 X-class solar flares — the most powerful type of solar flare — at Earth. Solar flares are categorized by the level of X-rays they produce in a specific wavelength range (1 to 8 angstroms). Solar flare classes follow a logarithmic scale, with each flare class — C, M and X — 10 times stronger than the previous one.…
Read MoreWhat time is the NASA Parker Solar Probe’s closest sun flyby ever on Christmas Eve?
A NASA spacecraft is about to give astronomers an epic early Christmas present with the closest ever flyby of the sun on Dec. 24, but if you’re wondering exactly when the ambitious solar encounter will occur, don’t worry. We’ve got you covered. The NASA spacecraft, called the Parker Solar Probe, is on course for what will be a record-setting close flyby of the sun on Christmas Eve, when it will fly through the star’s outer atmosphere at 6:53 a.m. EST (1153 GMT) and pass within 3.8 million miles (6.1 million…
