Astronomers Capture Sharpest-Ever Solar Flare Images with NSF’s DKIST Telescope
Astronomers have achieved a major breakthrough by capturing the sharpest images of a solar flare ever recorded, using the National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST). Observed at the hydrogen-alpha wavelength during the decay of an X1.3-class solar flare, the images unveiled hundreds of ultra-fine coronal loops averagin...

Why Are Sunsets So Pretty In Winter? There's A Simple Explanation
If you live in the southern hemisphere and have been stopped in your tracks by a recent sunset, you may have noticed they seem more vibrant lately. The colours are brighter and bolder, and they linger longer in the sky.

Massive X1.1-class Solar Flare Causes Radio Blackouts Across America
A strong X1.1-class solar flare erupted from sunspot AR4046 on March 28, 2025. The flare caused major radio blackouts in North and South America, affecting high-frequency communications. A coronal mass ejection (CME) followed the flare but is not expected to hit Earth. More solar activity is anticipated from sunspot AR4046 and AR4048, with a 15% ch...

NASA’s EZIE Satellites Begin Mission to Study Auroral Electrojets and Space Weather
NASA’s Electrojet Zeeman Imaging Explorer (EZIE) mission has been launched aboard a SpaceX Falcon 9 from Vandenberg Space Force Base. The trio of small satellites will map auroral electrojets, powerful currents in Earth’s atmosphere linked to solar storms. Their data will enhance space weather prediction models and help understand planetary mag...

AMS Data Reveals Charged Particle Variations in Heliosphere Over Solar Cycle
Researchers analysing AMS data aboard the ISS have identified variations in charged particles within the heliosphere over an 11-year solar cycle. Shifts in the heliospheric magnetic field impact antiproton behaviour and cosmic nuclei fluxes, revealing correlations between solar modulation and cosmic ray movement. AMS measurements provide insights i...
