The Sun looks like a steady lamp, but its surface is a churning mass of superheated gas threaded with powerful magnetic fields. When those fields snap and reconnect, they can release an enormous burst ...

A powerful solar flare erupted from the sun on November 14, 2025, causing radio blackouts across parts of Africa. This X4-class flare, the second-strongest of the year, originated from a highly active ...

While many studies have compared the magnetic properties of confined and eruptive solar flares, few have considered the thermodynamic properties of confined flares and even fewer in comparison to ...

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

At a distance of just over four light years, Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf star. Its flare activity has been well-known to astronomers using ...

A recent CU Boulder study suggests that confined flares are more efficient at heating plasma and producing ionizing radiation than comparable eruptive flares While many studies have compared the ...
