The X5.1-class eruption from sunspot AR4274 is this year's most powerful solar flare and Earth is in the firing line.

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at ...

The back-to-back eruptions caused radio blackouts across two hemispheres as the active sunspots turn to face Earth.

The sun has a bone to pick with Earth — and it’s not done yet. A colossal solar storm just zapped the daylight side of the planet, causing global blackouts and knocking out radio signals across Europe ...

When planetary rings are mentioned, the image of Saturn immediately comes to mind. However, this celestial feature is not exclusive to gas giants and appears in much more unexpected places in ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show. By Katherine Kornei If our species manages to hang on ...

Scientists caught a massive and extremely powerful X-class solar flare being spat out from the sun on Friday (March 28), just before the stellar eruption triggered a radio blackout across two ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years from ...

As the third confirmed interstellar object to pass through our solar system, 3I/ATLAS is prime for new discoveries. It was ...

The birth of a new solar system may have been caught on camera. About 1,400 light-years from Earth sits a young sunlike star surrounded by cooling gas and teensy silicate minerals. These mineral ...
