back to article Astroboffins map engine of a solar flare: Magnetic mega-fields and Earth-dwarfing blankets of electric current

One of our Sun's large, recent solar flares was formed from the release of 10 to 100 billion trillion joules per second of magnetic energy through gigantic sheets of near-light-speed electrons, scientists say. Those sheets of electric current stretched more than 40,000 kilometres across, or more than three times the diameter …

    10 to 100 billion trillion joules per second

    Quite a lot of Watts, then?

      Yeah, 10^23 W or 100 sextillion watts.

          Or a well done Welsh Rarebit in about 1 nanosecond.

          For everyone in Wales?

            277 thousand kWH for one rarebit seems beyond "well done"...

            [Edit] Ah, you meant ~3M rarebits...

              It's a self assembly rarebit: here are some ions and your instructions, written in Martian; assemble the meal yourself using standard Martian atomic-force telekinesis. (Will require customer supplied electrons - not included. May also require additional Guinness, Worcestershire sauce, mustard, butter, cheese, bread and grilling.)

            I refuse to accept the cancel culture that insists on calling Welsh rabbit Welsh rarebit.

              Mencken was told Welsh Rabbit contains no rabbit. He replied that toad-in-the-hole contains no toad
