back to article Exploding 'laptop batt' IN SPAAACE! Speeding lithium spaffed by nova

For the first time, astronomers have detected lithium spread across space at high speed by an exploding star. The eggheads hope this discovery will solve one of the chemical riddles of the universe. Using telescopes in Chile, an Italian team focused on Nova Centauri 2013, a nova whose light reached Earth two years ago. It is …

    So....

    When those laptop batteries explode, they are just functioning as they were supposed to?

    I can see a clever lawyer using this on court...

      Nope the explosion creates Lithium - so unless you have more battery after it explodes than before .....

        No, the explosion spreads the lithium, Lithium is a normal product of late life star fusion.

        As a stars hydrogen is consumed it is not enough to sustain the star, gravitational collapse leads to high core pressure and temperature allowing higher order fusion to take place. If the star is massive enough this can go as far as creating iron. (The latter stages of this happen in the final minutes before the star explodes as only stars massive enough to end as supernovae take fusion that far.)

        Fusion into heavier elements is endothermic so cannot sustain the star, these elements are only created in a supernova explosion itself.

    Bah!

    Are those English billions or American?

    Typical Register imprecision.

      "Are those English billions or American?"

      A quick assessment of current usage of the word "billion" in British news sites and government pronouncements suggests short-form billion is almost universal.

      Except, perhaps, in El Reg comments. I suspect I could find comments here still arguing about decimalization of the pound, too. ;)

      The British billion hasn't been used since the 1975, thanks (or not) to Denis Healey.

    So, how much lithium then ?

    A billionth of the mass of our Sun is what ? Instead of "2,000 billion billion billion kilograms", we end up with 2,000 billion billion kilograms, or 2 billion billion tons, or 4.7619e+17 KiloJubs.

    Any way you look at it, it's one heck of a lot of batteries.

      That's really 2000 Exakilograms or 2 trillion billion kilograms or 2 octillion milligrams.

      What exactly is wrong with saying 2 X 10E+24 grams

        What exactly is wrong with saying 2 X 10E+24 grams

        'round these parts, the "E" notation implies base-10, so what's wrong is that it should just be "2E+24", or even more concisely and readably, "2e24". But perhaps notation is more verbose in your neck of the woods.

    Slipped a couple of digits again...

    "1.24 million MPH – or 0.185309 per cent" FTFY as warp 1 is about 1080 million KPH.

    Since Lithium is so uncommon in normal stellar processes this is a very important find... well done!
