Super Supernova


Another star’s just gone up.

Blown itself into a thousand million smithereens.

I say just, but it happened years ago. Hundreds, possibly thousands of years ago, but because it’s so far away the light from the explosion is only now reaching us.

The supernova straddles two constellations from our point of view, Tucana and Indus, and we can’t see it with our own eyes, even in its exploded state – that shows you how far away it is.

Mind you, I have to position a piece of paper at a certain angle to be able to see what’s written on that, and that’s in my hands, so I’d have no chance. Eagle-eyed observers may see a faint twinkle if they looked long enough in that general direction, but it’s better to use the more powerful telescopic equipment – saves eye strain.

According to Space.com, if the star were a mere 8.6 light years away from us, like Sirius for example (which just happens to be the brightest star in our sky), it would be shining as bright as our Sun now.

Scientists think that the supernova could be being powered by a magnetar, a kind of star that is made up entirely of neutrons, which can be created when a star explodes. The magnetic forces of this swirling mass of neutrons creates enough magnetic energy that will heat up the gases created when the star exploded causing them to glow even brighter.

So, in effect, the star creates its own energy source to make it glow brighter when it explodes. Sounds like a paradox to me, but I’m not a scientist. And I like paradoxes.

That said, Betelgeuse, the star in the Orion constellation, the star that may very soon itself go supernova, is hard at work creating heavier and heavier elements in its core, elements that will one day be used to create new stars and perhaps a magnetar of its own.

I’ve written posts before about us having two ‘suns’ when Betelgeuse explodes, causing night to become as bright as day, and this may explain how that would be possible.

It’s amazing, though, that at the end of a star’s life, new stars are created from its very demise.

The Universe. As baffling as it is to mere mortals such as I, it’s so full of wonder and awe that you can’t help to be mesmerised by the magic of it all. Well, I can’t, but I’m easily mesmerised…

    Yes, it’ll be interesting to see old beteljuice pop its cork, but we won’t be around when it happens! 🙂

    Jokes aside, Betelgeuse is one big old star and provides plenty of food for thought as it runs out of fuel.

    Be thankful it’s not closer – the amount of radiation it’ll produce will still be notable even at this distance!

    640 Light years may seem like a great distance, but in astronomical terms it’s our neighbour, however it is far enough away that the emissions it will produce will be largely stopped by our magnetosphere and atmosphere.

    It may make it necessary to evacuate any space stations in orbit and the satellites MIGHT take a hit, but they get worse off our own star’s Coronal Mass Ejections and keep running so no worries! 🙂

    My one regret is that we won’t be around to see it. 😦

    God Bless!

      640 Light Years isn’t a journey I’d fancy on a crowded train, Prenin, neighbour or not!
      And you never know, we may get to see it in a different incarnation.

    Interesting TL…Thanks for the astronomy course 🙂 Please don’t YOU go supernova on us! We need you around a while longer and what would the mansion do without you? VK

      I’ll try not to, VK, although one of those little voices in the back of my mind is whispering that the Mansion may go supernova first…

    My mind is boggling now at the immensity of it all!

      That’s half the fun, Elaine! You just grasp the enormity of it all, and then you realise that that grasp is the equivalent of the tiniest speck… if that! I love my mind being boggled with matters such as this.

      Thank you, Sherri!
      It’s remarkable what’s out there.

    […] next post was Super Supernova, where I referred to the light reaching us from a distant star that had gone supernova, and also […]
