Earth 'to be wiped out' by supernova explosion, meanwhile...
The star, called T Pyxidis, is set to self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT.

Although the star is thought to be around 3,260 light-years away ? a fairly short distance in galactic terms ? the blast from the thermonuclear explosion could strip away the Earth's ozone layer, the scientists said.


Robin Scagell, vice-president of the UK's Society for Popular Astronomy, said: "The star may certainly became a supernova soon ? but soon could still be a long way off so don't have nightmares."

uh...."Don't Panic!"?...

I saw that last night. I didn't see that the article had all the specifics, but I think it's safe to say that a blast wave would propagate much, much slower than the speed of light. Add to that the 3260 light years distance, we're safe, right? that I think about it, we're looking at the star as it was 3260 years ago, right? Dang, we might already be dead!

In reply to: Yeah...


I wonder if rates of cancer or similar diseases brought on by radiation may be associated with the limits of our ozone layer to keep out "excessive" radiation...

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
