The most fundamental outdoor skill is also often one of the most misunderstood. Learn these five campfires and you'll be able to cook food, scare off wild animals, stay warm or just have a bonfire on the beach. They're simple, but everyone can probably learn something here.


Ever wondered what a dead star looks like? Then have a gander at the image above -- you're looking at "Kepler's Supernova". First spotted 410 years ago today, it's the most recent supernova to have been observed without sky-gazing equipment within our own galaxy.


I never imagined I was going to see something like this: A video of a star bursting in space, illuminating the interstellar dust around it at the speed of light. This is not a computer simulation. It's an actual timelapse video taken over four years by the Hubble -- and scientists don't know its origin yet.


This is a grain of interstellar dust. To get one of these, your best bet is to get into a spaceship for a couple of hundred years and get close enough to a red giant star, near its atmosphere. That's where they're formed and ejected into space. Or, like NASA, you can create a machine to make one from scratch -- for the first time ever.


NASA has created the first ever map of radioactive material in a supernova remnant, revealing one of the biggest mysteries in the universe: How stars blow up in these explosions, sowing the universe with heavy elements like iron, titanium or gold.


Hubble has captured "a striking new image throwing off narrow streams of gas from its poles." Looks like the wings of an angel or a scene from Star Trek, with the Enterprise about to enter the frame.


And with "just" I mean 11.4 million years ago, even while Steve Fossey just detected this bright and rare Type Ia supernova using a 'modest telescope in an unlikely spot: foggy north London.' Scientists say that it will be visible in the sky soon, as it brightens up. Here you can see the supernova appearing in the sky, in a before an after image of M82, the Cigar Galaxy.


The Hubble space telescope has captured "a lidless purple eye, staring back at us through space" -- a star 20,000 light-years away from us that is ready to explode at any time now, according to NASA.


Astronomers at the Atacama Large Millimeter/submillimeter Array (ALMA) observatory have found something really strange for the very first time: a strange tridimensional spiral structure inside of a dying star, one that is just like our very own Sun. Is this the last thing that the human race will ever see?
