At 9:20 am on 15 February 2013, the people of the industrial town Chelyabinsk in Russia were starting their mornings when a light streaked across the sky. Bright enough to outshine the Sun, people ran to windows to see the trail it left in the sky. A few minutes later, a boom swept through the town, shattering windows, bringing down walls, and knocking people to the ground.
That shocking sound was a meteor exploding overhead, but it wasn't just the noise. Fragments of rock were blasted across the landscape by the blast, falling down on the snow like rain.
Videos from dashcams and CCTV cameras soon appeared on news channels around the world, sending meteorite hunters and researchers flocking to the town. Among those who arrived after the airblast was a young Ph.D. student just getting started in her journalistic career - me.
I'd been asked to present a documentary about the event with the rather dramatic title of Meteor Strike! Fireball from Space, which was how a film crew and I found ourselves knee-deep in snow during the Russian winter, three weeks following the explosion. However, it was the very snow-freezing my toes that made Chelyabinsk the perfect place for a meteorite hunt. When the rocks fell onto untouched snow, the heat they picked up from their journey through the atmosphere melted a clear, obvious hole. Find a hole, dig to the bottom and there's a good chance you'll find a meteorite.
The area had been picked over by the time we arrived, but our director did manage to find a 1cm wide pebble. It was pure black, covered in a fusion crust created by the heat of entry melting the surface. There's something magical about holding a freshly found meteorite in your hand. This was a fragment left over from the birth of the Solar System.
It had been in space for billions of years until just a few weeks ago. And by this point, there was even a pretty good idea of where it had been.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
