METEORSOver the entire surface of the Earth, at least 50,000 meteors are visible every year. But it's a rare thing to capture their flight. Videos recorded by everyday Russians of an asteroid airburst in 2013 created an internet sensation. It was the first asteroid impact ever recorded - from entry to impact. What can science learn from YouTube? Enter 'forensic astronomy'. Several teams around the world used the videos to figure out the trajectory, origin, and destructive power of the meteorite - and what it could mean for future hazards to public safety.SEA LEVEL RISEIt's barely noticeable, but waters are lapping at our shores a little higher every year. Catalyst goes on an investigation to uncover one of the great unknowns of the climate debate: sea level rise. We explore what is currently making our oceans expand, and how this will change over time. And will the West Antarctic ice sheet collapse, unleashing five metre high sea level rises across the globe?HOUSE FIREHow much time would you have to get out of your house if it was burning? At the CSIRO fire testing facility in Sydney, Catalyst sets a typical boy's bedroom alight. The speed with which the fire destroys the room is alarming. Since the 1950s, house layout and furnishings have changed remarkably, possibly improving aesthetics but providing fuel and the perfect environment for house fires. No one can afford to be complacent about house fires. A must watch! PRODUCTION DETAILS:Ingrid Arnott is series producer for ABC |
