This day in 2004, the Lincoln Near Earth Asteroid Research observatories in New Mexico alighted on a new and mysterious object in the sky - the asteroid soon to be known as 2004 AS1.
An amateur astronomer noticed that the object was predicted to get 40 times brighter over the next day, which would suggest that it could be on a collision course with Earth. Another researcher calculated the chance of the asteroid hitting Earth as being as high as 25%.
It didn't hit, of course. Rather than a small object very close to us, it turned out to be a big object, slightly further away from us. But, with more than 300,000 "small" asteroids near Earth, and with a 1908 asteroid strike, when a 60m asteroid hit Siberia, flattening 1800km2 of forest, it's likely that one day, one of them will.
How long do we have to wait? Experts suggest a few thousand years. In the meantime, we're passing the days with The Comet, a 1950s delight from Eddie Clark.
Throughout his life, Cash had plenty of scrapes with the law - on 7 different occasions he spent time in jail for a variety of reasons, ranging from narcotics to starting a forest fire when his truck overheated, which killed 49 of the area's 53 endangered condors.
It was probably his own outlaw-behaviour that endeared Cash so much to American prisoners. After he wrote Folsom Prison Blues, he was inundated with letters from prisoners asking him to perform for them. He did go and sing at lots of prisons, and on 13th January 1968, he famously recorded the album At Folsom Prison in the prison itself. So, let's mix a Country Breeze and dock our caps to one of the greatest country singers that ever was.
