Chestnuts are the only low-fat nuts, with a fraction of the calories of other types of nuts. They contain just 1 gram of fat and a little less than 70 calories per 30 grams of dried or roasted nuts. The downside is they're lower in vitamins and minerals.
Launched in 1977, NASAâs two Voyager probes surveyed Jupiter and Saturn, with Voyager 2 also visiting Uranus and Neptune before heading out of the Solar System. Voyager 1 has since become the fastest and most distant man-made object in the Universe, travelling at around 61,500km/h at a distance of 17.6 billion km from the Earth. Perhaps most incredible of all, NASA is still in communication with it, despite radio signals taking 16 hours to reach it. Image Â© NASA.
For many years, the RMS Queen Elizabeth 2 was the fastest cruise ship in the world. It is capable of reaching a top speed of 32 knots per hour, and it has a cruising speed of around 28 knots. After it was retired from the cruise business, the Olympic Voyager became the fastest cruise ship.
