A man has been nicknamed the "Hardest Geezer” after he embarked on a mission to run the entire length of the continent of Africa for charity. Who is the the Hardest Geezer? Russell Cook, from Worthing in West Sussex, is no stranger to some physically brutal challenges that have earned him the label. In 2022, he was the first person to run from Asia to London and now, the 26-year-old has taken it to another level, aiming to become the first person to run the length of the African continent. Sign up to our free Indy100 weekly newsletter Project Africa began on 22 April and, if completed, will be the equivalent of Cook running 360 marathons in the space of 240 days. Now, 24 days into his journey, he has covered several hundred kilometres and even been stalked by wild cats and thieves in the process. His route began in South Africa and will see him travel north up the west coast of Africa through Namibia, Angola, the Democratic Republic of the Congo, Republic of the Congo, Cameroon, Nigeria, Benin, Togo, Ghana, Ivory Coast, Guinea, Senegal, Mauritania, Algeria before finally ending his mammoth run in Tunisia. Cook is completing the run to raise money for two charities – The Running Charity and WaterAid. At the time of writing, he has raised £13,300 of his £100,000 target. He is documenting his journey on social media, regularly updating his Twitter, Instagram and YouTube channels on his progress. In one video, Cook revealed he was “absolutely bouncing” and was looking forward to reaching a petrol garage 6km down the road where he was told they sold Cornish pasties. In a Q&A with Twitter users, he gave his advice on how others can motivate themselves. Cook explained: “Be accountable to someone or something bigger than yourself.” Have your say in our news democracy.

Scientists have been studying a “space ghost” which could be due to explode in just a few decades, changing the night sky forever – if it hasn’t already, that is. The object in question is a large star called Betelgeuse and the scientific community is divided over whether or not it’s already become a supernova. One theory states that the light from Betelgeuse takes so long to reach Earth it could mean the huge explosion has already taken place. Betelgeuse has been a supergiant red star for an estimated 40,000 years, but that could change relatively soon. Sign up to our free Indy100 weekly newsletter Michael Shara is the curator of astrophysics at the American Museum of Natural History. He told the US Sun: "Betelgeuse lies somewhere between about 450 and 550 light years from Earth." He went on to say: "Betelgeuse’s position appears to change slightly, as seen from Earth, between June and December, when the Earth is on opposite sides of its orbit around the Sun. "That tiny change in position is a direct measure of the distance to Betelgeuse." He went on to expand on the theory by saying: "Let's assume that Betelgeuse is precisely 500 light years distant. "If Betelgeuse exploded as a supernova anytime in the past 499 years, the light from that event has not yet had enough time to reach Earth…so we have no way of knowing if Betelgeuse has already blown up. "If, for example, Betelgeuse blew up in 1600 AD, we won’t know about it until the year 2100. But if it blew up on August 1, 1523, then on August 1, 2023 it will become about as bright as the full Moon. "The only naked eye supernova of the past century occurred in 1987… all astronomers would be thrilled and delighted if Betelgeuse (or another dying star) graced our night sky with a supernova in the coming decades."
