Not one, not two but three huge asteroids are paying us a holiday visit, and are due to speed relatively near the Earth on Christmas Day. Relative to distances in the universe that is, so there is no reason to panic.The three asteroids are named 2022 YL1, 2013 YA14 and 2022 TE14, and are estimated to measure between 124 and 278 feet, between 167 and 360 feet and between 312 and 689 feet in diameter, respectively.Therefore, 2022 YL1 is around the same size as the wingspan of a Boeing 777, 2013 YA14 is similar in scale to an American football…

A gargantuan asteroid measuring between 1,000 and 2,430 feet in diameter, is due to fly past Earth on November 1.The asteroid, named 2022 RM4, is traveling at speeds of roughly 52,500 miles per hour, and is expected to sail past the Earth at a distance of 1,427,801 miles.In comparison, the moon is only 238,900 miles away, and our nearest planetary neighbor, Venus, is 38 million miles away at its closest point. The One World Trade Center building measures 1,792 feet tall at its tip.Asteroids are small rocky objects that also orbit the Sun. NASA estimates there are 1,113,527 asteroids present…

Generation Z – those born after 1995 – overwhelmingly believe that climate change is being caused by humans and activities like the burning of fossil fuels, deforestation and waste. But only a third understand how livestock and meat consumption are contributing to emissions, a new study by the University of Sydney and Curtin University researchers has revealed.The researchers say this result comes despite estimates that over a quarter of the world’s emissions are linked to meat and livestock production, calling for greater awareness among young people.Led by Dr Diana Bogueva in the Centre for Advanced Food Engineering and School of…

A large proportion of fish meant for human consumption may contain microplastics, scientists have found, with one expert saying that the decision whether to eat fish or not was a “personal choice.”According to a paper published in the journal Marine Pollution Bulletin, three quarters of fish caught off the coast of southern New Zealand contained some degree of microplastic in their tissues.Microplastics are tiny fragments of plastic defined as being less than 0.2 inches in diameter.”75% of fish that I sampled had ingested microplastic. I sampled fish over a two-year period, throughout all seasons, along the south-east coastline of southern…

Deep sea mining has now been approved to be trialed at the bottom of the Pacific Ocean, in a controversial move.The Metals Company, a deep sea mining company, has now been permitted to test its mining machinery in the Pacific by the International Seabed Authority for the first time since the 1970s. However, some Pacific Island nations are not fans of this move.Deep sea mining involves harvesting minerals from the seabed of the deep ocean, below 650 feet, as opposed to underground on land.The most sought after minerals on the seafloor include polymetallic nodules, polymetallic sulfides and cobalt-rich ferromanganese crusts,…
