OVERLOOKED F-BOY STARS COULD HARBOUR LIFE illustration of yellow white star An often-overlooked type of star could have planets in the habitable zone and harbour life, according to new research. Stars are categorised by surface temperature as well as other physical factors such as mass, luminosity and radius. Astronomers identify surface temperature variation in stars by dividing them up into 7 groups, identified by different letters. […] Read more... ANTARCTIC PENINSULA HAS BECOME 10 TIMES GREENER IN JUST 40 YEARS A photograph of the side of a hill covered in green moss. In the background is a grey ocean with chunks of ice floating in it. Antarctica, known as the White Continent, is going green. Scientists from the British Antarctic Survey analysed satellite data of the Antarctic Peninsula and found that vegetation cover has increased more than 10-fold over the past 40 years. Vegetation took up an area of less than 1km2 in 1986, but this grew to almost 12km2 by […] Read more... IS EARTH’S UNIQUE PLATE TECTONICS THE REASON LIFE FORMED HERE? Plate tectonics researcher Alan Collins Professor Alan Collins, the Douglas Mawson Professor of Earth Sciences at The University of Adelaide, is building a dynamic map of the Earth’s plate tectonics spanning nearly a third of our planet’s existence, from 1800 to 500 million years ago. The map might reveal critical mineral locations, but Collins also believes tectonics are part of […] Read more... Don't keep Cosmos to yourself - click here to share this newsletter with a friend!
