A project to produce detailed maps of all the land on Earth through laser scanning has been revealed by researchers who say action is needed now to preserve a record of the world’s cultural, environmental and geological treasures.
In the search for the earliest life on Earth, it can be hard to tell whether you're looking at an actual fossil, or crinkles in the rock itself. Such doubts have long shadowed the 1980s discovery of 3.5 billion-year-old fossils in the Australian desert. Now, scientists think they have finally put the matter to bed.
Earth seems like the perfect hub for life because it's the only planet known so far to host it — but new research suggests that other planets could have oceans that are even more hospitable, offering life that is more varied than we know it.
Jupiter, the Solar System’s largest planet, may have been smacked head-on by an embryonic planet 10 times Earth’s mass not long after being formed, a monumental crash with apparent lasting effects on the Jovian core, scientists said.
Temperatures hit a record 69.8 degrees Fahrenheit (21 degrees Celsius) in Alert, the northernmost permanently inhabited spot on the planet less than 600 miles (955 kilometers) from the North Pole, the Canadian meteorology service said Tuesday.
