Beneath the Earth, ancient ocean floor likely surrounds the core
Through global-scale seismic imaging of Earth's interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results published in Science Advances.
Seen only in isolated patches previously, the latest data suggests this layer of ancient ocean floor may cover the core-mantle boundary. Su Juice: running on solar power in the dark
Welcome to Jupiter space: to one side looms the vast cloudy face of the largest planet in our Solar System; in the other appears a shrunken Sun, like a spotlight in the sky, with just 3% of the illumination from Earth orbit arriving here. This basic fact presented a major challenge to those planning ESA’s Jupiter Icy Moons Explorer, Juice, mission: how to make solar power work in such a gloomy environment, located an average 778 million km away from our parent star?
