Earth-sized Planets

Scientists today have published new research revealing a detailed and dynamic model of the Earth's surface over the past 100 million years. For the first time, the research provides a high-resolution understanding of how today's geophysical landscapes were created and how millions of tonnes of sediment have flowed to the oceans, according to the research. Climate, tectonics and time combine to create powerful forces that craft the face of our planet. Add the gradual sculpting of the Earth's surface by rivers and what to us seems solid as rock is constantly changing. However, our understanding of this dynamic process has at best been patchy. "To predict the future, we must understand the past. But our geological models have only provided a fragmented understanding of how our planet's recent physical features formed," said lead author Tristan Salles from the University of Sydney School of Geosciences, Australia. "If you look for a continuous model of the interplay between river basi

Researchers have confirmed an exoplanet, a planet that orbits another star, using NASA's James Webb Space Telescope for the first time

NASA mission has discovered a second Earth-sized, rocky planet within the habitable zone of its star -- the range of distances where liquid water could occur on a planet's surface

The other red dwarf star, called K2-240, has two super-Earth-like planets about twice the size of our planet.
