Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's accretion disk, where infa.....»»
What the unique shape of the human heart tells us about our evolution

Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Mapping Martian meteorites: Tracing origins on the red planet
Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They've traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. T.....»»
Ocean salinity affects Earth"s climate—how about on exoplanets?
There's a link between Earth's ocean salinity and its climate. Salinity can have a dramatic effect on the climate of any Earth-like planet orbiting a sun-like star. But what about exoplanets around M-dwarfs?.....»»

International team sequence the world"s largest animal genome: Data help explain tetrapod evolution
Join us as we travel back in time. We have arrived in the Devonian period, some 420 to 360 million years ago. In a shallow area near the water's edge, something happened that would forever change life on our planet: a fish from the class of lobe-finn.....»»
Rocks collected on Mars hold key to water and perhaps life on the planet: Researchers urge bringing them back to Earth
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the red planet and even contain evidence for past life on Mars......»»
Video: Arctic Weather Satellite advancing weather forecasting in a changing climate
