NASA confirms liquid water flows on present-day Mars

NASA confirms liquid water flows on present-day Mars

Analysis of data gathered by NASA’s Mars Reconnaissance Orbiter found strong evidence for the existence of liquid water on the surface of Mars (1). It is no mystery that there was once water on Mars. Its impressive array of canyons and riverbeds, including the Valles Marineris, the largest known canyon...

Oversized nuclear black hole befuddles host galaxy’s evolutionary history

Oversized nuclear black hole befuddles host galaxy’s evolutionary history

Researchers at Keele University have found a supermassive nuclear black hole that exceeds the size limitations of its host galaxy and has now been proven to be the source of many of the galaxy’s anomalies.  Among these is the fact that such a large black hole exists in an apparently...

 
 

Robots assist in mapping a submarine canyon

Robots assist in mapping a submarine canyon

A combination of novel robot technology and ship-based measurements has allowed the National Oceanographic Centre (NOC) to create a 3D map of the only deep-water conservation zone in England (1). The image depicting Whittard Canyon in the Bay of Biscay constitutes the first 3D picture of a submarine canyon habitat...
