Engineers at the NASA/CalTech operated Jet Propoulsion Laboratory (JPL) have found an ingenious way to entend the life of the aging spacecraft – the only one to visit the ice giants, Uranus and Neptune and is now sending back vital data about the region beyond the Heliosphere – the region where the Sun’s magnetic field… Read More »

Researchers have concluded that the molten rock and cooled volcanic glass present on the surface of Lava-Ocean Planets is unlikely to be the cause of their brightness, some of which have an albedo higher than Earth. This is intriguing, these lava-Ocean worlds are similar in size to Earth but whizz around their host star so… Read More »
