The latest book marks our third effort to review available literature regarding the role of nutrition in astronaut health. In 2009, we reviewed the existing knowledge and history of human nutrition for spaceflight, with a key goal of identifying additional data that would be required before NASA could confidently reduce the risk of an inadequate […]
One of the largest of Jupiter’s nearly 100 recognized moons, Europa is covered with a global ice cap. But beneath that crust of ice, researchers have found an ocean of liquid water, estimated to have about twice the volume of all of Earth’s oceans combined. This vast amount of liquid water is of particular interest […]

James Webb Space Telescope sees lonely supermassive black hole-powered quasars in the early universe
Using the James Webb Space Telescope, astronomers have peered back 13 billion years to discover surprisingly lonely supermassive black hole-powered quasars. The James Webb Space Telescope’s (JWST) observations are confusing because isolated black holes should struggle to gather enough mass to reach supermassive status, especially just a few hundred million years after the Big Bang. […]
NASA, ESA, CSA, STScI, Webb ERO In its short existence, the James Webb Space Telescope (JWST) has transformed our understanding of the universe. It has peered at planets, stars, galaxies and black holes, casting its eye over a cornucopia of celestial treats. It can seem like JWST arrived out of nowhere, but the telescope has […]
