Cassini to Make Final Flybys of 2 Icy Saturn Moons

The plumes of Enceladus as seen by Cassini in 2009. NASA/JPL/SPACE SCIENCE INSTITUTE For the next six months, NASA’s Saturn-orbiting Cassini spacecraft will get its final look at two icy moons — one famous and one not so well-known. It will fly by the erupting moon Enceladus three times, checking out its plumes in the best […]

Data from NASA’s New Horizons Hints at Underground Ocean on Pluto

Four images from New Horizons’ Long Range Reconnaissance Imager were combined with color data from the Ralph instrument to create this enhanced-color global view of Pluto. Image: SwRI/JHUAPL/NASA Scientists believe that the ice flows and water ice mountains revealed by New Horizons help support the idea that an interior ocean may be driving geologic activity […]

Mystery Solved? Why Pluto’s Big Moon Charon Has a Red Pole

The red pole on Pluto's largest moon could be remnants of the dwarf planet's escaped atmosphere. This image was taken by NASA's New Horizons spacecraft on July 13, 2015 during its historic flyby. Credit: NASA-JHUAPL-SwRI Enlarge The dark red pole on Pluto's largest moon Charon may be some of the dwarf planet's own siphoned-off atmosphere.

The so-called failed stars, which are difficult to detect and also remain hard to classify, are too massive to be planets but physicists from […]

Dense star clusters shown to be binary black hole factories

Credit: NASA Enlarge The coalescence of two black holes—a very violent and exotic event—is one of the most sought-after observations of modern astronomy. But, as these mergers emit no light of any kind, finding such elusive events has been impossible so far. Colliding black holes do, however, release a phenomenal amount of energy as gravitational waves. […]
