These are the highest-resolution color images of any part of Saturn’s rings, to date, showing a portion of the inner-central part of the planet’s B Ring. The view is a mosaic of two images that show a region that lies between 61,300 and 65,600 miles (98,600 and 105,500 kilometers) from Saturn’s center.
The first image (Figure A, above) is a natural color composite, created using images taken with red, green and blue spectral filters. The pale tan color is generally not perceptible with the naked eye in telescope views, especially given that Saturn has a similar hue.
The material responsible for bestowing this color on the rings—which are mostly water ice and would otherwise appear white—is a matter of intense debate among ring scientists that will hopefully be settled by new in-situ observations before the end of Cassini’s mission.

One of the weirder aspects of quantum mechanics could be explained by an equally weird idea – that causation can run backwards in time as well as forwards.
What Einstein called “spooky” action at a distance could theoretically be evidence of retrocausality, which is the particle equivalent of you getting a stomach ache today thanks to tomorrow’s bad lunch.

If confirmed, the “exomoon” is likely to be about the size and mass of Neptune, and circles a planet the size of Jupiter but with 10 times the mass.The signal was detected by Nasa’s Kepler Space Telescope; astronomers now plan to carry out follow-up observations with Hubble in October. A paper about the candidate moon […]

Usually, astronomers hunt for exoplanets—planets that exist outside of our own solar system—in search of those that have the conditions to host extraterrestrial life. But sometimes, they just want to see what else is out there. That was the case when astronomers from Ohio State and Vanderbilt universities discovered the KELT-9 star system 650 light…
Fraser Cain speaks to Sarah Pearson (Space with Sarah) about dark matter and whether there could be small dark matter galaxies that we haven’t yet detected. A fascinating insight into the ongoing studies of the mysterious stuff that accounts for most of all matter in the universe.
