We’ll let Veritasium explain..

In our eagerness to identity the Universe’s occult phenomena of dark energy and dark matter, we often forget that most of its better defined particles also seem to be MIA.
Relax. We now have our first solid piece of evidence that this matter has been hiding in the delicate threads of cosmic webbing bridging neighbouring galaxies, right where the models predicted.

“In 2010, Erik Verlinde surprised the world with a completely new theory of gravity. According to Verlinde, gravity is not a fundamental force of nature, but an emergent phenomenon. In the same way that temperature arises from the movement of microscopic particles, gravity emerges from the changes of fundamental bits of information, stored in the very structure of spacetime.”

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.
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…
