Fascinating look inside Saturn’s Rings

September 7, 2017

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.

Two Galaxies, One Photo

Since it left Earth on April 24, 1990, the Hubble telescope has delivered again and again stunning snapshots of the vast universe around us, and kept us in awe of the marvels of space. To mark the 27th anniversary of the telescope’s launch, NASA has released this epic image of two galaxies captured in one…

Some Sunday Joy for SpaceX

Success all around for today’s SpaceX mission. The company successfully launched a Dragon spacecraft that is on its way to the International Space Station. SpaceX also successfully landed the first stage of its Falcon 9 rocket at Cape Canaveral. The weather was cloudy but it looks like it wasn’t enough to stop SpaceX from launching…

Goodbye, Rosetta — hogewash

The Rosetta spacecraft “landed” on Comet 67P/Churyumov-Gerasimenko at 11:19 UTC yesterday. The picture above was taken from a range of about 16 km during the descent. It shows objects about 30 cm across. The image below is the last image sent from the spacecraft at an estimated altitude of 20 m. The area shown is about 2.4 […]
