From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
At least eight spots can be seen next to the largest bright area, which scientists think is approximately 6 miles (9 kilometers) wide. A highly reflective material is responsible for these spots — ice and salt are leading possibilities, but scientists are considering other options, too.
In other words, they still have not confirmed through spectroscopy, that these bright spots are ice.
Note also that they have reduced the image’s brightness so that the bright spots do not over expose as much as in past images. This not only allows more details to come out, but it portrays Ceres’ very dark surface more accurately. Even so, the image still shows that surface as brighter than it actually is.
The press release also described a second image, showing a single lonely mountain on the planet’s horizon, rising up three miles from the planet’s surface, shown in the cropped image to the left. Overall this image, as well as the others, suggest that the surface of Ceres is generally far less rough than we should expect.
Another science mystery to unravel!
Every July, to celebrate the anniversary of the start of Behind the Black in 2010, I hold a month-long fund-raising campaign to make it possible for me to continue my work here for another year.
This year's fund-raising drive however is more significant in that it is also the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
This year's fund drive is also more important because of the growing intolerance of free speech and dissent in American culture. Increasingly people who don't like what they read are blatantly acting to blackball sites like mine. I have tried to insulate myself from this tyrannical effort by not depending on Google advertising or cross-posts Facebook or Twitter. Though this prevents them from having a hold on me, it also acts to limit my exposure.
Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.
