Zooming in on Ceres’ mysterious double bright spot
Cool image time! Dawn’s science team has released a much closer image of the double bright spots on Ceres.
The spots can now be resolved into a half-dozen spots of varying size, all of which suggest material with a high reflectivity, likely ice. They look so bright because the rest of the dwarf planet’s surface is so dark.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

What seems most reasonable is that the crater is full of ice and these white spots are the result of more recent asteroid strikes.
I wounder what Richard C. Hoagland thinks they are?
Is it a set of white spots on a grey planetoid, or is it grey spots on a dark planetoid?
Ceres is very dark, as are most asteroids. The bright spots are also dark, because there is much less light from the sun out there in the asteroid belt. They aren’t grey, however. Assuming they are ice, they are white but dimly lit.
They appear so bright in these images because the surface around them is so relatively dark and needs to be brightened to bring its details out.
