Ceres and Aliens

The bright dot on Ceres has the UFO community all a twitter.

As the Dawn probe approaches Ceres each day brings ever higher resolution photos. The bright dot first showed up as a large white blotch on the disk. Not a huge surprise, even Earth based images showed areas of the dwarf planet were much brighter.

As the spacecraft neared the dot has been revealed to be quite small. Indeed the images are quite intriguing, a very bright dot with a smaller dot directly beside it. The two features are near the center of a fairly large impact crater.

Of course the images are intriguing. Whenever something this odd shows up in a NASA mission image there is a group of folks who go off the rails entirely, the UFO/alien community. I looked at the image and went “Hmmmm?”. Then as I sat for a moment I wondered what the UFO websites were saying about this photo. A quick sampling showed that the UFO/alien community has let speculation run rampant.

The articles and YouTube videos are popping up, fueled by the latest Dawn mission image releases… It is an alien city, a giant spacecraft, and, of course Ceres is a fragment of the destroyed planet Phaeton. After the buzz about the UFO in orbit around asteroid 2004 BL86 the UFO community is ready for something new. Even the British newspaper The Daily Mail has let this “alien” speculation seep into its reporting.

The planetary science community has a more likely theory for the dot, a cryo-volcano. It is known that Ceres harbors a great deal of water. A vent of some sort allowing water to escape into space from a subsurface deposit is not that unlikely. The process would not be that dissimilar to what we have observed on comets. The location of the feature at the center of an impact crater is also interesting. Note that there is another light colored feature at the center of another impact crater on the lower left of the latest image. An older, less active or dormant cryo-volcano?

When looking at the image you have to remember that the surface of most asteroids and comets is actually quite dark, about the same as charcoal. Ceres has a v-band albedo of 0.09, thus only 9% of the sunlight is reflected by the surface. Anything bright white, like fresh ice, is going to be stunningly bright in comparison.

When Dawn arrives at Ceres and settles into orbit we will have our answers, the images should show the phenomena in exquisite detail. We just have to wait a few months. It would be totally cool if the bright dot did turn out to be some sort of alien artifact. But I have to agree with the mission team, it is probably some form of cryo-volcano, also cool.

One thought on “Ceres and Aliens”

  1. Perhaps aliens taking a flash picture of the Ceres?

    I told them to turn there flash off .Just like at the VIS, they never listen LOL
    aloha
