May 21, 2015: Light on Ceres
http://cellar.org/2015/ceres-light.jpg
This is the best image so far of the bright spot on Ceres - a "dwarf planet" which is the largest item in the asteroid belt; dwarf planet is a term which is not found to be derogatory. Gravdigr had previously pointed to Ceres in another thread, but that was two and a half months ago; now NASA's Dawn spacecraft has gone and orbited the dwarf (the subplanet, not Gravdigr) to get a better shot, and the strange, unsolved mystery light on the rock is much higher resolution, and we can all stare in wonder... because, obviously... ...we found them. NASA's so-called "scientists" don't know why that light is there. They are claiming that this is not the alien horde waiting to attack our home planet, but rather might be a patch of reflective ice, or something volcanic, or outgassing. What do they know? I outgas all the time, and it looks nothing like this. via mashable |
What's the relative size of the bright spots? I have no idea how big Ceres is...

This image from Wikipedia shows the relative size of the Earth, Moon, and smaller Ceres.
Attachment 51704 Pretty cool that this planet is so close, between Mars and Jupiter. |

And I couldn't find any mention of the size of the spots, so I looked up the diameter of Ceres (590 miles) and measured how many pixels across it was in this image, and then measured the pixels of the two spots and did the math to get their size in miles. (They are 20 miles across)

That's a good-sized alien base, then. Worth conquering.
|
Let's hope that it is Vulcan's and not Klingon's, or Romulan's.
|
for the history deficient, 20sq mile cube is (was) the size of the fusion reactors on Altair IV (aka Forbidden Planet).
And we all know how well that turned out. |

All day, I've been researching purchasing a new-to-me camera off Ebay. I need to sell a couple more things to get enough funds built up in PayPal, but I'm toying with either a Panasonic DMC-FZ70 (which is a very nice super zoom upgrade of my current decade old camera) or going up to a DSLR like the Nikon D5100. This weekend, I'm going to list my old 35mm Nikon gear and hope to get $100 or so. That will put me in striking distance of a DSLR. |
Another possibility: It's a bird turd stuck to the telescope's lens.

They got closer again:

that would make the spots 21.2 miles across. give or take a mile, confirming Glatt's earlier math. http://cellar.org/2015/ceresspot-20150606.jpg |
Here's an interesting YouTube dated 8/6/15...

This is great, they keep on circling Ceres and taking more and better pics. This morning's release:
http://www.jpl.nasa.gov/news/news.php?feature=4714 http://cellar.org/2015/ceres20150909.jpg This is 600 by 600 pixels and each pixel is 450 feet (140 meters). |
Looks like it might be dusk there, and the inhabitants of the city are just beginning to turn on their lights.
|
That looks like the stippling pattern of snow on rock, to me.
