Yet another new images of Ceres at the best resolution yet. Dawn is in a 15 day orbit of Ceres, so its point of view changes about 24 degrees per day.

The latest image of Ceres. None were released over the weekend, which is the status quo for the Dawn mission. Several long figures appear to extend from a very large crater, at about the 5 o'clock position.

A new animated sequence of images of Ceres is now available. My initial impression is that the bright spots are still unresolved, even at the improved resolution of 1300 meters per pixel. They appear blocky, which we associate with digital images that are poorly resolved. It would be useful to examine the still images from this sequence, once they become available. Link to image sequence, below:

Examined a still image of the bright spots from the most recent photographs. They appear much larger, in proportion to the known size of the crater that surrounds them, than could be expected of resolved objects.
We were told that the bright spots were unresolved at the previous limit of resolution-- ~ 2100 meters per pixel. This indicated that they were smaller than that. In the new image the brighter of the two spots appears about one quarter the size of the crater, or about 15 kilometers in diameter. The bright spots still appear to be smeared out over a much larger area than their maximum estimated sizes.

Now, if this is the asteroid the President proposes that our next manned mission should be heading to I could really see some benefit and some exciting science.

Looking further at one of the new images, under magnification, it appears that the bright spot to the side of the crater is of a notably regular shape; a rather long rectangle. The one near the center of the crater seems to be a square. It has three right-angled corners. The forth corner appears to be lopped off at a 30 to 45 degree angle. The sides of the rectangle and the square give the impression of being aligned, or nearly aligned with each other.

Michael, and everyone, here is another view.

Best view yet of Ceres' spots




The fascinating bright spots on the surface of the dwarf planet Ceres have come into sharper view.

What were initially thought to be just a couple of brilliant, closely spaced features at one location now turn out to be a clutch of many smaller dots.

The latest pictures were acquired by the US space agency's Dawn spacecraft on its first full science orbit since arriving at Ceres on 6 March.

The spots were seen from a distance of 13,600km.

Broken Domes because of a asteroid storm ? reflecting the little sun light there is of what's left standing after the storm ........

In October 2012, it was announced that 55 Cancri e showed evidence for being a carbon planet. It has eight times the mass of Earth, and twice the radius. Nikku Madhusudan, the Yale researcher, whose findings are due to be published in the Astrophysical Journal Letters says that the 3,900 °F planet is warmish — and is “covered in graphite and diamond rather than water and granite”.

Diamonds are not so heavy as gold...
Uranium is very Heavy.

No no no. It is just where the layer of dust has been swept away from the ship's hull at the center.

Only 3,000 miles away and the bright spots are still a mystery. If I were one of the team scientists I'd be going nuts in anticipation of a low pass over the site.

Update:

It's Crater-palooza on Dwarf Planet Ceres (New Photo)

A new photo from NASA's Dawn spacecraft shows the battered surface of the dwarf planet Ceres in unprecedented detail.

Dawn captured the image on May 23, when the probe was just 3,200 miles (5,100 kilometers) from Ceres. The photo's resolution is about 1,600 feet (480 meters) per pixel, scientists said.

Yes, the images are getting quite good. About twice as sharp now, as the best previous ones, and three times sharper when the survey orbit is reached, in a few days. There are supposed to be several images at the 480 meter/pixel inter-orbit stage (OpNav 9), but only one has been presented, so far. It looks as if the bright spots are in the adjacent field of view. Here's hoping a photo of these enigmatic objects will be released soon after the usual weekend hiatus.
