When you try to get kids excited in STEM:

GALAXY DONUTS!!! inspired by @insertdisc5‘s animated short Galactic Donut!! and a twitter exchange where she said i shouldn’t eat the galaxy donut because that didn’t work out well in the animation. so i made my own.

aaaaand now they’re too pretty to eat. truly this is the worst possible ending???

i tried very hard to make one of them look like the Actual Donut but? it turns out?? that edible spray paint is about as precise as a bucket of glitter??? oh well.

…can you hear me?

SCIENCE WARS – Acapella Parody (VIDEO)

Which field of science is the strongest?  Physics, Chemistry, Biology or Math?

We have the disciplines battle it out in our new Star Wars inspired, acapella song.

What Are the Bright Spots on Ceres?

Dwarf planet Ceres has more than 130 bright areas, and most of them are associated with impact craters. Now, Ceres has revealed some of its well-kept secrets in two new studies in the journal Nature, thanks to data from our Dawn spacecraft.

Two studies have been looking into the mystery behind these bright areas. One study identifies this bright material as a kind of salt, while the other study suggests the detection of ammonia-rich clays. 

Study authors write that the bright material is consistent with a type of magnesium sulfate called hexahydrite. A different type of magnesium sulfate is familiar on Earth as Epsom salt.

Researchers, using images from Dawn’s framing camera, suggest that these salt-rich areas were left behind when water-ice sublimated in the past. Impacts from asteroids would have unearthed the mixture of ice and salt.

An image of Occator Crater (below) shows the brightest material on Ceres. Occator itself is 60 miles in diameter, and its central pit, covered by this bright material, measures about 6 miles wide. With its sharp rim and walls, it appears to be among the youngest features on the dwarf planet.

In the second nature study, members of the Dawn science team examined the composition of Ceres and found evidence for ammonia-rich clays. Why is this important?

Well, ammonia ice by itself would evaporate on Ceres today, because it is too warm. However, ammonia molecules could be stable if present in combination with other minerals. This raises the possibility that Ceres did not originate in the main asteroid belt between Mars and Jupiter, where it currently resides. But instead, might have formed in the outer solar system! Another idea is that Ceres formed close to its present position, incorporating materials that drifted in from the outer solar system, near the orbit of Neptune, where nitrogen ices are thermally stable.

As of this week, our Dawn spacecraft has reached its final orbital altitude at Ceres (about 240 miles from the surface). In mid-December, it will begin taking observations from this orbit, so be sure to check back for details!
