NASA spacecraft Dawn is approaching the dwarf planet Ceres and sending back amazing images of the planet.
Recent images show numerous craters and unusual bright spots that scientists believe tell how Ceres, the first object discovered in our solar system’s asteroid belt, formed and whether its surface is changing. As the spacecraft spirals into closer and closer orbits around the dwarf planet, researchers will be looking for signs that these strange features are changing, which would suggest current geological activity.
Chile’s Villarrica volcano erupted this morning producing a spectacular lava fountain!! More info here and pics at Erik Klemetti’s ERUPTIONS blog on wired.com. Gif above from this POVI time-lapse at youtube.

The eruption spread ash over the neighboring region and an accompanying lava flow melted snow on the slopes of the volcano (see below) creating some small volcanic mudflows and debris flows. Currently, over 3,300 people have been evacuated from the small towns around Villarrica, including the vacation town of Pucón. The eruption started at ~3 a.m. (local time) and TV footage showed the deluge of lava bombs that rained down on the slopes during the peak of the eruption.
Another post, another awesome gif from NASA!! This gif (made by CauseScience) shows the aurora borealis in the sky as the sun rises, ending with the two light sources ‘touching’!! The video this gif was made from was taken from the International Space Station – #sunrise touches #aurora.

Update: The gif CauseScience made from the youtube video is not nearly as good as the vine posted by @Space_Station![tweet https://twitter.com/Space_Station/status/563069569078927362]
crestwind24- I am spending part of my day processing images (micrographs) that I took earlier on our labs confocal microscope. As I mentioned in a previous CauseScience Friday, the confocal allows me to take amazing pictures of neurons and their axons and dendrites. Today I am taking many images taken through the depth of a worm and making 3D animations. This allows you to see the morphology of the axons – or where they are in space. Below is a partial low-res GIF I made of one of my animations – it shows two neurons and their axons in C. elegans!!
psgurel- Part of joining a new lab involves developing a new project. Today, I’m doing some test runs as an initial step in developing a method for imaging different conformations of actin filaments for cryo Eelectron Microscopy. First, I have to coat EM grids in a mechanism that will allow the actin to bind properly, so I’m surveying different ways of coating EM grids. Wish me luck!
