“Here's a view of Saturn's moon Prometheus, made from images captured with the narrow-angle camera on Cassini on December 6, 2015. Cassini was about 37,400 km from Prometheus when the images were acquired. Part of the F ring is visible in the background at the top.” — Jason Major
“This is a view of a ~2,000-km-wide vortex of swirling clouds above Saturn's north pole, imaged in polarized light with Cassini's narrow-angle camera on November 27, 2012. I've processed the original monochrome image to approximate the color of the area at the time.” — Jason Major
“An animation of three near-infrared images of Uranus captured by the JWST Space Telescope with assigned representative colors. During processing, I aligned the rings separately to reduce the bubbling effect caused by different inclinations, making the planet appear to rotate on an almost flat plane.” —Andrea Luck
Mars Express was launched by the European Space Agency in 2003, and is ESA’s first Mars mission. In one shot, you can see Mars as a half-lit disk, with Phobos, its tiny moon, hovering above. Right below Phobos is Olympus Mons, the solar system's largest volcano, towering 22 km high and 600 km across—about the size of Colorado. Posted by Andrea Luck, by way of Bad Astronomy.

Close to 900 million people across the Global South live in densely packed urban slums, which often sit in floodplains. A new study finds that one in three slum dwellers is at risk of "disastrous" flooding, a risk that is set to grow as warming spurs more intense rainfall around the world. Read more on E360 →
In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how. The post Quantum Scientists Have Built a New Math of Cryptography first appeared on Quanta Magazine
For centuries, the Native people of North America used controlled burns to manage the continent's forests. In an e360 interview, ecologist Loris Daniels talks about the long history of Indigenous burning and why the practice must be restored to protect against catastrophic fires. Read more on E360 →
The beginning of a RET poster session Research Experience for Teachers (RET) programs are an example of the kind of programs that the National Science Foundation funds which are focused on K12 (and broader) education. This summer I hosted a high school physics teacher in my lab for 6 weeks, where he worked on a brief project, with one of my doctoral students helping out in a mentoring role. Just yesterday was the big poster session for all of the participants in the program, and it was very enjoyable to talk with a whole cadre of high school science teachers from across the greater Houston area about their projects and their experiences. Readers may be more familiar with the sibling Research Experience for Undergraduates (REU) programs, which give undergraduate students the chance to work for 10 weeks or so in a lab that is very likely not at their home institution. REUs are a great way for students interested in research to get broad exposure to new topics, meet people and acquire new skills, and for some, figure out whether they like research (and maybe which topics are exciting to them). The educational goal of REUs is clear: providing direct research experience to interested undergrads, ideally while advancing a research project and for some small fraction of students resulting in an eventual publication. RET programs are different: They are intended as professional development. The teachers are exposed to new topics, hopefully a fun research environment, and they are encouraged to think carefully about how they can take the concepts they learn and translate those for the classroom. I am very much not an expert in education research, but there is evidence (see here, for example) that teachers who participate in these programs get a great deal of satisfaction and have lower attrition from teaching professions. (Note that it's hard to do statistics well on questions like that, since the population of teachers that seek out opportunities like this may be a special subset of the total population of teachers.) An idea that makes sense to me: Enhancing the motivation and job satisfaction of a teacher can have a larger cumulative impact on educating students than an individual research project for a single student. It would be a great shame if RET and REU programs are victims of large-scale cuts at NSF. The NSF is the only science agency with education as part of its mission (at least historically). All the more reason to try to persuade appropriators to not follow the draconian presidential budget request for the agency.
