“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.

View this email in your browser A Change of Pace from Astronomy News As you may know, I have been writing science-fiction stories based on good astronomy as my retirement project. After a good number of rejections from the finest sci-fi magazines the world over, I am now finding some success. My ninth and tenth stories […] The post Two of My Science-Fiction Stories Published in May appeared first on Andrew Fraknoi - Astronomy Lectures - Astronomy Education Resources.
I was away on vacation the last week, hence no posts, but am now back to my usual schedule. In fact, I hope to be a little more consistent starting this summer because (if you follow me on the SGU you already know this) I am retiring from my day job at Yale at the […] The post Telepathy Tapes Promotes Pseudoscience first appeared on NeuroLogica Blog.
When the future arrived, it felt… ordinary. What happened to the glamour of tomorrow?
By extending the scope of the key insight behind Fermat’s Last Theorem, four mathematicians have made great strides toward building a “grand unified theory” of math. The post The Core of Fermat’s Last Theorem Just Got Superpowered first appeared on Quanta Magazine
Every week has brought more news about actions that, either as a collateral effect or a deliberate goal, will deeply damage science and engineering research in the US. Put aside for a moment the tremendously important issue of student visas (where there seems to be a policy of strategic vagueness, to maximize the implicit threat that there may be selective actions). Put aside the statement from a Justice Department official that there is a general plan is to "bring these universities to their knees", on the pretext that this is somehow about civil rights. The detailed version of the presidential budget request for FY26 is now out (pdf here for the NSF portion). If enacted, it would be deeply damaging to science and engineering research in the US and the pipeline of trained students who support the technology sector. Taking NSF first: The topline NSF budget would be cut from $8.34B to $3.28B. Engineering would be cut by 75%, Math and Physical Science by 66.8%. The anticipated agency-wide success rate for grants would nominally drop below 7%, though that is misleading (basically taking the present average success rate and cutting it by 2/3, while some programs are already more competitive than others.). In practice, many programs already have future-year obligations, and any remaining funds will have to go there, meaning that many programs would likely have no awards at all in the coming fiscal year. The NSF's CAREER program (that agency's flagship young investigator program) would go away This plan would also close one of the LIGO observatories (see previous link). (This would be an extra bonus level of stupid, since LIGO's ability to do science relies on having two facilities, to avoid false positives and to identify event locations in the sky. You might as well say that you'll keep an accelerator running but not the detector.) Here is the table that I think hits hardest, dollars aside: The number of people involved in NSF activities would drop by 240,000. The graduate research fellowship program would be cut by more than half. The NSF research training grant program (another vector for grad fellowships) would be eliminated. The situation at NIH and NASA is at least as bleak. See here for a discussion from Joshua Weitz at Maryland which includes this plot: This proposed dismantling of US research and especially the pipeline of students who support the technology sector (including medical research, computer science, AI, the semiconductor industry, chemistry and chemical engineering, the energy industry) is astonishing in absolute terms. It also does not square with the claim of some of our elected officials and high tech CEOs to worry about US competitiveness in science and engineering. (These proposed cuts are not about fiscal responsibility; just the amount added in the proposed DOD budget dwarfs these cuts by more than a factor of 3.) If you are a US citizen and think this is the wrong direction, now is the time to talk to your representatives in Congress. In the past, Congress has ignored presidential budget requests for big cuts. The American Physical Society, for example, has tools to help with this. Contacting legislators by phone is also made easy these days. From the standpoint of public outreach, Cornell has an effort backing large-scale writing of editorials and letters to the editor.
