Above: Combined MeerKAT and James Webb Space Telescope images. The star-forming region Sagittarius C, captured by the James Webb Space Telescope, is about 200 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. Huge vertical filamentary structures in the MeerKAT radio data echo those Webb captured on a smaller scale, in infrared, in a blue-green hydrogen cloud. Astronomers think the strong magnetic fields in the heart of the galaxy are shaping the filaments. For Webb, color is assigned by shifting the infrared spectrum to visible light colors. The shortest infrared wavelengths are bluer, and the longer wavelengths appear more red. NASA, ESA, CSA, STScI, SARAO, Samuel Crow

Back with a cover story by our fearless leader Michele Ferrara concerning the ever-present desire by some scientists (OK, effectively all scientists) to be the very first to the gate in making a major discovery. In this case, Nikku Madhusudhan of Cambridge, with his group's publication at https://arxiv.org/abs/2309.05566, followed soon-ish after by https://arxiv.org/abs/2505.13407, a follow-up to be found at https://arxiv.org/abs/2504.12267, and more digestible variations of recent re-assessments at such places as https://www.straitstimes.com/world/doubt-cast-on-claim-of-hints-of-life-on-faraway-planet.

That said, given how long it takes to get time on major facilities to obtain this data, how well the astronomical community (but certainly not the twitter/X-verse) is at tempering such studies with significant follow-up assessments of the same data, and the fact that such a somewhat early claim and the associated press are among the few reasons why the community outside of the astronomical community are aware of the amazing work done by, for instance, the JWST teams, we will all likely continue to let such cycles cycle until someone lands on that particular gold mine.

This issue marks a bit of a change in format under the direction of our fearless leader Michele Ferrara. PDF or not, there are only so many hours and pages one can commit to all that goes into writing, editing, and formatting. This is contrast to the seemingly unlimited (+/-) number of studies getting published and discussed that an editor would really like others to see. Add in the desire to include some additional context to bridge the gap between what a reader is reading and what else you (as the writer) think is worth stressing about the broader scope of the study, and you see how daunting a task it is for a few (5?) people (total) to try to sample everything bimonthly to everyone's satisfaction.

"I’m sorry I wrote you such a long letter. I didn’t have time to write you a short one." – Blaise Pascal (d. 1662. And, for those now asking in their noggin, “History never repeats itself, but it rhymes.” – Mark Twain, b. 1835)

After several years of feature articles surpassing the +10 page mark, the recent change now features more shorter articles covering a bit more variety but, with a 6-ish page limit, a less broad analysis and discussion for each.

This month's contribution from here (with my NASA Solar System Ambassador helmet on) is about the successful sample collection and return prep by OSIRIS-REx at Bennu. Astronomical mythology nut, I opted to wrap in a bit of the olde stories for both Osiris and Bennu before digging into the much older aspects of accretion theory and the upcoming issues of planetary defense.
