Aaaaand my talk at #sagan2026 is done! Hope I got everyone excited about what Roman could reveal about exoplanets across the galaxy.

It’s time for #sagan2026!!! Exoplanets with Roman. Can you guess how many different ways Roman will detect planets??

How every generative AI company appears to me:

Three panel comic. The top panel shows two stick figure. One hands a ball to the other saying 'I made this'. The other receives it and says 'You made this?' In the second panel, the second stick figure, now alone, ponders the ball. In the third panel, the second stick figure, still alone, smiles slightly and says 'I made this', still holding the ball.

I know I'm preaching to the choir but the highlighted sentences in the proposed OMB rules are just appalling. Publishing federally funded science results isn't necessary? It's better to get the results and then... sit on them? My brother in Christ, that is truly the least useful outcome.

A screenshot of the some of the text of the proposed OMB rules:
"Section 200.461—Publication and Printing Costs
OMB proposes to revise § 200.461 related to publication and printing costs to make plain language revisions, including removing the word “promotion,” which is not the specific subject of this section. As § 200.421 provides the policy for “advertising and public relations” costs, OMB wants to ensure that the term “promotion” does not create an independent basis for allowing such costs under this section. To extent that advertising and public relations costs are not permitted under § 200.421, that section would govern. Furthermore, OMB is revising the section to make publication costs unallowable unless such costs are expressly required by statute or approved in advance by the Federal agency on a case-by-case basis. This change reflects OMB's objective to strengthen stewardship of Federal funds and ensure that Federal financial assistance is directed toward achieving the programmatic objectives of the award. Publication costs are not inherently necessary to carry out the core programmatic objectives of most Federal awards. In many cases, such activities are discretionary, vary widely in scope and costs, and may serve institutional, professional, or reputational interests rather than the specific objectives of the Federal program. Absent statutory authority or award-specific requirement, allowing publication costs as a charge to Federal awards creates inconsistent charging practices and increases the risk that Federal funds are used for activities that are ancillary to program performance. By limiting allowability to circumstances in which publication is required by statute or explicitly incorporated into the award, this change would ensure that such costs are incurred only when they are directly tied to a statutory or programmatic requirement."

The sentences about how publications aren't necessary and are self-serving are highlighted.

Tech bros not using Lord of the Rings names in their terrifyingly dystopian technology challenge. ca.pcmag.com/news/16760/f...

Screenshot of the PC mag article linked in the post, which reads
"Despite a flood of objections, the Federal Communications Commission has approved a startup's plan to launch a controversial satellite that’ll use a giant mirror to reflect sunlight to Earth after dark

On Thursday, the FCC granted the California-based Reflect Orbital permission to launch and operate the satellite in low-Earth orbit using the requested radio spectrum. The reflected light from satellite is supposed to span an area of about three miles wide on the ground.

The approval is only for one satellite, dubbed Earendil-1, which is meant to test Reflect Orbital’s technology to shine the sunlight back to Earth. The satellite will boast a steerable thin-film reflector"

And the sentence fragment "The approval is only for one satellite, dubbed Earendil-1' is highlighted.

Check out this MASTERPIECE of accessibility from Joop Schaye's group - a gorgeous sonification of a galaxy growth simulation. Hear black holes merge, star formation rates rise and fall, and the whoosh of dwarf galaxies flying by. Beautiful AND informative! (Credits next post!) (📣 Sound on! 📣)

Challenging three hour hike for the conference social activity today but WE MADE IT and were rewarded with a fantastic outdoor dinner at a beautiful vineyard overlooking the Danube.

Don't mind me, just saving the DRC President's speech to the Congolese men's soccer team for next time my son* is in a tournament. *The 'rich' town team did win their division. 😅😭 So that just means we need a sequel!!

Screenshot of a Guardian live blog entry, which reads:

Keir Starmer’s words of encouragement for the England team ahead of the World Cup were criticised in some quarters for being rather lukewarm, but you can’t say the same about DR Congo’s president Félix Tshisekedi. He addressed his nation yesterday with a speech marking the 66th anniversary of the country’s independence. Media site 7sur7 reports in it he spoke directly to the Congolese squad, saying:

"To our Leopards, who are preparing to face England in the Round of 32, I want to send a simple message: step onto the pitch with the serenity of those who have already honoured the nation, but also with the audacity of those who know that history has not yet had its final say.

Play with discipline, courage, intelligence, and above all, without regrets. You have already made the hearts of Congolese men and women beat faster, you have already made an entire people proud, and we continue to believe in you and in your ability to go further, to surprise again, to push back the limits of what is possible, and to write, under our colours, a new chapter in our national greatness.

Whatever the adversity, the Democratic Republic of Congo will accompany you with its fervour, its prayers, and its unwavering support. Step onto the pitch with the strength of an entire people united behind you."
