Rare Hot Jupiters Could Reveal How All Giant Planets Form - Eos A new analysis shows that the way massive planets migrate after their formation helps determine whether they have companion planets. The process hints at planetary formation in general.

I know *I* need a break from all the doom, and maybe you do too. So here's my latest article for @eos.org : could "hot Jupiters" (massive planets orbiting very close to their stars) help us understand how all giant planets form, including our own Jupiter? eos.org/articles/rar... 🧪🔭

“I think Jupiter could have become a hot Jupiter. Luckily for us, it didn’t.” Agreed, @jcbecker.bsky.social

4,000 gone: Inside NASA’s brain drain In exclusive interviews, ex-NASA scientists speak out on the impact of the agency's mass departures.

"The secret sauce has been poured down the drain," says David Draper, former Deputy Chief Scientist of NASA, over the recent firing or departure of 1000s of NASA employees, which will be catastrophic for the legacy of the US🇺🇸😖🚀

Advocacy Action Center The Planetary Society is organizing a new space constituency that is educated, empowered, and loud.

We now have a petition anyone around the world can sign to help save NASA science by urging the United States Congress to reject the proposed 47% cut to NASA’s science programs, before the 2026 budget is finalized.

We need 1,000 signatories by June 12, 2025.
Help us save NASA! ✍️

This is insane, and sabotages the future of US science—and it’s so easy to see why…

AI, quantum, etc., all started as niche research 10, 20, 50 years ago. They’re “trendy” science of national importance today because of decades of investments in broad, fundamental research.

i think the biggest public relations coup AI boosters scored was calling it “AI.” people genuinely think it is an intelligence, and that when they query it, it is providing reasoned answers

What I told my students about the threats to evolutionary science I was floored by the question, but it matters. With U.S. funding crashing, what will happen to the future of the field?

From a good friend on another platform:

“I think the reality is academic science is now in its second existential crisis within a decade, and that’s a sign of deep structural problems…one of which is failure to reward things like public-facing communication.”

🧪 Though a doubling of NSF's budget might seem far-fetched, that's exactly what Congress said what's needed to maintain national competitiveness in science & tech.

The reality is worse than we thought.
The White House proposed the largest single-year cut to NASA in history. We urge Congress to reject this proposal and work on a bipartisan solution for a strong space program that reflects humanity’s potential.

"In the long term, severe reductions to science funding could damage the economy, according to new research. A report by economists at American University in Washington DC estimates that a 50% reduction in federal science funding would reduce the US gross domestic product by approximately 7.6%."

"Days ago, the Administration’s nominee to lead NASA called for a “new golden age of science and discovery” at the agency. The proposed budget from within the White House — which cuts NASA science by 47% — would plunge NASA into a dark age instead."

NASA is something every American can be and should be proud of. And for every dollar spent on it, it returns more on that investment to the economy.
Example: Their 2023 budget was $25B, and they added over $75B to the economy that year.
This is a horrible decision.

Massive cuts to NASA science proposed in early White House budget plan The preliminary version of President Donald Trump’s budget proposal to Congress, known as a “passback,” would cut the agency’s science budget funding nearly in half.

First the rumour was a 20% budget cut. Then, 50%. Now the president's NASA budget is out and it's a 68% cut to astrophysics ($1.5B to $487M).

Even if this gets reversed in four years, we will *never* recover the missions, partners, people who will be gone.

Cuts to #science of >50% at NASA and >75% at NOAA would end US climate and space science research.
