The illusory truth effect is quietly killing collaboration.
Repeated falsehoods > facts. Memory > reality.
I don’t know the fix — but less doom-scrolling and more real human contact feels like a start.
What do you do as a leader?

Using a global stage to speak about injustice is important. What’s troubling is how selective that courage can be. Last night’s #GRAMMYs spoke loudly about U.S. issues, but stayed silent on Iran and the tens of thousands executed by its government. The world is bigger than one country.

Is the Galaxy Already Connected? Why the "Galactic Internet" Might Be Hiding in the Dark

If the Galaxy is already connected, we won’t find it by looking with a single instrument.
We need many eyes, everywhere, all the time.
That’s why projects like LaserSETI and @skymapper.bsky.social matter: distributed, complementary, and always watching the dark. www.seti.org/news/is-the-...

Un signal inédit autour de HD 206893 B : un candidat exolune révélé par l'astrométrie de très haute précision – Observatoire de Paris - PSL - Centre de recherche en astronomie et astrophysique Une étude dirigée par un chercheur de l'Observatoire de Paris-PSL au sein du Laboratoire d'instrumentation et de recherche en astrophysique (LIRA - CNRS / Sorbonne Université / Université Paris Cité)…

Cool discovery! If the exomoon interpretation is right, this object is enormous ! It orbits HD 206893 B at ~0.22 AU on a highly tilted orbit (~60°), blurring the line between a giant exomoon and a low-mass companion. Frontier science in action. observatoiredeparis.psl.eu/un-signal-in...

US Senate passes bill to boost federal science spending after White House sought major cuts The U.S. Senate voted on Thursday to approve billions of dollars in funding for federal science agencies, rejecting deep cuts proposed by President Donald Trump in space and other areas.

A big moment for US science today. The Senate joined the House in passing the FY26 minibus funding NASA and NSF. Take a moment to thank those involved in this grassroute campaign and recharge. The work to secure the future of US science continues. www.reuters.com/world/us-sen...

My 2c: It was about time a billionaire fund a space telescope and we should all support this initiative. Of course, I love the fact that it will have a coronagraphic camera.

2026 brings a dense lineup of space science milestones: crewed lunar missions, new observatories, planetary exploration, and data releases that will shape the next decade.

SkyMapper: Mapping the Entire Sky, All the Time

Proud of our @setiinstitute.bsky.social partnership combining @skymapper.bsky.social global telescope network with SETI scientific expertise opens continuous, AI-augmented sky monitoring to scientists everywhere. Science shouldn’t be held back by centralized access.

Happy solstice to all humans on this beautiful planet.
Longest night in the north, longest day in the south.
Under one sky, connected.

On Nov 25, asteroid Nephele passed in front of a distant star. For ~20 seconds, the star disappeared.

That blackout let #astronomers measure a 100 km-wide asteroid orbiting between Mars and Jupiter.

Quiet moments like this are how we map and understand what’s moving through our solar system.

Rare image of Tatooine-like planet is closest to its twin stars yet Discovered in old data, new exoplanet was formed after the dinosaurs went extinct

Astronomy has a long memory.
Six years after it left the telescope, the Gemini Planet Imager l just revealed a new exoplanet — hidden in plain sight in old data. A reminder that archives still hold discoveries waiting for the right tools and questions news.northwestern.edu/stories/2025...

What? The store doesn’t have it ?

#ICYMI: During a special #SETILive last week, @allplanets.bsky.social introduced his latest project -- @skymapper.bsky.social. The company is setting out to decentralize astronomy through a network of connected, personal telescopes. Watch the full episode: youtube.com/live/zbDWsEF... 🧪 🔭

Conservative Hard-Liner Is Elected as Chile’s President

The poison is spreading and we share responsibility. How did the choice narrow to a moderate communist vs. a far-right candidate? Social media’s polarization keeps erasing the center, leaving societies trapped in extremes.

Radical idea: Generation Beta may be the last humans as we know them. Kids born today will grow up with genetic upgrades, AI-enhanced minds, and lifespans with no clear limit. If you’re raising them, you’re holding the hinge of history, the final “old humanity,” and the architects of what comes next

In our latest #SETILive #podcast, @allplanets.bsky.social asked Dr. Ariel Graykowski what it meant that an analysis of #Comet3I/ATLAS revealed a lack of water in the coma. Listen to the full episode: feeds.libsyn.com/462636/rss 🧪 🔭 👩‍🔬

Recent events raise legitimate questions about the president capability to carry out the duties of the office. When medical concerns or persistent communication issues become impossible to ignore, it’s not about politics — it’s about ensuring that the country is being led with clarity and stability.

American Airlines says all planes impacted by Airbus glitch have been fixed American Airlines said Saturday that aircrafts impacted by an Airbus recall have received the software fixes necessary to resume flying.

Space exploration isn’t a luxury or sci-fi — it’s infrastructure. Airbus just grounded 6,000 A320s for urgent software repairs after solar flares threatened to corrupt flight-critical data. Space weather affects every nation, every sky, every system. www.cnbc.com/2025/11/29/a...

Fantastic work by Ariel Graykowski and our @setiinstitute.bsky.social citizen scientists.
Comet C/2025 K1 (ATLAS) is breaking apart — and some of you caught it live. After passing 0.3 AU from the Sun, it erupted, and three days later a third appeared.

K1 is now officially in pieces.

Our CEO @allplanets.bsky.social visited the HR MacMillan Space Centre to talk exoplanets and how SkyMapper’s decentralized network will accelerate discovery.

Huge thanks to the @setiinstitute.bsky.social team for hosting us and giving us space to share the future of sky observation. 🌌

How many more Cloudflare, AWS, or GCP outages do we need before we admit our internet is built on a few fragile chokepoints? These failures aren’t accidents — they’re the cost of centralization. Time to look seriously at decentralized infra as a real path to resilience. #web3

Gave two talks at the MacMillan Space Centre in Vancouver on Friday evening to a wonderfully diverse and curious crowd. We explored the @setiinstitute.bsky.social , LaserSETI, and of course @skymapper.bsky.social Loved the questions, the energy, and the conversation.

New observations of comet 3I/ATLAS show it’s exactly where predictions said it would be. No mystery, no breakup.

Scientists shouldn’t post rough guesses as headlines — and journalists should stop amplifying them. Let’s focus on the real science, not manufactured drama.

At USF, our CEO @allplanets.bsky.social showed how anyone can map the sky through @unistellar.bsky.social and SkyMapper with decentralization and real rewards pushing discovery forward.

Thanks to our partners The Canary Global Foundation and Light Bridges for helping make it real.

Four Republicans vote with Democrats in effort to end Trump tariffs on Canada | CNN Politics The Senate passed a resolution aimed at ending President Donald Trump’s tariffs on Canada, with four Republicans joining Democrats to rebuke the administration’s trade policies a day after they voted ...

The cracks are showing. Even Republicans are turning against Trump’s absurd trade wars. The Senate just voted to kill his tariffs on Canada — and did the same for Brazil yesterday. Maybe this is the start of a rebellion against blind, illogical leadership.
