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. www.seti.org/news/skymapp...

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.

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...

#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... 🧪 🔭

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. www.nytimes.com/2025/12/14/w...

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.

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.

What do we really know about interstellar comet 3I/ATLAS? I sat down with planetary astronomer Ariel Graykowski for an honest, curiosity-driven discussion—no promo, just science. #astronomy #comet3I www.youtube.com/live/zaVO-uf...

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. www.cnn.com/2025/10/29/p...

☄️ What happens when a visitor from another star system drops by? Our CEO @allplanets.bsky.social and Ariel Graykowski joined @setiinstitute.bsky.social’s #SETILive to discuss Comet 3I/ATLAS - the third known interstellar object ever detected! www.youtube.com/watch?v=zaVO...

Imagine a single, unified telescope network spanning the globe, capturing scientific data 24 hours a day. That is our mission. #SkyBridge is the first step in decentralizing discovery, connecting #astronomy to a world-changing purpose. Join the movement⬇️ bujxgc-va.myshopify.com/collections/...

Congratulations to Jill Tarter — astronomer, innovator, and founder of the @setiinstitute.bsky.social — for receiving the California Academy of Sciences Fellows Medal! Her dedication to science has inspired generations, including myself. Always a joy to talk with her about @skymapper.bsky.social

Everyone remembers the first time they saw Saturn’s rings—often through binoculars. ✨ With ENVISION, we’re bringing that magic into the modern world: smart AR binoculars that connect people to the sky. Preorders are open: unistellar.com/envision

R.I.P. George F. Smoot (1945–2025). Brilliant out-of-the-box thinker, true francophile & kind soul. Nobel Laureate who used NASA’s COBE to map the early Universe and reveal the seeds of today’s galaxies. apc.u-paris.fr/fr/memory-ge...

Launched in 2020, this SpaceX satellite joined 7,600+ siblings before burning up safely—no direct danger (maybe for our ozone layer?), just a cosmic fireworks. Soon the @skymapper.bsky.social network will be catching these streaks in real time. #Space #Starlink

Fun SETILive and interesting discussion with @asrivkin.bsky.social on 2024YR4 and its potential impact on the moon in 2032. We are going to need a Planetary Defense program for the Moon if we establish permanent bases there...

It’s the first time I’ve ever watched Jimmy Kimmel, but today feels special for our country. Our freedoms and the principles that make this a truly free nation—free speech , respect for science, and a fair system of justice—are what unite us as Americans. Let’s stand together to protect them.

🚨 Possible brightening in comet 3I/ATLAS! Observers report an uptick since Sept 17 (UTC). Our @Unistellar data shows 2 points brighter than predicted—promising but sparse. As 3I nears the Sun it’s getting tougher to spot, so more observations in the next few nights are key! #exocomet

When you tune out the amplified extremes, humanity looks far less like a battleground and far more like a vast network of mostly decent people quietly making life better. Let’s remember this please. #future

Project Hail Mary, based on one of the best sci-fi books I’ve read recently, is about to hit the screen. The story? A teacher-turned-astronaut who meets an alien named Rocky. I can’t wait! www.youtube.com/watch?v=vkcE...

Friday night bliss: a fog-free, dark sky, my @Unistellar ODYSSEY at my side, great music in my ears and a good book in hand. Nights like this remind me why I fell in love with the stars… here’s to many more. #astronomy

Beyond politics, it’s time for all of us to confront the radicalization of some young men, likely accelerated by COVID isolation and social media, an alarming sign of a society that has lost its values, neglected to properly guide its youth, and failed to simply love them. #education #family

There’s a new comet in the sky, although, as of Friday morning, it was not yet officially confirmed. SWAN25B is best positioned for observers in the Southern Hemisphere. Because it’s so close to the sun, it will be tricky to spot. #comet #astronomy earthsky.org/space/new-co...

Several citizen astronomers of the @unistellar.bsky.social network watched the eclipse beginning of this week. Here some images by Aad V. who lives in Netherlands. Don't miss the next one on March 2-4, 2026! #LunarEclipse #astronomy

One conference, three presentations by our team! #EPSCDPS2025 in Helsinki was a blast. Our CEO @allplanets.bsky.social showed the potential of a decentralized network of telescopes built on @unistellar.bsky.social for image-based photometry & astrometry at scale. Let's map the sky, all the time.

The coming months promise to be a treat for skywatchers. Whether you’re in the northern or southern hemisphere, the night sky will feature a parade of comets—each with its own story and best window of visibility. www.seti.org/news/an-autu...

We'll be at EPSC-DPS 2025 in Finland next week🪐 Come meet our CEO and co-founder @allplanets.bsky.social and learn about our journey, mission and progress in building the first #DePIN infrastructure to map the sky. Schedule a meeting here: calendly.com/fmarchis-astro

Congratulations to Natalia Oliveros-Gómez and Laura Ramírez-Galeano for leading the RECA education project, bringing astronomy to students across Colombia—recognized today at #EPSCDPS25

Diversity doesn’t sustain itself—it endures only if we keep fighting for it. Grateful to the members of #EPSCDPS2025 for leading the way to keep science open and inclusive for all.

We’ve started the extension of the SkyMapper network to sites around the world. This week in the Caribbean where I took a SkyBridge to Puerto Rico. Connect with us if you want to host one of our stations to help us map all of the sky, all of the time. #citizenscience #astronomy

Almost done! The three LaserSETI stations are set and connected. Now we need to fix connection issues and the instruments will be ready to search for laser pulses from ET… here in Puerto Rico. Thank you Isla Mayaguez and Universidad de Puerto Rico !

Setting up our LaserSETI stations with @setiinstitute.bsky.social and @profabelmendez.bsky.social team at Isla Mayagüez. It’s sunny, it’s hot but I am glad we are here. #science

Our recent #SETILive wasn't the first time we talked about an exoplanet in the habitable zone around Alpha Centauri. Four years ago, @allplanets.bsky.social chatted with Dr. Kevin Wagner about his newly published paper in Nature Communications. 🧪 🔭 Watch more: www.youtube.com/watch?v=6wkp...

Retracting the “arsenic life” paper 15 years later is too late. Science advances through debate & replication, not by rewriting history to look cleaner. Controversy drives progress—erasing it doesn’t. @science.org www.science.org/content/arti...
