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.

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...

SkyMapper @skymapper.bsky.social · 12d

“What if a piece of Earth was floating out there as an asteroid?”

On #SETILive, @allplanets.bsky.social and @asrivkin.bsky.social explored asteroid 2024 YR4 and its 4% chance of hitting the Moon in 2032.

A risk for satellites, but a rare gift for science.

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...

New comet SWAN25B already bright but near the sun

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...

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

SkyMapper @skymapper.bsky.social · Sep 5

First light in the Caribbean ⭐️

M27 (the Dumbbell Nebula), captured in Puerto Rico and logged on #SkyViewer.

Our first Caribbean telescope with @setiinstitute.bsky.social is already streaming data into the SkyMapper network - one step closer to a global, decentralized observatory.

Nice; check our partners such as the @unistellar.bsky.social telescopes and @skymapper.bsky.social network if you want to contribute to citizen science and more. We also have local chapters of SETI institute fans in several cities.

Franck Marchis @allplanets.bsky.social · Aug 30

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
