🚨 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

Sad to hear of the passing of physicist Claudio Maccone, former chair of the SETI Permanent Committee. I’ll remember his passion for the evolution of civilizations, his fight to keep the Moon’s far side radio-quiet, and his unmistakable Italian style. RIP Claudio. www.lastampa.it/torino/2025/...

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...

Powerful telescopes are key to discovering new phenomena and even life on other planets. This week, @bipisci.bsky.social is “Scoping Out the Universe” with @allplanets.bsky.social, where they discuss exoplanets and other recent discoveries. #podcast 🧪 🔭 Listen here: bit.ly/46GvdRW

Hubble Space Telescope images of interstellar comet 3I/ATLAS are out! These were taken 5 hours ago. Plenty of cosmic rays peppering the images, but the comet's coma looks very nice and puffy. Best of luck to the researchers trying to write up papers for this... archive.stsci.edu/proposal_sea... 🔭

SETI Live about 3I/ATLAS, the interstellar visitor. Observed with the @unistellar.bsky.social network and the @setiinstitute.bsky.social Allen Telescope Array, it’s likely a comet—not a spacecraft. As it approaches, we’ll uncover more about this mysterious object. www.seti.org/news/comet-3...

After endless delays, this should be a no-brainer. The La Palma site isn’t as good as Mauna Kea (especially for infrared), but it’s still excellent—and the TMT could finally be built while respecting the will of the Hawaiian people. Time to move forward. www.tmt.org/news/698

Watched Contact today with the @setiinstitute.bsky.social REU students. I’d honestly forgotten how much this movie shaped my path, it hit me all over again. Carl Sagan was such a brilliant mind and a kind soul. Big thanks to Exequiel from @skymapper.bsky.social for making it happen.

A community of amateur astronomers using @unistellar.bsky.social smart telescopes have been observing comet C/2025 N1 (ATLAS) – also designated 3I/ATLAS – and have managed to captured images of the interstellar comet. www.skyatnightmagazine.com/news/unistel...

Amazing work and reactivity from our @setiinstitute.bsky.social @unistellarusa.bsky.social citizen network of astronomers. We detected the interstellar comet this weekend with our mighty small telescopes. Some are obvious, others are very close to a bright star, But 3I/Atlas is here. #citizenscience

A 12h dip in TESS data hinted at a new exoplanet. So we rallied the SETI & Unistellar Network worldwide: 24 observers, 230 h of data, near-continuous coverage. Citizen science confirmed a planet lyrs away. Teamwork makes the cosmos work. www.seti.org/news/citizen... #Exoplanet #CitizenScience

Watch Arxiv tomorrow. I guess someone we all know is going to published a quick paper claiming that 3I/ATLAS is a spaceship.

Big news! A third interstellar object may have been discovered. Currently V=17-19 (elongated object???) from a few observations, and doesn't show any activity yet. Definitely something to follow up with our @unistellar.bsky.social and @setiinstitute.bsky.social network.

People with digital smart telescopes can now observe and confirm exoplanets from their backyard, helping NASA map nearby planetary systems found by TESS. This is a great example of how citizen science is crucial for planets with relatively long orbits. www.space.com/astronomy/ex...

On this day in 2015, same-sex marriage was legalized in the US, granting all couples the constitutional right to marry and establishing marriage equality nationwide.

Amazing first light from @vrubinobs.bsky.social ! The telescope’s sensitivity and image quality are stunning—~1100 asteroids detected in just a few nights. Imagine what 3 years of scanning the sky will reveal: millions of new worlds, right in our backyard.
