Here's to another year discovering the universe with YOU 🥂#citizenscience #year2025
🌟 Unistellar congratulates Ken’ichi Nomoto and Stanford Woosley, winners of the 2026 Shaw Prize in Astronomy!
Their pioneering work on stellar explosions and the origin of the elements has reshaped the understanding of how the Universe creates the building blocks of planets, stars...and even ourselves ! 💥✨

At 11:23 GMT today, asteroid 2026 JH2 will make a close flyby of Earth — just ~90,000 km/56,000 miles away — with zero impact risk. 🪨🌍
Too faint to see with the naked eye (mag 11.8), but it may be visible with a telescope for keen observers 👀🔭

Artemis' commander Andrew McCarthy teams up with Reid Wiseman : a visual collaboration bringing the Moon’s far side into a whole new light 🌕
NASA Artemis II commander Reid Wiseman teamed up with astrophotographer Andrew McCarthy to create breathtaking new images of the Moon’s far side, blending human spaceflight with cutting-edge astrophotography techniques.
A powerful reminder that the next era of space exploration is as much about inspiring people as it is about pushing boundaries.
YOU can also take stunning spatial pictures with Unistellar and tag us with the hasthags #Unistellar #Unistellarastrophotography ! 📸

#PPOD: The Bubble Nebula 🫧
The Bubble Nebula, also known as NGC 7635, is a massive cosmic balloon located approximately 7,100 light-years from Earth in the constellation Cassiopeia. This seven-light-year-wide structure was created by the intense stellar winds of a super-hot O-type star, which is roughly 45 times more massive than our Sun.
As these winds blast outward at four million miles per hour, they push against the cold interstellar gas to form the glowing, translucent shell seen in Hubble’s iconic 26th-anniversary imagery. Interestingly, the central star appears off-center because it is pushing against a denser region of gas on one side, which resists the bubble's expansion and creates its unique, asymmetrical shape.

NASA’s 04/02 APOD : Seeing Titan. 🪐
NASA highlighted a fascinating view of Titan, Saturn’s largest moon, whose surface remains hidden beneath a dense, hazy atmosphere.
🌌 Cassini data and recent models reveal the challenges of observing this hydrocarbon-rich world, home to liquid seas and complex organic chemistry.

Clear skies!
Inspired by @timruss2 I set out on a quest for supernovae last night with my @Unistellar#eVscope. The Type II #supernova#SN2026kid shines with a brightness of 15.6 mag in the beautiful edge-on galaxy #NGC5907. It's the explosion of a star at least 8 times the mass of our Sun.
@Unistellar Captured this with my telescope in 30 minutes last night from my back yard in Los Angeles using the Unistellar EVscope . This supernova is in a galaxy 50 million light years away.

Il semble bien que les Ppr (ou LRD) soient des étoiles trous noirs : le processus de formation des trous noirs supermassifs.

@DivingInMyBrain Bonjour, nous n’avons pas annoncé de projet en ce sens pour le moment. Nos choix de capteurs visent surtout le meilleur équilibre entre sensibilité, rapidité et expérience d’observation.
NASA's image of the day : Comet R3 PanSTARRS Behind Satellite Trails. ☄️
NASA highlights a striking image by Uli Fehr: Comet R3 PanSTARRS Behind Satellite Trails.
🌌 If skies are clear, amateur observers may have a chance to capture Comet R3 PanSTARRS before dawn, which is around magnitude 8. Look towards the eastern sky, in the constellations Pegasus and above Pisces in the northern hemisphere.
Clear skies !
Go on a Search for Exoplanets ! 🪐
On Earth Day, we celebrate our planet, which is just one among billions. And today, you can help discover other planets orbitting around other stars with our Exoplanet transits mission.
