Colors of the aurora: Red, green, purple… black? 🤔
Mysterious “black auroras” are real, and they’re not like the northern and southern lights you’ve seen before. Inside these dark spots, strange physics is at work — and a NASA rocket just launched from Alaska to reveal it. 🚀 ✨

#PPOD: Olympic View 🇮🇹
The Copernicus Sentinel-2 mission brings us a striking view of northern #Italy, highlighting several key Olympic venues for the 2026 Winter #Olympics.
Also known as the Milano Cortina Games, this year’s Olympics are geographically widespread, with events taking place simultaneously across northern Italy at venues including Milan, Bormio, Livigno, Anterselva, Cortina d’Ampezzo, Predazzo, Tesero, and Verona.
The upper part of this cloud-free image is dominated by the Alps' mountains and valleys, where most venues are located.
To the northeast lies Cortina d’Ampezzo, the town that lends its name to this year’s Games. Often called the Pearl of the Dolomites, Cortina sits at the heart of these dramatic mountains, also a UNESCO World Heritage site. A renowned winter sports resort, Cortina also hosted the 1956 Winter Olympics.

Desde aquí queremos felicitar a todo el personal del aeropuerto de #Barcelona El Prat por la gran labor en un día complicado como el de hoy. Felicitar también a las tripulaciones y como no, al equipazo de la torre de control. Una jornada con una treintena de aproximaciones frustradas que implican muchísimas coordinaciones y operando con una sola pista durante buena parte de la mañana. Enhorabuena, compañeros 👏👏.
Our Crew-12 mission is heading to the @Space_Station soon!

☄️ Ancient Martian Water Revealed
By employing advanced neutron and X-ray CT scans, Danish researchers have uncovered a hidden reservoir of water-bearing minerals within the famous "Black Beauty" meteorite.
This 4.48-billion-year-old specimen offers a rare chemical window into Mars' infancy, suggesting that the Red Planet held significant water reserves much earlier than previously confirmed.
The discovery of these tucked-away minerals not only reshapes our understanding of Martian geology but also intensifies the ongoing search for signs of past habitability in our solar system.
