The station was designed by the Spanish architect and engineer Santiago Calatrava, who is famous for his futuristic, skeletal structures (he also designed the Oculus in NYC).
An international team of astrophysicists, led by researchers from @universitedeliege.bsky.social, has published new observations of Ganymede revealing a striking similarity between its auroras and those on Earth. A 🧵 about 🔭. #planetsci #jupiter #juno #aurora www.star.uliege.be/cms/c_136561...
For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb’s NIRSpec instrument, the team detected the faint glow from molecules high above the clouds. These unique data provide the most detailed portrait yet of where the planet’s auroras form, how they are influenced by its unusually tilted magnetic field, and how Uranus’s atmosphere has continued to cool over the past three decades. The results offer a new window into how ice-giant planets distribute energy in their upper layers. Two bright auroral bands were detected near Uranus’s magnetic poles, together with reduced emission and ion density in part of the region between the two bands (a feature likely linked to transitions in magnetic field lines).

In Belgium we pay around 1.5€/liter which is ~$6.7/gallon. It is not too expensive, considering that most cars are reasonably low on gas. The electricity for a corresponding EV car is nearly half of this.

Ever wondered what powers a solar flare? 💥
Solar Orbiter is finally giving us answers to this long-standing mystery.
The mission caught a 'magnetic avalanche' on the surface of the Sun just before a flare was released.

Merci !
This was tonight (19 Jan) over south east Belgium ( near Liège)
Rare and beautiful #aurora above #Esneux #Belgium (50.5 deg north) 19 Jan 2026
There is an increased chance of seeing the aurora tonight
The best odds across northeast Scotland where skies are looking clearer. Keep your eyes on the northern horizon! 👀✨
When you look at that bright point of light this evening, think of the Jovian fleet. #Juno (2016) is there right now, peering beneath the cloudy veil. #EuropaClipper (2030) and #ESAJuice (2031) are sailing through interplanetary space with a mission to explore Jupiter's ocean moons. (Credit: ESA)

More molecules and compounds vital to the origin of life have been detected in asteroid samples delivered to Earth by NASA’s OSIRIS-REx mission, strengthening the case that life’s building blocks originated in space. 🧪⚛️ physicsworld.com/a/components...
For the first time, astronomers have detected a coronal mass ejection from a star other than our Sun, and it was a big one – powerful enough to strip the atmosphere from nearby planets. That's bad news for the search for extraterrestrial life. Here's why: physicsworld.com/a/astronomer... 🧪⚛️🔭

Today I learned that NASA has a collection of free ebooks that can be downloaded as pdfs or ebub format.
The science books even include a children’s section with fun activites and coloring books!

Uranus and its classical satellites are shown on the left against a background of galaxies; Uranus and Neptune are shown on the right replete with reflective rings and clouds. NIRSpec and MIRI will be used to provide full spectroscopy of the Uranus and Neptune atmospheres.

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪
Artist's impression of Saturn's icy moon Enceladus, which has a frozen surface covering a deep ocean. Jets of water burst from cracks close to the moon's south pole.
Saturn's moon #Enceladus is a top target for us in our #Voyage2050 long-term planning period.
No space agency has ever landed on Enceladus. And yet this moon has enormous potential for new science, particularly in the realm of habitability.

A group of 16 people wearing white cleanroom suits pose for a photo inside a bright laboratory. They are standing and kneeling in front of a large spacecraft covered in shiny silver and gold thermal material, mounted on a vertical support structure. Some team members wear masks, and the background shows technical equipment and cleanroom walls.
