#PPOD: This picture from the NASA/ESA/CSA James Webb Space Telescope features the gravitational lensing of the quasar known as RX J1131-1231, located roughly six billion light-years from Earth in the constellation Crater. It is considered one of the best lensed quasars discovered to date, as the foreground galaxy distorts the image of the background quasar into a bright arc, creating four images of the object.

Every once in a while, our solar system receives a fleeting visitor from the depths of our galaxy. On July 1, 2025, NASA’s ATLAS telescope in Chile discovered Comet 3I/ATLAS, the third known interstellar object ever detected, following ʻOumuamua in 2017 and 2I/Borisov in 2019. What makes it interstellar? Its orbit is hyperbolic, meaning it doesn’t loop back around the Sun but instead cuts straight through the solar system on a one-way journey.

How common are biological extraterrestrial intelligences in the Milky Way? Host Simon Steel, Deputy Director of the Carl Sagan Center for Research, is joined by Manuel Scherf and Helmut Lammer to explore new research that challenges long-held assumptions about “Earth-like” planets and what it really takes for a world to support complex life.

👨🚀🚀 3... 2... 1... Liftoff!
Last night, Europe's new heavy-lift rocket, #Ariane6, successfully made its inaugural flight.
Ariane 6 can launch both heavy and light payloads to a wide range of orbits for applications such as Earth observation, telecommunication, meteorology, science and navigation.
It is a key step towards secure and autonomous 🇪🇺 access to #space.
Congratulations to the teams at European Space Agency, National Centre for Space Studies, Arianespace on this success!

#PPOD: NASA’s JWST provided the first vertical view of Uranus’s ionosphere in this image released on Feb. 19, 2026, revealing auroras shaped by its tilted magnetic field.
Getting a look at the structure of the region where the atmosphere interacts strongly with the planet’s magnetic field is giving us the most detailed portrait yet of where its auroras form, how the magnetic field influences them, and also data on how Uranus’s atmosphere has continued to cool since the 1990s.

Don't cross the streams!
All four 8 m units of ESO's Very Large Telescope are now equipped with lasers, as part of the GRAVITY+ upgrade of the VLT Interferometer.
These telescopes can work together as a gigantic "virtual" telescope. But combining their beams requires, among other things, bright reference stars, which are scarce. The lasers create artificial stars high up in the atmosphere, solving that problem.
