Take off to the bright orange star Betelgeuse 🚀🌟

The star underwent an unprecedented dimming in late 2019 and early 2020. Observations later revealed that it was caused by a dusty veil shading the star, due to a drop in temperature on the star's surface.

Join us on a trip to the dwarf star PDS 70, located 400 light-years away and with at least two planets orbiting it.

The final shot shows an ALMA image of the PDS 70 system, where a moon-forming disc is visible around planet PDS 70c.

Take a glimpse into APEX, located in Chile’s Atacama Desert 📡👀

Once a joint project of the Max-Planck Institute for Radio Astronomy (MPIfR), the Onsala Space Observatory and ESO, APEX now becomes a project solely of the MPIfR.

This animation takes us to a Wolf–Rayet star in NGP–190387, a galaxy so far away its light took over 12 billion years to reach us.

Wolf–Rayet stars are hot and massive, and are thought to end in dramatic supernova explosions.

Enjoy this trip to NGC 1850, a cluster of stars in the Large Magellanic Cloud.

This cluster harbours the first small black hole outside of our galaxy to be discovered by looking at its gravitational influence on the path of the star orbiting it
