1/ ☄️ Comet C/2024 G3 (ATLAS) is gracing our skies, and we’d like to share some amazing images from ESO's Paranal Observatory in Chile!

This stunning shot by our friend Yuri Beletsky, with the comet next to an Auxiliary Telescope, is today's Astronomy Picture of the Day. Congrats, Yuri! 🔭 🧪

Every astronomer the first time they do reduce radio observations 🥴

ESOblog: New survey of exocomet belts is changing what we know about planetary systems New survey of exocomet belts is changing what we know about planetary systems

The Kuiper Belt contains the frozen leftovers of the formation of our Solar System. Using ALMA astronomers can observe similar belts around other stars, and they come in all shapes and sizes! What do they tell us about the formation of planetary systems?

The postdoctoral positions focus on:
- The dynamics of solids in debris discs as they interact w planets and flybys.
- The hydrodynamics of gas in debris discs.

The PhD positions focus on:
- The formation of debris/planetesimal discs in protoplanetary discs.
- Observations of gas in debris discs.

Two panels on the right show a before (top) and after (bottom) view of the surface of comet 67P as seen by the OSIRIS camera of Rosetta. The two images show that a large boulder (ca. 30 m) has moved by 140 m between May 2015 and Feb. 2016. The right panel shows a digital elevation model of that area and the two locations of the boulder. On the far right there is a 3D shape model of the comet showing the two lobes and the location of the boulder. Source: Fig. 1 in Tang et al.: https://arxiv.org/pdf/2411.17108

Can a 30 m boulder move by itself? The answer on comets seems to be yes! We've known for a while that a boulder on #comet 67P moved by about 140 m. We didn't know precisely when this happened and why. A new study might shed some light.
