The Korean lunar orbiter Danuri succeeded in capturing the total eclipse observed on the European continent on the 12th (local time). The part of the shadow that touches the surface of the moon (top left) is a total solar eclipse. /Photo: Korea Aerospace Research Institute

There's a missing rung on the academic career ladder in Austria and Germany. Historically there wasn't a position like assistant professor or lecturer, so the jump from postdoc to professor was — and mostly still is — huge. Between 70% and 80% of academics in Austria don't have permanent jobs.

We are used to seeing weird shapes of small asteroids, but this is next level! look at the shape of 44 Nysa from Minker et al. This is 75 km volume-equivalent diameter object! Also it has a satellite! #planetSci 🧪

Residuals of R-band images of the Nysa system on 2026-
02-15 after processing with the blind deconvolution method of
Appendix A.3. The position of the satellite is marked with a pink
arrow. To improve the S/N, the deconvolution residuals were av-
eraged with a a ±5 frame sliding window. To provide scale, the
primary has been superimposed. An extended video version of
this figure and the same processing for the 2026-03-21 dataset is
available online.

Our latest paper has been accepted for publication! 🎉 We demonstrated that a single late infall event perturbing the outer disk can trigger the formation of multiple giant planets and ringed disk structures resembling those observed around young stars. Paper: arxiv.org/abs/2607.18370

Figure from the paper with two rows and four columns. The upper row shows the results of the dust evolution and planet formation model. The bottom row shows synthetic observations of these snapshots. The model starts with single dust ring caused by late infall at around 80 au. In the next snapshot at 0.75 Myr, one giant planet formed and split the initial ring in two. At 1.05 Myr the planet has migrated inward, and a new planet emerged around the location of the original ring. This evolution continues, and at 1.7 Myr we have 3 giant planets at around 16 au, 23 au, and 40 au, and 3 dust rings, each located just inside of a planet.
