I might incur 13.7 days of bad luck for sharing a non-TESS light curve on #TESStuesday but this multi-band light curve from the brand new Vera C. Rubin Observatory's commissioning data is too good.
This is a distant (16.6kpc), faint (18th magnitude) SX Phe variable but the light curve has the unmistakable shape (in the optical g band) of a δ Sct/SX Phe variable.

On Dust Devil Diameters, Occurrence Rates, and Activity
"Where a typical terrestrial dust devil might span several to ten meters in diameter and hundreds of meters in height, Martian dust devil could be hundreds of meters across and kilometers tall."

@arXiv_astrophGA_bot I feel that the Sol System's usual position in the quiet suburbs of the Galaxy may be a reason for this 'Rare Earth'
Bobbling along dangerously close to a star forming region isn't good for our health.

VLT timelapse of 3I/ATLAS, a new interstellar object
In this video, 3I/ATLAS is seen moving to the right over the course of about 13 minutes. These data were obtained with the FORS2 instrument on the VLT on the night of 3 July 2025, just two days after the comet was first discovered. At the end of the video, we see all frames stacked into a single image: the deepest and best to date we have of this foreign object.

#paperday (submitted to A&A) on #astroph:
"On the interpretation of XRISM X-ray measurements of turbulence in the intracluster medium: a comparison with cosmological simulations" by myself and G. Brunetti.
https://arxiv.org/abs/2507.04727
It's short reaction paper to the latest (cool) XRISM measurements of gas motions in the Coma cluster (and others), which were interpreted as evidence of weak and much-steeper-than-Kolomogorov turbulence.
We think this is wrong..
