A bit of a different take on the amazing Artemis II launch footage. Here I stitched clips from the four Solar Array Wing Cameras to make this panoramic video. This is during the later part of the Core Stage burn until MECO and stage separation, sped up to 10x. 🔭🧪 #Artemis

David Hogg has written a white paper on doing astrophysics in the age of LLMs. It looks to be thought-provoking. My initial reaction is that either LLMs will destroy the field or they will force a reckoning with and re-imagining of the current system that often prioritizes output over quality. 🧪

Not all rings are forged in fantasy, my precious!  For astronomers, they are found in space. This image shows debris discs captured by ALMA around stars. The two at the top-right told astronomers something very interesting. Find out what here: www.eso.org/public/images/potw2603a 🔭 🧪
A 5x6 array of astronomical images of debris discs, shaped like rings. Some are thin rings, others are wider and have gaps within them. Some of the discs are face-on and others more inclined. Most of the discs are orange except those on the rightmost column which are blue.

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. 🧵 1/3 #planetaryScience #SciComm 🧪⚛️
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.
