Last night, SARA_Obs Chile: Didymos/Dimorphos dust trails. 7x5m tracked on asteroids, stars filtered. WNW trail extends to 165", projecting to ~8600 km. (0410-0500 UT 30 Sept., ~78 hours after impact, R band)

Congratulations to Dr William Dunn Dr William Dunn UCL Mathematical & Physical Sciences on being awarded the 2022 Henry Moseley Medal and Prize by the Institute of Physics Institute of Physics for his discoveries around the X-ray emissions of Jupiter and Uranus ucl.ac.uk/news/2022/oct/…

Couple of quick shots of the #Eclipse2022 ... one through trees (and passing aircraft), and one with sunspots

#Mars occulted by the Moon - quick sequence from one of UCL Observatory's robotic telescopes (0.1-sec in H-alpha filter) #marsoccultation UCL Mathematical & Physical Sciences Giorgio Savini

A movie of planet #Mars disappearing behind the moon, sped up 8x. Imaged from Guildford, UK. #Moon #Occultation #Astronomy #Astrophotography #Space

Better process of Mars and the Moon from this morning (04:57:57 UT to be precise!)

Track of C/2022 E3 (ZTF) 4-19 Feb, showing the comet's encounters with Capella, the Kids asterism, Hassaleh (Iota Aurigae), Mars, the Hyades and Aldebaran. Main tick marks are for 00:00 UT on the date shown, smaller ones at 6 hourly intervals.

Fantastic! Remnants of the #SAR2667 fireball have been retrieved in France by an 18-yr old student.

Happy JD+2460000 everyone! en.wikipedia.org/wiki/Julian_day

Neutron star black hole merger klaxon! 💥 gcn.nasa.gov/circulars/33813

Breaking my Twitter moratorium to make sure astronomers are aware there is a new supernova in M101 at 7 Mpc. It is a core collapse supernova caught very young, at 14.9 mag. Supernovae this close only come around once a decade, so get on it! wis-tns.org/object/2023ixf…

preposterous proposition or plausible possibility? arxiv.org/abs/2305.13400

Allow me to share three great events at #cheltscifest this year. First, THE MOST AUDACIOUS TELESCOPE IN HISTORY with Richard Ellis and Hannah Wakeford - all about JWST and its astounding technology and discoveries cheltenhamfestivals.com/science/whats-… 1/3

Starlifting - how make stars like the Sun live billions of years longer. Now with full MESA evolutionary tracks! arxiv.org/pdf/2210.02338…

In eight new papers, NANOGrav PFC presents evidence for a gravitational wave background. In this bite, we provide an overview of their results and their implications #pulsartimingarrays #GravitationalWaves astrobites.org/2023/06/28/dro…

For the first time, here is our galaxy seen in the "light" of neutrinos. A remarkable achievement by the team at IceCube Neutrino Observatory. icecube.wisc.edu/news/press-rel…
