Paper day! It's not easy to fit all the science presented at a meeting as big as ACM in the word limit of a short report, but hey, we gave it a go! You can find the Nature Astronomy Meeting Report on Asteroids Comets Meteors 2026 here: rdcu.be/MvrGvwmXQsXa 🔭☄️🪨

In reporting this, I learned that Russia launched a big space mirror in the 90s. Retrospective pieces c. 2015 were like "what a crazy, supervillain-y idea!" Now the idea is back, being taken seriously, and shining light (sorry) on the shortcomings of space law. 🔭🧪 www.sciencenews.org/article/refl...

Big space mirrors could bring Earth on-demand light — and upend our night sky

A space satellite that would offer light on demand has astronomers asking: Who controls the night sky?

Great to read BBC Sky At NIght interview with Cyrielle Opitom (@physicsastronomyed.bsky.social) on why comet 3I/ATLAS is a big deal. There's also a nod to how @vrubinobs.bsky.social can help us better understand interstellar objects 🔭 www.skyatnightmagazine.com/news/3i-atla...

There's nothing cooler than Astronomy with preschoolers 🙂 The group at Carrots and Peas nursery in Poznań was very enthusiastically studying the ejecta made by throwing rocks at trays filled with layers of flour and cocoa... planetary defenders in training! 🥰 🪨🛰

I’ve been exploring gravitational reaccumulation after asteroid catastrophic disruptions and am finding contact binaries are super common outcomes! I can’t help but notice how similar Torifune looks compared to this fragment from one of my simulations, which I will present tomorrow at #ACM2026

Andy Rivkin@asrivkin.bsky.social · 3mo ago

Torifune!! It looks like another Itokawa! As JB says, it’s a great time for asteroid studies, and hopefully we’ll hear a lot more over the course of the #ACM2026 meeting!

Astronomy needs dark, quiet skies, but light and radio pollution from growing space activity is putting them at risk. 🛰️ The Group of Friends for Dark and Quiet Skies has created a survey to help inform international discussions on protecting our Dark and Quiet Skies - and wants to hear from you. ⤵️

Reflect Orbital aims to launch 50,000 mirror-like satellites to provide sunlight at night, with reflected beams spanning at least 5 km on Earth's surface. This image illustrates how scattered sunlight would increase the overall brightness of the sky above the VLT. 🔭 🧪 ☄️ #DarkSkies 3/4

Two circles shows the night sky view from ESO's Very Large Telescope. The left image was captured with an all-sky camera on a moonless night. The image to the right is a simulation showing how much brighter the sky would be with Reflect Orbital’s full constellation of 50 000 mirrors. Even though the mirrors are not pointing directly at the observatory, they still diffuse light sideways, which is then further scattered by the atmosphere. The sky would be up to three to four times brighter.

Along with LSST start 🎉 also out today is Thiele et al. reporting the CRASH Clock is at 2.5 days 👀 That's how long it'd take for satellites to start crashing into each other if they lost maneuvering capability 🛰️ When the authors first shared on arXiv in June 2025, it was at 5.5 days… Seems fine 🔭

A new CRASH Clock measures the chance of satellite collisions, and it’s ticking down fast

How prepared are we for a solar storm, bad software update or cybersecurity event that could trigger widespread loss of satellite control?

For absolutely NO REASON WHATSOEVER, I thought I'd mention my 15-year old paper on orbital similarity: academic.oup.com/mnras/articl... Other publications on orbital similarity available. There really is no need to eyeball orbital similarity.

Orbital similarity functions – application to asteroid pairs

Abstract. The paper expands the idea of Vokrouhlický and Nesvorný who used a modified Zappalà et al. metric with osculating elements in search for pairs of
