Yes, ish. Impacts are, at best, an ad hoc explanation for planetary mysteries, the last resort of the damned.

Hi! I’m a planetary astronomer studying asteroids, involved in groundbased, JWST and spacecraft measurements of them. I was Investigation Lead for the #DARTMission, NASA’s first planetary defense test mission.
I also have a Starter Pack of other planetary scientists! 🧪🔭🛰️

Lots of folks are joining BlueSky today!
Scientists of BlueSky, introduce yourselves and what you work on so new folks can follow you!
I’m David, I’m a marine biologist and author who studies ocean conservation, especially sharks, endangered species, and sustainable fisheries!

We would expect the 2026 record to exceed the 2023 record by about 0.1C given the current planetary warming rate of ~0.3C/decade. We will see if that happens.
The global surface temperature anomaly has now tied the record (1.15C above 1991-2020 baseline) set on Nov 17 2023:

We now have two large planetary missions that are not based upon the science priorities established in the decadal surveys.

“Our fragile fossil fuel-based economy leaves us exposed to volatility and conflict, making an urgent, accelerated transition to renewable energy essential for both economic stability and planetary survival”
I discuss why #BAAJA is a problematic fossil fuel trojan horse in this new commentary for @thebulletin.org: thebulletin.org/2026/11/demo...
Democrats stayed quiet on climate. Now it's time to act
The climate crisis is an affordability issue.

If you write out the basic facts of trees, but framed as technology, it sounds like impossible sci-fi nonsense. Self-replicating, solar-powered machines that synthesize carbon dioxide and rainwater into oxygen and sturdy building materials on a planetary scale.

Astronomers spot white dwarf star with two rings of planetary debris
Billions of years from now, the sun is expected to run out of fuel and greatly expand into what is called a red giant, eventually shedding its outer layers and leaving behind its dense core, a white dwarf. Some of the planets in our solar system would be destroyed while others might survive.

making fossil fuel extraction more efficient during a planetary wide climate catastrophe is the delusional pursuit of godlike machine intelligence by another name
‘Cohere’s founders offer an answer that may disappoint Silicon Valley: The pursuit of godlike superintelligence is probably futile, so better to make money now by keeping AI costs low with models just smart enough for whatever its business clients need.’ www.bloomberg.com/news/article...
AI’s Newest Billionaires Want No Part of Superintelligence Race
The race to build ever more powerful artificial intelligence has created a new class of billionaires. Some of them are starting to question the race itself.

I used drones to record the performances that were overlapping or scheduled against each other. They were all being recorded for the local planetary entertainment feed, and the popular ones would be reconfigured as video productions

Hi! 👋
I’m Caitlin! I have a doctorate in planetary science, mainly work on planetary materials science, different space volcanoes, Moon ice adventures, civil engineering on the Moon and Mars, and a dash of space policy!
Oh! And LOTS of science outreach!

Closing in on Didymos. ☄️
Our planetary defence mission Hera has captured its first close-up of the binary asteroid system, 60 km away, as it prepares to investigate the aftermath of DART’s historic impact with Dimorphos.
Detailed images of both asteroids are coming on 25 November.
