real

(damn I wish I could find the actual email where I submitted the proposal. I probably sent it through my now-deleted elementary school district email or through a web form on the MPC website, which could the reason why it's lost now)

if you don't believe me, i don't blame you lol

i'm not gonna defend it

I named an asteroid after Cary Huang (that guy from @jacknjellify.bsky.social)

all I did was write the name proposal and email it to the IAU WGSBN back in February 2021 cause I was bored during COVID lockdown. It got accepted in June 2021 somehow

YouTube video by JayChoken The Weird Worlds of Gliese 876

Hi yall! Please check out JayChoken, he's a super underrated worldbuilding Youtuber who makes videos about exoplanets! :D

He's approachable, straight to the point, & shows his analysis of sources with proper visuals, unlike most astro Youtubers. No drama-doc BS here! www.youtube.com/watch?v=5G7P...

sorry for the even more belated response..
but yes, you can predict/estimate how much moons above a certain radius exist! A 2021 study did that and previously predicted that Saturn should have 150±30 outer moons larger than 1.4 km radius (more moons than Jupiter) iopscience.iop.org/article/10.3...

i see this as an absolute win :3

Some stuff I did for the first 3 days of @morgandenman.bsky.social's #SpacetoberChallenge! Been too busy with college so I can't do these on time blehhhh

(I'll post these individually later)

(update)
This teeny meter-wide asteroid C15KM95 was officially announced with the new name "2025 TF" today! minorplanetcenter.net/mpec/K25/K25...

(and a neat photo of the asteroid by @filipp-romanov.bsky.social over at: bsky.app/profile/fili...)

Now to wait an hour until this gets on Wikipedia...

nyoooom

A moderate bright point-source in the middle and smaller sources around them, labeled with dates.

Dwarf Planet #Quaoar and its moon #Weywot with #Hubble WFC3/UVIS filter F350LP. Quaoar is located in the Kuiper Belt (beyond planet Neptune).

I combined different epochs and oriented them with north being up. I removed stars. The moon changed position during its orbit around the #DwarfPlanet.

My new color photographic map of Pluto is now online.

🧵 1/5

More attention, views, & clicks = more ego and money (ad revenue i guess?)

I only look for astro news from places that I know are reliable (phys.org, arxiv, anton petrov, space.com, etc.), so idk what weird stuff ppl are saying elsewhere. From experience, reddit and tiktok are absolute garbage lmao

ooooo hypeeee!!

yeah... genuinely sad that there's actual fearmongering. Personally I find 3I/ATLAS super fricking awesome!

(tho not as weird as the nitrogen & carbon monoxide-rich blue comet C/2016 R2 and the explodey comet 29P/Schwassmann-Wachmann... I've been hyperfixating on these two and THEYRE SO WEIRDDD)

As one of the people (who had been) actively updating the 3I/ATLAS Wikipedia article, thanks! :D

Mike Kelley describes spectra of the icy surface of comet Hale-Bopp, taken at a distance of 46 AU (!!) with JWST 🔭 : similar to Water-type TNOs but with organic features

heck yeah Makemake getting that makeover from JWST!
So now we have evidence of geochemical activity, a cryovolcanic hotspot, and a potential atmosphere.

I swear if Makemake turns out to also have rings or a second moon, it's gonna become my 4th favorite dwarf planet

Mimas science is serious business

Lucy image of asteroid Donaldjohanson, with features labeled with their formal names approved by the IAU

A screenshot of the IAU's announcement of 11 new names for Donaldjohanson's surface+shape features. The text reads: 11 Names Approved for (52246) Donaldjohanson: Afar Lobus, Olduvai Lobus, Hadar Regio, Minatogawa Regio, Luzia Dorsum, Boxgrove Saxum, Kennewick Saxum, Cashel Saxum, Mungo, Narmada, and Windover Collum 08/27/2025 The IAU Working Group for Planetary System Nomenclature has approved the names Afar Lobus, Olduvai Lobus, Hadar Regio, Minatogawa Regio, Luzia Dorsum, Boxgrove Saxum, Mungo, Narmada, Kennewick Saxum, Cashel Saxum, and Windover Collum for eleven features on the asteroid (52246) Donaldjohanson. For more information, please see the Donaldjohanson nomenclature map in the Gazetteer of Planetary Nomenclature.

The IAU announced official names for Donaldjohanson's surface & shape features 2 weeks ago, but nobody has mentioned the news. They're all named after archeological sites and hominin fossils, which is fun and awesome haha

(Afar Lobus = small lobe, Olduvai Lobus = big lobe, Windover Collum = neck)

Today on arXiv: The recent JWST TRAPPIST-1 e papers.

They are somehow not even the biggest news in the list. Today's arXiv day's absolutely stacked.

bwehh i haven't gotten to reading it yet lol

frickkkkkkkk

ikr holy crap, the Makemake papers are insane (though I already knew about the Makemake moon orbit beforehand, I've been talking with the author about this)

this is a continuation of this btw bsky.app/profile/astr...

(also how long will it take before someone makes a chimichanga joke lol)

(Name announcement in link)

There's an interesting pattern where the new name initials (except Chimini) match the letters of their designation (e.g. Rumina = RM43); IAU says it's intentional.

So this leaves 2017 OF201 and 2021 DR15 as the biggest unnamed Solar System objects at ~700 km diameter...
