These two views of Saturn moon Titan show the southern polar vortex, a huge, swirling cloud that was first observed by NASA Cassini spacecraft in 2012.

Close view of southern polar part of the Moon. The big crater enjoying local sunrise is Clavius.
The distinctive one with the illuminated central peak just to the left and below it is Tycho. That is the bright one with the visible rays that circle the Moon when she is full.
The dark basin on the left is Mare Tranquilitatis, known from such Apollos as 11 🦅
NEAF 2026 Day 1
I Flew Across The World For This Astronomy Event
Two days at North Eastern Astronomy Forum and I gave myself one rule:
Talk to as many vendors as possible before my brain taps out.
First time at NEAF, flew halfway across the planet, walked in… instant overload. Gear I’ve only ever seen online, people I’ve only ever spoken to through a screen, now all in one room.
So I just started walking and talking.
Vendor after vendor, no plan, just conversations. Learning, questioning, and trying not to convince myself I need everything I see.
Also had a few “wait… you’re AstroPuNk?” moments which I was not prepared for at all.
This is day one. First impressions, first chaos, first look at how big this world actually is when you step into it.
Full video up now.

Versus the UV/IR cut eye, no-filter eye, Hydrogen/Oxygen eye and Sulphur/ Oxygen eye. The former two are 1ms exposures, the latter two 0.1s. The IR was 0.02s.
I spy with my giant infrared eye something starting with M. Right now.
More 2025 editing backlog! Sh2-132 the Lion Nebula from Bortle 9 Berwyn. 26 Hrs captured over 8 clear nights last fall. More details in Astrobin, Telescopius. Thanks for looking, Clear Skies!

Pluto Hulk-like Moon Charon: A Possible Ancient Ocean?
Images from NASA New Horizons mission suggest that Pluto largest moon, Charon, once had a subsurface ocean that has long since frozen and expanded, pushing out on the moon surface.
