Astronomers sure do conjure up a lot of spooky images when they look out into deep space. A short Halloween thread:

Let's start with the Cosmic Bat Nebula (LDN 43). 🧪🔭

An important and deeply reported story from @joshdinner.bsky.social about the hollowing out of NASA, particularly its science centers, where some current employees now refer to "climate" only as "the c-word." www.space.com/space-explor...
NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say
"There is just a general acknowledgement that a lot of what is happening is illegal…"

This month, skywatchers will have the opportunity to observe not one but two once-in-a-lifetime comets.

Astronomy's Quanzhi Ye shared some tips on how to locate and view comets A6 (Lemmon) and R2 (SWAN) with @marinakoren.bsky.social for @nytimes.com ☄️ 🔭

We’ve got 2 good binocular comets this month. R2 SWAN is poised to pass 0.26 AU from the Earth on Oct 19th, while A6 Lemmon will put on its late October dusk encore performance, low to the west. Both could be Halloween sky treats if they hold up to expectations. www.universetoday.com/articles/new...

HiPOD: Frosty Sand Dunes of Mars

A field of sand dunes occupies this frosty 5-kilometer diameter crater in the high-latitudes of the northern plains of Mars. Some dunes appear to be climbing up the crater slope along a gully-like form.
