This weekend, the International Space Station marks a quarter-century of continuous occupancy.

"By NASA’s count, 290 people from 26 countries have visited the space station. Seven are up there right now, representing the U.S., Russia and Japan."

A particularly weird one: The Flying Bat Nebula has the Squid Nebula inside of it.

Is the bat carrying a squid? Did it swallow a squid whole? Somebody needs to work out the mythology here.

Nebula Photos - Sh2-129, OU4, Flying Bat Nebula and Squid Nebula

The red (Ha Signal) is sh2-129, the flying bat nebula. The blue squid nebula (OIII signal) in this image (OU4) was discovered by the French Amateur Astrophotographer Nicolas Outters in 2011. It is very faint. I used a tone mapping process originally described by J-P Metsavainio to bring it out. All the data was collected on my summer road trip to see the total eclipse of the sun.

Finally, there's this iconic image from JWST. Sure, they can call it the "Pillars of Creation," but this is obviously a giant Monkey's Paw that has already curled two fingers.

Pillars of Creation (NIRCam and MIRI Composite Image)

Pillars of Creation (NIRCam and MIRI Composite Image)
By combining images of the iconic Pillars of Creation from two cameras aboard the NASA/ESA/CSA James Webb Space Telescope, the Universe has been framed in its infrared glory. Webb’s near-infrared image was fused with its mid-infrared image, setting this star-forming region ablaze with new details.

Myriad stars are spread throughout the scene. The stars primarily show up in near-infrared light, marking a contribution of Webb’s Near-Infrared Camera (NIRCam). Near-infrared light also reveals thousands of newly formed stars – look for bright orange spheres that lie just outside the dusty pillars.

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).

https://apod.nasa.gov/apod/ap241027.html #space #science #art #halloween

APOD: 2024 October 27 – LDN 43: The Cosmic Bat Nebula

A different astronomy and space science related image is featured each day, along with a brief explanation.
What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars.

Here's some of the X-20 Dyna-Soar material I received to use as reference for the model. I really like the diagrams, the shallow cargo bay was a surprise to me.

Spectacular time-lapse image of Comet Lemmon (C/2025 A6), taken by astrophotographer Michael Jäger.

There might have been, um, a few satellites passing by during the long exposure.

Hiti

हिति , in Nepāl Bhāṣā, is the word for a shared community water tap. Even in modern Newar cities, these ancient structures still pour out fresh mountain water piped through ancient underground filters and conduits. They are a place to wash, to talk, to drink, to meet the locals: a nourishing, refreshing social-ecological place.
