G’day there! I’m Ben, and this is my about… 19th social media #introduction post? I’m a #photography and #science nerd, and the victim of perennial curiosity.

I’m an #actuallyautistic #disabledartist, living in lutruwita/Tasmania, #australia, in my mid 30s. I specialise in #landscapephotography, #astrophotography, and #timelapse in the island’s wild places.

I like to play with light. These are some of my more successful experiments.

How are we all? Say hello!

Under certain spectrums of light, living and organic matter can produce intensely vibrant colours, glowing as if by magic. This process is called biofluoresence. Here, the Milky Way’s galactic core rises behind a small oceanic lake on Queensland’s coast.

During the autumn months, Tasmania sees a brief explosion of a short-lived bioluminescent fungus, the so-called Ghost fungus (Omphalotus nidiformis) in secluded damp forest patches affixed to rotting trees. Owing to their typical low position hidden underneath forest canopies, a view out to the night sky is very rarely afforded, much less on clear nights – making this view out to the crown jewel of the night sky, the galactic centre of the Milky Way, a truly once in a lifetime opportunity.

Tasmania’s Low Head is home to one of the most important lighthouse arrays. Sitting at the mouth of kanamaluka/River Tamar, it serves as herald of land for sailors arriving across the Bass Strait. Occasionally it plays host to the southern aurora and the setting Milky Way, captured with grasses and rocks fluorescing strongly in the foreground.

Remembering another notable date in history: 100 years ago this month, Edwin Hubble proved that our galaxy is just one small island in a vast cosmic sea.

Our awareness of galaxies is just one century old! I dig into the full story in my latest Invisible Universe column:

https://invisibleuniverse.substack.com/p/the-100th-birthday-of-the-universe #space #science #astronomy #history

Edwin Hubble’s glass photographic plate H335H, obtained with the 100-inch Hooker Telescope Oct. 5/6, 1923, shows the galaxy M31. Three “new” stars are marked in black with the letter N. However, Hubble later noted that the star at the top right was present on earlier plates but fluctuated in brightness. He subsequently crossed out the N and marked it with “VAR!” in red. This is the Cepheid variable M31-V1, which Hubble used to calculate the distance to M31 and solve the mystery of the spiral nebulae.

@orionkidder : if recollection serves me, this article will be of interest re one of your SF universes.

A sweet astronomy story, for a little break:

Earth & its Moon were forged from a violent collision. But Pluto and its giant moon, Charon, came together with a gentle kiss. A similarly soft process may have occurred all across the outer solar system.

Newly discovered: A pair of supermassive black holes (40 million times as massive as the Sun) cuddling in a distant galaxy.

"Cuddling" in this case means they're about as far apart as Voyager 1 is from Earth...which is really close for such monster objects.

https://science.nasa.gov/missions/swift/nasas-swift-studies-gas-churning-monster-black-holes/ #science #space #astronomy

Watch as a gas cloud encounters two supermassive black holes in this simulation. The complex interplay of gravitational and frictional forces causes the cloud to condense and heat. Some of the gas is ejected from the system with each orbit of the black holes.

Well, this is fascinating! The city of Poznan, Poland uses eight clams to control their water supply. When the water is clean, they remain open, but close when contaminated, closing a sensor harmlessly glued to their shell. Computers do the rest. After three months, the clams are returned to their original home and replaced with new clams. #science #health #cleverhttps://kottke.org/24/12/eight-clams-control-this-polish-citys-water-supply

Okay, it's #introductions time! Hi 👋

I'm Badri, a #writer and #nonfiction#editor at Snipette looking to explore and highlight the interesting aspects of our world 🔦

I also #read a lot, and am always on the lookout for interesting bits of #science, #culture, #history, or #philosophy which come out at some point or other in my articles 👀

I'm also @badrihippo, but this instance, Snipetteville, is a place for all Snipette editors to hang out. We may be talking in private, but if you see a public conversation you're most welcome to join. Feel free to tag me in deep and/or lighthearted #philosophical conversations about aspects of the world 💭

(If you want to write for Snipette, DM me now!)

Wowzer! Map of cosmic flows, by yours truly, makes it to the cover of the Nature Astronomy journal.

"Galaxies from
wherever flock
together"

I'm no poet, but could this be a Haiku?

A cover of the Nature Astronomy journal, dated December 2024, Volume 8, issue number 12, featuring a three-dimensional visualization of the cosmic velocity field inferred from the Cosmicflows-4 catalog of galaxies' distances and velocities. This map spans two billion lightyears from top to bottom. The velocity field is mapped by means of tens of thousands of very thin streamlines, seeded at the positions of the catalog's galaxies. Streamlines are shown white and semi-transparent, against a black background. They exhibit a very complex pattern with multiple attractors, seen as points of convergence of the lines. A text reads Galaxies from wherever flock together.

For some reason, the NASA folks did not link to the research paper describing the newfound dark comets.

Allow me to correct that oversight. Here is "Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes":
