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.

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

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":

Intriguing "hey, that's weird" discovery: Astronomers have found 14 asteroids that seeming move under their own power.

These objects are classified as "dark comets." Presumably they are emitting puffs of gas that shifts their orbits. But ...so far, nobody can spot any sign of activity.

The orbits of the fourteen currently known dark comets, Jupiter, and the Earth. One orbital period is shown for each object starting on the vernal equinox in 2023 March, and the points represent the corresponding initial positions of the Earth and of Jupiter. The left and right panels highlight the orbits of the outer and inner dark comets respectively. Orbits of the newly discovered dark comets are labeled with italicized font, and the orbits of previously reported objects are labeled in roman font.

An extremely detailed diagram of the history of Science Fiction. The diagram has a rather monstrous aspect, with tentacle-like roots and branches. On the upper left corner are found the roots of the diagram: Fear and Wonder, giving way to Animism and Legend. Other portals into the diagram are Philosophy, Art, Exploration and Observation. These roots converge and possibly interact with other concepts such as the Enlightment, Science, Utopias, Romantic Movements. Important science fiction works, authors and genres emerge on the way, amidst a vast quantity of other entries: the Gothic Novel, Frankenstein, Jules Vernes, H.G. Wells, Edgar Allan Poe, Science Adventure, Fantasy Adventure, Alice in Wonderland, Weird Tales, Pulp Magazines, Astounding Science Fiction, Galaxy Magazine, H.P. Lovecraft, Sword+Sorcery, Modern Horrror, Isaac Asimov, Philip K. Dick, Dune, Space Opera, Cyber Punk, Star Wars, Alien, Terminator, 2001 Space Odissey, Star Trek, Battlestar Galactica, Total Recall, J.R.R. Tolkien, Dracula, Metropolis, King Kong, Aldous Huxley, and so on. A timeline is indicated on the upper and lower boundaries of the diagram.

The coolest thing about mapping the universe in gravitational waves? You need a telescope the size of our galaxy to do it.

So...astronomers got to work & figured out how to make a telescope the size of our galaxy.

Astronomers are closing in on a radically new kind of cosmic map--a map that shows the universe in gravitational waves.

The process is hard. This new, preliminary version is uncertain. But we're seeing a fresh view of reality come into focus.

This map, which measures the directional power of the gravitational wave signal, reveals some intriguing results. Astrophysicists generally expect the gravitational wave signal to be approximately the same in all directions. This arises from key cosmological assumptions that the Universe is homogeneous and isotropic, generally evenly distributed in all directions and evenly mixed. Surprisingly our map shows a ‘hot spot’ - an area of stronger gravitational wave signal in the Southern Hemisphere. This hot spot could suggest that a nearby, extraordinarily massive black hole binary is drowning out others, but it may also just be a statistical anomaly.
