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.

They're gonna get people killed and in so doing also poison the public's view of #SpaceExploration, all because they cannot be bothered to buy an mf-ing generator or something that a f-ing 8th grader could sort out.

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.

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.

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.

https://www.spaceaustralia.com/feature/mapping-gravitational-wave-universe #space #science #astronomy #nature

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 โ€˜hot spotโ€™ - 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.
