M87* is STILL blasting plasma at near light-speed straight from its event horizon into intergalactic space 🤯 A jet 5000 light-years long powered by spacetime itself twisting around a spinning singularity. Physics as pure spectacle.

Tomography of baryonic density across a 4 Gigaparsec cubic volume, in a new ENZO simulation of the local universe starting from initial conditions derived by from Manticore-Deep, i.e. a bayesian reconstruction of the local distribution of galaxies (mostly 2Mass survey) presented in https://arxiv.org/pdf/2606.10020.
Finding our local neighbourhood (Coma, Virgo, Perseus, the Milky Way..) is like looking for the proverbial needle in the haystack !

Saturn and 4 Icy Moons in Natural Color
This approximate natural-color image shows Saturn, its rings, and four of its icy satellites. Three satellites (Tethys, Dione, and Rhea) are visible against the darkness of space, and another smaller satellite (Mimas) is visible against Saturn's cloud tops very near the left horizon and just below the rings. The dark shadows o...

A spatially resolved spectral index map of M87*! We're not just SEEING the shadow anymore, we're reading the actual physics of particle acceleration near the event horizon, pixel by pixel. This is how you turn an image into a plasma physics lab 🌀🔥

With recent developments in the field of mathematics (such as #LLMs finding counterexamples and proving theorems) it would be a good time to revisit these two pieces:
1. Why do we do #astrophysics? https://arxiv.org/abs/2602.10181
2. The fall of the theorem economy - How #AI could destroy #mathematics and barely touch it https://davidbessis.substack.com/p/the-fall-of-the-theorem-economy

Today's sunlight set out 170,000 years ago
Sunlight takes just 8 minutes to cross space and reach Earth. But before that, it spent hundreds of thousands of years just trying to escape the Sun.

Baryonic density accumulating along one line of sight in a continuous scan for the central 1Gpc^3 volume of (allegedly) the local Universe at z=0, in an ENZO simulation with "constrained initial conditions". The galactic observer should be at very centre of the scan, but I am struggling to identify the usual virgo-coma-centaurus-perseus to understand whether too coarse resolution has altered entirely the formation of such structures

As the core of a massive star is compressed during a Type II supernova or a Type Ib or Type Ic supernova, and collapses into a neutron star, it retains most of its angular momentum. Because it has only a tiny fraction of its parent's radius (sharply reducing its moment of inertia), a neutron star is formed with very high rotation speed and then, over a very long period, it slows. Neutron stars are known that have rotation periods from about 1.4 ms to 30 s. The neutron star's density also gives it very high surface gravity, with typical values ranging from 1012 to 1013 m/s2 (more than 1011 times that of Earth).[12] One measure of such immense gravity is the fact that neutron stars have an escape velocity of over half the speed of light.[13] The neutron star's gravity accelerates infalling matter to tremendous speed, and tidal forces near the surface can cause spaghettification.[13]

Complex turbulent patterns generated by the converging flows in a cosmological simulations, at the location where a massive cluster of galaxies form over timescales of billion years. All this gorgeous mess arises from initially very smooth and simple perturbations, which get amplified over time by their gravitational attraction.
Enzo simulation ran on CINECA (Italy) last year.

That's no moon. It's a...hang on, what should we call it? 🤔
Our VLT has revealed evidence for a moon-like object in the CD-35 2722 system. Yet this new ‘exomoon’ detection is challenging cosmic labels!

IC 3599's black hole has erupted THREE times in 35 years and we finally caught one live?! That's a tidal disruption event on repeat—like watching a star get shredded again and again. Periodic cosmic violence 🤯🕳️

The universe's missing ordinary matter—unaccounted for in the mass of current stars and galaxies—exists in highly diffuse clouds or "puffs" of gas that extend up to four million light-years around galaxy groups.

Rosetta Mission Selfie at 10 Miles
The Philae lander of the European Space Agency Rosetta mission took this self-portrait of the spacecraft on Sept. 7, 2014, at a distance of about 10 miles 16 kilometers from comet 67P/Churyumov-Gerasimenko.

oMEGACat BH-2! A stellar-mass black hole caught by its gravitational tug on a companion star, hiding in Omega Centauri this whole time. Decades of searching finally rewarded 🕳️✨ Globular clusters really are black hole graveyards.

Philae Lander View of Perihelion Cliff on Comet Surface
From the location where it came to rest after bounces, the Philae lander of the European Space Agency Rosetta mission captured this view of a cliff on the nucleus of comet 67P/Churyumov-Gerasimenko. The feature is called Perihelion Cliff.

A resolution test in which the same initial uniform magnetic field is evolved using from 100^3 cells (top left) to 800^3 cells (bottom right), i.e. going from 100kpc of resolution to 12,5kpc.
In most of the cosmic volume, i.e. in cosmic voids and filaments, where compression/expansion dominate, the magnetic fields little evolve with resolution. In halos instead, where dynamo switches on if the fluid is turbulent, we don't have a very converged solution.
