I nuovi risultati del telescopio Event Horizon tracciano il getto di M87 fino al suo buco nero

Le linee di base telescopiche ampliate, ancorate da ALMA, rivelano nuovi indizi su come il buco nero supermassiccio in M87 abbia lanciato un getto cosmico lungo 3.000 anni luce.

Un’immagine del Telescopio Spaziale Hubble della gigantesca galassia ellittica M87 con il suo getto simile a una fiamma ossidrica. La parte visibile di questo enorme flusso di particelle si estende per circa 3.000 anni luce.

📢🆕🚨 Using new data from the Event Horizon Telescope @‌ehtelescope, researchers have uncovered an important clue: they identified the most likely origin of the powerful outflow of matter (the jet) in the galaxy Messier 87 🌀.
🔭 The observations provide fascinating insights into the immediate surroundings of the extremely massive black hole 🕳️ at the center of the galaxy. Differences in the observed radio emission suggest that the jet forms very close to the black hole — in a region that had remained hidden in previous observations. Detailed modeling then allowed the position of the jet base to be narrowed down.
🕳️ Black holes themselves are invisible — but their surroundings reveal their secrets!

📢🆕🚨 Mit neuen Daten des Event Horizon Telescope @ehtelescope haben Forscherinnen und Forscher einen wichtigen Hinweis gefunden: Sie konnten den wahrscheinlichsten Ursprungsort des gewaltigen Materieausflusses (Jets) in der Galaxie Messier 87 🌀 bestimmen.
🔭 Die Beobachtungen geben spannende Einblicke in die unmittelbare Umgebung des extrem massereichen Schwarzen Lochs 🕳️ im Zentrum der Galaxie. Unterschiede in der gemessenen Radiostrahlung deuten darauf hin, dass sich der Jet sehr nahe am Schwarzen Loch bildet – und zwar in einem Bereich, der bei bisherigen Messungen unentdeckt geblieben war. Mithilfe detaillierter Modelle konnte schließlich die Position der Jet-Basis eingegrenzt werden.
🕳️Schwarze Löcher sind unsichtbar – aber ihre Umgebung verrät ihre Geheimnisse!

While we're on the subject of the horrifying scale of the Universe, I cannot get over what big fat bastard the SMBH at the centre of M87 is when compared to ours!

Size comparison of the two black holes imaged by the Event Horizon Telescope (EHT) Collaboration: M87*, at the heart of the galaxy Messier 87, and Sagittarius A* (Sgr A*), at the centre of the Milky Way. The image shows the scale of Sgr A* in comparison with both M87* and other elements of the Solar System such as the orbits of Pluto and Mercury. Also displayed is the Sun’s diameter and the current location of the Voyager 1 space probe, the furthest spacecraft from Earth. M87*, which lies 55 million light-years away, is one of the largest black holes known. While Sgr A*, 27 000 light-years away, has a mass roughly four million times the Sun’s mass, M87* is more than 1000 times more massive. Because of their relative distances from Earth, both black holes appear the same size in the sky.

🔭 Neue Einblicke beim Schwarzen Loch M87*

Wissenschaftler:innen des EHT-Netzwerks haben Bilder von 2017, 2018 und 2021 ausgewertet – und entdeckt: Die Magnetfelder in der Umgebung von M87* verändern sich deutlich über die Jahre.

Zum ersten Mal wurde auch die Basis des Jets, der aus dem Schwarzen Loch herausragt, sichtbar – durch verbesserte Technik und neue Teleskope.

++ Das Beste: Der Schattenring bleibt stabil – Einsteins Vorhersage hält. Doch wir sehen: Rundherum sind Turbulenzen 🔥

The infrared jet of #M87 observed with JWST: https://arxiv.org/abs/2507.18716 -> "We present the first JWST+NIRCam images of the giant elliptical active galaxy M87 and its jet at 0.90, 1.50, 2.77 and 3.56 µm. We analysed the large-scale jet structure, identifying prominent components, and determined the near-infrared spectral index."

In order to simultaneously visualise observations recorded with multiple filters, we obtained an RGB image of M87 using the F356W, F150W and F090W data mapped onto the red, green and blue channels, respectively.

Watching the Changing M87 Black Hole Event Horizon

https://fed.brid.gy/r/https://www.universetoday.com/170642/watching-the-changing-m87-black-hole-event-horizon/

<p>The event horizon is a fascinating part of a black hole’s anatomy. In 2017, telescopes around the world gathered data on the event horizon surrounding the supermassive black hole at the heart of M87. This was the first time we had ever seen an image of such a phenomenon. Since then, 120,000 more images of the region have been captured and, as astronomers sift through the data, their model of M87’s event horizon has evolved. </p>

<span id="more-170642"></span>

<p>Black holes, formed from the collapse of massive stars or in some cases through other processes, are regions of space-time where gravity is so intense that it warps the fabric of the universe. The event horizon is the boundary surrounding a black hole, beyond which nothing—not even light—can escape its gravitational pull. It marks the point of no return for any matter or radiation that gets too close. Within the event horizon, the curvature of space-time becomes infinite, leading to a singularity, a point where density and gravity reach extremes that modern physics and mathematics struggle to model. The event horizon’s properties are critical to understanding black holes, as it represents the outermost layer hiding everything within. </p>
