**A stellar-mass black hole in a binary with a massive star launches two jets; one points almost at Earth. Radio maps show a structure extending one hundred light-years.**

A possible microblazar has been identified in the Milky Way, according to catracalivre.com.br. The system lies about twelve thousand light-years from Earth and combines a massive star with a compact object, a stellar-mass black hole [1]. The study was led by Josep Martí and published in the journal Astronomy & Astrophysics [1].

The black hole continuously draws in material from the neighbouring star. Under these extreme conditions it launches highly energetic beams that cross great distances within the galaxy [1]. The publication describes this as one of the most violent manifestations of relativistic jets observed by astronomers.

## Two jets, one pointed at Earth

The black hole expels two streams of matter in opposite directions. Each reaches about seventy-five percent of the speed of light [1]. One of them points almost directly toward Earth. Because of the relativistic Doppler effect, its emission appears considerably amplified to instruments on the planet's surface [1].

The opposite jet remains practically hidden. It collides with a dense molecular cloud, which triggers complex physical processes [1]. The impact on interstellar matter creates a region suitable for accelerating atomic components [1].

## Mapping and open questions

The structure was mapped with the MeerKAT radio telescope and the European VLBI Network. They revealed a formation extending one hundred light-years in length [1]. Records from the LHAASO observatory suggest the presence of particles with extraordinary energy in the same region of space [1].

Scientists assess that the violent interaction of the hidden jet with the cloud may generate intense gamma rays and push particles to energy levels without known precedent in the galaxy [1]. This is an assessment, not an established result: definitive confirmation of the link between the hidden jet and the accelerated particles still requires further analysis, and the data remain under evaluation [1].

According to the publication, the jet's direction toward Earth does not make the phenomenon a threat, since the distance of twelve thousand light-years is enough to dissipate any direct impact [1]. The authors regard the system as a natural laboratory for studying the evolution of extreme binary systems [1].

The list of features highlighted by the research teams includes the structure of about one hundred light-years, refined MeerKAT data, high-resolution mapping from the European VLBI Network, and a possible link to sources of ultra-high-energy gamma rays [1].
