In any globular cluster, all its stars formed at the same time, from the same cloud of gas. The Milky Way has around 150 known globular clusters; these objects are excellent tools for studying, for example, the history of the Universe, or the dark matter content of the galaxies they orbit.

Black hole jets are powerful streams of particles and magnetic fields ejected from the regions surrounding supermassive black holes. These jets, often spanning hundreds of thousands of light-years, play a crucial role in shaping the environments around galaxies by injecting energy into the intergalactic medium.

An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light- years. That is equivalent to lining up 140 Milky Way galaxies back-to-back. Credit: E. Wernquist / D. Nelson (IllustrisTNG Collaboration) / M. Oei

Black hole jets equivalent to 140 Milky Way galaxies discovered coming from far-away galaxyCalTech With only 117 in MLB history, an immaculate inning is rarer than a no-hitter. What to expect during perimenopause, including lesser-known symptoms and how long this phase lasts.

Astronomers have detected a supermassive black hole starving its galaxy of gas, halting star formation in the early universe.

Black holes suck in anything and everything that comes near them, even light cannot escape after crossing one of their event horizons, However they also produce massive outflows of plasma and one of those astrophysical jets just produced the largest megastructure ever observed.
