Metsähovi Radio Telescope, located in the forests outside Greater Helsinki in Finland, is one of the telescopes used to take the first image of the M87 black hole together with its powerful jet. The image is formed from measurements gathered at 3.5mm radio wavelength by a network of radio telescopes around the world. The results were published in Nature on 26 April 2023.

A team of astronomers captured a detailed image of a ribbon-like jet emerging from the heart of OJ 287, revealing extreme energy and motion near the black hole. The study sheds new light on supermassive black holes and their powerful jets, potentially offering clues to binary black hole mergers.
Astronomers have discovered a new black hole behavior where a smaller black hole repeatedly punches through the disk of a larger black hole, releasing plumes of gas. The findings challenge conventional views on black hole accretion disks and suggest they may be more varied in their contents.
A team of scientists captured an astonishing image of a gamma-ray flare emanating from the supermassive black hole at the center of galaxy M87. The flare was tens of millions of times larger than the event horizon and lasted about three days, providing crucial insights into particle acceleration near black holes.
Astronomers have observed a black hole triple system for the first time, featuring a central black hole consuming a star and a distant companion that orbits every 70,000 years. The discovery raises questions about the origins of the black hole itself.
A research team at the Purple Mountain Observatory confirms Stephen Hawking's prediction that a black hole's horizon area cannot shrink when two black holes merge. The analysis of GW230814 shows strong support for the black-hole area law, validating general relativity in extreme astrophysical environments.
Astronomers observe low-mass supermassive black hole consuming matter at over 40 times the theoretical limit, providing new insights into rapidly growing black holes. The discovery reveals a possible mechanism for black holes to exceed their Eddington limit, sparking further investigation.
