This artist’s impression depicts a star being torn apart by an intermediate-mass black hole (IMBH), surrounded by an accretion disc. This thin, rotating disc of material consists of the leftovers of a star that was ripped apart by the tidal forces of the black hole. Credit: ESA/Hubble, M. Kornmesser New […]

According to classical theories, these space giants would not have had the time to develop in the young Universe. Yet, observations say they were already present. A new study by SISSA proposes a response to the fascinating question. Credit: NASA/JPL-Caltech These space giants would not have had the time to […]

The image of a black hole has a bright ring of emission surrounding a “shadow” cast by the black hole. This ring is composed of a stack of increasingly sharp subrings that correspond to the number of orbits that photons took around the black hole before reaching the observer. Credit: […]

Galaxy NGC 4237, located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice’s Hair). Credit: ESA/Hubble & NASA, P. Erwin et al. This picture taken by the NASA/ESA Hubble Space Telescope, shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of […]

Astronomers using ESA’s XMM-Newton and NASA’s Chandra X-ray space observatories, along with radio telescopes on ground, have spotted the aftermath of the most powerful explosion ever seen in the Universe. The huge outburst occurred in the Ophiuchus galaxy cluster, a large cosmic conglomerate with thousands of galaxies, hot gas and dark […]

This image shows the X-ray outburst from the black hole MAXI J0637-043, detected by the REXIS instrument on NASA’s OSIRIS-REx spacecraft. The image was constructed using data collected by the X-ray spectrometer while REXIS was making observations of the space around asteroid Bennu on November 11, 2019. The outburst is […]

Artist’s conception of a dwarf galaxy, its shape distorted, most likely by a past interaction with another galaxy, and a massive black hole in its outskirts (pullout). The black hole is drawing in material that forms a rotating disk and generates jets of material propelled outward. Credit: Sophia Dagnello, NRAO/AUI/NSF […]
