‘All hope abandon, ye who enter here', Dante’s Divina Commedia.
The discovery that stars in other galaxies having such greater mass on average upends many previous assumptions about the wider universe.
The new imaging, the result of a multi-year collaboration between multiple specialized telescopes, is the first definitive evidence of the supermassive black hole at the center of the Milky Way.
Black holes can be hidden by energy sources called active galactic nuclei.
Many black holes are actually near impossible to detect. Now another team using the Hubble Space Telescope seems to have finally found something nobody has seen before.
Black holes have taken up around 1% of all ordinary (as in baryonic) matter in the universe.
Scientists at Israel’s Weizmann Institute have succeeded in witnessing the explosion of a massive Wolf-Rayet star
Sagittarius A* lies in the galactic center of the Milky Way and is a known source of radio waves, gamma rays and X-rays. But its irregular bursts follow no discernible pattern.
