Black hole

A black hole is an object in the universe that's gravity haes sic a strang pou that e'en licht canna win awa frae it. Short syne, mony astronomers didna e'en ken gin thay kythed, but throu uisin modren prospects an leukin til the universe, thay fund objects wi sic a strang gravity that coud be nocht but black holes.

The supermassive black hole in the core o supergiant elliptical galaxy Messier 87, wi a mass aboot 7 billion times that o the Sun.[1] It wis the first black hole eemage frae the Event Horizon Telescope released (10 Apryle 2019).[2][3] Veesible are the crescent-shapit emission raing an central shaidae, that are gravitationally distortit views o the black hole's photon raing an the photon captur zone o its event horizon. The crescent shape arises frae the black hole's rotation;[3] the shaidae is aboot 2.5 times the diameter o the event horizon.[4]

Some Scots leid enthusiasts hae cleckit the neologism pitmirk thirl for black holes.
