In the void of space,

\ndrawing all matter
\ninto its cosmic,

\nAround the rim

\nfanning the flames
\nwith heat
\nand fear
\nand change.
\nInvisible teeth
\nsinking deep

\ninescapable,

\nCloaked in dust,

\nwe pierce veils of starlight
\nexposing hidden shadows
\nwhere matter starts

Hydrogen cyanide isotopes (H13CN), shown in yellow, are found only around the black hole at the centre. Cyanide radicals (CN), shown in red, appear not only in the centre and a large-scale ring-shaped gas structure, but also along the bipolar jets extending from the centre towards the northeast (upper left) and southwest (lower right). Carbon monoxide isotopes (13CO), shown in blue, avoid the central region (Image Credit: ALMA (ESO\/NAOJ\/NRAO), NASA\/ESA Hubble Space Telescope, T. Nakajima et al.).<\/figcaption><\/figure>\n

This poem is inspired by recent research<\/a>, which has found that supermassive black holes alter galactic chemistry.<\/p>\n

Black holes are regions in space where gravity is so strong that nothing, not even light, can escape from them. Supermassive black holes are incredibly large versions of these mysterious entities and are usually found at the centre of galaxies. They have a mass equivalent to millions or even billions of our suns. These black holes influence their surroundings in various ways and play a crucial role in shaping the universe as we know it. Yet despite their immense size, black holes are very compact. Combined with the fact that they are so far away from Earth and often hidden behind galaxy dust, it becomes challenging to determine the makeup of the gas surrounding an active supermassive black hole.<\/p>\n

Researchers have now used the ALMA (Atacama Large Millimetre\/submillimetre Array) to look closely at a nearby galaxy named NGC 1068, which has an active supermassive black hole at its centre. They discovered that certain molecules are found in different quantities closer to the black hole compared to further away. For instance, molecules like silicon monoxide (SiO) and hydrogen cyanide (HCN) are more abundant closer to the black hole, while others, like carbon monoxide isotopes (13CO), are more abundant further away. This variation suggests that the environment near the black hole is hotter, possibly due to intense forces and shocks, thereby demonstrating how supermassive black holes in the middle of a galaxy can directly influence the arrangement of chemicals within that galaxy.<\/p>\n
