astronomically

Hugely, like galaxies

Astronomically means to an extreme or enormous degree, emphasizing vast scale: astronomically high prices, astronomically unlikely odds.

The word borrows from astronomy, where distances and quantities are so immense they defy everyday comprehension.

Something that rises astronomically increases dramatically: Housing costs have risen astronomically.
