TL;DR

The universe's peak star production occurred approximately 10 billion years ago during the 'Cosmic Noon.'
Currently, about 90% of stars are in their main stable phase, and 95% of all stars that will ever exist have already been born.
The rate of new star formation is declining significantly.
Galaxies are converting gas into stars at a decreasing rate.
The universe is dominated by older stars, and fewer new stars are being formed.
The process of star formation relies on available material, and with each generation, less fuel remains.
The 'Heat Death' or 'Great Freeze' is a theory suggesting the universe will eventually reach a state of thermal equilibrium due to energy dispersal.
Star formation is expected to continue for billions of years, but at a diminishing rate, long after our Sun has died.
The ultimate end of the universe, according to some theories, could be trillions of years away.
