[3] The cluster acts as a power magnifier thanks to the gravitational lensing effect.

[1][4] In one of these strongly magnified images of the Sunburst galaxy, astronomers have identified the most luminous star known to date, Godzilla.

Emission from Godzilla's nebula indicates unusually pressurized ionized gas highly enriched with nitrogen.

The Sunburst galaxy hosts a massive star cluster that is only 2-4 Myr[7][8] after formation.

The star cluster is very compact, weighing tens of millions of solar masses while having a radius no larger than 10 parsecs.
