FUV/NUV GALEX colour (left) and continuum-subtracted Hα (VESTIGE; right) magnified images of the extraplanar star-forming regions (marked with green circles) in the south-west quadrant of NGC 4254. The UV colour image shows that these regions have very blue colours, and are thus dominated by young stellar populations (≲100 Myr). Half of them, however, are undetected in Hα, indicating that their typical age is 10 Myr ≲ age ≲ 100 Myr.
