Type Ia supernovae are a central pillar of cosmology that is vital to the adoption of the LambdaCDM “Standard Model of cosmology”. However, they may also elucidate potential gaps in the theory. I will present recent results of the distance ladder constructed from SH0ES observations of Cepheids in combination with the sample of 1550 Pantheon+ supernovae. Ruthless attention paid to systematic uncertainties and recent leaps in progress of SNIa analyses have culminated in a 1km/s/Mpc constraint of the value of the Hubble constant, which has now crossed the significant 5 sigma threshold of discrepancy when compared to that of Planck+LambdaCDM.
