JWST has revealed a stunning population of bright galaxies at surprisinglyearly epochs, $z>10$, where few such sources were expected. Here we present themost distant example of this class yet -- MoM-z14, a luminous($M_{\rm{UV}}=-20.2$) source in the COSMOS legacy field at$z_{\rm{spec}}=14.44^{+0.02}_{-0.02}$ that expands the observational frontierto a mere 280 million years after the Big Bang. The redshift is confirmed withNIRSpec/prism spectroscopy through a sharp Lyman-$\alpha$ break and$\approx3\sigma$ detections of five rest-UV emission lines. The number densityof bright $z_{\rm{spec}}\approx14-15$ sources implied by our "Mirage orMiracle" survey spanning $\approx350$ arcmin$^{2}$ is $>100\times$ larger($182^{+329}_{-105}\times$) than pre-JWST consensus models. The high EWs of UVlines (${\approx}15{-}35$ \AA) signal a rising star-formation history, with a${\approx}10\times$ increase in the last 5 Myr($\rm{SFR_{\rm{5Myr}}}/\rm{SFR_{\rm{50Myr}}}=9.9^{+3.0}_{-5.8}$). The source isextremely compact (circularized $r_{\rm{e}} = 74^{+15}_{-12}$ pc), and yetresolved, suggesting an AGN is not the dominant source of light. The steep UVslope ($\beta=-2.5^{+0.2}_{-0.2}$) implies negligible dust attenuation and ayoung stellar population. The absence of a strong damping wing may indicatethat the immediate surroundings of MoM-z14 are partially ionized at a redshiftwhere virtually every reionization model predicts a $\approx100\%$ neutralfraction. The nitrogen emission and highly super-solar [N/C]$>1$ hint at anabundance pattern similar to local globular clusters that may have once hostedluminous supermassive stars. Since this abundance pattern is also common amongthe most ancient stars born in the Milky Way, we may be directly witnessing theformation of such stars in dense clusters, connecting galaxy evolution acrossthe entire sweep of cosmic time.
