To probe their Ly$\\alpha$ escape, we study the spatial profiles of Ly$\\alpha$ and UV continuum emission of 24 Green Pea galaxies using the Cosmic Origins Spectrograph (COS) on Hubble Space Telescope (HST). We extract the spatial profiles of Ly$\\alpha$ emission from their 2D COS spectra, and of UV continuum from both the 2D spectra and NUV images. The Ly$\\alpha$ emission shows more extended spatial profiles than the UV continuum in most Green Peas.
