Abstract: In this short paper we prove that, for $ 3 \le N \le 9$, the problem $ -\Delta u = e^u$ on the entire Euclidean space $ \mathbb{R}^N$ does not admit any solution stable outside a compact set of $ \mathbb{R}^N$. This result is obtained without making any assumption about the boundedness of solutions. Furthermore, as a consequence of our analysis, we also prove the non-existence of finite Morse Index solutions for the considered problem. We then use our results to give some applications to bounded domain problems.
