Orderly Electromagnetic Waves Suddenly Emitted from the Depths of the Universe

At the beginning of the new year, countries around the world suddenly received orderly electromagnetic waves from the depths of the universe. After deciphering by scientists, they found that it was a brief notification letter from an extraterrestrial civilization. The notification letter said: "Dear Earth civilization, we are the Pabigonica star opposite you in the Milky Way. Our planet has been destroyed. As pacifists, we have been looking for a new home. After hundreds of thousands of years of searching, we have finally found a solar system suitable for civilization to survive. We will immigrate to Mars and arrive in about five years. We hope to live in peace with humans and jointly colonize and develop Mars."
