Exploring Cosmic Signals: Insights from Multiwave Astronomy and SETI Research

This article delves into the fascinating realm of multiwave astronomy, highlighting key images and maps from various observatories, including infrared, radio, optical, X-ray, and gamma-ray observations of the Milky Way and Crab Nebula. Additionally, it discusses the groundbreaking Arecibo Message sent in 1974, featuring the strongest man-made signal ever transmitted, aimed at interstellar communication. By examining these cosmic phenomena through different wavelengths, we gain a deeper understanding of our universe and search for potential extraterrestrial life.

  3. The image of the IR man is from the Infrared Processing and Analysis Center at the California Institute of Technology. • The Radio survey, courtesy of The Max Planck Institute for Radio Astronomy. • The Infrared image of the Milky Way was taken by the Infrared Astronomical Satellite (IRAS). • The Optical all-sky panoramic image of the Milky Way galaxy was created at Lund Observatory in the 1940s. • The X-ray image was taken by the German Roentgen Satellite (ROSAT) • The gamma-ray map was generated by the EGRET (Energetic Gamma-Ray Experiment Telescope) • The radio image of the Crab Nebula is courtesy of the National Radio Astronomy Observatory. • The optical image of the crab nebula is courtesy of the Anglo-Australian Observatory. • The ultraviolet photograph of the Crab Nebula is from the Ultraviolet Imaging Telescope. • The X-ray image of the Crab Nebula is from ROSAT.

  4. SETI • The signal, transmitted at 2380 megahertz with a duration of 169 seconds, delivered an effective power of 3 trillion watts, the strongest man-made signal ever sent. • 25,000-year-long journey to the Great Cluster in Hercules. • Sent from Arecibo Observatory on November 16, 1974
