This fond consist of newspaper clippings on the life time journeys of various scientists, astronauts, and professors from India and abroad. The articles also discuss the books that have been written about these individuals, highlighting their achievements and contributions to their respective fields.

This fond consist of the newspaper clippings on the coverage related to Halley comet.

The fond contain newspaper clippings on Astronomy: Ionosphere reading of stars. This states that the Indian astrophysicists propose that the Earth's ionosphere disturbances caused by X-ray bursts (XAY BIRT) could signal stellar activity. This alerts astronomers to phenomena like Sc X1's X-ray emissions. Detecting the impact of stars on the ionosphere is challenging due to background interference, with debates on ionization and magnetic field effects. Dr. Sastri and Dr. Murthy's experimental study reveals a significant magnetic field increase during a Sc X1 flare. Understanding the ionosphere's response to X-rays, including gamma rays from catastrophic stellar events, may offer a distinctive detection method for monitoring space events, aiding astronomers in decoding cosmic phenomena efficiently.

The observation note of Madras Equatorial observations on partial solar eclipse, lunar eclipse, occultation of planets and other astronomical objects. This fond significantly describes the disvoery of several planets, their regular activities, and changes and various astronomical phenomena. From these observations several detections were acrried out through screw detection techniques, interval analysis, and finding mean postitions of various stars.
