The item was about the IIA astronomers detected an expanding disc or a shell of gas around the supernova 1987A in the large Magellanic cloud with a velocity of 650km per second.

This item was about the investigation conducted by Society, they have found a possible relationship between C V Raman and S Chandrasekhar. According to their findings, S Chandrasekhar, who recently won the Nobel Prize, was a nephew of Sir C V Raman. The investigation also revealed that every member of Sir Raman's family has made some contribution to society in different ways.

This item was about supernova, that was photographed from Kavalur observatory before and after the appearance 1987A. The supernova is seen close to the tarantula nebula, the brightest nebulosity in the photographs.

This fond consist of newspaper clippings on the discoveries that was made from the indian soil in early 17th century.

This item was about the French Father Richaud made the first astronomical discovery on Indian soil. In 1689, when he discovered the double star Alpha Centauri using a 12-foot telescope in Pondicherry. He also determined the latitude and longitude of Pondicherry.

This item was about a supernova, an awesome explosion of a star, which occurred 186,000 years ago, was sighted by scientists from kavalur observatory. It is significant in that this is the first time it is known to have occurred in the large magellanic cloud.

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.

This item talks about the shell of gas around a supernova. The supernova 1987A is being monitored photometrically and spectroscopically from Vainu Bappu Observatory Kavalur.
