Star Defies Supernova, Shines Brighter Than Before

Quick Summary

• The Hubble Space Telescope captured a detailed image of the spiral galaxy NGC 1309, located approximately 100 million light-years away in the constellation Eridanus.
• The image showcases bluish stars, dark brown gas clouds, a pearly white center, and background galaxies. Only one nearby Milky Way star is identifiable by its distinctive diffraction spikes.
• NGC 1309 has been imaged by Hubble multiple times before, including in 2006 and 2014.Its scientific significance lies in observations of two supernovae: SN 2002fk and SN 2012Z.
• SN 2002fk was identified as a standard type Ia supernova linked to the explosion of a white dwarf’s core.
• SN 2012Z was an anomalous Type Iax supernova that left behind a surviving “zombie star,” which shone brighter post-explosion-a rare revelation made possible by years of Hubble observations.

indian Opinion Analysis

India’s growing interest in space science could find inspiration from NASA’s detailed study of celestial phenomena such as NGC 1309 and its supernova events-key topics in understanding cosmic evolution and stellar life cycles. These observations demonstrate how cutting-edge technology aids discoveries such as “zombie stars” or pre-supernova imaging breakthroughs, emphasizing investment needs for advanced telescopes and interstellar research capabilities globally.

Such studies may also strengthen international collaborations between India’s burgeoning space programs (e.g.,ISRO) and established organizations like NASA or ESA to further explore global questions about galaxies’ dynamics across vast distances-valuable for academic growth but also potential advances in space exploration technologies applicable on Earth.
