Thiruvananthapuram ∙ India has received its first message from the X-ray Polarimetry Satellite (EXPOSAT) launched on New Year’s Day. XSPECT, an instrument designed to study X-rays from various sources in the universe, has captured waves from the supernova remnant Cassiopeia A (Cas A).
On January 5, ISRO announced that Cass-A radiation detected by EXPECT detected the presence of magnesium, silicon, sulfur, argon, calcium, iron and neon. EXPECT hopes to uncover unsolved mysteries about the universe’s extreme energy phenomena.
Cassiopeia A is one of the most studied supernova remnants by humans. Cass A is located 11,000 light-years (9.46 trillion km) from Earth in the star cluster Cassiopeia. A supernova is a phenomenon in which giant stars explode for special reasons. After such an explosion, a supernova becomes a remnant (supernova remnant) when an outer layer of debris forms around the inner core of the stars.
