Chandra Discovers Source of Giant Star's Repeated Outbursts

• NASA's Chandra X-ray Observatory found the source of repeated outbursts from a giant, unstable star.
• The star, known as a luminous blue variable and supernova impostor, is located in the galaxy NGC 4559, about 30 million light-years from Earth.
• Chandra data revealed X-ray point sources, providing insights into the star's behavior.
• The star, AT 2016blu, is in the middle of the galaxy, surrounded by other objects captured by the Sloan Digital Sky Survey.
• This discovery helps astronomers understand the mechanisms behind the star's repeated outbursts.
